extraction and collection facilities, ensure these are
connected and properly used. Use of these devices can
reduce dust-related hazards.
WARNING:
Read all instructions Failure to follow all
instructions listed below may result in electric
shock, fire and/or serious injury. The term “power
tool” in all of the warnings listed below refers
to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
WORk AREA SAFETY
keep work area clean and well lit. Cluttered or 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.
Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
POWER TOOL USE AND CARE
Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. keep cord away
from heat, oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric
shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under the
influence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result in
serious personal injury.
Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
Use the power tool, accessories and tool bits etc., in
accordance with these instructions and in the manner
intended for the particular type of power tool, taking
into account the working conditions and the work
to be performed. Use of the power tool for operations
different from those intended could result in a hazardous
situation.
Avoid accidental starting. Ensure the switch is in the
off-position before plugging in. Carrying power tools
with your finger on the switch or plugging in power tools
that have the switch on invites accidents.

ELECTRICAL
DOUBLE INSULATION
EXTENSION CORDS
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are isolated
from the internal metal motor components with protecting
insulation. Double insulated tools do not need to be
grounded.
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the tool will draw. An
undersized cord will cause a drop in line voltage, resulting in
overheating and loss of power. Use the chart to determine
the minimum wire size required in an extension cord. Only
round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
WARNING:
When working outdoors with a tool, use an extension
cord that is designed for outside use. This type of cord is
designated with “WA” on the cord’s jacket.
The double insulated system is intended to protect
the user from shock resulting from a break in the
tool’s internal wiring. Observe all normal safety
precautions to avoid electrical shock.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
NOTE: Servicing of a tool with double insulation requires
extreme care and knowledge of the system and should
be performed only by a qualified service technician. For
service, we suggest you return the tool to your nearest
authorized service center for repair. Always use original
factory replacement parts when servicing.

OPERATION
APPLICATIONS
You may use this product for the purposes listed below:
WARNING:
Do not allow familiarity with products to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict serious injury.
Sanding wood, metals, and plastics
Smoothing rough boards, chamfering, rounding edges
Removing rust, paint, varnishes, and stains
WARNING:
WARNING:
If your sanding job becomes dusty or if you have a
breathing condition, wear a dust mask or respirator
to prevent damage to your health.
Always wear safety goggles or safety glasses with
side shields when operating power tools. Failure
to do so could result in objects being thrown into
your eyes resulting in possible serious injury.
SELECTING SANDING BELTS
Selecting the correct size and type of sanding belt is an
important step in achieving a high quality sanded finish. Alu-
minum oxide, silicon carbide, and other synthetic abrasives
are best for power sanding.
WARNING:
Do not use any attachments or accessories
not recommended by the manufacturer of this
product. The use of attachments or accessories
not recommended can result in serious personal
injury.
In general, when sanding, coarse grit removes the most ma-
terial and fine grit produces the best finish. The condition of
the surface to be sanded determines which grit will do the
best job. If the surface is rough, start with a coarse grit and
sand until the surface is uniform. Then use medium grit to
remove scratches left by the coarser grit. Finally, use finer
grit for finishing the surface. Always continue sanding with
each grit until the surface is uniform.
WARNING:
Before connecting the sander to a power supply,
make sure it is not in the locked-on position. Failure
to do so could result in accidental starting of the
tool resulting in serious injury.

Tighten all brush caps securely. Do not over tighten.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to accelerated
wear and possible premature failure because the fiberglass
chips and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommended
using this tool for extended work on these types of materials.
However, if you do work with any of these materials, it is
extremely important to clean the tool using compressed
air.
