OPERATION
WARNING
To reduce the risk of injury, always
remove battery pack before chang
-
ing or removing accessories or making adjust-
ments. Only use accessories specifically recom
-
mended for this tool. Others may be hazardous.
To reduce the risk of injury, always wear safety
goggles or glasses with side shields.
Starting and Stopping the Tool
To
start
the sander, press the ON (I) button.
To
stop
sander, press the OFF (O) button.
Speed Dial
The speed dial allows the sander to operate at variable
speeds - from low speed (1) to high speed (6).
1.
To increase sanding disc speed, turn the dial to a
higher setting.
2.
To decrease sanding disc speed, turn the dial to a
lower setting.
WARNING
Finish sanding can produce clouds
of fine dust that could ignite in the
presence of sparks or open flame. Always wear a
suitable dust mask or respirator and use your
sander in a well-ventilated area.
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.
General Sanding with Random Orbit Sanders
When using random orbit sanders there are a few
things to keep in mind:
• Unlike most sanders, random orbit sanders should
be placed on the workpiece BEFORE the tool is
started. If the sander is started before it is placed on
the workpiece, the free floating pad may be spinning
at a speed that can cause scratches when it is finally
placed on workpiece.
• Unlike most sanders, random orbit sanders can be
moved across the workpiece in any direction (in the
case of wood, regardless of the direction of the grain).
• Varying pressure applied to the sander will affect its
rotating speed. A light pressure is recommended for
fine work, moderate pressure for rough work. Exces
-
sive pressure does not allow the pad to rotate enough.
• Keep sanding pad flat on the workpiece. Tipping the
sander or using the edges of the pad may produce
an uneven finish, 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.
• Check the workpiece frequently, random orbit sanders
work more aggressively than simple orbital sanders.
WARNING
Properly secure workpiece before
sanding. Unsecured work could be
thrown towards the operator causing injury.
Do not wear loose clothing or jewelry when op-
erating 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.
1. Place sander on the workpiece and turn on the
sander.
2. Keep the sanding disc flat against the workpiece,
keep the sander moving across the workpiece, and
use long, sweeping strokes.
3. Begin sanding with a coarse grit sandpaper and
gradually use finer and finer grits of sandpaper until
the desired finish is reached. For example when
using the sander on wood, begin with an 80 grit
followed by a 120 grit, then a 180 grit and so on.
Removing Paint or Varnish
1. When removing several layers of paint or varnish,
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 fire and explo
-
sion, paint solvents and varnish
removers must be removed from the workpiece
and the workpiece must be completely dry before
sanding.
3. Select a coarse grit sandpaper disc to help prevent
the sandpaper from clogging.
4. Keep the sander moving over new areas to avoid heat
-
ing and softening the old coating (paint or varnish).
5. Work in wide, overlapping strokes to produce a
uniform finish.
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 fine grit sandpaper until you
achieve the desired finish.
MAINTENANCE
WARNING
To reduce the risk of injury, always
unplug the charger and remove the
battery pack from the charger or tool before per
-
forming any maintenance. Never disassemble the
tool, battery pack or charger. Contact a MILWAUKEE
service facility for ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program.
Inspect your tool for issues such as undue noise,
misalignment or binding of moving parts, breakage of
parts, or any other condition that may affect the tool
operation. Return the tool, battery pack, and charger
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the tool,
battery pack and charger to a MILWAUKEE service
facility for inspection.
If the tool does not start or operate at full power with a
fully charged battery pack, clean the contacts on the
battery pack. If the tool still does not work properly,
return the tool, charger and battery pack, to a MIL-
WAUKEE service facility for repairs.
WARNING
To reduce the risk of personal in-
jury and damage, never immerse
your tool, battery pack or charger in liquid or allow
a liquid to flow inside them.
Cleaning
Clean dust and debris from vents. Keep handles clean,
dry and free of oil or grease. Use only mild soap and
a damp cloth to clean, 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 contain-
ing ammonia. Never use flammable or combustible
solvents around tools.
Repairs
For repairs, return the tool, battery pack and charger
to the nearest service center.
