INSTALLATION
Grinder must be mounted on horizontal surface
The Craftsman grinder pedestal available at Sears retail or
catalog store is designed especially for your grinder. Use of
the pedestal will permit greater accessibility to your unit
for grinding, buffing and many other uses.
To mount your grinder to the pedestal, align slots in base
with corresponding holes in table of the pedestal. Use two
5/16 bolts 2 inches long with flat washers beneath the
heads. Tighten nuts until space between grinder base and
pedestal is 3/16 inch. See figure 5.
Using a second nut on each bolt; jam-tighten against the
first to prevent loosening by vibration.
A Craftsman workbench provides a good mounting for your
grinder, when drawer space is desired as well as surface
space.
To mount your grinder to the bench top use two 5/16
wood screws 2 inches long with flat washers beneath the
heads. Tighten screws until clearance between base and
surface of bench is 3/16 inch. See figure 5.
