Read and understand all instructions. Failure to follow all instructions
listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
Keep your work area clean and well lit.
Cluttered benches and dark areas invite
accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the
dust or fumes.
Keep by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Double Insulated tools are equipped with
a polarized plug (one blade is wider than
the other.) This plug will fit in a polarized
outlet only one way. If the plug does not
fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified
electrician to install a polarized outlet. Do
not change the plug in any way. Double
Insulation eliminates the need for the
three wire grounded power cord and
grounded power supply system. Before
plugging in the tool, be certain the outlet
voltage supplied is within the voltage marked
on the nameplate. Do not use “AC only”
rated tools with a DC power supply.
Avoid body contact with grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased
risk of electric shock if your body is
grounded. If operating the power tool in
damp locations is unavoidable, a Ground
Fault Circuit Interrupter must be used to
supply the power to your tool. Electrician’s
rubber gloves and footwear will further
enhance your personal safety.
Don't expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the
cord to carry the tools or pull the plug
from an outlet. Keep cord away from
heat, oil, sharp edges or moving parts.
Replace damaged cords immediately.
Damaged cords increase the risk of electric
shock.
When operating a power tool outside, use
an outdoor extension cord marked "W-A"
or "W." These cords are rated for outdoor
use and reduce the risk of electric shock.
Refer to “Recommended sizes of Extension
Cords” in the Accessory section of this
manual.
Personal Safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose
clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry,
or long hair can be caught in moving parts.
Keep handles dry, clean and free from oil
and grease.
Avoid accidental starting. Be sure switch
is “OFF” before plugging in. Carrying tools
with your finger on the switch or plugging in
tools that have the switch “ON” invites
accidents.
Remove adjusting keys or wrenches
before turning the tool “ON”. A wrench or
a key that is left attached to a rotating part
of the tool may result in personal injury.
Do not overreach. Keep proper footing
and balance at all times. Proper footing
and balance enables better control of the
tool in unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions.

Safety Rules for Orbital Sanders
Unplug the sander before changing
accessories. Accidental start-ups may
occur if sander is plugged in while changing
an accessory.
If your tool is equipped with a dust bag,
empty it frequently and after completion
of sanding. Be extremely careful of dust
disposal, materials in fine particle form may
be explosive. Do not throw sanding dust on
an open fire. Spontaneous combustion, may
in time, result from mixture of oil or water
with dust particles.
Use special precautions when sanding
chemically pressure treated lumber, paint
that may be lead based, or any other
materials that may contain carcinogens. A
suitable breathing respirator and protective
clothing must be worn by all persons
entering the work area. Work area should be
sealed by plastic sheeting and persons not
protected should be kept out until work area
is thoroughly cleaned.
Do not wet sand with this sander. Liquids
entering the motor housing is an electrical
shock hazard.
Do not use sandpaper intended for larger
sanding pads. Larger sandpaper will extend
beyond the sanding pad causing snagging,
tearing of the paper or kick-back. Extra
paper extending beyond the sanding pad
can also cause serious lacerations.
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement
and other masonry products, and
• Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.
Tool Use and Care
Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
Do not force tool. Use the correct tool for
your application. The correct tool will do
the job better and safer at the rate for which
it is designed.
Do not use tool if switch does not turn it
“ON” or “OFF”. Any tool that cannot be
controlled with the switch is dangerous and
must be repaired.
Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally. Store
idle tools out of reach of children and
other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools, with sharp cutting edges are less likely
to bind and are easier to control. Any
alteration or modification is a misuse and
may result in a dangerous condition.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools. Develop
a periodic maintenance schedule for your
tool.
Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be
suitable for one tool,
may become hazardous
when used on another tool.

BACKING PAD INSTALLATION
Your BOSCH corner/detail sander is
equipped with a hook-and-loop rubber
backing pad which may be removed and
attached without the need of additional
tools. To remove, push the pad lock button
to the right as far as possible and pull the
backing pad free of the sander. (For
maximum use of abrasive, rotate pad 120
degrees when tip of abrasive becomes
worn.) To replace, push backing pad back
into place, and secure with the pad lock
button.
When sanding in extremely tight areas, such
as louvered panels, optional extension
plates are available.
Your Bosch sander uses hook-and-loop
backed accessories, which firmly grip the
backing pad when applied with moderate
pressure. To change, merely peel off the old
accessory, remove dust from the backing
pad if necessary, and press the new
accessory in place. Be sure to align the
sanding sheet holes with the holes in the
backing pad to allow the dust extraction
system to function.
After considerable service the backing pad
surface will become worn, and the backing
pad must be replaced when it no longer
offers a firm grip. If you are experiencing
premature wearout of the backing pad
facing, decrease the amount of pressure you
are applying during operation of the tool.
DUST EXTRACTION
The integral dust port collects sanding dust
in a shop vacuum when fitted with the
optional Bosch Airsweep hose. However,
the sander may be operated without the
dust collection system if desired, as it will
not harm the tool. See your Bosch dealer
for optional Bosch Airsweep accessories.
"Tool Tips"
This machine is particularly suitable for one
handed operation, and access to corners
and edges that are otherwise difficult to
reach and require hand sanding. Depending
on the task, you may grip the rear handle
alone, or the rear handle and the top of the
ergonomically contoured soft grip motor
housing, which is designed for this purpose.
Profiles and grooves may be finished using
the tip or edge of the selected accessory,
which should occasionally be rotated during
use to distribute the wear on the accessory
and backing pad surface.
Always be certain that smaller workpieces
are securely fastened to a bench or other
support. Larger panels may be held in place
by hand on a bench or sawhorses.
SANDING: Open-coat aluminum oxide
sanding sheets are recommended for most
wood or metal sanding applications, as this
synthetic material cuts quickly and wears
well. Some applications, such as metal
finishing or cleaning, require special abrasive
pads which are available from your dealer.
For best results, use Bosch sanding and
polishing accessories which are of superior
quality and are carefully selected to produce
professional quality results with your sander.
The following suggestions may be used as a
general guide for abrasive selection, but the
best results will be obtained by sanding a
test sample of the workpiece first.

WARNING
Service
Preventive maintenance
performed by unauthorized
personnel may result in misplacing of
internal wires and components which
could cause serious hazard. We
recommend that all tool service be
performed by a Bosch Factory Service
Center or Authorized Bosch Service Station.
TOOL LUBRICATION
Your Bosch tool has been properly
lubricated and is ready to use. It is
recommended that tools with gears be
regreased with a special gear lubricant at
every brush change.
CARBON BRUSHES
The brushes and commutator in your tool
have been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend
every two to six months the brushes be
examined. Only genuine Bosch replacement
brushes specially designed for your tool
should be used.
BEARINGS
After about 300-400 hours of operation, or at
every second brush change, the bearings
should be replaced at Bosch Factory Service
Center or Authorized Bosch Service Station.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating or
motor failure.
Cleaning
To avoid accidents always
disconnect the tool from
the power supply before cleaning or
performing any maintenance. The tool may
be cleaned most effectively with
compressed dry air. Always wear safety
goggles when cleaning tools with
compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not attempt to clean by inserting pointed
objects through openings.
Certain cleaning agents
and solvents damage
plastic parts. Some of these are: gasoline,
carbon tetrachloride, chlorinated cleaning
solvents, ammonia and household
detergents that contain ammonia.
Maintenance
!
CAUTION
-8-
Grit Application
Coarse For rough wood or metal
sanding, and rust or old
finish removal.
Medium For general wood or metal
sanding
Fine For final finishing of wood,
metal, plaster and other
surfaces.
Extra fine For final sanding of bare
wood, smoothing old paint,
or preparing a finished
surface for recoating.
With the workpiece firmly secured, turn tool
on as described above. Contact the work
with the tool after the sander has reached its
full speed, and remove it from the work
before switching the tool off. Operating your
sander in this manner will prolong switch
and motor life, and greatly increase the
quality of your work.
Move the sander in long steady strokes
parallel to the grain using some lateral
motion to overlap the strokes by as much as
75%. DO NOT apply excessive pressure let the tool do the work. Excessive pressure
will result in poor handling, vibration, and
unwanted sanding marks.
If the surface is rough, begin with coarser
grits and then complete the surfacing with
medium and fine abrasives. To avoid
uneven results, do not skip more than one
grit size when going from coarser to finer,
and do not sand in one area for too long.
When the job is completed, gently lift the
tool from the work surface and slide switch
to the “OFF” position.
POLISHING: Your Bosch corner/detail
sander may be fitted with optional abrasive
mesh or polishing pads to polish or remove
scratches or corrosion from metal, painted,
or other surfaces. The tool is operated in
much the same way as when sanding, but
the following points should be observed;
Use light pressure and a circular or
overlapping motion to remove scratches and
corrosion or polish a surface. If using a
compound, use only as much as necessary
and do not use the dust extraction feature.
When working in very confined areas or
louvered panels, the optional pad extension
plate should be fitted.
Clean the buffing or mesh pads with mild
detergents and warm water. DO NOT use
solvents.
