General Power Tool Safety Warnings
WARNING – 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
or battery-operated (cordless) power tool.
2.1 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.
2.2 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
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.
f) If operating a power tool in a damp location is
unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
2.3 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
b) 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.
c) 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 energising power tools
that have the switch on invites accidents.
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
dust collection can reduce dust-related hazards.
2.4 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.
1. Specified Conditions of Use
2. General Safety Information
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
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 tool's 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,
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.
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.
3.1 General Safety Recommendations
for grinding, sanding, wire brushing,
polishing and cutting-off operations:
a) This power tool is intended to function as a
sander (not PE 15-20 RT) or polisher. 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, sanding, 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 external diameter and thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
f) Threaded mounting of accessories must
match the sanding spindle thread. For
accessories mounted by flanges, the arbour
hole of the accessory must fit the locating
diameter of the flange. Accessories 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 a power tool or
accessory is dropped, inspect for damage or
install an undamaged accessory. After
inspecting and installing the 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. Use a
face shield, safety goggles or safety goggles
depending on the application. As appropriate,
wear a dust mask, hearing protectors, gloves
and a 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 dust mask or
respirator must be capable of filtering 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 a workpiece or broken accessory may fly away
and cause injury beyond the immediate area of
j) Hold the power tool by the insulated gripping
surfaces only when performing an operation
where the 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 rotating
accessory. If you lose control, the cord may be cut
or snagged and your hand or arm may be pulled into
the rotating accessory.
I) Never lay the power tool down until the
accessory has come to a complete stop. The
rotating 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 rotating
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
3. Special Safety Instructions
and excessive accumulation of powdered metal
may cause electrical hazards.
o) Do not operate the power tool near
flammable materials. Sparks could ignite these
p) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
3.2 Kickback and related warnings
Kickback is a sudden reaction to a pinched or
snagged sanding 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 abrasive wheel may either jump
toward or away from the operator, depending on
direction of the disc’s movement at the point of
pinching. Abrasive wheels may also break under
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and
can be avoided if suitable precautionary measures
are taken as described 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 the
additional handle, if provided, for maximum
control over kickback or a torque reaction
during start-up. The operator can control torque
reactions or kickback forces if proper precautions
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
c) Do not position your body in the area
where the power tool will move if kickback
will propel the tool in direction opposite to the
grinding wheel’s movement at the point of
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.
3.3 Safety Warnings Specific for Sanding
Operations (not PE 15-20 RT):
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.
3.4 Safety Warnings Specific for Polishing
Do not allow any loose portion of the polishing
bonnet or its attachment strings to spin freely.
Tuck away or shorten the loose attachment
strings. Loose and spinning attachment strings
can entangle your fingers or snag on the workpiece.
Caution: The workpiece can heat up
during the polishing process!
3.5 Additional safety instructions:
WARNING – Always wear protective
