5 Expert Chainsaw Maintenance Tips

John Baker|

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)

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.

Buy SABER Professional

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.

Common Fixes for a Transmission that Jerks or Hesitates

Common Fixes for a Transmission that Jerks or Hesitates

John Baker|

The AMSOIL ATF is one of our best sellers in the Sioux Falls store. Thanks to you many local transmission shops are now suggesting it to their customers. You can pick up here and take to your favorite transmission shop.

Here are a few common reasons why your transmission may shift erratically, jerk or hesitate.

• Low fluid level
• Depleted fluid frictional properties
• Poor cold-temperature fluidity

Start with the easiest fix

There’s an old adage when troubleshooting: start with the least expensive and simplest fix. In this case, check the transmission fluid level first. Low fluid can prevent the transmission from shifting properly. It’s important to find out why the fluid is low and fix any problems. It could be a leaky seal or other mechanical defect. Otherwise, adding new fluid won’t ultimately solve the problem.

Worn fluid equals poor shift quality

Transmission fluid that has aged and lost some of its frictional properties can also lead to poor shift quality. When your vehicle’s computer tells the transmission to shift gears, hydraulic pressure (provided by the fluid) squeezes a series of plates together inside a clutch pack to connect the engine to the transmission output shaft and route power to the wheels. The fluid’s frictional properties play a vital role in ensuring the clutch plates bind together properly and gear shifts occur seamlessly.

Over time, the fluid’s frictional properties can degrade, leading to elongated, jerky or inconsistent shifts. In this case, it’s time for a fluid change.

How do you know for sure the fluid is worn? The only definite way to find out is to conduct used fluid analysis. However, fluid that smells burnt or appears dirty is likely due for a change. It’s best practice to change the fluid before the frictional properties are depleted and you experience poor shifting. Those poor shifts can cause the clutches to wear more rapidly and lead to bigger issues that need mechanical repairs.

Be aware of “adaptive” transmissions

One interesting note affects newer vehicles equipped with adaptive transmissions. These units “learn” your driving habits and the characteristics of the fluid to adjust shifts accordingly. As the fluid loses its frictional properties, the computer compensates and adjusts transmission performance.

** If you’ve recently changed your fluid, the computer may still operate as if old fluid is installed, causing poor shift quality. In these cases, keep driving and eventually the computer will “relearn” your driving habits and the behavior of the new fluid and adjust accordingly. The problem was significant enough on some 2012-2013 Ford F-150s to cause Ford to issue a technical service bulletin (TSB 13-1-10).

What do “frictional properties” look like?

We know what good, crisp shifts feel like. Can we dive in even further and see what they look like?

We can, and they appear as a flat, boring line on a graph. The dark blue line represents the frictional properties of new AMSOIL Signature Series Synthetic Automatic Transmission Fluid. The light blue line shows the frictional properties of the same fluid after more than 180,000 miles in taxi cabs operating in the intense heat of Las Vegas.

As you can see, the lines are extremely close, with no abrupt spikes or dips. This means, after 180,000 miles of severe service, the fluid continued to deliver crisp, confident shifts.

Granted, it’s not exciting to look at – unless you love driving and want to protect your transmission.

Cold weather can reduce shift quality

When the temperature drops, transmission fluids with poor cold-flow properties can thicken and cause elongated and hard shifts until the fluid has warmed up enough to flow properly. Switching to a high-quality synthetic transmission fluid will help. Synthetics don’t contain waxes, as conventional fluids do, meaning they remain fluid at lower temperatures for improved shifts during cold weather.

The best transmission fluid available won’t fix a broken transmission. But using high-quality synthetic fluid can help improve shift quality and maximize transmission life.
