5.6 Starting the engine
Do not start the chains saw until it has been completely
assembled and checked!
IMPORTANT:
- Check that the chain of the chain saw is correctly
tightened.
- CHECK THAT THERE IS OIL IN THE TANK.
- Before starting the machine, make sure that the chain
brake is turned on.
- Get at least 3 m away from the place where you have
refueled the chain saw.
- Make sure that the soil where you are stepping is stable,
and put the chain saw on the soil such that the saw chain
(5) does not touch anything.
- Firmly grasp the rear handle (1) with one hand and hold
the chain saw firmly against the soil. Press the rear
handle (1) with your knee.
Starting the engine: (OLMO 22-400)
- Push the locking button (2) and put switch (15) to position
"ON" at the same time.
- Then release switch (2) again.
- If the chain saw does not start, check the chain brake (4),
pressing backwards if necessary.
- The chain saw will begin to operate at is maximum speed
as soon as it has started.
Switching off:
- Put switch (15) to "OFF".
- Do not lose hold of the machine until it has stopped
completely
5.7. Starting the gasoline models (Fig. 8)
IMPORTANT: The throttle lever (21) is coupled to the
accelerator lever (3). The switch (15) will automatically
return to its position once the accelerator lever (3) has been
pushed.
If the accelerator lever (3) is pushed before the engine is
started, the throttle lever must be set back to the
appropriate position.
Starting the machine
Press the engine start switch putting it, depending on the
model, to position "I" or to the position opposed to "STOP".
Cold machine and warm machine
ALERT: There are two situations for starting: with the
machine cold and with the machine warm. The machine is
considered to be cold when it has been without running for
more than 10 minutes.
The primer bulb
The primer bulb (22) is a small transparent rubber blister at
the machine's outside. The bulb must be filled with gasoline
(with less than 30% air). To fill it, press it several times until
gasoline appears in the transparent button. Once the bulb
has sufficient gasoline, do NOT continue pressing. If you
press more than required, you will not be able to start
because the cylinder has been flooded with gasoline. Thus,
always take into account that the primer bulb should not be
misused.
Do not pull the starter cable more than about
50 cm, and set it back by hand. For efficient
starting, it is important to pull the cable
quickly and strongly. (Fig. 43)

WARNING: If you have pushed the bulb (22) too many
times, or started wrongly, you may have flooded the
cylinder with gasoline.
For starting, pull the starter lever about 8 times with the
switch of the machine switched off and the lever "Choke"
pulled out and deactivated (position "RUN": completely
inserted). Thereafter, switch on the switch and pull to start.
If it does not start, this may be due to a large flooding. In this
situation, you must extract and dry up the spark plug (12)
wet with gasoline before starting. Wait a short while before
again putting in the spark plug (12) to allow the cylinder
become dry from gasoline (Fig. 57, 58 y 59).
