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 manufacturers
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 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.
4.7 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!
Grinding wheels 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 3 and chapter 14. Technical
Specifications for more information on the spindle
length and thread.
During machining, of metals in
particular, conductive dust can form
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
14
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. See chapter 9. Cleaning for more
information on cleaning the motor.
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 loadbearing walls (static).
Pull the plug out of the socket before any making
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.
This power tool is not suitable for polishing work.
Improper use of the machine will void the warranty!
The motor may overheat and damage the electric
power tool. We recommend using our angle
polisher for polishing work.
Secure small workpieces. For example, clamp in a
vice.
Reduce dust exposure:
Particles generated when working with this
machine may contain substances that can
cause cancer, allergic reactions, respiratory
diseases, birth defects or other propagation
defects. Some of these substances include: Lead
(in paint containing lead), mineral dust (from bricks,
concrete etc.), additives used for wood treatment
(chromate, wood preservatives), some wood types
(such as oak or beech dust), metals, asbestos.
The risk depends on for how long the user or nearby
persons are exposed to the substance.
This dust must not be allowed to enter your body.
Do the following to reduce exposure to these
substances: Ensure good ventilation of the
workplace and wear appropriate protective
equipment, such as respirators able to filter
microscopically small 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 less particles enter the
environment in an uncontrolled manner.
Use a suitable extraction unit.
