WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
4. Make your workshop childproof with padlocks and master switches. Lock tools away
when not in use.
5. MAKE SURE the work area has ample lighting so you can see the work and that
there are no obstructions that will interfere with safe operation BEFORE using your
power tool.
PERSONAL SAFETY
1. 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.
2. Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injuries.
3. Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energizing power tools that have
the switch on invites accidents.
4. Remove any adjusting key or wrench before turning the power tool on. A wrench
or a key left attached to a rotating part of the power tool may result in personal injury.
5. Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in
moving parts.

can reduce dust-related hazards.
TOOLUSEANDCARESAFETY
Z_ WARNING: BE SURE to read and understand all instructions before
operating this power tool. Failure to follow all instructions listed below may
result in electric shock, fire and/or serious personal injury.
1. 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.
2. 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.
3. 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.
4. 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.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may affect the power tools operation. If
damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
7. 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.
8. Use clamps or another practical way to secure and support the workpiece to a
stable platform.
9. Holding the work by hand or against your body leaves it unstable and may lead to
loss of control.
Z_ WARNING: Empty dust bag before storage to help prevent possible fire
hazard, especially when resin coating or linseed oil finishes have been sanded.
ELECTRICAL SAFETY
/_, WARNING: Do not permit fingers to touch
the terminals of plug when installing or removing
the plug from the outlet.
1. 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.

ELECTRICAL SAFETY
2 Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with grounded power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
/_, WARNING: Double insulation DOES NOT take the place of normal safetyprecautions when operating this tool.
3. 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.
4. Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
5. 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.
6. When operating a power tool outdoors, use an extension cord suitable for outdoor
use marked "W-A" or "W". Use of a cord suitable for outdoor use reduces the risk of
electric shock.
7. If operating a power tool in a damp location is unavoidable, use a Ground Fault
Circuit Interupter (GFCI) protected supply. Use of a GFCI reduces the risk of
electric shock.
EXTENSION CORDS
USE PROPER EXTENSION CORD. Make sure your extension cord is in good
condition. When using an extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized cord will cause a c]rop in
line voltage resulting in loss of power and overheating.Table 1 shows the correct
size to use depending on cord length and nameplate ampere rating. If in doubt,
use the next heavier gage. The smaller the gage number, the heavier the cord.

SERVICE SAFETY
1. If any part of this tool is missing or should break, bend, or fail in any way;
or should any electrical component fail to perform properly: SHUT OFF the
power switch and remove the tool's plug from the power source and have the
missing, damaged or failed parts replaced BEFORE resuming operation.
2. Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
3. If the replacement of the supply cord is necessary, this has to be done by the
manufacturer or his agent in order to avoid s safety hazard.
SAFETY RULES FOR POWER SANDERS
1. HOLD TOOL by insulated gripping surfaces when sanding where tool may contact
hidden wiring, such as walls, floors, or its own power cord. Contact with a "live" wire will
make exposed metals parts of the tool "live" and shock the operator.
2. INSPECT FOR AND REMOVE all nails, screws, staples or any embedded pieces
of metal from surface to be sanded. These protrusions could damage the sandpaper,
the cushion of the sander and cause loss of control. Following this rule will reduce the
risk of serious personal injury and damage to the sander.
3. NEVER use this or any power sander for wet sanding or liquid polishing.
Failure to follow this rule will increase the risk of electric shock.
4. ALWAYS clamp the workpiece securely so it will not move under the sander.
Unsecured work could be thrown towards the operator, causing injury.
5. DO NOT force the sander. The weight of the sander supplies adequate
pressure. Let the sander and the grit on the sandpaper do the work.
6. DO NOT sand in any one place for too long. The sander's rapid action may
remove too much material and make the surface uneven.
Z_ WARNING: Some dust crested by using power tools contains chemicals
known to the State of California to cause cancer and 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.
, Arsenic and chromium, from chemically treated lumber.
Your risk from these exposures varies, depending upon how often you do
this type of work. To reduce your exposure to these chemicals:
• Work in a well-ventilated area.
, Work with approved safety equipment, such as those dust masks that
are specially designed to filter out microscopic particles.
Avoid prolonged contact with dust from power sanding, sawing, grinding,
drilling and other construction activities. Wear protective clothing and wash
exposed areas with soap and water. Allowing dust to get into your mouth,
eyes, or lay on the skin may promote absorption of harmful chemicals.
Z_ WARNING: Use of this tool can generate and/or disburse dust, which may
cause serious and permanent respiratory or other injury. Always use
NIOSH/OSHA approved respiratory protection appropriate for the dust exposure.
Direct particles away from face and body.
z_ WARNING: Collected sanding dust from sanding surface coatings
(polyurethane, linseed oil, etc.) can self-ignite in sander dust bag or elsewhere
and cause fire. To reduce risk, empty dust bag frequently and strictly follow
sander manual and coating manufacturer's instructions.
z_ CAUTION: When working on metal surfaces, DO NOT use the dust bag or
a vacuum cleaner because sparks are generated. Wear safety glasses and s dust
mask. Due to the danger of fire, do not use your sander to sand magnesium
surfaces. Do not use for wet sanding.
SANDING PAINTS
SANDING LEAD BASED PAINT is NOT RECOMMENDED due to the difficulty of
controlling the contaminated dust. The greatest danger of lead poisoning isto children
and pregnant women.
Since it is difficult to identify whether or not a paint contains lead without a chemical
analysis we recommend the following precautions when sanding any paint:
• NO children or pregnant women should enter the work area where the
paint sanding is being done until all clean up is completed.
A dust mask or respirator should beworn by all persons entering the work
area. The filter should be replaced daily, or whenever (if) the wearer has
difficulty breathing.
