Figure G -
While depressing the spindle lock
button, thread the threaded clamp nut (13) on
spindle.
•
Figure H -
If the wheel you are installing is
more than 1/8
inch (3mm) thick
, place the threaded clamp nut on the spindle
so that the raised section (pilot)
fits into the center of the
wheel.
•
Figure I -
If the wheel you are installing is
1/8 inch (3mm)
thick or less
, place the threaded clamp nut on the spindle so
that the raised section (pilot)
is not against the wheel.
4. While depressing the spindle lock button (6), tighten the
threaded clamp nut with included wrench.
5. To remove the wheel, depress the spindle lock button and
loosen the threaded clamp nut with included wrench.
NOTE:
If the wheel spins after the threaded clamp nut is tightened, check the orientation
of the threaded clamp nut. If a thin wheel is installed with the pilot on the clamp nut against
the wheel, it will spin because the height of the pilot prevents the clamp nut from holding
the wheel.
SURFACE GRINDING WITH GRINDING WHEELS
1. Allow the tool to reach full speed before touching the tool to the work surface.
2. Apply minimum pressure to the work surface, allowing the tool to operate at high
speed. Grinding rate is greatest when the tool operates at high speed.
3.
Figure J -
Maintain a 20˚ to 30˚ angle between the tool and work
surface.
4. Continuously move the tool in a forward and back motion to avoid
creating gouges in the work surface.
5. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before laying it down.
EDGE GRINDING WITH GRINDING WHEELS
CAUTION:
Wheels used for edge grinding may break or kick back if they bend or twist
while the tool is being used to do cut-off work. To reduce the risk of serious injury, limit
the use of these wheels with a standard Type 27 guard to shallow cutting and notching
(less than 1/2 inch (13mm) in depth). The open side of the guard must be positioned
away from the operator.
For deeper cutting with a Type 1 cut-off wheel, use a closed
Type 1 guard.
