Rotating the Gear Case (Fig. C)
To improve user comfort, the gear case will rotate 90° for
cutting operations.
1. Remove the four corner screws attaching the gear case
to motor housing.
2. Without separating the gear case from motor housing,
rotate the gear case head to desired position.
nOTE: If the gear case and motor housing become
separated by more than 1/8" (3.17 mm), the tool must be
serviced and reassembled by a D
Failure to have the tool serviced may lead to motor and
bearing failure.
3. Reinstall screws to attach the gear case to the
motor housing. Tighten screws to 12.5 in.-lbs. torque.
Overtightening could cause screws to strip.
Guards
CAUTION: Guards must be used with all grinding
wheels, cutting wheels, sanding flap discs, wire brushes,
and wire wheels. The tool may be used without a guard
only when sanding with conventional sanding discs. Refer to
the Accessories Chart to see guards provided with the unit.
Some applications may require purchasing the correct guard
from your local dealer or authorized service center.
nOTE: Edge grinding and cutting can be performed with
Type 27 wheels designed and specified for this purpose;
6.35 mm thick wheels are designed for surface grinding
while thinner Type 27 wheels need to be examined for
the manufacturer's label to see if they can be used for
surface grinding or only edge grinding/cutting. A Type 1
guard must be used for any wheel where surface grinding
is forbidden. Cutting can also be performed by using a
Type 41 wheel and a Type 1 guard.
nOTE: Refer to the Accessories Chart to select the proper
guard/accessory combination.
Adjusting and Mounting Guard (Fig. D)
