Safety Warnings Specific For Sanding Operations - Metabo W 750-100 Original Instructions Manual

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 it 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 re-enter the cut. The wheel may bind,
walk up or kickback 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.
g) Do not attempt to do curved cutting.
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, which can lead to serious injury.
4.5 Safety warnings specific for sanding
operations:
a) Use proper sized sanding disc paper. Follow
the manufacturer's recommendations, when
selecting sanding paper. Larger sanding paper
extending too far 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 specified 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.
Wear ear protectors.
WARNING – Always operate the power tool
with two hands.
Do not use the guard for cutting-off
operations. When working with cut-off
wheels, always use the parting safety guard
for safety reasons.
Do not use any segmented diamond cut-off wheels
with segment slits >10 mm. Only negative segment
cutting angles are permitted.
Use bonded cut-off wheels only if these are
reinforced.
Use elastic cushioning layers if they have been
supplied with the sanding media and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect wheels from grease or
impact!
Accessories must be stored and handled with care
in accordance with the manufacturer's instructions.
Never use cut-off wheels for roughing work or
deburring! Do not apply pressure to the side of the
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.
Use of a suitable fixed extractor system is
recommended. Always install an RCD with a
maximum trip current of 30 mA upstream. If the
angle grinder is shut down via the GFCI, 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 (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.
