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
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.
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
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
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 tools. Carrying power tools with your
finger on the switch or plugging in power tools that have the switch on invite 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.

H. This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a person responsible for their safety.
i. Children should be supervised to ensure they do not play with the appliance.
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 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.
WARNING: RECOMMENDATION FOR THE USE OF A RESIDUAL
CURRENT DEVICE WITH A RATED RESIDUAL CURRENT OF 30Ma OR LESS
WARNING: IT IS RECOMMANDED THAT A SAFETY PACK IS USED WITH
ANY PORTABLE POWER TOOL.

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 work piece, 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 Common for Grinding, Wire Brushing, or Abrasive Cutting-Off
Operation:
a) This power tool is intended to function as a grinder, wire brush, 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.
b) Operations such as sanding and polishing 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 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 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 grinder 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 the
power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After
inspecting or installing a new 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 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 broken accessory may fly away and cause
injury beyond immediate area of operation.
j) 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.
k) Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snagged
and your hand of 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.
p) Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in
electrocution or shock.
Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations:
a) Use only wheel types that are recommended for your power tool and the specific guard designed for
the selected wheel. Wheels for which power tool was not designed cannot be adequately guarded and are
unsafe.
b) The grinding surface of centre depressed wheels must be mounted below the plane of the guard lip.
An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately
protected.
c) The guard must be securely attached to the power tool and positioned for maximum safety, so the
least amount of wheel is exposed towards the operator. The guard helps to protect the operator from
broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.

d) Wheels must be used only for recommended applications. For example: do not grind with the side of
cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these
wheels may cause them to shatter.
e) Always use undamaged wheel flanges that are of correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
f) Do not use worn down wheels from larger power tools. Wheel intended for larger power tool is not
suitable for the higher speed of a smaller tool and may burst.
Additional Safety Warnings Specific from Abrasive Cutting-Off Operations:
a) Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the
wheel in the cut and the possibility of kickback or wheel breakage.
b) Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible kickback may propel the spinning wheel and the
power tool directly at you.
c) When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-
off wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the work piece. Let the wheel reach full speed and carefully re-
enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the work piece.
e) Support panels or any oversized work piece to minimize the risk of wheel pinching and kickback. Large
work pieces tend to sag under their own weight. Supports must be placed under the work piece near the
line of cut and near the edge of the work piece on both sides of the wheel.
f) Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
Safety Warnings Specific for Wire Brushing Operations:
a) Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress
the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing
and/or skin.
b) If the use of a guard is recommended for wire brushing, do not allow any interference of the wire
wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and
centrifugal forces.
