1. SAFETY NOTES
General Power Tool Safety Warnings
Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in elec tric 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.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
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.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power toolsU. nmodified plugs and matching outlets will reduce risk
of electric shock.
Avoid body contact with eart hed or grounded surfaces, such as pipes, radiators, ranges and refri-
gerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
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 and moving parts. Damaged or entangled cords increase the
risk of electric shock.
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.
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.
Personal safety
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.
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.
Prevent unintentional starting. Ensure the switch is in the off-position before co nnecting 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.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left atta-
ched to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery.
Keep your hair, clothing and gloves away from moving parts.L oose clothes, jewellery or long hair
can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facili ties, ensure these
are connected and properly used. Use of dust collection can reduce dust-related hazards.
Power tool use and care
Do not force the power tool. Use the correct power tool for your applicationT. he correct power tool
will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off.A ny power tool that cannot be
controlled with the switch is dangerous and must be repaired.
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.
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.
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. ny accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc. in accordance with these instruct ions, 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.
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.
2. SAFETY WARNINGS FOR ANGLE GRINDER
Safety Warnings common for Grinding, Sanding, Wire
Brushing or Abrasive Cutting Off Operations This power tool is intended to function as a grinder,
sander, 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.
Operations such as polishing are not recommended to be performed with this power tool. Opera-
tions for which the power tool was not designed may create a hazard and cause personal injury.
Do not use accessories which are not specifically designed and recommended by the tool manufac-
turer. Just because the accessory can be attached to your power tool, it does not assure safe
operation.
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.
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.
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. Acces-
sories that do not match the mounting hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
Do not use a damaged access ory. 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 acces-
sory. 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.
Wear personal protective equipment. Depending on application, use face shield, safety goggles or
safety glasses. As appropriate, we ar dust mask, hearing protectors, gloves and shop apron capa-
ble 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 capa-
ble of filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause hearing
loss.
Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal protective equipmentF. ragments of workpiece
or of a broken accessory may fly away and cause injury beyond immediate area of operation.
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.
Position the cord clear of the spinning accessory. If you lose control, the cord may be cut or snag-
ged and your hand or arm may be pulled into the spinning wheel.
Never lay the power tool down until the accessory has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of your control.
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.
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.
Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
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.
Maintain a firm grip on the power tool and position your body and arm to allow you to resist kick-
back 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.
Never place your hand near the rotating accessory. Accessory may kickback over your hand.
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.
Use special care when work ing corners, sharp edges, etc. Avoid bouncing and snagging the acces-
sory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause
loss of control or kickback. 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 Grinding and Abrasive Cutting-Off operations
Use only wheel types that are recommended for your power tool and the specific guard designed
for the selected wheel. Wheels for which the power tool was not designed cannot be adequately
guarded and are unsafe.
The grinding surface of the 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 ade-
quately protected.
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 operator from
broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.
Wheels must be used only for recommended applications.
For example: do not grind with the side of the cut-off wheel.A brasive cut-off wheels are intended
for peripheral grinding; side forces applied to these wheels may cause them to shatter.
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.
Do not use worn down reinforced wheels from larger power tools.W heels intended for larger power
tools are not suitable for the higher speed of a smaller tool and may burst.
Additional safety warnings espcific for abrasive cutting off operations
Do not “jam” the cut-off wheel or apply excessive pressure.
Do not attempt to make an excessive depth of cut.
Overstressing the wheel increa ses the loading and susceptibility to twisting or binding of the wheel
in the cut and the possibility of kickback or wheel breakage.
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.
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.
Do not restart the cutting op eration in the workpiece.
Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kick-
back if the power tool is restarted in the workpiece.
Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight. Supports must be placed under the workpie-
ce near the line of cut and near the edge of the workpiece on both sides of the wheel.
Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protru-
ding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
Safety warnings specific for sanding operations
Do not use excessively oversized sanding disc paper.
Follow manufacturers recommendations, when selecting sanding paperL.a rger sanding paper
extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of
the disc, or kickback.
Safety warnings specific for wire brushing operations
Be aware that wire bristles are thrown by the brush even during ordinary operat ion. Do not overs-
tress the wires by applying excess ive load to the brush. The wire bristles can easily penetrate light
clothing and/or skin.
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.
Additional safety warnings
Wear safety goggles.
Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility
company for assistance contact with electric lines can lead to fire and electric shock. Damaging a
gas line can lead to explosion.
Penetrating a water line causes property damage or may cause an electric shock.
Release the On/Off switch and set it to the off position when the power supply is interrupted, e. g.,
in case of a power failure or when the mains plug is pulled. This prevents uncontrolled restarting.
Do not touch grinding and cutting discs before they have cooled downT. he discs can become very
hot while working.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure
than by hand.
If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in
its place by an authorised customer service agent. The replacement plug should have the same fuse
rating as the original plug.
The severed plug must be disposed of to avoid a possible shock hazard and should never be inser-
ted into a mains socket elsewhere.
Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current
of 30mA or less.
