Removing the clutch from the chainsaw isn't difficult, but does require a few setup steps.

The clutch is screwed to the chainsaw motor shaft and can be unscrewed, however since rotating the clutch also spins the motor shaft we'll need to stop the motor from moving. The easiest way to do this is by arresting the engine piston, which will stop the engine shaft from spinning.

The easiest way to gain access to the piston without taking the entire engine apart is through the spark plug. The spark plug for this chainsaw was located under the air filter cover. Find and unplug the spark plug cap and gently unscrew the spark plug, use care when removing spark plugs as the porcelain insulator of the spark plug is fragile and can shatter if knocked or torqued too tight.

Once the spark plug is removed you can peer inside the opening and see the engine piston. Grab the clutch and rotate, you should be able to see the piston rise and fall (it's dark in there, so make sure you've got a flashlight). Rotate the clutch until the piston is all the way at the bottom.
