BLADE REPLACEMENT
WARNING:

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:
Wear protective gloves
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-
box by rotating the blade.

Insert a small screwdriver into aligned
holes. This will keep the shaft from turn-
ing while loosening the blade nut.

unit. Do this by planting feet firmly in a com-
fortable apart position.

body from left to right.

be sure to maintain your balance, and footing.

ous injury. Stop engine and blade before remov-
ing materials wrapped around blade or shaft.

aged in any other way. Never attempt to
