5. To remove the wheel, grasp and turn while depressing the spindle
lock button.
USING CUTTING WHEELS
WARNING: Do not use edge grinding/cutting wheels for
surface grinding applications because these wheels are not
designed for side pressures encountered with surface grinding.
Wheel breakage and injury may result.
1. Allow tool to reach full speed before touching tool to work
surface.
2. Apply minimum pressure to work surface, allowing tool to operate
at high speed. Cutting rate is greatest when the tool operates at
high speed.
3. Once a cut is begun and a notch is established in the workpiece,
do not change the angle of the cut. Changing the angle will cause
the wheel to bend and may cause wheel breakage.
4. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury,
depress the lock-off button and remove battery pack before
making any adjustments or removing/installing attachments or
accessories.
An accidental start-up can cause injury.
Cleaning
WARNING:
Blow dirt and dust out of all air vents with clean, dry air
at least once a week. To minimize the risk of eye injury, always wear
ANSI Z87.1 approved eye protection when performing this.
WARNING:
Never use solvents or other harsh chemicals for cleaning
the non-metallic parts of the tool. These chemicals may weaken the
plastic materials used in these parts. Use a cloth dampened only with
be unable to rotate the guard by hand when the latch is in closed
position. Do not operate grinder with a loose guard or clamp lever
in open position.
5. To remove the guard, open the guard latch, rotate the guard so
that the lugs and slots are aligned and pull up on the guard.
NOTE:
The guard is pre-adjusted to the
O
dia met er of the gear case hub at the factory. If,
after a period of time, the guard becomes
loose, tighten the adjusting screw (O) with the
clamp lever in the closed position with guard
installed on the tool.
CAUTION:
To reduce the risk of damage to
the tool, do not tighten adjusting screw with
clamp lever in open position. Undetectable damage to guard or
mounting hub may result.
MOUNTING CUTTING WHEELS
CAUTION:
Matching diameter backing flange and threaded clamp
nut (included with the tool) must be used for cutting wheels.
1. Place the unthreaded backing flange on spindle with the raised
section (pilot) facing up. The raised section (pilot) on the backing
flange will be against the wheel when the wheel is installed. Be
sure the backing flange recess is seated onto the flats of the
spindle by pushing and twisting the flange before placing the
wheel.
2. Place the wheel on the backing flange, centering the wheel on the
raised section (pilot).
3. Install the threaded clamp nut with the raised section (pilot) facing
away from the wheel.
4. Depress the spindle lock button and tighten clamp nut with a
wrench.
