TIONS”. FailuretofollowtheSAFETYRULES
identified by the BULLET (•) symbols listed
BELOW and other safety precautions, may
result in serious personal injury. Keep these
operating instructions with this product.
GENERAL SAFETY RULES
for all Power Tools
Work Area
• KEEP WORK AREAS CLEAN. Cluttered
areas and benches invite accidents.
• AVOID DANGEROUS ENVIRONMENT.
Don’tusepowertoolsindamporwetlocations.
Do not expose power tools to rain. Keep work
area well lit.
• AVOID GASEOUS AREAS. Do not oper-
ate portable electric tools in explosive atmo-
spheres in presence of flammable liquids or
gases. Motors in these tools normally spark,
and the sparks might ignite fumes.
• KEEP CHILDREN AWAY. Do not let
visitors contact tool or extension cord. All
visitors should be kept away from work areas.
Personal Safety
• GUARD AGAINST ELECTRIC SHOCK.
Prevent body contact with grounded surfaces
suchaspipes, radiators,rangesand refrigerator
enclosures. Rubber gloves and non-skid foot-
wear are recommended when working out-
doors, where damp or wet ground may be
encountered. A Ground Fault Circuit Inter-
rupter protected power line must be used for
these conditions.
• DRESS PROPERLY. Do not wear loose
clothing or jewelry. They can be caught in
movingparts. Wearprotectivehaircovering to
contain long hair.
• USE SAFETY EQUIPMENT. WEAR
SAFETY GOGGLES or glasses with side
shields. Wear hearing protection during ex-
tended use of power tools and dust mask for
dusty operations.
• STAY ALERT. USE COMMON SENSE.
Watchwhat you are doing. Do notoperate tool
when you are tired or under influence of drugs.
•
REMOVE ADJUSTING KEYS AND
WRENCHES. Formhabitofcheckingtoseethat

• AVOIDACCIDENTALSTARTING. Don’t
carry plugged in tool with finger on switch. Be
surethe switch isOFF beforebeing plugged in.
• DON’T OVERREACH. Keep proper foot-
ing and balance at all times.
• BEFORE CONNECTING THE TOOL to a
power supply (receptacle, outlet, etc.) be sure
the voltage supplied is the same as that speci-
fied on the tool’s nameplate. A power supply
with voltage greater than that specified for the
tool can result in serious injury to the user - as

Tool Use and Care
• DON’T FORCE TOOL. It will do the job
better and safer at the rate for which it was
designed.
• USE RIGHT TOOL. Don’t force small tool
orattachmenttodothejobofaheavy-dutytool.
Don’t use tool for purpose not intended - for
example; don’t use a circular saw for cutting
tree limbs or logs.
• SECURE WORK. Use clamps or a vise to
hold work. It’s safer than using your hand and
it frees both hands to operate the tool.
• DON’TABUSECORD. Nevercarrytoolby

thorized service facility. Inspect extension
cordsperiodicallyandreplaceifdamaged. Keep
handlesdry, cleanand freefrom oiland grease.
• CHECK DAMAGED PARTS. Before fur-
ther use of the tool, a guard or other part that is
damaged should be carefully checked to deter-
mine that it will operate properly and perform
its intended function. Check for alignment of
moving parts, binding of moving parts, break-
age of parts, mounting, and any other condi-
tions that may affect its operation. A guard or
other part that is damaged should be promptly
andproperly repairedor replaced. Have defec-
tiveswitchesreplaced. Donotusetoolifswitch

Service Center or other competent repair cen-
ter. Use only Bosch replacement parts, any
other may create a hazard.
Pad Sander Safety Rules
• Wear safety goggles and a dust mask for
dustyapplicationsandwhensandingover-head.
• When sanding chemically pressure treated
lumber, paint that may be lead based, or any
other materials that may contain carcinogens,
use special precautions. A suitable breathing
respiratormustbewornbyallpersonalentering
the work area. Work area should be sealed by
plasticsheetingandpersonsnotprotectedshould
bekeptoutuntilworkareaisthoroughlycleaned.
• Do not wet sand with this sander.
• Do not use sandpaper intended for larger
sanding pads. Larger sandpaper will extend
beyondthesandingpadcausingsnagging,tear-
ing of the paper or kick-back. Extra paper
extending beyond the sanding pad can also
cause serious lacerations.
• 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 explo-
sive. Donotthrowsandingdustonanopenfire.
Spontaneous combustion, may in time, result
frommixtureofoilor water withdustparticles.
Double Insulated Tools
• Double Insulation is a design concept
used in electric power tools which eliminates
theneedforthethreewiregroundedpowercord
and grounded power supply system. It is a
recognized and approved system by
Underwriter’s Laboratories, CSA and Federal
OSHA authorities.
IMPORTANT: Servicing of a tool with
double insulation requires care and knowledge
of the system and should be performed only by
a qualified service technician. WHEN SER-
VICE IS REQUIRED USE ONLY IDENTI-
CAL REPLACEMENT PARTS.
POLARIZEDPLUGS: Ifyourtoolisequipped
with a polarized plug (one blade is wider than
the other), this plug will fit in a polarized outlet
onlyoneway. Iftheplugdoesnotfitfullyinthe
outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install the
proper outlet. To reduce the risk of electric
shock do not change the plug in any way.

Extension Cords
• Replacedamagedcordsimmediately.Useof
damaged cords can shock, burn or electrocute.
• Ifan extension cordis necessary,a cordwith
adequate size conductors should be used to
prevent excessive voltage drop, loss of power
or overheating. The table below shows the
correct size to use, depending on cord length
andamperageratingonthetool’snameplate. If
in doubt, use the next heavier gauge. Always
use U.L. and CSA listed extension cords.

Bosch Orbital Pad Sanders are designed to
produceexceptionalfinishesonwoodsurfaces,
and also to remove lacquer, varnish, and other
coatings.
Orbital sanding provides fast, smooth final fin-
ishes. Andthismodelcansandflushonallthree

cabinets, desks and shelving.
Abrasive Sheets
Aluminum oxide, silicon carbide, or other syn-
thetic abrasives are recommended for power
sanding use. Natural abrasives, such as flint or
garnet sheet are too soft for economical use in
power sanding.
For best results, use Bosch abrasive sheets:
Theuniformspacingbetweengrainsminimizes
filling or loading. The high quality aluminum
oxide sheet with heavy backing cuts faster and
lasts longer.
Thefollowingarerecommendedabrasivesheets
and applications:
1. Coarse Grit: For rough wood sanding.
2. Medium Grit: For general wood sanding.
3. Fine Grit: For smoothing wood or plaster
patches.
4. Extra Fine Grit: For final sanding bare
wood and smoothing old paint.
Attaching Abrasive Sheet
1. To open clamper grip, lift up clamp lever 2
so its positioned as shown.
2. Place the abrasive sheet (grit side up) be-
tweentheclamper grip andthe base platewhile
aligning edges of the abrasive sheet with either
edge of the pad. (Pre-bending the sheet makes
attachment easier.)
3. After inserting the sheet, push clamp lever
down making sure the teeth of the clamper grip
are secure.
Operating the Tool
Rocker “ON/OFF” Switch
TO TURN THE TOOL “ON” or “OFF” : Push
IN the switch rocker 1tothe left or right sideof
the tool.
Always hold the sander off the work when
turningtheswitch“ON”or“OFF”. Contactthe
work with the tool after the sander has reached
its full speed and remove it from the work
before turning the switch “OFF”. Operating in
this manner will prolong switch and motor life
and will greatly increase the quality of your
work.
WARNING! Always disconnect the plug

4. Wrap the sheet around the length of the pad
and attach free end of sheet under opposite
clamp and repeat procedures 1, 2, & 3 above.
The abrasive sheet must be drawn as tight as
possiblefor efficient sanding, a loose sheet can
slip on the work surface.
After the paper has been installed, it will be
necessarytopunchholesintothepaperwiththe
use of the punch plate provided with your

and push down on sander until punch plate 9
pierces the paper. Then remove punch plate
from sander.
Sanding Tips
This sander has been designed for even weight
distributionwhichvirtuallyeliminatestheneed
for pressure. Excessive pressure to the sander
mayresultinanunevensandingjobandprema-
turegritwear. Constantandexcessivepressure
can cause overheating and possible damage to
the motor.
It’s usually best to work in strokes that parallel
thegrain,usingsomelateralmotionsothemain
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 proce-
dure will vary with different types of materials
andwork. Continueto sandwith each grituntil
the surface looks uniform. When going from
onegritsizetoafinersize,donotskipmorethan
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. Sand-

cut from large-size commercially available
sheets (standard size: 228 x280mm; 9 x 11-1/
