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 expo-
sed 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 accessory
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 exces-
sive accumulation of powdered metal may cause electrical
hazards.
q) Do not operate the power tool near fl ammable materi-
als. Sparks could ignite these materials.
r) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in electrocu-
tion 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
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 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 accessory. Cor-
ners, 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,
segmented 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 pressure.
Do not attempt to make an excessive depth of cut. Over-
stressing the wheel increases the loading and susceptibility
to twisting or binding of the wheel in the cut and the possibi-
lity 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 pow-
er 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 oc-
cur. Investigate and take corrective action to eliminate the
cause of wheel binding.
h) Do not restart the cutting operation in the workpiece.
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
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.
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
diff erent 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.
WORK ORGANIZATION
Use hearing protection, eye protection, respiratory
protection and (if necessary) gloves. At minimum, use a
class FFP2 half-face particulate mask for respiratory
protection.
Use a dust extractor to keep the workplace clean. To avoid
stirring up dust, do not sweep up dust deposits.

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 securely
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 acciden-
tal 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 applica-
tions. 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 ade-
quately 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 protec-
tion 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
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 diff erent
applications, with diff erent accessories or poorly maintained, the vibration emission may diff er. 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 eff ects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work patterns.
