parts of the power tool "live" and could give the
operator an electric shock.
l) Position the cord clear of the spinning
accessory. If you lose control of the tool, the cord
may be cut or snagged and your hand or arm may
be pulled into the spinning accessory.
m) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grab the surface and pull
the power tool out of your control.
n) Do not carry the power tool while it is running. Your clothing could become caught
accidentally in the rotating cutting accessory, and
this accessory could then drill into your body.
o) Regularly clean the ventilation slots on your
power tool. The motor's fan will draw the dust
inside the housing and excessive accumulation of
powdered metal may cause electrical hazards.
p) Do not operate the power tool near
flammable materials. Sparks could ignite these
materials.
q) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
4.2 Kickback and Related Warnings
WARNING – Always wear protective
goggles.
Kickback is the sudden response to an abrasive
wheel that is jamming while rotating. Jamming
causes the rotating accessory to stop abruptly,
which in turn causes the uncontrolled power tool to
be forced in the direction opposite to the
accessory's rotation at the point of jamming.
For example, if an abrasive wheel jams in the
workpiece, the edge of the wheel entering into the
workpiece can snag, thus causing either kickback
or the wheel to break off. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use additional
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or
kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body either before or
behind the rotating wheel. Kickback will propel
the tool in the direction opposite to the wheel's
movement at the point of snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or bouncing
12
have a tendency to snag the rotating accessory and
cause loss of control or kickback.
e) Do not use a chainsaw blade, toothed saw
blade or segmented diamond disc with slots
wider than 10 mm. Such blades create frequent
kickback and loss of control.
f) Do not "jam" the cut-off wheel or apply
excessive pressure. Do not attempt to make an
excessive depth of cut. Overstressing the wheel
increases the loading and susceptibility to twisting
or jamming of the wheel in the cut and the possibility
of kickback or wheel breakage.
g) If the wheel gets jammed or you interrupt
operation for any reason, switch off the power
tool and hold the power tool still 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 jamming.
h) Do not restart the tool while in the workpiece.
Let the wheel reach full speed and carefully
reenter the cut. The wheel may bind, walk up or
kickback if the power tool is restarted in the
workpiece.
i) 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.
j) 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.
4.3 Additional Safety Instructions
Ensure that the spot where you wish to work is free
of power cables, gas lines or water pipes (e.g. using
a metal detector).
Always use the additional side handle provided
when working with the wall chaser (9).
The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must
be sufficiently supported.
The diamond cutting blades must fit without play in
relation to the support flange. Do not use adapters
or reducers.
Diamond cutting blades must be stored and
handled with care in accordance with the
manufacturer's instructions.
Ensure that the diamond cutting blades are installed
in accordance with the manufacturer's instructions.
Never switch on the machine without the protective
cover installed.
Ensure that sparks produced during work do not
constitute a risk to the user or other personnel and
are not able to ignite inflammable substances.
Endangered areas must be protected with flame-
resistant covers. Make sure that fire-risk areas are
always provided with suitable fire extinguishers.
