SAFETY INSTRUCTIONS FOR ABRASIVE
CUTTING APPLIANCES
FURTHER SAFETY INSTRUCTIONS FOR
ABRASIVE CUTTING APPLICATIONS
a) The upper guard, which is a part of the power tool, must be
attached securely and set in a way that ensures maximum
safety, i.e. the smallest possible amount of the grinding tool is
exposed to the operator. Ensure that you and anyone else in
the vicinity remain outside of the range of the rotating
grinding disc. The upper guard is designed to protect the
operator from fragments and accidental contact with the
grinding tool.
b) Use only diamond-coated cutting discs for your power tool.
Just because you can attach the accessories to your power
tool, does not ensure they are safe to use.
c) The maximum speed of the accessory tool used must be at
least as high as the maximum speed specified for the power
tool. Accessories which rotate faster than the maximum
permissible rate can break and throw pieces into the air.
d) Grinding tools should on!/ be used for the recommended
applications. For example: Never grind with the side surface
of a citing 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 breakage.
e) Always use an undamaged clamping flange of the correct
size and shape for the selected grinding disc. Suitable
Ranges support the grinding disc and reduce the risk of disc
breakage.
f) Do not use worn grinding discs from larger power tools.
Grinding discs for larger power tools are not designed for the
higher rotational speeds of smaller power tools and can
break.
g) The external diameter and thickness of the accessory tool
used must comply with the dimensions of your power tool.
Incorrectly dimensioned accessory tools cannot be
sufficiently shielded or controlled.
h) Grinding discs and flanges must fit precisely onto the grinding
spindle of your power tool. Accessory tools which do not fit
precisely on the grinding spindle of the power tool will rotate
unevenly, vibrate severely and can lead to a loss of control.
i) Do not use damaged grinding discs. Check the grinding discs
before each use for chips and cracks. If the power tool or
grinding disc is dropped, check to see if it either are dam>
aged, or use an undamaged grinding disc. After checking and
inserting the grinding disc, ensure that you and any other
people in the vicinity remain outside of the range of the
rotating grinding disc, and allow the tool to rotate at maximum
speed for one minute. Damaged grinding discs usually break
during this test period.
j) Wear personal protective equipment. Depending on the
application, ensure that you use full face protection, eye
protection or goggles. If required, use a dust mask, ear
protectors, protective gloves or special apron particles. Eyes
should be protected from flying debris that may be generated
during certain applications. Dust or filter masks must filter any
dust created by ^he application. If you are exposed to loud
noise for any length of time, you can suffer a hearing loss.
k) Ensure that other people remain at a safe distance to your
workspace. Anyone who enters the workspace must wear
personal protective equipment. Fragments of the workpiece
or broken accessory tools can fly off and cause injury -even
outside the immediate working area.
l) Hold power tool by the insulated gripping surfaces when
performing an operation where the accessory tool may
contact hidden wiring or its own cord. Contact with a "live"
wire may make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
m) Keep the power cord away from any Totaling accessories. If
you lose control of the appliance, the cord may get cut or
caught and your hand or arm could get caught in the rotating
accessory tool.
n) Never put the power tool down until the accessory tool has
com» to a complete standstill. The rotating accessory tool
could come into contact with
出
e surface and cause you to
lose control of the power tool.
o) Do not leave the power fool running while carrying it.
Accidental contact between your clothing and the rotating
accessory tool could cause your clothing to get caught and
the accessory tool to penetrate a part of your body.
p) Clean the ventilation slits of your power fool regularly. The
engine fan draws dust into the housing and a strong
accumulation of metal dust can cause electrical hazards.
q) Do not use the power tool in the vicinity of flammable
materials. Sparks can ignite such materials.
r) Do not use any accessory tools which require liquid coolant.
The use of water or other liquid coolants may lead to electric
shock.
Kickback and corresponding safety instructions
Kickback - causes and corresponding safety instructions
• Kickback is a sudden reaction caused when o rotating
grinding disc catches or jams. Catching or jamming causes
the rotating accessory tool to stop abruptly. If this happens,
on uncontrolled power tool turns rapidly against the direction
of rotation of the accessory tool caught in the blockage.
• If for example, a grinding disc catches or jams, the edge of
the grinding disc that is projecting into the workpiece can get
caught and break off the grinding disc or cause a kickback.
The grinding disc can then fly in the direction of the operator
or away from him, depending on the direction of rotation of
the disc at the blockage. This can also break grinding discs.
a) Hold the power tool firmly in both hands and position your
arms so they can absorb the force of a kickback. Always use
the auxiliary handle, if available, so you have the maximum
control over the kickback force or reaction torques at full
speed. By taking adequate precautions, the operator con stay
in control of the kickback and reaction torques.
b) Never hold your hand close to a rotating accessory tool. The
accessory tool could hit your hand in the case of a kickback.
c) Avoid the area in front of and behind the rotating cutting disc.
The kickback will force the power tool in the opposite
direction to the direction of rotation of the grinding disc at the
blockage.
d) Take special care when working around corners, sharp
edges, etc. Avoid allowing the accessory tool to bounce back
from the workpiece or jam. The rotating accessory tool it
more likely to jam in corners or sharp edges or if it bounces.
This can cause a loss of control or kickback.
A kickback is caused by incorrect use or misuse of the power
tool. This can be avoided by taking proper precautions as given
below
