Clamping belt/disc sander to work bench
If your belt/disc sander is to be used as a portable
tool, it is recommended you fasten it permanently to
a mounting board that can easily be clamped to a
workbench or other stable surface.
The mounting board should be of sufficient size to
avoid tipping while belt/disc sander is in use. Any
good grade plywood or chipboard with a 3/4 in. (19
mm) thickness is recommended.
• Mark holes on board where belt/disc sander is to
be mounted using holes in the base as a template
for hole pattern.
• Follow last three steps in section Mounting Belt/
Disc Sander to Workbench.
If lag bolts are used, make sure they are long enough
to go through holes in belt/disc sander base and
material the belt/ disc sander is being mounted to.
If machine bolts are used, make sure bolts are long
enough to go through holes in belt/disc sander, the
material being mounted to, and the lock washers and
hex nuts.

ed with the grain to prevent them splitting. Impor-
tant. If the grinding wheel or the grinding/sanding
belt becomes jammed during operation, please re-
move the workpiece until the tool reaches its top
speed again.
