MOUNTING AND REMOVING (TYPE 27 & TYPE 1)
ONE-TOUCH™ GUARD (FIG. 4, 5)
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 (K).
2. While holding the guard release lever open,
align the lugs (L) on the guard with the
slots on the gear case (M).
3. Keeping the guard release lever open, push the guard down until
the guard lugs engage and rotate them in 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. NOTE:
The guard release lever should snap into
one of the alignment holes (N) on the guard collar. This insures
that the guard is secure. The guard can be repositioned the
opposite direction by depressing the guard release lever.
6. To remove the guard, follow steps 1–3 of these instructions in
reverse.

wheels are designed for surface grinding while 1/8" (3.17 mm) wheels
