On bench grinders, tool rests and spark guards
are adjustable to compensate
for wheel wear. They
must be reset when a
new wheel is installed or
after a wheel has been
worn or dressed.
The distance between
the spark guard and
the wheel should be
within 1/16”. The tool rest
should be slightly below
the center of the wheel
with 1/8” or less clearance
from the wheel. This prevents accidental
jamming between tool rest and the wheel.
When Done...
Unplug, clean and store the tool in a safe, dry
place after use.
Never lay the power tool down until the accessory
has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
