Some grinding wheels must be replaced
before spark deflector or tool rest reach
their final adjustment. As diameter of a
grinding wheel is reduced, so is available
surface speed. Grinding under these condi-
tions can lead to faster abrasive loss and
poor grinding results. Always follow wheel
manufacturer's directions.
NEVER grind without tool rest in place and
properly positioned. "Free hand" grinding
or too large of a gap between wheel and tool
rest increases risk of kickback, which may
lead to serious injury.
Figure 16. Spark deflector gap.
The spark deflector prevents sparks from shower-
ing the top of the workpiece and the operator's
hands. As the wheel wears, adjust the spark
deflector closer to the grinding wheel to main-
tain a gap of
1
⁄
8
" –
1
⁄
4
" (see
Figure 16). If the gap
reaches
1
⁄
4
" and no additional adjustments can be
made, replace the grinding wheel.

6. Attach tool rest assemblies to grinder using
(2) M5-.8 x 50 carriage bolts, (2) 5mm fender
washers, (2) 5mm lock washers, and (2)
M5-.8 knobs (see
Figure 14).

The tool rest stabilizes the workpiece when grind-
ing. It must always be positioned correctly when
using the grinder, to avoid workpiece and possibly
operator's hands from being pulled into grinding
wheel.
As the grinding wheel wears, adjust the tool rest
closer to the grinding wheel to maintain a gap
of
1
⁄
16
" –
1
⁄
8
" (see
Figure 15). If the gap reaches
1
⁄
8
" and no additional adjustments can be made,
replace the grinding wheel.
