This angle grinder/cut-off tool is equipped

the best control and guard protection.

the battery pack, then thread the
auxiliary handle into the auxiliary-handle
socket and tighten the handle securely
by turning it clockwise.
The grinding wheel or cutting wheel (not

debris. Inspect the parts for damage.
Replace if needed.
4. Properly position the grinding or cutting
guard.
5. Place the backing ange on the spindle
and align it with the spindle, make sure
that the backing ange is positioned
so that the shape of the opening in the
ange corresponds with the shape at the
base of the spindle.
6. Place the grinding or cutting wheel on
the spindle and align it with the backing
ange. Always install the grinding wheel
with the depressed center against the
backing ange.

position the lock nut so that the raised,
small diameter portion of the lock nut
faces the hole in the grinding wheel (FIG.

surface faces the cutting wheel (FIG. 5).
8. Thread the lock nut onto the spindle.

lock nut clockwise using the wrench.
