MANUALLY ADJUSTING SANDING BELT
TRACkING
See Figure 11, page 15.
This sander features an automatic tracking system designed
to keep the sanding belt centered. If edge sanding is desired,
manual adjustment of the belt will be necessary.
To manually adjust belt position:
 Connect the sander to power supply.
 Set the variable speed control dial to the lowest setting
(A).
 With sander positioned as shown, pull switch trigger.
NOTE: This position is for adjustments only. Sanding belt
should not be in contact with workpiece or any foreign
objects when making belt tracking adjustments.

MAINTENANCE

WARNING:
When servicing use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
WARNING:
Always wear eye protection marked to comply with
ANSI Z87.1. Failure to do so could result in objects
being thrown into your eyes resulting in possible
serious injury.
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. Chemicals can
damage, weaken or destroy plastic which may
result in serious personal injury.
 Slowly turn the tracking screw clockwise until the sanding
belt is positioned at the edge of the platen. Do not allow
the sanding belt to extend past the edge of the platen.
WARNING:
Keep hands and fingers away from moving
sanding belt. Any part of body coming in contact
with moving sanding belt could result in serious
injury. Do not wear loose clothing or jewelry when
operating sander. They could get caught in moving
parts and foreign objects could get thrown from
sander causing injury.
 When edge sanding is completed, return the belt to the
default centered position by turn the tracking screw
counterclockwise until the belt is positioned correctly.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass
chips and grindings are highly abrasive to bearings, 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 sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrication
is required.
BRUSH REPLACEMENT
See Figure 12, page 15.
NOTE: This belt sander is equipped with externally
accessible brushes.
 Unplug the sander.
WARNING:
Failure to unplug the tool could result in accidental
starting causing possible serious injury.
 Remove brush caps (2) using a screwdriver.
 Remove brush assemblies (2).
