■
Thrashing hoses can cause serious injury. There-
fore, always check that the hoses and their fix-
ings are not damaged or have not come loose.
■
If universal rotary joints (claw couplings) are
used, locking pins must be used to provide pro-
tection; Whipcheck® air hose restraints must be
used to provide protection in case of a failure of
the connection of the hose to the machine.
■
Ensure that the maximum permissible pressure
on the machine is not exceeded.
■
Never carry compressed-air-powered machines
by the hose.
Special safety instructions for
grinding and abrasive cutting
■
Only use the grinding tools approved for your
compressed air tool and the blade guard provid-
ed for these grinding tools. Grinding tools which
are not intended for the compressed air tool
cannot be adequately shielded and are unsafe.
■
Offset grinding discs must be mounted in such
a way that their grinding surface does not
project above the plane of the blade guard
edge.
An improperly fitted grinding disc which
protrudes over the level of the blade guard
edge cannot be properly guarded.
■
The blade guard must be securely attached
to the compressed air tool and adjusted for
maximum safety so that the minimum possible
amount of the abrasive medium is open to the
operator.
The blade guard is designed to pro-
tect the operator from fragments and accidental
contact with the grinding tool.
■
Grinding tools should only be used for the
recommended applications. For example:
Never grind with the side surface of a cutting
disc.
Cutting discs are designed to remove
material with the edge of the disc. Any lateral
application of force on these grinding tools can
lead to a breakage.
■
Always use undamaged clamping flanges of
the correct size and shape for the grinding
wheel you have selected.
Suitable flanges
support the grinding disc and reduce the risk of
a disc breakage. Flanges for cutting discs can
be different to flanges for other grinding discs.
■
Do not use worn grinding wheels from larger
pneumatic tools.
Grinding wheels for larger
compressed air tools are not designed for the
higher speeds of smaller compressed air tools
and may break.
Additional special safety instructions
for abrasive cutting
■
Avoid blocking the cutting disc or excessive
contact pressure. Do not make any exces-
sively deep cuts.
Overloading the cutting disc
increases the stress and likelihood of tilting or
blocking and thus the possibility of a setback or
a breakage of the grinding tool.
■
Avoid the area in front of and behind the
rotating cutting disc.
When you move the cut-
ting disc away from yourself in the workpiece it
is possible that, in the event of a kickback, the
compressed air tool might be thrown out direct-
ly towards you along with the rotating disc.
■
If the cutting disc jams or you stop working,
switch the tool off and hold it steady until the
disc has completely stopped turning. Never
attempt to pull a rotating cutting disc out of a
cut. This could lead to a kickback.
Identify and
remove the cause of the jam.
■
Do not switch the power tool back on as long
as it is in the workpiece. Allow the cutting disc
to reach its full speed before you carefully
continue the cut.
Otherwise, the disc can jam,
jump out of the workpiece or cause a kickback.
■
Support panels or large workpieces to re-
duce the risk of the cutting disc jamming and
causing a kickback.
Large workpieces can
bend under their own weight. The workpiece
must be supported on both sides of the disc:
both in the vicinity of the cutting disc and also
at the edge.
■
Cutting discs must be stored and handled care-
fully and in accordance with the manufacturer’s
instructions.
