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 (or
disconnect powerhead from power source)
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.

cup with the hole in the side of the gearbox
by rotating the blade.

holes. This will keep the shaft from turning
while loosening the blade nut.

The blade will continue
to spin after the engine stops or after the

WARNING:
Always replace a blade
that is bent, warped, cracked, broken, or
damaged in any other way. Never attempt to
straighten and reuse a damaged blade. Use
only specified replacement blade. Wear pro-
tective gloves when handling or performing
maintenance on the blade to help avoid injury.
S The blade is reversible. When the cutting
edge on one side becomes worn, turn the
