Control, maintenance and service of
the machine's safety equipment
1. Throttle trigger
lock
• Check that the throttle is
locked in the "idling
position" when the
throttle trigger lock is in
its original position.
• Press in the throttle
trigger lock and make
sure it returns to its
original position when
released.
• Ensure that the throttle
and throttle trigger lock
move easily and that their
return spring systems
function.
• See section "Start". Start
the machine and apply
full throttle. Release the
throttle and check that
the cutting equipment
stops and remains at a
standstill. If the cutting
equipment rotates with
the throttle in the idling
position then the
carburettor's idling setting
must be checked. See
chapter "Main-tenance".
2. Stop switch
• Start the engine and make
sure that the engine stops
when the stop switch is
moved to the stop
position.
SAFETY INSTRUCTIONS
IMPORTANT INFORMATION
• All service and repairs to the machine require
special training.
• This applies especially to the machine's safety
equipment. If the machine does not meet any of
the controls listed below you should contact
your service workshop.
• The purchase of one of our products guarantees
that professional repair and servicing will be
carried out on it. If the point of purchase is not
one of our servicing dealers, please ask for
details of the closest service workshop.
3. Vibration damp-
ing system
• Check the vibration
damping elements
regularly for material
cracks and distortion.
• Check that the vibration
damping elements are
securely attached between
the engine unit and the
harness.
4. Silencer
• Never use a machine that
has a defective silencer.
• Check regularly that the
silencer is secure.
• If the silencer is fitted
with a spark arrest screen
then it should be cleaned
regularly. A blocked
screen leads to the engine
overheating with serious
damage as a result. Never
use a silencer with a
defective spark arrest
screen.
