and/or pad could result in serious injury (or damage to
the tool orwheel).

grinding wheel, sanding flap disc, wire brush or
wire wheel applications after sanding applications
arecomplete.

Removing Guard (Fig. B)
To remove the guard, open the guard latch, rotate the guard
so that the lugs on the guard are aligned with the slots on
the gear case cover, and pull the guard away from the gear
casecover.
NOTE: The guard is pre-adjusted to the diameter of the gear
case hub at the factory. If, after a period of time, the guard
becomes loose, tighten the adjusting screw 14 with latch
in the closed position and guard installed on thetool.

CAUTION: Do not tighten the adjusting screw with
the latch in the open position. Undetectable damage
to the guard or the mounting hub may result. If the
guard cannot be tightened by the guard latch, do not
use the tool and take the tool and guard to a service
center to repair or replace theguard.
