Spark Plug Replacement On A Chainsaw
This blog is a step-by-step instruction on how to replace spark plugs on chainsaws. The most common reason for replacing the spark plug is when the chainsaw won’t start or runs poorly and testing the spark plug proves it is defective.
Before you replace the spark plug in your chainsaw, you need to first make sure the engine has cooled and that the on/off switch is in the off position.
Step 1: Now unthread the knobs securing the air filter cover and pull the cover off.
Step 2: Remove the wire and boot from the spark plug.
Step 3: Use the provided wrench to help loosen the old spark plug then unthread.
Step 4: Before you install the new spark plug, you need to confirm that the spark gap is at manufacturer’s specifications.
Step 5: Now thread the plug into the cylinder and be careful not to strip the threads by over tightening.
Step 6: Attach the wire and boot to the new spark plug. Realign the cover and rethread the knob to secure. Replace the wrench in the handle base and turn the on/off switch to the on position.
Now you chainsaw should be ready for use.
