WARNING – To reduce the risk of injury, user must read instruction manual.

General Safety Rules
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

1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.

c) Keep children and bystanders away while operating a power tool. Distractions

can cause you to lose control

2) Electrical safety
a) 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

b) 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.

c) Do not expose power tools to rain or wet conditions. Water entering a power

tool will increase the risk of electric shock

d) 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.

e) 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.

3) Personal safety
a) 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.

b) 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.

c) 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.

SECTION 1 GENERAL SAFETY RULES

d) 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.

e) Do not overreach. Keep proper footing and balance at all times. This enables

better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair,

clothing and gloves away from moving parts. Loose clothes, jewellery or long
hair can be caught in moving parts.

g) 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.

4) Power tool use and care
a) 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.

b) 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.

c) 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.

d) 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.

e) 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.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp

cutting edges are less likely to bind and are easier to control.

g) 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.

5) Service
a) 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.

CONTENTS – SECTION 2 SPECIFIC SAFETY RULES

Safety Warnings Common for Sanding or Polishing Operations:

a) This power tool is intended to function as a sander or polisher 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.

b) Operations such as grinding, wire brushing or cutting-off are not

recommended to be performed with this power tool. Operations for which the
power tool was not designed may create a hazard and cause personal injury.

c) 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.

d) 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.

e) 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.

f) The arbour size of wheels, flanges, backing pads or any other accessory must

properly fit the spindle of the power tool. Accessories with arbour 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.

g) 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.

h) 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 filtrating particles generated by your
operation. Prolonged exposure to high intensity noise may cause hearing loss.

i) 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.

j) Hold power tool by insulated gripping surfaces only, when performing an

operation where the cutting accessory may contact hidden wiring or its own
cord. Cutting accessory contacting a ″live″ wire may make exposed metal parts of

the power tool ″live″ and shock the operator.

k) 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.

l) 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.

m) 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.

n) Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the

housing and excessive accumulation of powdered metal may cause electrical hazards.

o) Do not operate the power tool near flammable materials. Sparks could ignite these

materials.

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad,
brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled power tool to be forced in the direction
opposite of the accessory’s rotation at the point of the binding.

For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of
the wheel that is entering into the pinch point can dig into the surface of the material
causing the wheel to climb out or kick out. The wheel may either jump toward or away
from the operator, depending on direction of the wheel’s movement at the point of
pinching. Abrasive wheels may also break under these conditions.

Kickback is the result of power tool misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below.

a) Maintain a firm grip on the power tool and position your body and arm to

allow you to resist kickback forces. Always use auxiliary handle, if provided,
for maximum control over kickback or torque reaction during start-up. The

operator can control torque reactions or kickback forces, if proper precautions are
taken.

b) Never place your hand near the rotating accessory. Accessory may kickback

over your hand.

c) Do not position your body in the area where power tool will move if kickback

occurs. Kickback will propel the tool in direction opposite to the wheel’s movement
at the point of snagging.

d) Use special care when working corners, sharp edges etc. Avoid bouncing

and snagging the accessory. Corners, sharp edges or bouncing have a tendency
to snag the rotating accessory and cause loss of control or kickback.

e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such

blades create frequent kickback and loss of control.

Safety Warnings Specific for Sanding Operations:

a) Do not use excessively oversized sanding disc paper. Follow manufacturers

recommendations, when selecting sanding paper. Larger sanding paper

extending beyond the sanding pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.

CONTENTS – SECTION 4 ADDITIONAL SAFETY RULES

The Operating Instructions are to be kept near the location where the
machine is being operated, and must be within reach at all times!

Grounded tools must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances.

Check with a qualified electrician if you are in doubt as to whether the
outlet is properly grounded.

If the tools should electrically malfunction or break down, grounding provides a
low resistance path to carry electricity away from the user. (Applicable only to
Class I [grounded] tools.)

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.

Double insulation eliminates the need for the three wire grounded power cord
and grounded power supply system. (Applicable only to Class II tools.)

Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.

In addition to these Operating Instructions, general and legal regulations
regarding accident prevention and environmental protection must be complied
with and indicated!

Such duties may, for example, relate to the handling of hazardous substances, or
to the provision and wearing of personal protection equipment, as well as
compliance with traffic regulations.

The Operating Instructions are to be kept near the location

where the machine is being operated, and must be within reach
at all times!
