Accessories
It is important to choose the correct guards, backing pads
and flanges to use with grinder accessories.
Mounting guard (Fig. B and C)
1. Figure B: Open the guard latch (6), and align the lugs
on the guard (7) with the slots on the gear case cover (8).
2. Push the guard down until the guard lugs engage and
rotate freely in the groove on the gear case hub.
3. With the guard latch open, rotate the guard into the
desired working position. The guard body should be
positioned between the spindle and the operator to
provide maximum operator protection.
4. Figure C: Close the guard latch (6) to secure the
guard on the gear case. You should not be able to
rotate the guard by hand when the latch is closed. Do
not operate the grinder with a loose guard or the
guard latch 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.
Adjusting the guard (Fig. D)
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
(9) 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.
Caution! 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.
OPERATION
Switch
To start the grinder, push the slider switch (1) forward. For
continuous operation, push the slider switch forward and
push the front down until it locates in the lock position. To
turn the tool off, press the rear of the slider switch. Spring
action returns the switch to the off position.
Caution! Hold the side handle (4) and body of the tool
firmly to maintain control of the tool at start up and during
use and until the wheel or accessory stops rotating. Make
sure the wheel has come to a complete stop be fore laying
the tool down.
Caution! Allow the tool to reach full speed before
touching tool to the work surface. Lift the tool from the
work surface before turning the tool off.
Spindle lock
The spindle lock button (5) is provided to prevent the
spindle from rotating when installing or removing wheels.
Operate the spindle lock only when the tool is turned off
and the wheel has come to a complete stop.
Warning! Do not engage the spindle lock while the tool
is operating. Damage to the tool will result and attached
accessory may spin off possibly resulting in injury.
To engage the lock, depress the spindle lock button
shown in Fig. E and rotate the spindle until you are unable
to rotate the spindle further.
MOUNTING AND USING DEPRESSED
CENTER GRINDING WHEELS AND
SANDING FLAP DISCS
Mounting and Removing Hubbed Wheels
Warning! To prevent accidental operation, turn off
and unplug tool before performing the following
operations. Failure to do this could result in serious
personal injury.
Hubbed wheels install directly on the 5/8 in.-11 threaded
spindle.
1. Thread the wheel on the spindle by hand.
2. Depress the spindle lock button and use a wrench
(Fig. E) to tighten the hub of the wheel.
3. Reverse the above procedure to remove the wheel.
Caution! Failure to properly seat the wheel before
turning the tool on may result in damage to the tool or the
wheel.
Mounting Non-Hubbed wheels
Warning! To prevent accidental operation, turn off and
unplug tool before performing the following operations.
Failure to do this could result in serious personal injury.
1. Figure F: Install the unthreaded backing flange (10)
on spindle (11) with the raised section (pilot) against
the wheel.
2. Place wheel against the backing flange, centering the
wheel on the raised section (pilot) of the backing flange.
3. Figure G: While depressing the spindle lock button,
thread the threaded clamp nut (12) on spindle.
► Figure H: If the wheel you are installing is
more than 1/8 inch (3mm) thick, place the
threaded clamp nut on the spindle so that the
raised section (pilot) fits into the center of the
wheel.
► Figure I: If the wheel you are installing is 1/8 inch
(3mm) thick or less, place the threaded clamp
nut on the spindle so that the raised section (pilot)
is not against the wheel.
