– Do not allow the guide bar to
become jammed
– Always be aware that the object to
be cut may move and other factors
may cause the cut to close and jam
the diamond abrasive chain
– The object to be cut must be
secured and supported so that the
cut remains open during and after
cutting
– Do not twist the guide bar in the cut
Working – abrasive cutting
Ensure sufficient water supply to
diamond abrasive chain – do not allow
diamond abrasive chain to run dry.
Always wet cut – regardless of the
material to be cut.
The diamond abrasive chain must be
guided straight in the cut, without
wedging. Never exert lateral pressure on
the diamond abrasive chain.
Do not use the diamond abrasive chain
for lateral grinding or scrubbing.
Do not use the starting throttle position
for cutting. Engine speed cannot be
controlled with the throttle trigger in this
position.
Examine the workplace. Avoid all
danger due to damaged piping or
electrical wiring.
The machine must not be used near
inflammable substances or gases.
Never use the machine to cut inside
pipes, metal troughs or other containers
unless you are absolutely sure that they
do not contain any volatile or
inflammable substances.
Never leave the machine unattended
with the engine running. Switch off the
engine before leaving the machine
(e. g., for a break).
Work calmly and methodically – only
with good lighting and visibility. Do not
endanger others – stay alert at all times.
Make certain that all parts of your body
are well clear of the extended range of
travel of the diamond abrasive chain.
Only pull concrete cutter out of the
object being cut with the diamond
abrasive chain running.
Only use concrete cutter for cutting – not
for prying or shoveling away objects.
Always decide the cutting direction
before positioning the concrete cutter.
After that, do not change the cutting
direction. Avoid knocks and bumps with
the machine while in the cut – do not
drop the machine into the cut – danger of
breakage!
If cutting performance begins to
deteriorate, check the sharpness of the
diamond abrasive chain, resharpen as
needed. To do this, briefly cut through
abrasive material, e. g., sandstone,
aerated concrete or asphalt.
When working above ground level:
– Always use a lift bucket
– Never use the machine while
standing on a ladder
– Never use the machine in unsteady
locations
– Never cut above shoulder height
– Never use the machine with one
hand
Begin cutting with the concrete cutter at
full throttle.
At the end of the cut, the concrete cutter
is no longer supported by the cutting
attachment in the cut. The machine's
weight must be borne by the user – risk
of loss of control!
Keep water and sludge away from
electric cables - risk of electric shocks!
Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands (whitefinger
disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
