WARNING: For your own safety, read all of the
instructions and precautions before operating tool.
CAUTION: Always follow proper operating procedures
as defined in this manual even if you are familiar with
use of this or similar tools. Remember that being care-
less for even a fraction of a second can result in severe
personal injury.
BE PREPARED FOR JOB
• Wear proper apparel. Do not wear loose clothing,
gloves, neckties, rings, bracelets or other jewelry
which may get caught in moving parts of machine.
• Wear protective hair covering to contain long hair.
• Wear safety shoes with non-slip soles.
• Wear safety glasses complying with United States
ANSI Z87.1. Everyday glasses have only impact
resistant lenses. They are NOT safety glasses.
• Wear face mask or dust mask if operation is dusty.
• Be alert and think clearly. Never operate power tools
when tired, intoxicated or when taking medications
that cause drowsiness.
PREPARE WORK AREA FOR JOB
• Keep work area clean. Cluttered work areas invite
accidents.
• Do not use power tools in dangerous environments.
Do not use power tools in damp or wet locations. Do
not expose power tools to rain.
• Work area should be properly lighted.
• Proper electrical receptacle should be available for
tool. Three prong plug should be plugged directly
into properly grounded, three-prong receptacle.
• Extension cords should have a grounding prong and
the three wires of the extension cord should be of
the correct gauge.
• Keep visitors at a safe distance from work area.
• Keep children out of workplace. Make workshop
childproof. Use padlocks, master switches or remove
switch keys to prevent any unintentional use of
power tools.
TOOL SHOULD BE MAINTAINED
• Always unplug tool prior to inspection.
• Consult manual for specific maintaining and adjust-
ing procedures.
• Keep tool lubricated and clean for safest operation.
• Remove adjusting tools. Form habit of checking to
see that adjusting tools are removed before switch-
ing machine on.
• Keep all parts in working order. Check to determine
that the guard or other parts will operate properly
and perform their intended function.
• Check for damaged parts. Check for alignment of
moving parts, binding, breakage, mounting and any
other condition that may affect a tool's operation.
• A guard or other part that is damaged should be
properly repaired or replaced. Do not perform
makeshift repairs. (Use parts list provided to order
replacement parts.)
KNOW HOW TO USE TOOL
• Use right tool for job. Do not force tool or attachment
to do a job for which it was not designed.
• Disconnect tool when changing belt or abrasive disc.
• Avoid accidental start-up. Make sure that the switch
is in the "off" position before plugging in.
• Do not force tool. It will work most efficiently at the
rate for which it was designed.
• Keep hands away from moving parts and sanding
surfaces.
• Never leave tool running unattended. Turn the power off
and do not leave tool until it comes to a complete stop.
• Do not overreach. Keep proper footing and balance.
• Never stand on tool. Serious injury could occur if tool
is tipped or if belt or disc are unintentionally contacted.
• Know your tool. Learn the tool's operation, applica-
tion and specific limitations.

• Use recommended accessories (refer to page 13).
Use of improper accessories may cause risk of
injury to persons.
• Handle workpiece correctly. Protect hands from pos-
sible injury.
• Turn machine off if it jams. Belt jams when it digs too
deeply into workpiece. (Motor force keeps it stuck in
the work.)
• Support workpiece with miter gauge, belt platen,
work stop or work table.
• Maintain 1/16"maximum clearance between table and
sanding belt or disc.
CAUTION: Think safety! Safety is a combination of
operator common sense and alertness at all times

• Additional abrasive discs are available (see
Recommended Accessories, page 13).
• Replace disc table and tighten knobs.
ABRASIVE DISC FINISHING
Refer to Figure 14.
• Abrasive disc sanding is well suited for finishing
small flat surfaces and convex edges.
• Move the workpiece across the down side (right) of
the abrasive disc. The abrasive disc moves fastest
and removes more material at the outer edge.
• For accuracy, use the miter gauge.
Figure 14 - Abrasive Disc Finishing
USING MITER GAUGE
• The miter gauge is used only on the disc table. Use
the miter gauge for securing work and holding the
proper angle while disc sanding.
• Adjust the angle by repositioning the miter gauge
scale and locking it into place with knob. Check the
accuracy of the miter gauge. Use a combination
square to adjust the miter gauge square to the disc.
• Indicator should be at zero. Loosen screw and repo-
sition indicator if necessary.
WARNING: Make certain that unit is disconnected
from power source before attempting to service or
remove any component.
CLEANING
Keep machine and workshop clean. Do not allow saw-
dust to accumulate on the tool. Keep wheels clean. Dirt
on wheels will cause poor tracking and belt slippage.
Operate tool with dust collector to keep dust from accu-
mulating.
WARNING: After sanding wood or nonmetallic materi-
al, always clean area of sawdust before grinding metal.
Sparks could ignite debris and cause a fire.
Be certain motor is kept clean and is frequently vacu-
umed free of dust.
Use soap and water to clean painted parts, rubber
parts and plastic guards.
LUBRICATION
The shielded ball bearings in this sander are perma-
nently lubricated at the factory. They require no further
lubrication.
• When operation seems stiff, a light coat of automo-
bile-type wax applied to the belt table and disc table
will make it easier to feed the work while finishing.
• Do not apply wax to the belt platen. Belt could pick
up wax and deposit it on wheels causing belt to slip.
