DISASSEMBLING

Warning: Remove Spark plug cap from Spark plug to prevent accidental engine starting.

Note: Clutch can be easily removed with a cordless impact driver without locking Piston, because it is locked in a position due to the compressed air resistance in Cylinder.

Therefore, do not remove Spark plug, or the air in Cylinder cannot be compressed.
