Operating Instructions

1. Specified Use
The machine, when fitted with original Metabo accessories, is suitable for grinding, sanding, sepa­rating and wire brushing metal, concrete, stone and similar materials without the use of water.
The use of extension pieces or adapters is not permitted.
The user bears sole responsibility for any damage caused by improper use.
Generally accepted accident prevention regula­tions and the enclosed safety information must be observed.
2. General Safety Instructions
WARNING – Reading the operating instructions will reduce the risk of injury.
For your own protection and for the protection of your power tool pay attention to all parts of the text that are marked with this symbol!
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 mains­operated (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 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.
ENGLISH en
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
evice (RCD) protected supply. Use of an
d
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 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
5
ENGLISHen
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 mea ures 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 misalign-
ment 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.
3. Special Safety Instructions
3.1 Safety Warnings Common for Grinding, Sanding, Wire Brushing or Abrasive Cut­ting-Off Operations:
a) This power tool is intended to function as a grinder, sander, wire brush or cut-off tool. Read
safety warnings,
all and specifications provided with this power tool. Failure to follow all the instructions may result
in electric shock, fire and/or serious injury. b) Operations such as polishing are not recom-
mended 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 specif-
ically 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.
6
instructions, illustrations
e) 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. 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 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 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. 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 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 workpiece or of a broken accessory may fly away and cause injury beyond immediate area of opera­tion.
j) Hold 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 shock the operator.
k) 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.
I) 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.
Do not run the power tool while carrying it at
m) 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 flam- mable 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.
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.
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.
3.3 Safety Warnings Specific for Grinding and 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) 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
ENGLISH en
the operator from broken fragments, accidental contact with the wheel and sparks which could ignite clothing.
c) Wheels must be used only for recommended
applications. For example: do not grind with the side of cut­off wheel. Abrasive cut-off wheels are intended for
peripheral grinding, side forces applied to these wheels may cause them to shatter.
ys use undamaged wheel flanges that
d) Alwa 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.
e) 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 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
workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may bind,
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 kick­back. 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 excessively oversized sanding disc paper. Follow manufacturer's recommen­dations when selecting sanding paper. Larger
sanding paper extending beyond the sanding pad
7
ENGLISHen
presents a laceration hazard and may cause snag­ging, tearing of the disc or kickback.
3.6 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.
3.7 Additional Safety Instructions
WARNING – Always wear protective
goggles.
For safety reasons the guard must protrude at least 9/64" (3.4 mm) beyond the wheel. Double check especially wheels with an included hub.
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!
Grinding discs 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 sufficiently supported.
If accessories with threaded inserts are used, the end of the spindle may not touch the base of the hole on the grinding tool. Make sure that the thread in the accessory is long enough to accommodate the full length of the spindle. The thread in the accessory must match the thread on the spindle. See page 2 and chapter 13. Technical Specifica­tions for more information on the spindle length and thread.
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 (FI) upstream. When the angle grinder is shut down via the FI circuit breaker, it must be checked and

cleaned. For information on cleaning the motor, see chapter 8. Cleaning.
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 t 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.
Avoid damage to gas or water pipes, electrical cables and load-bearing walls (static).
Connect a FI circuit-breaker with max. release current (30 mA) upstream when using the machine outdoors!
Pull the plug out of the socket before making any adjustments, converting or servicing the machine.
