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.
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.
Read and understand all instructions. Failure to follow all instructions
listed below, may result in electric shock, fire and/or serious personal injury.

WARNING
Power Tool Safety Rules
-3-
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.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced or
pinched, safety guard return springs may be
improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of
electric shock or injury. Certain cleaning
agents such as gasoline, carbon tetrachloride,
ammonia, etc. may damage plastic parts.
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.
Always wear eye protection and a dust
mask for dusty applications and when
sanding overhead. Sanding particles can
be absorbed by your eyes and inhaled easily
and may cause health complications.
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.

DUST EXTRACTION
The integral dust extraction system collects
sanding dust in the dust bag. For maximum
efficiency, cloth bags should be emptied
when they are no more than half full, and
should be replaced when the surface
becomes clogged with dust or efficiency will
be reduced. To replace bag, slide connector
in direction of arrow A until it stops. Insert
bag support into the pocket provide on bag.
Then slide bag and support in direction of
arrow B onto connector and dust port (Fig. 4).
A vacuum hose and adaptor (optional
accessories) are also available which will
allow your random orbit sander to be
connected to a shop vacuum system (Fig. 5).

FRONT HANDLE
Your sander is equipped with a removable
front handle when sanding in tight quarters. To
remove handle, remove screw with allen
wrench provided. Always reinstall handle for
normal operation. Depending on the task, you
may grip the rear handle alone, the rear handle
and the front handle, or the rear handle and the
top of the ergonomically contoured soft grip
motor housing, which is designed for that
purpose (Fig. 1).
SANDING TIPS
This sander has been designed for even
weight distribution which virtually eliminates
the use of pressure. Excessive pressure to the
sander may result in an uneven sanding job
and premature grit wear. Constant and
excessive pressure can cause overheating and
possible damage to the motor.
It's usually best to work in strokes that parallel
the grain, using some lateral motion so the
main strokes are overlapped as much as 75%.
If the surface is rough, start sanding with a
coarse grit sheet, then medium and then finish
with a fine or extra fine abrasive. This
procedure will vary with different types of
materials and work. Continue to sand with
each grit until the surface looks uniform. When
going from one grit size to a finer size, do not
skip more than two sizes.
To remove the greatest amount of stock, use a
coarse grit and move the sander steadily over
the entire surface against the grain as well as
with the grain. DO NOT REMAIN IN ONE
SPOT TOO LONG. It may remove too much
material and uneven sanding will result.
Sanding with the grain of the wood gives the
smoothest final finish.
Additional abrasive sheets can be conveniently
cut from large-size commercially available
sheets (standard size 9" x 11" (228 x 280mm).
Cut into two pieces of equal size. Choose the
proper grit for the job.

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
Accessories
If an extension cord is
necessary, a cord with
adequate size conductors that is capable
of carrying the current necessary for your
tool must be used. This will prevent
excessive voltage drop, loss of power or
overheating. Grounded tools must use 3wire extension cords that have 3-prong
plugs and receptacles.
NOTE: The smaller the gauge number, the
heavier the cord.
