Chainsaw Oil; Refueling; Starting The Motor; Starting The Gasoline Models - stayer OLMO G1-250 Operating Instructions Manual

Fuel mixture
The chain saw engine is a highly efficient 2-stroke engine. It
runs with a mixture of gasoline and oil for 2-stroke engines.
The engine has been designed run with unleaded regular
gasoline having at least 95 octanes. Should such a fuel not
be available, you may use a higher octane fuel. This will not
affect the engine.
To achieve optimal engine performance and to protect
your health and environment, use unleaded gasoline only.
To lubricate the engine, use 2-stroke engine oil (quality
rating: JASO, FC, ISO, EGO) that is added to the gasoline.
Do not use ready-mixed fuel from fuel stations.
The correct proportion of the mixture is:
25:1 i.e. 25 parts of gasoline and 1 part of oil.
5.4 Saw chain oil
Use oil with an adhesive additive to lubricate the chain and
the guide bar. The adhesive additive prevents the oil falling
from the chain too quickly.
We recommend using saw chain oil that is biodegradable to
protect the environment. The use of biodegradable oil may
even be required by local regulations.
Biodegradable oil is stable only for a limited period of time. It
must be used within a period of 2 years of the date of
manufacturing (printed on the recipient).

5.5 Refueling

FOLLOW THE SAFETY PRECAUTIONS!
Be careful and cautious when handling fuels.
The engine must be switched off.
Thoroughly clean the area around the lids to prevent debris
from penetrating into the fuel or oil tanks.
Unthread the lid and fill the tank with fuel (mixture
gasoline/oil) or saw chain oil as may be the case. Fill up to
the lower edge of the tank inlet. Be careful not to spill fuel or
saw chain oil!
Thread the fuel lid as far as it will go.
Clean the threads of the lid and of the tank after
refueling.
Adjusting the lubrication of the saw chain
The engine must be switched off.
You can adjust the feeding speed of the oil pump by means
of the adjusting screw (I) located below at the machine
base. The quantity of oil can be adjusted using a flat screw
driver.

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 / OLMO 22-400B)
- 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

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.
Cold start
1. Prime the bulb (22) if necessary. (If there is gasoline,
prime it once or, at the most, twice in cold conditions.)
See instructions above in general items.
2. Completely close the carburetor's air admission pulling
the "CHOKE" (21) throttle lever until it locks in position
"CHOKE" (21).
3. Activate the machine's start button (15).
4. Check that the mechanical brake (4) is deactivated. To
do so, check that the white-colored plastic piece in the
base is thrust in. If not so, pull the brake handle towards
yourself such that the brake (4) is deactivated.
5. Grasp the machine firmly and avoid any obstacles
being present around the machine. Comply with the
safety measure before starting.
6. Pull the starter handle (14) vigorously. Under normal
conditions, after some few attempts you will hear the
characteristic sound of the first explosions. Stop when
hearing the sound.
