USING WIRE CUP BRUSHES AND WIRE WHEELS
(FIG. 15, 16)
Wire wheels and brushes can be used for removing rust, scale and
paint, and for smoothing irregular surfaces.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to work
surface, allowing the tool to operate
at high speed. Material removal rate is
greatest when the tool operates at high
speed.
3. Maintain a 5˚ to 10˚ angle between the tool and work surface for
wire cup brushes.
4. Maintain contact between the edge of the wheel and the work
surface with wire wheels.
5. Continuously move the tool in a forward and
backward motion to avoid creating gouges in
the work surface. Allowing the tool to rest on
the work surface without moving, or moving the
tool in a circular motion causes burning and
swirling marks on the work surface.
6. Remove the tool from the work surface before turning the tool off.
Allow the tool to stop rotating before setting it down.
CAUTION: Use extra care when working over an edge, as a
sudden sharp movement of grinder may be experienced.
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: Utilize the 1-11/16" (43 mm) diameter quick-change backing
flange (G1) when using Type 1 wheels.
WARNING: A closed, 2-sided cutting wheel guard is not included
with this tool and is re quired when using cutting wheels. Fail ure to use
proper flange and guard can re sult in injury resulting from wheel
FIG. 15
breakage and wheel contact. See page 10 for more information.
MOUNTING CLOSED (TYPE 1) GUARD (FIG. 17, 18)
1. Open the guard latch (M). Align the
5˚-10˚ lugs (K) on the guard with the slots
(L) on the gear case.
2. Push the guard down until the guard
lug engages and rotates freely in the
groove on the gear case hub.
3. Rotate guard (D) into desired working
position. The guard body should be
FIG. 16
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 (N) with guard latch (M) in the closed
position. Do not operate grinder with a loose guard or guard latch
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
(N) with the guard latch in the closed position.
