5 Expert Chainsaw Tips to Keep Things In Check

5 Expert Chainsaw Maintenance Tips

Chainsaws are great tools – when they’re working properly. Here are five chainsaw-maintenance tips to keep your chainsaw cutting strong.

Keep the chain sharp

Anyone who has tried forcing a dull chain through wood knows the importance of a sharp chain.

Properly sharpening a chain is an art form, so if you don’t want a collection of useless chains hanging on your garage wall, visit a professional.

It’ll likely cost you less than $10 and save you a ton of grief.

Oh, and the AMSOIL Bar & Chain oil keeps the chain cooler thus sharper longer. (We keep both gallons and quarts in Sioux Falls)

filing chain saw teeth

However, if you’re like me and enjoy the challenge of learning a new craft, be sure to…

  • Use the proper file size. The box the chain came in or your owner’s manual are two places to find that information.
  • File at the correct angle. You can purchase a file gauge at most home centers that ensures you hold the file correctly.
  • File each tooth the same number of file strokes (typically 3-6).
  • Be careful with the depth gauges (the protrusions directly in front of each tooth). If you file them too much, the saw can bite too deeply into the wood and stall or, worse, pull you off balance. Again, use a gauge to ensure you sharpen the depth gauges correctly.

 

Properly tension the chain

A chain that’s too tight can bind and stall the saw. On a non-roller-tip bar, an over-tightened chain can overheat.

When adjusting the chain, hold the tip of the bar up as far as it goes and tighten the tensioning screw until you’ve taken the slack out of the underside of the bar.

soaking chain in oil before use

Soak a new chain in bar and chain oil when breaking it in.

Break in a new chain

When it’s time to replace the chain, break it in first by soaking it in bar and chain oil for a couple hours. This ensures all the pivot points are well lubricated.

Then, hang the chain from a nail and let the excess oil drip back into the pan.

Install and tension the chain and run until warm.

The chain will loosen as it heats, so shut the saw down and tension the chain again.

Then, perform light-duty work, like cutting limbs and small branches for 30 minutes or so. Tension the chain again, and you’re ready to dive into the heavy-duty work.

Clean the air filter

Keeping the air filter clean is one of the most important parts of chainsaw maintenance to extend saw life and increase performance.

It’s the only line of defense against the engine ingesting sawdust and dirt, which can plug the carburetor and cause the saw to start hard and run poorly. Contaminants can also wreck the piston rings, causing the engine to lose compression, reducing power.

Many saws have a screen as opposed to a foam or paper filter. In these cases, use an air compressor to direct air through the filter backward to prevent lodging debris deeper into the media.

If you don’t have an air compressor, tap the filter on the edge of a workbench. If you have a foam or paper filter, replace it often – it’s far less expensive than replacing the entire saw.

Find out why different chainsaws have different oil mix ratios.

Use fresh gasoline for best chainsaw maintenance

Most homeowners’ chainsaws spend far more time sitting in the garage than cutting in the woods.

As gas/oil ages, gasoline can breakdown in as few as 30 days, creating gums and varnish that plug the carburetor and lead to hard starts and rough running.

Mix only enough fuel to last 30 days. Better still, use a two-stoke oil formulated with a gasoline stabilizer, such as AMSOIL SABER® Professional Synthetic 2-Stroke Oil.

Not only is SABER Professional formulated with stabilizer, it also fights carbon to keep the exhaust port and spark-arrestor screen (if equipped) clean for maximum engine operability and power. Using a premium two-stroke oil is an overlooked, but vital, part of chainsaw maintenance.

You can also treat fuel with an additive designed to stabilize fuel, like AMSOIL Quickshot®. Both products keep gas fresh up to six months.

Weed Eater Won’t Start? Try This

We’ve all been there – Weed Eater Starting Foes!

No matter what you call it – weed eater, weed whacker, string trimmer – chances are at some point it won’t start. Few things are more annoying than destroying your shoulder trying to start the weed eater when there’s work to do.

Fortunately, gasoline weed-eater engines are pretty simple, so most DIYers with a few tools and some basic know-how can get a stubborn trimmer running.

Here are our guidelines for troubleshooting a weed eater that won’t start

1) Check the gasoline

Gasoline can break down in as little as 30 days, especially today’s ethanol-containing gas. Homeowners sometimes stash their string trimmer in the garage at season’s end without stabilizing the gas. Oxygen has all winter to break down and ruin the gasoline, leaving you with a trimmer that won’t start in the spring.

If your trimmer falls into this category, empty the old gas from the fuel tank and replace it with fresh fuel.

2) Clean the carburetor

Once gas breaks down, varnish, gums and other debris can form inside the carburetor and clog the tiny fuel passages. This prevents fuel from reaching the combustion chamber and igniting.

Remove the air filter and spray carburetor cleaner into the intake. Let it sit for several minutes to help loosen and dissolve varnish. Replace the filter and try starting the trimmer.

If this doesn’t solve the problem, consider disassembling the carburetor to give it a more thorough cleaning.

Beware, however – taking apart a carburetor marks a point-of-no-return, of sorts. Understanding how the delicate gaskets, tiny screws and needle valves go back together can be a challenge, even on a relatively simple string-trimmer carburetor. Take pictures with your phone throughout the process to help reassembly. Clean all the openings and passages with carburetor cleaner.

If you’re reluctant to take apart the carb, visit the servicing dealer.

3) Clean or replace the spark plug

Oil deposits and carbon can foul the spark plug in a two-stroke engine if a low-quality oil is used. Deposits on the electrode prevent the plug from firing properly, which can reduce performance or prevent the engine from running altogether.

Plugs are inexpensive, so replace it if it’s fouled. If you don’t have a new plug available, clean the deposits from the electrode with light-duty sandpaper and check the gap. Consult the owner’s manual for the correct gap size.

If you know the spark plug is good, but the engine still doesn’t produce spark, the coil is likely to blame and requires replacement.

4) Clean or replace the air filter

A clogged air filter prevents the engine from receiving sufficient air to operate properly.

Before removing the air filter, brush away loose debris from around the filter cover and filter element. Tap rigid filters on a tabletop or the palm of your hand to dislodge any dirt or debris. Compressed air also works well. Make sure you direct air through the filter from the inside to avoid lodging debris deeper in the filter.

Avoid washing paper filters as this can collapse their micro-fine structure. Foam filters, however, can easily be washed using mild detergent and warm water.

As with the spark plug, however, replacement is often the best practice, especially if the filter is excessively dirty.

5) Clean the spark-arrestor screen

On many trimmers, a small screen covers the exhaust outlet and prevents sparks from exiting the muffler and potentially starting a fire.

As with plug fouling, too much oil in the gasoline, inferior oil and continued low-rpm operation can plug the screen with carbon deposits. This prevents exhaust-gas flow, which leads to power loss. In extreme cases, heavy deposits choke airflow enough to leave you with a weed eater that won’t start.

To fix the problem, remove the spark arrestor screen and spray it with a heavy-duty cleaner, like AMSOIL Power Foam®, to soften the deposits before cleaning the screen with an abrasive pad. Reinstall the screen and test the trimmer.

Replace the screen altogether if it’s excessively plugged with carbon.

6) Switch to a better two-stroke oil

Low-quality oil that leads to heavy carbon is often to blame for most of the problems on this list.

Using a good two-stroke oil that burns cleanly and helps prevent carbon deposits is one of the easiest maintenance practices you can perform to ensure your trimmer starts easily, runs well and last for years.

Leading the Way in the Wind Industry

Making The Wind Industry Profitable

Nearly 58,000 wind turbines dot the American landscape. Nearly 50 percent of those now use AMSOIL synthetic lubricants in their gearboxes. Here´s the story of how we shook up the wind industry – and how it benefits you.

We dove into the wind market more than a decade ago for the same reasons we enter most markets: to solve a problem. At the time, wind farm managers were struggling to find a wind turbine gearbox lubricant capable of delivering superior protection without requiring frequent and expensive changes. Fully appreciating the challenge requires understanding how a wind turbine gearbox works.

Wind turbine gearbox 101

If you’ve ever driven past a wind farm, you’ve noticed how slowly wind turbine blades turn – typically 10-18 rpm. The generator inside the turbine’s nacelle (the housing atop the tower), however, requires up to 1,500 rpm to produce the turbine’s rated power. The gearbox increases rotational speed from the low-rpm turbine blades to the highrpm electric generator. It uses a variety of planetary gears, helical gears and bearings to accomplish this.

All those moving parts must withstand tremendous torque and high speeds while operating in hot, humid, wet environments or sub-zero temperatures – sometimes all of the above throughout the year. Gear lube can quickly fail in such conditions.

That was precisely the case with the predominant windturbine gear lube on the market at the time. It tended to absorb moisture, which led to additives separating from the lubricant (called additive dropout). This leads to a form of fatigue failure called micropitting that can cause gears to fail. In fact, at that time, a wind-farm manager could expect 30-40 percent of the gearboxes in his turbines to fail within three to five years. This is unacceptable considering that, along with crane costs, replacing a wind turbine gearbox costs up to $500,000.

To help prolong gearbox life, managers resorted to frequent gear-lube changes – typically every two to three years. That may not sound unreasonable until you understand the toll a single lubricant change takes. First, the turbine has to be shut down, which reduces profitability. A team of trained technicians must then mobilize a specially designed truck capable of pumping the new lubricant to the gearbox (up to 300 feet above the ground) while draining the old oil. Not only that, the gearbox requires flushing to remove contaminants, which adds additional time and complexity. Changing oil in just one gearbox can cost thousands of dollars. Changing oil in every gearbox on a wind farm quickly becomes cost-prohibitive.

Building a better lubricant

We went to work developing a better gear lubricant. In addition to years of lab testing, the lubricant was installed in seven wind turbines located in the Midwest. The turbines had been using a competitor’s oil and were in rough shape. In fact, the wind farm manager later told us he had expected the gearboxes to fail within six months of testing. Instead, the AMSOIL product performed well and the turbines continued running. We monitored lubricant and turbine performance every month.  The process uncovered several costly hurdles to servicing wind farms. For example, personnel must complete safety training, earn certification and carry millions of dollars of liability insurance simply to set foot on a wind farm, let alone climb a tower. In addition, wind farm managers expect suppliers to act as technical consultants and help them develop procedures for improving efficiency. We quickly realized that servicing wind farms requires a team of full-time, specialized experts. That’s why we handle sales to wind farms corporately rather than through independent Dealers.

Despite years of severe service, the lubricant continued performing flawlessly. In total, the lubricant was in use for nine years without being changed and without incident. Recently, the wind farm elected to decommission the seven turbines to perform infrastructure upgrades; however, the lubricant was still in great condition and performing well until its final day of use.

Our test data impressed the biggest and most prestigious manufacturers in the world. We have since earned approvals from nearly every major turbine manufacturer and gearbox manufacturer, including Siemens*, Vestas*, Flender*, Nanjing Gear* and ZF*. This was a huge step since wind farm managers won’t use non-approved oils in their turbines given the astronomical costs should something fail. Our gear lube is also the factory fill for one of the world´s largest turbine manufacturers, as well as the run-in oil at nearly every major gearbox OEM that supplies the global wind industry. We continue to work toward earning more factory-fill agreements.  AMSOIL products are now installed in nearly 50 percent of all wind turbines in the U.S., in addition to turbines in Europe, China, India, Brazil and more. We’re proud to say that AMSOIL products have never caused a gearbox failure. That’s a tremendous achievement considering the state of the industry prior to our arrival.

What good is it for me?

You might be thinking, “That’s great for AMSOIL INC., but how does it help my Dealership?” There are several ways.

1) Increased expertise influences all AMSOIL products

The insights we’ve gleaned from our involvement in the wind industry influence additional product formulations. For example, we applied the advanced chemistry of our wind-turbine gear lubricant to the passenger car/light truck market via SEVERE GEAR® Synthetic Gear Lube. The chemistry that impressed the toughest critics in one of the world’s most demanding industries influenced the chemistry in each easy-pack of SEVERE GEAR. Developing and testing synthetic technology in wind turbines builds our knowledge and helps us continue to improve our full line of world-class synthetic lubricants.

2) Brand validation

Our leadership role in the wind industry strengthens the AMSOIL brand and helps validate your efforts in the field. Additionally, it shows that our size and influence is larger than some people think, boosting your credibility. Tell prospects and customers that the biggest and most prestigious manufacturers in the wind industry selected AMSOIL from all the lubricant manufacturers in the world to develop a gear lube for their gearboxes. Point out that AMSOIL lubricants are installed in nearly 50 percent of U.S. wind turbines. This level of credibility speaks volumes about our product quality. Ask prospects, “If AMSOIL synthetic lubricants perform that well in wind turbines, imagine how well they can perform in your vehicles and equipment.”

3) Improves company image

While it may not be at the forefront of many enthusiasts’ minds, many customers actively look for companies that support sustainability. By servicing renewable-energy assets and maintaining a leadership role in the industry, we strengthen our image, which reflects well upon Dealers.

4) Helps keep costs down

A single wind farm can require thousands of gallons of lubricants. To meet demand, we purchase increased volumes of raw materials at a time, helping reduce purchasing costs. Manufacturing to meet increased demand also leads to greater production efficiency, which further holds costs in check. We pass the savings on to you and your customers.

We plan to continue growing our presence in the wind industry. It’s a key part of our strategy to diversify and strengthen the company, which ensures the viability of the Dealer opportunity for years to come.

WHY CAN’T DEALERS SELL TO WIND FARMS?

We’re as committed to the Dealer opportunity as ever. But explosing Dealers to the financial and safety risks inherent to the wind industry would be irresponsible. For the following reasons, it’s best for everyone that we handle the wind market corporately.

CUSTOMERS REQUIRE UNPRECEDENTED SERVICE

Selling lubricants is just the start. Businesses must sign complex terms-and-conditions agreements and carry expensive insurance policies. They must also maintain a large inventory of products while providing payment terms. In addition, businesses are expected to develop oil-sampling procedures, obtain oil samples and create gearbox-flushing procedures, among other value-added services. A business is seen as a partner available to help wind-industry personnel uncover ways to maximize turbine efficiency. It must provide on-site technical analysis and actively work to advance the industry, not just sell lubricants. Simply entering a turbine is dangerous and requires extensive training and certification. These restrictions are in place to ensure maximum safety when working in turbines 300 feet high and beyond.

THE MARKET REQUIRES SPECIALIZED KNOWLEDGE

Gearboxes and other components use cutting-edge technologies accessible only to industry experts. Personnel must understand particle-count testing, oil analysis interpretation, troubleshooting and other complex disciplines. Mechanical failures resulting from incorrect product recommendations, for example, can carry liability costs in excess of $500,000 per turbine. Dealers aren´t positioned to absorb this level of risk.

THE MARKET CONTAINS RELATIVELY FEW POTENTIAL CUSTOMERS

While growing, the wind market contains a relatively small number of potential accounts compared to traditional markets. Pursuing a wind farm not only will lead to disappointment, it will distract Dealers from approaching potential customers they’re much more likely to secure.

While there are Dealers who are fully capable of executing aspects of doing business with wind farms, the overall demands and liabilities are too great.

 

AMSOIL has never caused a gearbox failure. That’s a tremendous achievement considering the state of the industry prior to our arrival.

AMSOIL SABER® Professional Cuts Costs While Helping Your Equipment Run

AMSOIL SABER® Professional – Simplify your 2-cycle Oil

Anyone who’s owned or operated a two-stroke string trimmer, chainsaw, blower or other piece of equipment has been there before. You repeatedly pull the starter cord and adjust the choke, but it’s still hard to start. And, when it finally fires up, it runs rough and threatens to quit. Hard-starting, rough-running equipment is not only frustrating, it lacks the power to work as efficiently as you want.

What causes hard-starting equipment?

•Convenience of one mix ratio for all equipment
•Cuts costs by 50% or more
•Clean, protected power

Heavy carbon deposits in the exhaust port and on the spark arrestor screen are often to blame. Here’s how it works.

Internal combustion engines require a steady supply of air to run properly and produce maximum power. The engine draws air through the intake and burns it, along with the fuel/oil, in the combustion chamber. The moving piston expels the exhaust gases through the exhaust port and spark arrestor screen on the muffler. In a properly running engine, this happens thousands of times a minute and goes unnoticed by the operator.

Two-stroke oils with poor detergency properties, however, can allow carbon deposits to build-up in the exhaust port and on the spark arrestor screen. Carbon chokes off airflow, which causes the engine to slowly lose power and run poorly. Soon, it becomes hard to start or fails to run altogether unless you clean the exhaust port (which requires removing the muffler) and spark arrestor screen. Most operators don’t want to waste time cleaning deposits, especially busy professional landscapers who need to complete jobs quickly and efficiently.

AMSOIL SABER Professional fights carbon

AMSOIL SABER Professional Synthetic 2-Stroke Oil is proven to solve this problem. It features excellent detergency to fight power-robbing carbon deposits and keep exhaust ports and spark arrestor screens clean for easy starting and maximum power.

As the images show, SABER Professional mixed at 100:1 nearly prevented deposits, while ECHO* Power Blend* XTended Life* Universal 2-Stroke Oil mixed at 50:1 resulted in heavy deposits and considerable airflow loss. In fact, heavy deposits on the screen from the string trimmer using ECHO Power Blend  (see image) prevented the trimmer from starting, requiring the screen to be replaced.

Spend less for better performance

See the full test results in the ECHO 100:1 String Trimmer Technical Study. Results prove that SABER Professional mixed at 100:1 fights carbon deposits better than ECHO Power Blend at 50:1 while also delivering outstanding wear protection. By using a 100:1 mix ratio, SABER Professional provides the added benefit of cutting oil costs by 50 percent or more compared to using a 50:1 mix ratio.

Experience the SABER’s edge and ensure your two-stroke equipment starts easily and runs strong.

NEW PRODUCTS EXPAND OPPORTUNITY

To better target landscapers, contractors and other professionals who rely on small engines to make a living, AMSOIL Formula 4-Stroke® Synthetic Small Engine Oil (ASE) has been updated with a new name, label and packaging. Its formulation remains unchanged. Its current pricing remains in effect until April 1, at which time it will be updated to the pricing shown on the facing page. New labels will become available as current inventory is depleted. Launching March 6, new AMSOIL 20W-50 Zero-Turn Synthetic Hydrostatic Transmission Fluid (AHF) and AMSOIL 10W-40 Synthetic Small-Engine Oil (ASF) round out the new family of AMSOIL commercial-grade products.


Landscapers, contractors and other professionals are some of our best potential customers. They’re under tremendous pressure to complete jobs on time and up to standards, which spurs them to seek products that help them safely cut costs without affecting quality.

AMSOIL products offer the perfect solution. To drive that point home and help expand your opportunities, we’ve introduced a new line of commercialgrade products that help professionals cut costs through maximum equipment power and service life.

Power Play

On a job site, power equals efficiency. Few pieces of equipment in a landscaper’s arsenal embody this axiom like the zero-turn or stand-on mower. Next to their truck, it’s the most expensive piece of equipment they own. These workhorses allow crews to quickly produce professional-looking lawns and grounds through a combination of precision, power and speed.

Showing professionals how you can help them maintain power in their mowers and other equipment is one of your most important steps toward turning prospects into customers. Mowers and equipment that wear out and suffer power loss increase the amount of time and effort needed to complete jobs on time, forcing crews to work even harder and faster to stay on schedule.

Continuous operation in hot, dirty conditions can lead to deposits and wear that reduce engine compression, robbing the engine of power. Over time, mowers become less efficient, require more maintenance and eventually wear out altogether.

Clean, Protected Power

AMSOIL Synthetic Small-Engine Oil’s purpose-built formulation protects against wear, heat and carbon deposits, outperforming conventional oils. It’s designed to maintain power and promote long equipment life for professionals who depend on small engines to make a living. As shown to the right, it helps eliminate power-robbing deposits and wear in severe service, helping preserve power and boost profitability.

Fights Deposits & Preserves Power Better than Competitive Products

The piston and rings are virtually free of deposits
and wear after 500 hours of severe-service
testing in the Kawasaki* FX 730 V engine.


Specialized Transmission Fluid

Hydrostatic transmission performance is just as important to job-site efficiency as engine protection. Many professionals may be using a traditional motor oil in their hydrostatic transmissions instead of a purpose-built transmission fluid. Motor oils, however, may not deliver the smooth control and responsive power operators need to complete jobs quickly.


Oil pressure drives the wheel motors in most zero-turn mowers, meaning professionals must use a shear-stable fluid that resists viscosity loss and wear to ensure best performance. However, the intense heat – up to 230ºF – and shearing conditions common to hydrostatic transmissions can cause some fluids to thin, which reduces oil pressure. In addition, wear can open the tight tolerances inside the transmission, further reducing oil pressure. Operators soon notice one mower wheel moving more slowly than the other, which requires constant correction to mow in a straight line, or the mower slowing down altogether and becoming less responsive.

AMSOIL 20W-50 Zero-Turn Hydrostatic Transmission Fluid is specially built to solve this problem. Its synthetic, highzinc formula fights wear and resists thinning, helping maintain mower speed and responsiveness better than motor oils. It lasts up to 2X original equipment manufacturer (OEM) recommendations, helping save time and money.

 

 

 

DEALER ACTION PLAN

• Although the family of commercialgrade synthetic lubricants works great for homeowners, focus your time on landscapers, contractors and others who rely on their equipment to make a living. They’re more likely to buy a premium product.

• Sell the products’ ability to maintain equipment power and cut costs. These are the benefits professionals value most.

• Showing potential customers how they can cut costs 50 percent or more using SABER Professional Synthetic 2-Stroke Oil (see sidebar) is a great way to start a business conversation that may lead to sales of other products.

• When talking to potential customers, don’t lead with a technical discussion about the results of the new SABER Professional testing. First, create curiosity by asking good questions, such as, “Do you have any equipment that requires more maintenance than others?” Their answer may naturally lead you to show them how SABER Professional reduces carbon and maintains engine power.

• View the Dealer Sales Brief in the Dealer Zone (Training>Training Materials>Dealer Sales Briefs) for more selling strategies.

AMSOIL SABER® CUTS COSTS 50 PERCENT OR MORE

Using a leaner mix ratio than the 50:1 ratio typically recommended by manufacturers can translate into significant savings. For this strategy to work, however, the oil must protect modern, hot-running two-stroke equipment from the negative effects of heat, including wear and power-robbing exhaust-port deposits. Otherwise, equipment becomes difficult to start and lacks sufficient power to get the job done, frustrating workers. Eventually, equipment can quit running completely.

The new ECHO* 100:1 String Trimmer Technical Study (G3470) proves SABER Professional Synthetic 2-Stroke Oil’s (ATP) ability to deliver clean, protected power at a 100:1 mix ratio, allowing professionals to cut oil costs 50 percent or more compared to traditional 50:1 mix ratios. Use these results to show potential customers how SABER Professional can help them save while delivering better protection. View the digital version free at www.amsoil.com/performancetests.aspx.

DID YOU KNOW?

Handheld two-stroke equipment often has a spark arrestor screen on the muffler. As the name indicates, it prevents sparks from exiting the muffler and starting a wildfire. Hot exhaust gases flow through the screen, meaning oils with poor detergency can allow deposit formation. A plugged screen restricts airflow, reducing engine power and, eventually, causes it to quit altogether. In fact, heavy deposits on the screen from the string trimmer using ECHO Power Blend* XTended Life* Universal 2-Stroke Oil (above) prevented the trimmer from starting, requiring the screen to be replaced. SABER Professional, in contrast, virtually prevented screen deposits for clean, protected power.
