General Power Tool Safety Warnings
WARNING! Read all safety warnings and all instructions.
Failure to follow the warnings and instructions
may result in electric shock, fire and/or serious
injury.
Please save this instruction manual. Save all warnings and instructions for
future reference. Please ensure you give this instruction manual to the next
person that uses this product.
The term "power tool" in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
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 the 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.
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.
3. Personal Safety:
Safety Instructions
9

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 personal protective equipment. Always wear eye protection. Protective
equipment such as a 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.
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 tool’s
Safety Instructions
10

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.
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.
b. If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent, or a similarly qualified person in order to avoid a hazard.
Safety warnings common for sanding operation
a. This power tool is intended to function as a sander. 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, polishing 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 causeloss of control.
g. Threaded mounting of accessories must match the grinder spindle thread.
For accessories mounted by flanges, the arbour hole of the accessory must
Safety Instructions
11

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.
h. 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.
i. 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 dust mask or
respirator must be capable of filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause hearing loss.
j. 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.
k. Hold the 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 could give the operator an electric shock.
l. 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.
m.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.
n. 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.
o. 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.
p. Do not operate the power tool near flammable materials. Sparks could ignite
these materials.
Safety Instructions
12

q. Do not use accessories that require liquid coolants. Using water or other
liquid coolants may result in electrocution or shock.
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 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.
