• DISCONNECT TOOLS. When not in use,
before servicing, or when changing blades,
bits, cutters, etc.
• STORE IDLE TOOLS. When not in use,
tools should be stored in dry, high or locked up
place - out of the reach of children.
• DO NOT ALTER OR MISUSE TOOL.
These tools are precision built. Any alterations
or modifications not specified is misuse and
may result in a dangerous condition.
• THE USE OF ANY ACCESSORIES not
specified in this manual may create a hazard.
• MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for better and safer perfor-
mance. Follow instructions for lubricating and
changing accessories. Inspect tool cords peri-
odically and if damaged, have repaired by au-
thorized service facility. Inspect extension
cords periodically and replace if damaged. Keep
handles dry, clean and free from oil and 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
and properly repaired or replaced. Have defec-
tive switches replaced. Do not use tool if switch
does not turn it on or off.
• ALL REPAIRS, ELECTRICAL OR ME-
CHANICAL, should be attempted only by
trained repairmen. Contact the nearest Bosch
Factory Service Center, or Bosch Authorized
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
dusty applications and when sanding over-head.
• When sanding chemically pressure treated
lumber, paint that may be lead based, or any
other materials that may contain carcinogens,
BM 2610991835 9/96
use special precautions. A suitable breathing
respirator must be worn by all personal 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.
• Do not use sandpaper intended for larger
sanding pads. Larger sandpaper will extend
beyond the sanding pad causing snagging, 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. Do not throw sanding dust on an open fire.
Spontaneous combustion, may in time, result
from mixture of oil or water with dust particles.

Double Insulated Tools

• Double Insulation
used in electric power tools which eliminates
the need for the three wire grounded power cord
and grounded power supply system. It is a
recognized and approved system by
Underwriter's Laboratories, CSA and Federal
OSHA authorities.
IMPORTANT:
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.
POLARIZED PLUGS: If your tool is 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 the
proper outlet. To reduce the risk of electric
shock do not change the plug in any way.
