NOTE: Make sure all parts are in place as il-
lustrated, and the blade is sandwiched be-
tween the dust cup and the retaining washer.
There should be no space between the blade
and the dust cup or the retaining washer.
S
Align hole in the dust cup with the hole in the
side of the gearbox by rotating the blade.

This will keep the shaft from turning while
tightening the blade nut.
Hex Wrench
S Tighten the blade nut firmly with a wrench
while holding hex wrench in position.
S Remove the hex wrench.

against the shield, or appears to be uneven,
the blade is not centered, and you must rein-

NOTE: To remove blade, insert hex wrench
into aligned holes. Un-thread nut and remove
parts. Be sure to store parts and instructions
for future use.
