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 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.
Do not switch on the machine if tool parts or guard
devices are missing or defective.
Machines with a soft start (indicated by an "X" 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.).
Use elastic cushioning layers if they have been
supplied with the grinding media 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 cutting discs for roughing work! Do not
apply pressure to the side of the cutting 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
14
Specifications for more information on the spindle
length and thread.
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.
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.
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.
