Safety Warnings Specific For Sanding Operations - Metabo W 22-180 Manual Del Usuario

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.
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 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
14
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.
It is recommended to use a stationary extraction
system and to place a ground fault circuit interrupter
(GFCI) downstream. 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.
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 that generate dusts or vapours that may
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 loadbearing 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.
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 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.).
