HELPFUL
TIPS
If the sanding belt slips or does not track while sanding,
you may be applying too much pressure. When this oc-
curs, remove the sander from the workpiece. If you prop-
erly adjust the belt tracking, the sanding belt will return
to its normal and correct position on the drive roller and
front roller.
Use a coarser sanding belt for heavy sanding, not heavy
pressure. The weight of the tool is sufficient to provide
adequate pressure at the correct location.
The front roller of the sander is not designed for contour
sanding. Sanding on the front roller could cause irregu-
larity in the sanding belt tracking
and damage to the
sander.

GENERAL
MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.

WARNING:
Do not at any time let brake fluids,
gasoline, petroleum-based
products, penetrating
oils, etc., come in contact with plastic parts. Chemi-
cals can damage, weaken or destroy plastic which
may result in serious personal injury.
Electric tools used on fiberglass material, wallboard,
spackling compounds,
or plaster are subject to accel-
erated wear and possible premature failure because the
fiberglass chips and grindings are highly abrasive to bear-
ings, brushes, commutators,
etc. Consequently, we do not
recommended
using this tool for extended work on these
types of materials. However, if you do work with any of
these materials, it is extremely important to clean the tool
using compressed air.
LUBRICATION
All of the bearings in this tool are lubricated with a suffi-
cient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts
should be replaced at a Sears Service Center.
