WARNING
The vibration emission level given in this information sheet has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of
exposure.
The declared vibration emission level represents the main applications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained, the vibration emission may differ. This may signifi cantly
increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may signifi cantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work patterns.
WARNING! Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fi re and/or serious
injury.
Save all warnings and instructions for future
reference.

CUT-OFF MACHINE SAFETY WARNINGS

a) The guard provided with the tool must be secu-
rely attached to the power tool and positioned for
maximum safety, so the least amount of wheel is
exposed towards the operator. Position yourself and
bystanders away from the plane of the rotating wheel.
The guard helps to protect operator from broken wheel
fragments and accidental contact with wheel.
b) Use only bonded reinforced or diamond cut-off
wheels for your power tool. Just because an accessory
can be attached to your power tool, it does not assure
safe operation.
c) The rated speed of the accessory must be at least
equal to the maximum speed marked on the power
tool. Accessories running faster than their rated speed
can break and fl y apart.
d) Wheels must be used only for recommended
applications. For example: do not grind with the side
of cut-off wheel. Abrasive cut-off wheels are intended for

peripheral grinding, side forces applied to these wheels
may cause them to shatter.
e) Always use undamaged wheel fl anges that are of
correct diameter for your selected wheel. Proper wheel
fl anges support the wheel thus reducing the possibility of
wheel breakage.
f) Do not use worn down reinforced wheels from
larger power tools. Wheels intended for a larger power
tool are not suitable for the higher speed of a smaller tool
and may burst.
g) The outside diameter and the thickness of your
accessory must be within the capacity rating of your
power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
h) The arbour size of wheels and fl anges must
properly fi t the spindle of the power tool. Wheels and
fl anges with arbour holes that do not match the mounting
hardware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
i) Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If power tool
or wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing the
wheel, position yourself and bystanders away from
the plane of the rotating wheel and run the power tool
at maximum no load speed for one minute. Damaged
wheels will normally break apart during this test time.
j) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and shop apron capable
of stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping fl ying
debris generated by various operations. The dust mask or
respirator must be capable of fi ltrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearing loss.
k) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear per-
sonal protective equipment. Fragments of workpiece or
of a broken wheel may fl y away and cause injury beyond
immediate area of operation.
l) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a „live" wire may make
exposed metal parts of the power tool „live" and could give
the operator an electric shock.
m) Position the cord clear of the spinning accessory. If
you lose control, the cord may be cut or snagged and your
hand or arm may be pulled into the spinning accessory.
n) Never lay the power tool down until the accesso-
ry has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of your
control.
o) Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory could
snag your clothing, pulling the accessory into your body.
p) Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
q) Do not operate the power tool near fl ammable
materials. Sparks could ignite these materials.
r) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in electro-
cution or shock.

operations
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid stalling
of the rotating wheel which in turn causes the uncontrolled
power tool to be forced in the direction opposite of the
wheel's rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched
by the workpiece, the edge of the wheel that is entering
into the pinch point can dig into the surface of the material
causing the wheel to climb out or kick out. The wheel may
either jump toward or away from the operator, depending
on direction of the wheel's movement at the point of
pinching. 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 fi rm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. Always use auxiliary handle, if provided, for
maximum control over kickback or torque reaction du-
ring 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 in line with the rotating
wheel. Kickback will propel the tool in 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 acces-
sory. Corners, sharp edges or bouncing have a tendency
to snag the rotating accessory and cause loss of control
or kickback.
e) Do not attach a saw chain, woodcarving blade, seg-
mented diamond wheel with a peripheral gap greater
than 10 mm or toothed saw blade. Such blades create
frequent kickback and loss of control.
f) Do not "jam" the wheel or apply excessive pres-
sure. Do not attempt to make an excessive depth of
cut. Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
g) 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 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.
h) Do not restart the cutting operation in the workpi-
ece. 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 workpiece.
i) Support panels or any oversized workpiece to mi-
nimize 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.
WALL CHASER & DUST EXTRACTOR TOOL SYSTEM
Use only dust extractors for dust class M with the wall
chaser. Dust capture and separation may not be as good
with other combinations.
Observe the instructions for operating, maintaining and
cleaning the dust extractor, including the fi lters. Empty the
dust container immediately when it becomes full.
Use only the designated suction hose. Do not modify the
suction hose. If masonry chunks enter the suction hose,
stop work and clear the suction hose immediately. Avoid
kinking the suction hose.
Clean and exchange fi lters regularly. Do not remove any
fi lters or fi lter components.
Select wall chasers and cutting discs to suit the substrate
material. Various types of cutting disc are available for
different substrates.
Use only diamond-tipped cutting discs. Segmented
diamond discs may only be used if they have negative
rake and the gap between segments is no wider than
10 mm.
Replace or resharpen cutting discs promptly whenever
necessary. When cutting performance decreases, check
whether the cutting discs are worn and need to be
replaced or resharpened.
Start and continue grooves as described in the operating
instructions.

WORKPLACE

Ensure compliance with the general requirements for
construction work sites (provide adequate lighting, avoid
fall hazards, etc.). Follow safety instructions.
Ensure good ventilation.
Keep the work area clear and unobstructed. With relatively
long grooves, the dust extractor must be able to move
freely with the chaser and/or travel directly after it.
