4. Operating procedures

Fuel (Fig. 2-1)
WARNING!
The chain saw is equipped with a two-
stroke engine. Always run the engine on
fuel, which is mixed with oil.
Provide good ventilation, when fueling or
handling fuel.
Fuel
Make sure to use gasoline with a minimum
octane number of 89RON (USA/Canada: 87AL
Use genuine two-cycle oil or use a mix
between 25:1 to 50:1, please consult the oil
bottle for the ratio or HITACHI dealer.
Only for the state of California at 50:1.
If genuine oil is not available, use an anti-
oxidant added quality oil expressly labeled for
air-cooled 2-cycle engine use(JASO FC
GRADE OIL or ISO EGC GRADE). Do not use
BIA or TCW (2-stroke water-cooling type)
mixed oil.
Never use multi-grade oil (10 W/30) or waste
oil.
Always mix fuel and oil in a separate clean
container.

CS30EJ/CS35EJ
Always start by filling half the amount of fuel,
which is to be used. Then add the whole
amount of oil. Mix (shake) the fuel mixture. Add
the remaining amount of fuel.
Mix (shake) the fuel-mix thoroughly before filling
the fuel tank.
Fueling
WARNING! (Fig.2-1B)
Always shut off the engine before refuel-
ing.
Fig. 2-4 Slowly open the fuel tank (1), when filling
up with fuel, so that possible over-
pressure disappears.
Tighten the fuel cap carefully, after fuel-
ing.
Always move the unit at least 3 m (10 ft.)
from the fueling area before starting.
Before fueling, clean the tank cap area care-
fully, to ensure that no dirt falls into the tank.
Make sure that the fuel is well mixed by
shaking the container, before fueling.
Chain oil (Fig. 2-1B)
Fill up with chain oil (2). Always use good
quality chain oil. When the engine is running,
the chain oil is automatically discharged.
NOTE!
When pouring fuel (1) or chain oil (2) into the
tank, place the unit with cap side up.
(Fig. 2-1B)
ADJUSTMENT OF CHAIN OIL SUPPLY
The chain oil quantity discharged through the
lubrication system is factory adjusted to the
maximum. Adjust the quantity in accordance
with the operating condition.
Turn the adjusting screw (1) counterclockwise
to decrease the quantity and turn it clockwise to
increase the quantity. (Fig.2-1C)
Do not try to turn the screw beyond level marks.

Starting (Fig. 2-2,3)
WARNING!
When the engine starts with the throttle
lock engaged, the engine speed is high
enough to make the chain rotate.
CAUTION!
Before starting, make sure chain brake is
disengaged (if so equipped) and that the
bar/chain does not touch anything.
1. Set ignition switch (1) to ON position.
* Push priming bulb (5) several times so
that fuel flows through bulb into carburetor.
(If so equipped)(Fig. 2-2,3)
2. With the safety trigger (2) pressed pull
throttle trigger (4) and push throttle lock (3),
then slowly release the throttle trigger first,
then the safety trigger.
This will lock the throttle in starting position.
