– 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 – cutting off
Ensure sufficient water supply to
diamond abrasive chain – do not allow
diamond abrasive chain to run dry.
Always make wet cuts – 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 for lateral grinding or
scrubbing.
Do not operate your saw with the
starting throttle lock engaged. 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.
Do not cut into pipes, metal tanks or
other containers if you are not sure that
they do not contain any volatile or
inflammable substances.
Never leave the machine unattended
with the engine running. Stop the engine
before leaving the machine unattended
(e. g. for breaks).
Work calmly and carefully – in daylight
conditions and only when visibility is
good. Ensure you 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.
The diamond abrasive chain must be
running when you pull the concrete
cutter out of the object being cut.
Only use the concrete cutter for cutting –
not for prying off or shoveling away
objects.
Always decide the cutting direction
before positioning the concrete cutter.
After that, do not change the cutting
direction. Never push or hit with the
device into the cutting gap – do not let
the concrete cutter fall into the cutting
depth – risk 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 at heights:
– Always use a lift bucket
– Never use the machine while
standing on a ladder
– Never work on an insecure support
– Never work above shoulder height
– Never use the machine with just 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 user must
bear the weight of the machine – risk of
loss of control!
Keep water and sludge away from alive
electrical cables – risk of electric shock!
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.
