2 Safety Precautions and Working Techniques
– Check the chain sprocket
– Sprocket nose moves easily
– Correctly mounted guide bar
– The diamond abrasive chain must be suitable
for the material to be cut. It must be in good
condition and fitted correctly (direction of run‐
ning)
– Correctly tensioned diamond abrasive chain
– Smooth action of throttle trigger and throttle
trigger lockout – throttle trigger must return
automatically to idle position
– Master control lever can be moved to STOP or
0
– Check that the spark plug boot is secure – a
loose boot may cause arcing that could ignite
combustible fumes and cause a fire!
– Never attempt to modify the controls or safety
devices
– Keep the handles dry and clean, free from oil
and dirt – important for safe control of the con‐
crete cutter
The concrete cutter should only be used if it is in
full working order – risk of accident!
2.6 Starting the engine
Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.
The machine may only be used on level ground.
Ensure a firm and secure footing and hold the
machine firmly. The diamond abrasive chain
must not touch any objects or the ground and
must not be in the cut, because it may begin to
rotate when the machine is started.
The machine is operated by a single person only
– do not allow any person to stay within the work‐
ing area – nor with starting.
Do not drop-start the power tool – start the
engine as described in the user manual.
Before starting, open the shut-off valve com‐
pletely and ensure a supply of water to the dia‐
mond abrasive chain – do not allow diamond
abrasive chain to run dry.

2.7 Holding and guiding the
machine
Always hold the machine firmly with both hands:
Right hand on the rear handle – even if you are
left-handed. To ensure safe control, wrap your
fingers tightly around both handles.
The object to be cut off has to be firmly suppor‐
ted. Always guide the machine towards the work‐
piece – never the other way round.
2.8 While working
Make sure you always have good balance and
secure footing.
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by mov‐
ing the master control lever to STOPor0.
Your power tool is designed to be operated by
one person only. Do not allow other persons in
the work area.
Use extreme caution with openings, recesses,
etc., someone could be standing behind them –
look beforehand.
Never leave a running machine unattended.
When the engine is running: The diamond abra‐
sive chain continues to run for some time after
the throttle trigger has been released – Risk of
injury due to coasting effect!
Beware of slipping on ice, water, snow or uneven
ground!
Don not work while standing on a ladder – not on
an insecure support – not over your shoulder
height – not with one hand only – risk of accident!
Keep clear the working area – bear in mind
obstacles, holes and pitches.
Do not work alone – keep within calling distance
of others in case help is needed.
