Emptying the Dust Bag
Empty the dust bag when it is about 3/4
full.
1.
To empty the dust bag, remove the dust
bag from the sander.
APPLICATIONS
Finishing Wood
To level a rough surface quickly, use a
coarse grit belt. Firmly hold the sander at
an angle to the grain, moving it with the
grain (Fig. 3). Work the entire surface with
overlapping strokes.
Fig. 3
For a very fine surface, change belts two
or three times, using a finer grit belt each
time. Hold the sander parallel to the grain
and work the entire surface with each grit
(Fig. 4). Move with the grain to remove
scratches left by the coarser belts. Always
finish your work by sanding with the grain.

Be careful not to run off the end of the wood;
this will round the edge. Always keep the
sander flat against the work surface.
Sanding Doors and Trim
When sanding doors, trim, and other mill-
work, be careful not to sand the cross
grain at the joints where the direction of
the grain changes.
2.
Unzip the zipper and shake the bag over
a wastebasket.
3.
Occasionally, slip the bag off of the wire
frame and turn it inside out. Brush dust
from the lining with a soft brush to al-
low the bag to "breathe" better.
Finishing Metal, Plastics and Stone
(Fig. 5)
Fig. 5
Use a sweeping circular movement across
the entire surface, overlapping strokes for
an even finish. For a fine finish, change
belts two or three times, using a finer grit
each time. Do not use oil or other coolants;
the belt will throw the liquid and contami-
nate the tool.
Removing Paint or Varnish
When removing several layers of paint or
varnish, remove as much as possible with
a pint solvent or varnish remover. Scrape
the residue away and allow the surface to
dry thoroughly before sanding.
Select a coarse grit, open coat belt to pre-
vent clogging. Use short backward strokes,
lifting the sander quickly at the end of each
stroke to avoid burning the coating and
clogging the belt. Start each stroke in a
new area. As the base begins to show
through the coating, switch to a medium
grit to avoid scratching the surface of the
base.

MAINTENANCE

WARNING!
To reduce the risk of injury, al-
ways 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.
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, broken
parts and any other condition that may af-
fect its safe operation. If abnormal noise
or vibration occurs, turn the tool off imme-
diately 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 necessary 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, spindles, bearings, housing,
etc.)
Electrical inspection (switch, cord,
armature, etc.)
Testing to assure proper mechanical
and electrical operation
Vacuum System
Vacuum system failure may occur when
the sander is clogged with dust. To re-
move the dust, remove the dust bag from
the sander. Force air into the opening where
the bag was attached. Air can also be
forced into the opening behind the rear
roller underneath the sander. If the vacuum
system still fails to work, it may be clogged
with a foreign object. Should this happen,
return the entire sander to a MILWAUKEE
service facility for repair. Do not disas-
semble the sander.
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 clean-
ing agents and solvents are harmful to plas-
tics and other insulated parts. Some of
these include: gasoline, turpentine, lacquer
thinner, paint thinner, chlorinated cleaning
solvents, ammonia and household deter-
gents containing ammonia. Never use flam-
mable or combustible solvents around
tools.
WARNING!
To reduce the risk of injury, elec-
tric shock and damage to the tool,
never immerse your tool in liquid
or allow a liquid to flow inside the
tool.
Repairs
If your tool is damaged, return the entire
tool to the nearest service center listed on
the back cover of this operator's manual.
