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 wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool 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 work-
piece. 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 work-
piece.
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 pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
5.6 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.
5.7 Additional safety precautions
5.7.1 Personal safety
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
c) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
d) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
e) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotat-
ing insert tools, may lead to injury.
f) Always lead the supply cord and extension cord
away from the power tool to the rear while work-
ing. This helps to avoid tripping over the cord while
working.
g) Children must be instructed not to play with the
power tool.
h) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
i) WARNING: Some dust created by grinding, sand-
ing, cutting and drilling contains chemicals known
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res-
piratory or other injury. Some examples of these
chemicals are: lead from lead-based paints, crys-
talline silica from bricks, concrete and other masonry
products and natural stone, 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 exposure to these
chemicals, the operator and bystanders should
work in a well-ventilated area, work with ap-
proved safety equipment, such as respiratory pro-
tection appropriate for the type of dust generated,
and designed to filter out microscopic particles
and direct dust away from the face and body.
Avoid prolonged contact with dust. Wear protec-
tive clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth,
eyes, or to remain on your skin may promote absorp-
tion of harmful chemicals.
5.7.2 Tool Use and Care
a) Grinding discs must be stored and handled care-
fully in accordance with the manufacturer's in-
structions.
b) Check that the grinding disc is fitted in accor-
dance with the manufacturer's instructions.
c) If use of a spacer ring or other intermediate part is
specified and the part is supplied with the grinding
disc, check to ensure that the part is fitted.
d) Never use the power tool without the guard.
e) The workpiece must be fixed securely in place.
f) Do not use cutting discs for grinding.
g) After disc breakage, or if the power tool is
dropped, falls or suffers other mechanical
damage, it must be checked at a Hilti Service
Center.
h) Take steps to ensure that flying sparks from the
power tool do not present a hazard, i.e. by striking
yourself, other persons or inflammable materials.
Adjust the position of the guard accordingly.
In case of an interruption in the electric supply:
i)
Switch the power tool off and unplug the supply
cord. This will prevent accidental restarting when the
electric power returns.
