Mounting and Using Cutting
(Type 1) Wheels (Fig. 1)
Cutting wheels include diamond wheels and abrasive discs. Abrasive
cutting wheels for metal and concrete use are available. Diamond
blades for concrete cutting can also be used.
NOTE" All grinders that use Type 1 wheels use the quick-change
backing flange (G1).
_ WARNING: A closed, 2-sided cutting wheel guard is not included
with this tool and is required when using cutting wheels. Failure to use
proper flange and guard can result in injury resulting from wheel
breakage and wheel contact. See page 10 for more information.
MOUNTING CLOSED (TYPE 1) GUARD (FIG. 16, 17)
1. Open the guard latch (J). Align the lugs (K) on the guard with the
slots (L) on the gear case.
2. Push the guard down until the guard FIG.16
lug engages and rotates freely in the I J
groove on the gear case hub.
3. Rotate guard (D) into desired working
position. The guard body should be
positioned between the spindle and
the operator to provide maximum
operator protection.
4. Close the guard latch to secure the
guard on the gear case cover. You
should be unable to rotate the guard
by hand when the latch is in closed
position. If rotation is possible,
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) FIG.17
with the clamp lever in the closed position.
._CAUTION: Do not tighten adjusting screw M
with clamp lever inopen position. Undetectable
damage to guard or mounting hub may result.
MOUNTING CUTTING WHEELS
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 (FIG. 18)
i_ 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.
