3.8 Functional parts for starting up the chainsaw
Primer (21)
On delivery, after extended periods in which the chain saw
has not been used and if the tank has been run completely
dry there will be no fuel mixture in the carburettor
immediately after refuelling.
In order to make it easier to start the chainsaw under these
circumstances, press the primer repeatedly (at least 5x) to
pump fuel mixture into the carburettor.
Any excess fuel mixture pumped into the carburettor is
automatically flushed back into the tank.
Not always standard, depending on the version: Decompression valve (22a / 22b)
When the decompression valve is depressed, the compression pressure in the combustion chamber
is reduced. This means that the engine offers less resistance during start-up, which makes it
noticeably easier to start the engine. When the cable is pulled the decompression valve automatically
jumps back to the normal position. If you need to pull the starter cable more than once to start the
engine (e.g. during a cold start), press the decompression valve again each time.
Starter handle (17) and starter cable
The following instructions are intended to extend the service life of the starter mechanism:
• To start the engine, first pull the starter handle carefully until a first resistance is felt (top dead
centre point of the piston), and then pull it through in a fast and strong motion.
• Always pull the cable in a straight direction.
• Do not allow the cable to chafe on the edge of the cable eyelet.
• Avoid pulling the cable all the way out - risk of breaking the cable.
• Always guide the starter handle back to its starting position - do not just let go and allow it to
speed back by itself.
A damaged starter cable can be replaced by a specialist.
Choke lever (7) and part throttle control pin (8) ! part throttle setting
The choke lever is pulled out
(7) to close the starter flap
on the carburettor (cold start
setting).
This also activates the part
throttle setting at the same
time, which can be seen
from the pulled-out part
throttle control pin (8)
When the choke lever is pushed back in
(the starter flap on the carburettor is
open) the part throttle setting remains
active – this can be seen from the part
throttle control pin (8), which is still
pulled out.
Operate the throttle control to cancel
the part throttle setting.
! The part throttle control pin (8) jumps
back into place.
This applies both when the engine is
running and when it is switched off.
