4. Close paper clamp by returning the clamp lever
to its original position. Press down on the sander
to mold the sandpaper to the base.
5. Wrap the sandpaper around the sanding pad.
Release the clamp lever on the opposite side of
the tool. Insert the loose end of the sandpaper
under paper clamp, pulling the sandpaper tight
against pad.
6. Close paper clamp by returning the clamp lever
to its original position.
7. Multiple sheets of sandpaper can be installed at
one time for convenience.
Paper Punch
A paper punch template has been supplied with the
sander for aligning and punching holes in sandpa-
per. The punched holes must align with the holes
in the sandering pad.
1. Install sandpaper on the sander.
2. Align sandering pad over the paper punch.
3. Push down on sander.
Attaching The Dust Bag
The dust bag provides a dust collection system for
the sander. Sanding dust is drawn up through the
holes of the sanding pad and collected in the dust
bag during sanding. To attach the dust bag:
1. Unplug the sander.
2. Line up the “unlock”
symbol on the dust
bag with the arrow
on the dust collec-
tion port and slide
the bag assembly
onto the port. To
lock in place, rotate
the bag until the ar-
row on the port aligns with the “lock” symbol on
the bag.
WARNING
When sander is not con-
nected to vacuum, always reinstall dust bag
assembly back onto sander. Fail ure to do so
could cause sanding dust or foreign objects to
be thrown into your face or eyes which could
result in possible serious injury.
Attaching the Sander to a Vacuum
To attach the dust collection system of the sander
to a vacuum:
1. Unplug the sander.
2. Remove the dust bag from the sander.
3. Attach vacuum hose to blower exhaust.
NOTE: Smaller vacuum hoses fi t inside blower
exhaust. Larger vacuum hoses fi t outside blower
exhaust.
OPERATION
Starting and Stopping the Tool
To start the sander, switch ON/OFF Switch to ON.
To stop sander, switch ON/OFF Switch to OFF.
WARNING
Finish sanding can produce
clouds of fi ne dust that could ignite in the
presence of sparks or open fl ame. Always
wear a suitable dust mask or respirator and
use your sander in a well-ventilated area.
WARNING
To reduce the risk of injury,
inspect for and remove all raised nails and
fasteners from workpiece before sanding.
Striking a fastener while sanding could cause
loss of control.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side shields.
WARNING
To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
General Sanding
When using sanders, remember:
• Varying pressure applied to the sander will affect
its speed. A light pressure is recommended for fi ne
work, moderate pressure for rough work. Excessive
pressure does not allow the pad to move enough.
• Keep sanding pad fl at on the workpiece. Tipping
the sander or using the edges of the pad may
produce an uneven fi nish, and reduce pad life.
• Keep sander moving in broad even strokes across
the workpiece. Sanding in one spot too long can
cause gouging and uneven results.
1. To prevent rough action due to starting under
load, turn ON/OFF Switch ON before applying
sander to workpiece.
2. Work in slow, overlapping strokes parallel to
grain. This sander is designed for even weight
distribution. Excessive pressure may damage
workpiece and motor as well as cause premature
sandpaper wear.
3. Repeat operation using successively fi ner grits
of sandpaper until desired fi nish is obtained.
Example: 60 Coarse, 100 Medium, 150 Fine.
WARNING
Properly secure workpiece
before sanding. Unsecured work could be
thrown towards the operator causing injury.
WARNING
Do not wear loose clothing
or jewelry when operating sander. They could
get caught in moving parts causing serious
injury. Keep head away from sander and
sanding area. Hair could be drawn into sander
causing serious injury.
Removing Paint or Varnish
1. When removing several layers of paint or var-
nish, remove as much as possible with a paint
solvent or varnish remover.
2. Scrape away the residue with a putty knife or
other scraping tool and allow the surface to cool
and dry before applying sander to the workpiece.
WARNING
To reduce the risk of fi re
and explosion, paint solvents and varnish re-
movers must be removed from the workpiece
and the workpiece must be completely dry
before sanding.
3. Select a coarse grit sandpaper disc to help pre-
vent the sandpaper from clogging.
4. Keep the sander moving over new areas to avoid
heating and softening the old coating (paint or
varnish).
5. Work in wide, overlapping strokes to produce a
uniform fi nish.
6. As the workpiece begins to show through the old
coating, switch to a medium grit sandpaper disc
to avoid scratching the surface of the workpiece.
Gradually switch to a fi ne grit sandpaper until you
achieve the desired fi nish.
For more effi cient operation, empty the dust bag
when it is no more than half full. This will permit the
air to fl ow through the bag better. Always empty and
clean the dust bag thoroughly upon completion of
a sanding operation and before storing the sander.
To empty the dust bag:
1. Unplug the sander.
2. Remove the dust bag from the sander.
3. Shake out the dust.
4. Reattach the dust bag to the sander.
WARNING
Collected sanding dust
from sanding surface coatings such as polyu-
rethanes, linseed oil, etc. can self-ignite in
the sander dust bag or elsewhere and cause
fi re. To reduce the risk of fi re always empty
the dust bag frequently (10-15 minutes) while
sanding and never store or leave a sander
without totally emptying its dust bag. Also
follow the recommendations of the coatings
manufacturers.

recommended accessories. Others may be
hazardous.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the
general condition of your tool. Inspect guards,
switches, tool cord set and extension cord for
damage. Check for loose screws, misalignment,
binding of moving parts, improper mounting, bro-
ken parts and any other condition that may affect
its safe operation. If abnormal noise or vibration
occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use a
damaged tool. Tag damaged tools “DO NOT USE”
until repaired (see “Repairs”).
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears, spin-
dles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electrical
operation
WARNING
To reduce the risk of injury,
electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid
to fl ow inside the tool.
MAINTENANCE
WARNING
To reduce the risk of injury,
always unplug your tool before performing
any maintenance. Never disassemble the tool
or try to do any rewiring on the tool’s electrical
system. Contact a MILWAUKEE service facility
for ALL repairs.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your
tool since certain cleaning agents and solvents
are harmful to plastics and other insulated parts.
Some of these include: gasoline, turpentine, lacquer
thinner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
