2. General safety instructions
For your own protection and for the protection of your electrical tool, pay attention to all parts of the text that are marked with this symbol!
WARNING – Reading the operating instruc­tions will reduce the risk of injury.
Pass on your electrical tool only together with these documents.
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.
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 out-
lets will reduce risk of electric shock.
4
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.
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 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 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.
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 acci-
dents 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.
2.5 Battery tool use and care a) Recharge only with the charger specified by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fire when used with another battery pack.
b) Use power tools only with specifically desig­nated battery packs. Use of any other battery
packs may create a risk of injury and fire.
c) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals
together may cause burns or a fire.
d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irri-
tation or burns.
2.6 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.

3. Special Safety Instructions
3.1 Safety Warnings Common for Grinding, Sanding, Wire Brushing, Polishing or Abrasive Cutting-Off Operations:
Use a) This power tool is intended to function as a
grinder, sander, wire brush, polisher or cut-off tool. Read all illustrations and specifications provided with this power tool. Failure to follow all the instructions
may result in electric shock, fire and/or serious injury.
b) Do not use any accessories that 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.
c) 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. d) The outside diameter and the thickness of
your accessory must be within the capacity rating of your power tool. Incorrectly sized acces-
sories cannot be adequately guarded or controlled. e) 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.
f) Do not use damaged accessories. Before
each use, inspect accessories 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, check it 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. g) Wear personal protective equipment.
Depending on application, use a 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 filtering particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
h) Keep bystanders a safe distance away from
the 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.

ENGLISHen
i) 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. A cutting acces-
sory that comes in contact with a "live" wire may render exposed metal parts of the power tool "live" and give the operator an electric shock.
j) Position the cord clear of the spinning acces- sory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
k) Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory may grip the surface and pull the power tool out of your control.
l) 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.
m) 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.
n) Do not operate the power tool near flam- mable materials. Sparks could ignite these mate­rials.
o) 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 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 to the accessory’s rotation at the point of jamming.
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 the 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. Kick-
6
back will propel the tool in a direction opposite to the wheel’s movement at the point of snagging.
d) Use special care when working around
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 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 the power tool was not designed cannot be adequately guarded and are unsafe.
b) Wheels must be used only for recommended
applications. For example: do not grind with the side of the cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
c) Always use undamaged wheel flanges that
are the 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.
d) Do not use worn down wheels from larger power tools. Wheels intended for larger power tools are not suitable for the higher speed of a smaller tool and may burst.
3.4 Additional Safety Warnings Specific for Abrasive Cutting-Off Operations:
a) Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make excessively deep cuts. 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) If the wheel jams or if you interrupt 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 the wheel jam. d) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may jam,
walk up or kickback if the power tool is restarted in the workpiece.
e) Support panels or any oversized workpiece
to minimise the risk of wheel pinching and kick-
back. Large workpieces tend to sag under their own
weight. Supports must be placed under the work­piece near the line of cut and near the edge of the workpiece 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.
3.5 Safety Warnings Specific for Sanding Operations:
a) Do not use oversized sanding disc paper. Follow manufacturer's 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.
3.6 Safety Warnings Specific for Polishing Operations:
a) Loose parts on the polishing guard, espe­cially the fastening cords, are not permitted. Tuck away or shorten the fastening cords.
Loose, spinning fastening cords may make contact with your fingers or become caught in the work­piece.
3.7 Safety Warnings Specific for Wire Brush­ing Operations:
a) Be aware that wire bristles are lost 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.
3.8 Additional Safety Instructions
WARNING – Always wear protective
goggles.
Use elastic cushioning layers if they have been supplied with the abrasive and if required.
Observe the specifications of the tool or accessory manufacturer! Protect the discs from grease or impacts!
Abrasives must be stored and handled with care in accordance with the manufacturer's instructions.
Never use parting grinder discs for roughing work. Do not apply pressure to the side of parting grinder discs.
The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be supported adequately.
Engage the spindle locking button (4) only when the motor is inoperative. (GA 18 LTX, GE 710 Plus, GA 18 LTX G, GE 950 G Plus)
Keep hands away from the rotating tool! Remove chips and similar material only when the machine is at a standstill.
ENGLISH en
Prior to use, ensure that the coated abrasive is properly fitted and secured. Run the tool in idling for 60 seconds in a safe position and bring to a stand­still immediately if there are significant vibrations or if other deficiencies are determined. If such a situa­tion occurs, check the machine to determine the cause.
Ensure that sparks produced during work do not constitute a risk to the user or other personnel and are not able to ignite inflammable substances. Endangered areas must be protected with flame­resistant covers. Make sure that fire-risk areas are always provided with suitable fire extinguishers.
Dust from material such as paint containing lead, some wood species, minerals and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders. Certain kinds of dust are classified as carcinogenic such as oak and beech dust especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos must only be treated by specialists.
- Where the use of a dust extraction device is possible it shall be used.
- The work place must be well ventilated.
- The use of a dust mask of filter class P2 is recom­mended.
Follow national requirements for the materials you want to work with.
Materials that generate dusts or vapours that may be harmful to health (e.g. asbestos) must not be processed.
When working in dusty conditions, ensure that ventilation openings are not blocked. If it becomes necessary to remove dust, first disconnect the power tool from the mains supply (use non-metallic objects) and avoid damaging internal components.
Damaged, eccentric or vibrating tools must not be used.
In the interests of safety, ensure that the rubber sleeve (3) or additional handle is fitted while working (5).
3.9 Special safety instructions for mains
powered machines:
Pull the plug out of the plug socket before any adjustments, conversions or servicing are performed.
During machining, of metals in
deposits inside the machine. This can lead to the transfer of electrical energy onto the machine housing. This can mean a temporary danger of electric shocks. This is why it is necessary when the machine is running to blow compressed air through the rear ventilation slots of the machine regularly, frequently and thoroughly. Here, the machine must be held firmly.
We recommend using a stationary extractor system and connecting a residual current circuit-breaker (RCD) upstream. When the machine is shut down via the FI circuit-breaker, it must be checked and
