BLADE REPLACEMENT

WARNING:
The blade will continue to
spin after the engine stops or after the throttle
trigger has been released. To avoid serious
injury, make sure the blade has stopped
coasting and disconnect the spark plug before
performing work on the blade.
WARNING:
when handling or performing maintenance on
the blade to avoid injury. The blade is sharp and
can cut you even when it is not moving.
1. To remove the blade, align hole in the dust
cup with the hole in the side of the gear-

holes. This will keep the shaft from turn-
ing while loosening the blade nut.
