General Safety Instructions
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!
WARNING – Reading the operating instructions will reduce the risk of
injury.
WARNING Read all safety warnings and instructions. Failure to follow
all safety warnings and instructions may result in electric shock, fire,
and/or serious injury.
Keep all safety instructions and information for future reference.
Pass on your power tool only together with these documents.
Special Safety Instructions
4.1 Safety Warnings Common for Grinding, Sanding, Wire Brushing, or
Abrasive Cutting-Off Operations:
Use
a) 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.
b) Operations such as 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 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.
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) Threaded mounting of accessories must match the grinder spindle thread. For
accessories mounted by flanges, the arbor 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 inspects 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 the application, use a
face shield, safety goggles, or safety glasses. As appropriate, wear a dust
mask, hearing protectors, gloves, and a 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 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 the 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 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 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.
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.
4.2 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 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 the
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 an 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. The accessory may kick
back over your hand.
c) Do not position your body in the area where the power tool will move if
kickback occurs. Kickback will propel the tool in a 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.
4.3 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) The grinding surface of the center 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 and
accidental contact with the wheel and sparks which could ignite clothing.
d) 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.
e) Always use undamaged wheel flanges that are of 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.
f) Do not use worn-down wheels from larger power tools. A wheel intended for a
larger power tool is not suitable for the higher speed of a smaller tool and
may burst.
4.4 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 the 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 kick
back if the power tool is restarted in the workpiece.
e) 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 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.
4.5 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 presents a laceration hazard and may cause snagging,
tearing of the disc, or kickback.
4.6 Safety Warnings Specific for Wire Brushing Operations:
a) Be aware that wire bristles are thrown by the brush even during ordinary
operations. 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 workload and centrifugal forces. 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 3 and
chapter 14. Technical Specifications for more information on the spindle
length and thread. The use of a fixed extractor system is recommended. Always
install an RCD with a max. trip current of 30 mA upstream. If the angle
grinder is shut down via the RCD, it must be checked and cleaned. See chapter
9. Cleaning. Damaged, eccentric or vibrating tools must not be used. Avoid
damage to gas or water pipes, electrical cables, and load-bearing walls
(static). Pull the plug out of the socket before making any adjustments,
converting or servicing the machine. A damaged or cracked additional handle
must be replaced. Never operate a machine with a defective additional handle.
A damaged or cracked safety guard must be replaced. Never operate a machine
with a defective safety guard. Do not switch on the machine if tool parts or
guard devices are missing or defective. Machines with a soft start (indicated
by “WE” in the model designation): An electronic error occurs if the machine
accelerates to maximum speed very quickly when switched on. Other safety-
related electronic functions are no longer available. Have the machine
repaired immediately (see 12.). Secure small workpieces. For example, clamp in
a vice.
Reduce dust exposure:
Some dust created by using this power tool may contain chemicals known to
cause cancer, allergic reaction, respiratory disease, birth defects, or other
reproductive harm. Some examples of these chemicals are: lead from lead-based
paints, crystalline silica from bricks and cement and other masonry products,
Arsenic and chromium from chemically treated lumber, hardwood like oak or
beech, Metals, Asbestos. The risk from these exposures depends on how long you
or bystanders are being exposed. Do not let particles enter the body. To
reduce your exposure to these chemicals: work in a well-ventilated area, and
work with approved safety equipment, such as dust masks that are specially
designed to filter out microscopic particles. Observe the relevant guidelines
for your material, staff, application, and place of application (e.g.
occupational health and safety regulations, disposal). Collect the generated
particles at the source, avoid deposits in the surrounding area. Use suitable
accessories for special work (see chapter 11.), thus fewer particles enter the
environment in an uncontrolled manner. Use a suitable extraction unit. Reduce
dust exposure with the following measures:
– Do not direct the escaping particles and the exhaust air stream at yourself
or nearby persons or on dust deposits.
– Use an extraction unit and/or air purifiers
– Ensure good ventilation of the workplace and keep clean using a vacuum
cleaner Sweeping or blowing stirs up dust
– Vacuum or wash the protective clothing Do not blow, beat or brush

8.2 Working Directions
Grinding:
Press down the machine evenly on the surface and move back and forth so that
the surface of the workpiece does not become too hot.
Rough grinding: position the machine at an angle of 30° – 40° for the best
working results.
Cutting-off operations:
Always work against the run of the disc (see illustration). Otherwise, there
is the danger of the machine kicking back from the cut out of control. Guide
the machine evenly at a speed suitable for the material being processed. Do
not tilt, apply excessive force or sway from side to side.
Sanding:
Press down the machine evenly on the surface and move back and forth so that
the surface of the workpiece does not become too hot.
Wire brushing:**
Press down the machine evenly.
Cleaning
Cleaning the motor: It is possible that particles deposit inside the power tool during operation. This impairs the cooling of the power tool. Conductive build-up can impair the protective insulation of the power tool and cause electrical hazards. The power tool should be cleaned regularly, often, and thoroughly through all front and rear air vents using a vacuum cleaner or by blowing in dry air. Prior to this operation, separate the power tool from the power source and wear protective glasses and a dust mask. Button (9) for adjusting the handle: Occasionally blow compressed air through the button (when pressed, in all 3 main handle positions). Prior to this operation, separate the power tool from the power source and wear protective glasses and a dust mask.
Troubleshooting
Machine with “WE…” in the model designation:
– Overload protection: The electronic signal display (6) lights up and
the load speed decreases dramatically. The motor temperature is too
high! Run the machine in idling until it cools down and the electronic signal
display switches off.
– Overload protection: The electronic signal display (6) lights up and
the load speed decreases slightly. The machine is overloaded. Work with
a reduced load until the electronic signal display goes out.
– Electronic safety stop: The electronic signal display (6) lights up
and the machine was SWITCHED OFF automatically. If the slew rate of the
current is too high (for example, if the machine suddenly seizes or kickback
occurs), the machine switches off. Switch off the machine at the trigger
switch (8). Switch it on again and continue to work as normal. Try to prevent
the machine from seizing. See Section 4.2.
– Restart protection: The electronic signal display (6) FLASHES and the
machine does not start. The restart protection is active. If the mains
plug is inserted with the machine switched on, or if the power supply is
restored following an interruption, the machine does not startup. Switch the
machine off and on again.
– When switched on, the machine accelerates to maximum speed very
quickly, i.e. automatic restriction of the starting current does not work
(soft start). An electronic error exists. Other safety-related electronic
functions are no longer available. Have the machine repaired immediately (see
12.).

Emission values
**** These values make it possible to assess the emissions from the power
tool and to compare different power tools. Depending on the operating
conditions, the condition of the power tool or the accessories, the actual
load may be higher or lower. For assessment purposes, please allow for breaks
and periods when the load is lower. Based on the adjusted estimates, arrange
protective measures for the user e.g. organizational measures.
Vibration total value (vector sum of three directions) determined in
accordance with EN 60745:
ah, SG = Vibration emission value (surface grinding)
ah, DS = Vibration emission value (disc sanding)
Oh,SG/DS = Uncertainty (vibration)
Typical A-effective perceived sound levels:
LpA =Sound-pressure level
LAW = Acoustic power level
