Starting the engine
- Move at least 3m away from the place where you fuelled
the saw.
- Make sure you have a good footing, and place the saw
on the ground in such a way that the chain is not touching
anything.
- Engage the chain brake (lock).
- Hold the tubular handle tightly with one hand and press the
chain saw to the ground.
- Steady the rear handle by standing in the hand guard.

109 HappyStart
Cold-starting
The carburetors of these saws have a choke valve for cold
starting (mixture enrichment).
To make it easier to start, the chain saw 109 HappyStart is
equipped with a semi-automatic starting valve (B/5). Pushing this
valve in reduces the amount of compression effort needed, so that
it is easier to bring the engine up to starting speed when pulling
the starter cable. The high pressure increase in the combustion
chamber that results from the Þ rst ignitions will automatically
close the starting valve (button pops back out).
Models 109, 111, 115 and 115 H do not have a starting
valve. Starting and carburetor adjustment are as for model
109 HappyStart except without the instruction "Push the
starting valve".
Pull the choke (B/1) out until it audibly clicks. This simulta-
neously actuates the half-throttle lock.
Put the short-circuiting switch (B/2) in position "I" (START).
Slowly pull out the starter cable (B/3) until you notice resistance
(the piston is positioned before the top dead centre).
Push the starting valve (B/5) (only 109 HappyStart).
Now pull the starter cable with a fast and forceful movement
until you hear the Þ rst ignition.
CAUTION: Do not pull out the starter cable more than approx.
50 cm, and lead it back by hand.
When you hear the Þ rst ignition, push the choke (B/1) in.
Push the starting valve again (only 109 HappyStart) and pull
the starter cable.
As soon as the engine is running, grasp the rear handle (this
actuates the grip safety (B/6)) and tap the throttle (B/4). This will
release the half-throttle lock and the engine will run in idle.
CAUTION: As soon as the engine is started it must be put
in idle to prevent the chain brake from being damaged.
Now release the chain brake.
Warm starting
As described for cold starting, except before starting pull the
choke (B/1) all the way out and back in one time, in order to
activate the half-throttle lock.
If the engine doesn’t start after 2 or 3 pulls, repeat the entire
starting procedure as described for cold starting.
Stopping the engine
Put the short-circuiting switch (B/2) in position "O" (STOP).
