Scrench (combination screwdriver/wrench)
Round file with a file guide
Flat file
Chain and bar oil
Degreaser or mild soap
A soft brush or air compressor
Clean rag
New spark plug and air filter (if needed)
Fuel mix (for 2-stroke gas chainsaws)

Daily Chainsaw Maintenance Checklist

Perform this after every use to avoid buildup and wear:

1. Clean the Exterior

Wipe down the chainsaw body using a damp cloth to remove dust, sap, and sawdust.

2. Inspect the Chain Tension

A loose chain can derail and cause injury.
A tight chain can overheat and wear out fast.
Test: The chain should snap back when pulled slightly from the bar. Adjust using the side tensioner screw.

3. Check Chain Sharpness

A dull chain produces fine sawdust instead of wood chips.
It also requires more pressure and causes fatigue.
Sharpen if needed (details below).

4. Top Up Chain and Bar Oil

Running your chainsaw without oil causes the chain and bar to overheat, warp, or break. Always refill before operation.

5. Clear Debris from Air Intake and Sprocket Area

Use a brush or air blower to clean the air vents, bar groove, and chain sprocket cover.

Weekly or Frequent Chainsaw Maintenance Tasks

For regular users, these tasks should be done every week or every 10 hours of use:

1. Sharpen the Chain

Use a round file and guide. Follow these tips:

File each cutting tooth the same number of strokes
Maintain the correct angle (usually 25° to 35°)
Don’t forget the rakers (depth gauges) – use a flat file and depth gauge tool

📝 Tip: Replace the chain if teeth are uneven, cracked, or severely worn.

2. Clean or Replace the Air Filter

Dirty air filters reduce engine efficiency. Here’s how to clean it:

Remove and tap gently to dislodge debris
Wash with soapy water if reusable (foam filters)
Dry completely before reinstalling
Replace if it’s paper-based and clogged or torn

3. Check the Spark Plug

Remove the plug with your scrench
Clean light deposits with a wire brush
Replace the spark plug if the tip is black or corroded
Set the correct gap using a feeler gauge (refer to your chainsaw manual)

4. Inspect and Clean the Guide Bar

Look for uneven wear or burrs on the edges
Use a flat file to smooth out any damage
Flip the bar regularly to ensure even wear
Clean the oil holes and chain groove

Monthly or Seasonal Chainsaw Maintenance (Deep Clean)

If you use your chainsaw heavily or are putting it in storage, perform the following:

1. Clean the Carburetor and Muffler

Remove the cover and gently clean the carburettor housing. Clean carbon buildup from the muffler and spark arrestor screen.

2. Inspect the Fuel Filter and Fuel Line

Replace the fuel filter if you see debris or sluggish fuel flow. Check hoses for cracks or leaks.

3. Lubricate the Clutch Drum and Bearings

Some chainsaws require periodic greasing. Check your model’s manual.

How to Store Your Chainsaw Properly

Whether it’s the off-season or just between jobs, storage matters:

Empty the fuel tank (or add a fuel stabilizer for long storage)
Remove the chain and bar, and clean them thoroughly
Apply oil to prevent rust
Store in a dry, shaded, and secure location
Use a case or blade guard for extra protection

Common Chainsaw Maintenance Mistakes to Avoid

Avoid these costly and dangerous habits:

Running without chain oil
Filing the chain unevenly
Forgetting to clean the air filter
Ignoring small leaks or cracks
Leaving old fuel in the tank
Using the wrong fuel-to-oil mix
