guard by hand when the latch
M
is in closed position. If rotation is pos-
sible, tighten the adjusting screw (M)
with clamp lever in the 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 arrows are aligned and pull up on the guard.
NOTE: If, after a period of time, the guard becomes loose, tighten
the adjusting screw (M) with the clamp lever in the closed position.
CAUTION: Do not tighten adjusting screw with clamp lever in
open position. Undetectable damage to guard or mounting hub
may result.
MOUNTING CUTTING WHEELS
CAUTION: Turn off and unplug the tool before making any
adjustments or removing or installing attachments or
accessories. Before reconnecting the tool, turn the switch on
and off as previously described to ensure that the tool is off.
CAUTION: Matching diameter backing flange and threaded
clamp nut (included with 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.
2. Place the wheel on the quick-change 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.
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,
turn tool off and disconnect tool from power source before
making any adjustments or removing/installing attachments
or accessories. Before reconnecting the tool, depress and
release the trigger switch to ensure that the tool is off.
Cleaning
WARNING: Blowing dust and grit out of motor and switch actuator
using clean, dry compressed air is a necessary regular maintenance
procedure. Dust and grit containing metal particles often accumulate
on interior surfaces and could create an electrical shock or
electrocution if not frequently cleaned out. It is recommended that a
ground fault circuit interrupter (GFCI) is utilized to further protect the
user from electric shock resulting from the accumulation of conductive
particles. If the tool is deactivated by the GFCI, unplug the tool and
