Safety Warnings Specific For Wire Brushing Operations - Metabo W 750-100 Manual Original

back. Large workpieces tend to sag under their own
weight. Supports must be placed under the work-
piece 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, elec-
trical wiring or objects that can cause kickback.
4.5 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.
4.6 Safety Warnings Specific for Wire Brush-
ing 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 safety 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 grinding media and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect discs from grease or impact!
Grinding wheels must be stored and handled with
care in accordance with the manufacturer's
instructions.
Never use cut-off wheels for roughing work! Do not
apply pressure to the side of cut-off wheels.
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 sanding 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 the 14. Technical Specifications
chapter for more information on the spindle length
and thread.
It is recommended to use a stationary extraction
system and to place a ground fault circuit interrupter
(GFCI) downstream. If the angle grinder is shut
down via the GFCI, it must be checked and cleaned.
See the 9. Cleaning chapter for more information on
cleaning the motor.
Damaged, eccentric or vibrating tools must not be
used.
Avoid damage to gas or water pipes, electrical
cables and load-bearing walls (building structure).
Pull the plug out of the socket before making any
adjustments, converting or servicing the machine.
Metabo S-automatic safety clutch (WQ 1100-125,
WEQ 1400-125 only). When the safety clutch
activates, switch off the machine immediately!
A damaged or cracked additional handle must be
replaced. Never operate the 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 by clamping
them in a vice.
Reducing dust exposure:
WARNING - Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, 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, and
- Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are
specially designed to filter out microscopic
particles.
This also applies to dust from other materials such
as some timber types (like oak or beech dust),
metals, asbestos. Other known diseases are e.g.
allergic reactions, respiratory diseases. Do not let
dust enter the body.
Observe the relevant guidelines and national
regulations for your material, staff, application and
place of application (e.g. occupational health and
safety regulations, disposal).
Collect the particles generated at the source, avoid
deposits in the surrounding area.
Use suitable accessories for special work. In this
way, 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,
