IMPORTANT SAFETY INFORMATION

General Power Tool Safety Warnings

Read all safety warnings and instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term ″power tool″ in the warnings refers to your mains-operated (corded) power tool.

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.

Electrical Safety

1. 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.

2. 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.

3. Do not expose power tools to rain or wet
conditions. Water entering a power tool

will increase the risk of electric shock.

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 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.

3. Prevent unintentional starting. Ensure the switch/
trigger 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.

4. 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.

5. 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.

6. If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply.

Use of a GFCI reduces the risk of electric shock.

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.

7. If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of

these devices can reduce dust-related hazards.

8. Only use safety equipment that has been
approved by an appropriate standards agency.

Unapproved safety equipment may not provide
adequate protection. Eye protection must
be ANSI-approved and breathing
protection must be NIOSH-approved for
the specific hazards in the work area.

SAFETYOPERATIONMAINTENANCE SETUP

Power Tool Use and Care

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/trigger
does not turn it on and off.

Any power tool that cannot be controlled with the
switch/trigger is dangerous and must be repaired.

3. Disconnect the plug from the power source
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 tool’s 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,
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.

SAFETY OPERATION MAINTENANCESETUP

Service

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.

Safety Warnings Common for Grinding, Sanding, Wire Brushing,
Polishing, or Abrasive Cutting-Off Operations

1. This power tool is intended to function
as a grinder, sander, wire brush, polisher,
or cut-off tool. Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool.

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

2. Do not use accessories which are not

specifically designed and recommended
by the tool manufacturer. Just because the

accessory can be attached to your power tool,
it does not assure safe operation.

3. The rated speed of the accessory must be at

least equal to the maximum speed marked on
the power tool. Accessories running faster than

their RATED SPEED can break and fly apart.

4. The outside diameter and the thickness of your

accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories

cannot be adequately guarded or controlled.

5. The arbor size of wheels, flanges, backing

pads or any other accessory must properly
fit the spindle of the power tool. Accessories

with arbor holes that do not match the mounting
hardware of the power tool will run out of balance,
vibrate excessively and may cause loss of control.

6. Do not use a damaged accessory.

Before each use inspect the accessory such
as abrasive wheels for chips and cracks,
backing pad for cracks, tear or excess wear,
wire brush for loose or cracked wires. If power
tool or accessory is dropped, inspect for
damage or install an undamaged accessory.
After inspecting and installing an accessory,
position yourself and bystanders away from
the plane of the rotating accessory and run
the power tool at maximum no-load speed
for one minute. Damaged accessories will

normally break apart during this test time.

7. Wear personal protective equipment. Depending

on application, use face shield, safety goggles
or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and workshop
apron capable of stopping small abrasive or
workpiece fragments. The eye protection must
be capable of stopping flying debris generated
by various operations. The eye protection must

be capable of stopping flying debris generated by
various operations. The dust mask or respirator
must be capable of filtering out particles generated
by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.

8. Keep bystanders a safe distance away from work

area. Anyone entering the work area must wear
personal protective equipment. Fragments of

workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation.

9. Hold power tool by insulated gripping surfaces

only, when performing an operation where
the accessory may contact hidden wiring
or its own cord. An accessory contacting a

″live″ wire may make exposed metal parts of
the power tool ″live″ and shock the operator.

10. Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or
snagged and your hand or arm may be
pulled into the spinning accessory.

11. Never lay the power tool down until the

accessory has come to a complete stop.

The spinning accessory may grab the surface
and pull the power tool out of your control.

12. Do not run the power tool while carrying
it at your side. Accidental contact with the

spinning accessory could snag your clothing,
pulling the accessory into your body.
