a) Do not "jam" the cut-off wheel or apply ex-
cessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twist-
ing or binding of the wheel in the cut and the
possibility of kickback or wheel breakage.
b) Do not position your body in line with and behind
en
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 care-
fully reenter 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 kick-
back. 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 kick-
back.
5.2.5 Additional safety instructions for wire
brushing operations
Safety warnings specific for wire brushing opera-
tions:
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.

5.2.6 Personal safety
a) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
b) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
c) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
d) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially
rotating insert tools, may lead to injury.
e) Always lead the supply cord and extension cord
away from the power tool to the rear while
working. This helps to avoid tripping over the
cord while working.
f) When grinding with straight grinding discs and
cutting with cutting discs in metalworking ap-
plications, use only the guard with cover plate.
This is available as an optional accessory.
g) Do not use the power tool if it starts with a
jolt.This may be an indication that the electronic
control unit is defective. Have the tool repaired at
an authorized Hilti service center right away.
h) Children must be instructed not to play with the
power tool.
i) The power tool is not intended for use by chil-
dren, by debilitated persons or those who have
received no instruction or training.
j) 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. To achieve a high level of dust
collection, use a suitable vacuum cleaner of the
type recommended by Hilti for wood dust and/or
mineral dust together with this tool. Ensure that
the workplace is 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.
