Mounting Depressed Centre Grinding
Wheels
NOTE: The Type 27 guard supplied with grinder
MUST be used.
MOUNTING AND REMOVING HUBBED WHEELS (FIG. 1, 4)
Hubbed wheels install directly on the M14 threaded
spindle.
1. Thread the wheel on the spindle (d) by hand.
2. Depress the spindle lock button (c) and use a
wrench to tighten the hub of the wheel.
3. Reverse the above procedure to remove the
wheel.
NOTICE: 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 (FIG. 1, 4)
NOTE: The Type 27 guard supplied with grinder
MUST be used.
NOTE: Please refer to the Grinding and Cutting
Accessory Chart at the end of this section to
see other accessories that can be used with these
grinders.
1. Place the tool on a table, guard up.
2. Install the unthreaded backing flange (g) on
spindle (d) with the raised centre against the
wheel.
3. Place wheel (f) against the backing flange,
centreing the wheel on the raised centre of the
backing flange.
4. While depressing the spindle lock button (c),
thread the clamp nut (h) on spindle. If the
wheel you are installing is more than 1/8"
(3.17mm) thick, place the threaded clamp nut
on the spindle so that the raised centre fits into
the centre of the wheel. If the wheel you are
installing is 1/8" (3.17 mm) thick or less, place
the threaded clamp nut on the spindle so that
the raised centre is not against the wheel.
5. While depressing the spindle lock button (c),
tighten the clamp nut with a wrench.
6. To remove the wheel, depress the spindle lock
button and loosen the threaded clamp nut with
a wrench.
NOTE: If the wheel spins after the clamp nut is
tightened, check the orientation of the threaded
clamp nut. If a thin wheel is installed with the
raised centre on the clamp nut against the wheel,
it will spin because the height of the raised centre
prevents the clamp nut from holding the wheel.
Mounting Wire Brushes and Wire
Wheels (fi g. 1)
Wire cup brushes or wire wheels install directly on
the threaded spindle without the use of flanges.
Use only wire brushes or wheels provided with a
M14 threaded hub. These accessories are available
at extra cost from your local dealer or authorised
service centre.
NOTE: The Type 27 guard is required when using
wire brushes and wheels.
CAUTION: To reduce the risk of
personal injury, wear work gloves
when handling wire brushes and
wheels. They can become sharp.
CAUTION: To reduce the risk
of damage to the tool, wheel
or brush must not touch guard
when mounted or while in use.
Undetectable damage could occur
to the accessory, causing wires to
fragment from accessory wheel or cup.
MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
1. Place the tool on a table, guard up.
2. Thread the wheel on the spindle by hand.
3. Depress spindle lock button (c) and use a
