accessories. Refer to chart at the end of this section
for information on choosing the correct accessories.
NOTE: Edge grinding can be performed with
Type 27 wheels designed and specified for
this purpose.
WARNING: Accessories must be rated

the tool warning label. Wheels and other
accessories running over rated accessory
speed may burst and cause injury.
Threaded accessories must have a M14
hub. Every unthreaded accessory must
have a 22 mm arbor hole. If it does not,
it may have been designed for a circular
saw and should not be used. Use only
the accessories shown in the chart at the

must be above listed minimum wheel
speed as shown on tool nameplate.

MOUNTING AND REMOVING ONE-TOUCH GUARD (FIG. 3)
NOTE: If your grinder is supplied with a keyless
One-Touch guard, ensure the screw, lever,
and spring are fitted correctly before mounting
the guard.
1. Press the guard release lever (J).
2. While holding the guard release lever open,
align the lugs (M) on the guard with the slots (N)
on the gear case.
3. Keeping the guard release lever open, push the
guard down until the lugs engage then rotate
them into the groove on the gear case hub.
Release the guard release lever.
4. With the spindle facing the operator, rotate
the guard clockwise into the desired working
position. The guard body should be positioned
between the spindle and the operator to
provide maximum operator protection.
5. For easy adjustment, the guard can be rotated
in the clockwise direction. The guards design
allows the guard to be rotated and adjusted
by turning the guard in a clockwise, single
action motion. The lever does not need to
be depressed to turn the guard. The lever is
only used for removal of the guard. The guard
can be repositioned the opposite direction by
depressing the guard release lever. NOTE: The
guard release lever should snap into one of the
alignment holes (O) on the guard collar. This
ensures that the guard is secure.
6. To remove the guard, follow steps 1–3 of these
instructions in reverse.
