4M40./4M41 four-cylinder engines
– Turn the decompression levers for cylinders 1,
3 and 4 (counting from the fan end) to posi-
tion „2“ (Figures 15 and 34).
– Turn the decompression lever for cylinder 2 to
position „3“.
Starting procedure
– Turn the starting handle with both hands at an
increasing speed.
The maximum speed of rotation must have been
reached by the time the decompression lever
has returned to position „0“.
– As soon as the engine has started, pull the
starting handle out of the guide sleeve.
– If the engine backfires during starting because
it was not turned over with sufficient force (the
engine could even start to run backwards in
certain circumstances), release the starting
handle immediately and move the speed con-
trol lever to the STOP position (Chapt. 4.3.).
The starting handle could be driven
round by the engine and cause injury.
– Wait until the engine has come to a standstill
before repeating the preparatory procedure
and making another attempt to start it.
4.2.4. Starting with the handle with
kick-back damping
– Preparations for starting the engine and the
hand starting procedure are precisely the
sameas with the standard handle.
Always hold tubular grip „1“ with both hands
(Figures 16 and 17).
– Turn the handle slowly at first, until the pawl
engages in the ratchet, then increase turning
force to build up speed. The highest speed
must have been reached by the time the de-
compression lever returns to position „0“.
As soon as the engine has started, pull the
starting handle out of the guide sleeve.
You must hold the tubular grip firmly
to maintain contact all the time be-
tween the starting handle and the engine.
Maintain turning force during the entire hand
starting operation.
– If backfiring should occur while hand starting
the engine too soft, the brief reversal of move-
ment disengages the pawl between the crank-
shaft „2“ and the drive dog „3“ (Fig. 17).
– If backfiring occured and the engine starts
running backwards (smoke from airfilter),
release crankhandle immediately and move
speed control lever into STOP-position,
chapt. 4.3.
– To repeat the starting attempt, wait for the en-
gine to cease rotating, reset the automatic de-
compression device and turn the starting
handle in the correct starting direction again.
