– The throttle trigger and throttle
trigger lockout must move easily –
throttle trigger must return
automatically to the idle position
when released
– Master control lever can be moved
to STOP or 0
– Check that the spark plug boot is
secure. A loose boot can lead to
flying sparks which may ignite the
escaping fuel/air mixture – risk of
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 concrete cutter
The concrete cutter should only be used
if it is in full working order – risk of
accident!
Starting the engine
Move at least 3 meters away from the
place at which the machine was refueled
and never start the machine in enclosed
spaces.
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 only one
person. There should not be any other
person within the working area, not even
when starting the machine.
Do not drop-start the engine – start as
described in the Instruction Manual.
Before starting, open the shut-off valve
completely and ensure a supply of water
to the diamond abrasive chain – do not
allow diamond abrasive chain to run dry.
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
reliable control, wrap your thumbs tightly
around the handlebar and handle.
The object that is to be cut must be
positioned firmly; always guide the
machine to the workpiece – never vice
versa.
During work
Ensure you always have a firm and safe
footing.
In the event of impending danger or in
an emergency, switch off the engine
immediately by moving the master
control lever to STOPor0.
The machine is operated by only one
person. There should not be any other
person within the working area.
Use extreme caution with openings,
recesses, etc., someone could be
standing behind them – look
beforehand.
Never let the machine run unattended.
When the engine is running: The
diamond abrasive 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!
Never work on a ladder or on any other
unsteady support. Do not work above
shoulder height and never operate the
machine with one hand - risk of
accidents!
Ensure that the working area is clear –
watch out for obstacles, holes and pits.
Do not work alone – keep within calling
distance of others in case help is
needed.
More care and attention than usual are
required when wearing ear protection –
warning sounds (shouts, alarms, etc.)
cannot be heard properly.
Take breaks in due time in order to
prevent tiredness and exhaustion – risk
of accidents!
Keep easily combustible materials away
from hot exhaust gases and hot mufflers
– risk of fire! Mufflers with catalytic
converters can become especially hot.
