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: 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, push in locking le-
ver and hold.
2. Rotate blade nut until the locking lever
falls into one of the grooves in the dust

you are facing the nut.
5. Remove the blade nut, both washers,
and the blade from the blade shaft. Leave
the dustcup on the gearbox.

onto the threaded shaft extending from
the gearbox (blade must be between the
dust cup and the retaining washer). Make
sure the raised part of the retaining wash-
er is facing the gearbox, and the raised
