Fuel

(Fig.

8)

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 contains highly 

fl

 ammable and it is possible to get the 

serious personal injur y when inhaling or spilling on your body. 
Always pay attention when handling fuel. Always have good 
ventilation when handling fuel inside building.

Fuel

○

  Always use branded 89 octane unleaded gasoline.

○

  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.

○

  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. 

Always start by 

fi

 lling half the amount of gasoline, which is to be used.

Then add the whole amount of oil. Mix (shake) the fuel mixture. Add 
the remaining amount of gasoline.
Mix (shake) the fuel-mix thoroughly before 

fi

 lling the fuel tank.

Fueling

WARNING

(Fig.

9)

○

  Always shut o

ff

   the engine and let it cool for a few minutes before 

refueling.

○

  Do not smoke or bring 

fl

 ames or sparks near the fueling site.

○

  Slowly open the fuel tank (13), when 

fi

 lling  up  with  fuel,  so  that 

possible overpressure disappears.

○

  Tighten the fuel tank cap carefully, after fueling.

○

  Always move the unit at least 3 m from the fueling area before 

star ting.

○

  Always wash any spilled fuel from clothing immediately with soap.

○

  Be sure to check any fuel leaking after refueling.

Before  fueling,  clean  the  tank  cap  area  carefully,  to  ensure  that  no 
dir t falls into the tank. Make sure that the fuel is well mixed by shaking 
the container, before fueling.

Chain

oil

(Fig.

9)

Slowly open the oil tank (14), and 

fi

 ll  up  with  chain  oil.  Always  use 

good quality chain oil. When the engine is running, the chain oil is 
automatically discharged.
Fill up the oil tank (14) with chain oil ever y time when refueling.

NOTE

When pouring fuel (13) or chain oil (14) into the tank, place the 
unit with cap side up. (

Starting

the

cold

engine

(Fig.

10 -15)

CAUTION

Before star ting, make sure that the bar/chain does not touch 
any thing. 

1.  Make sure chain brake is engaged. (

Fig.

10

)

2.  Set ignition switch (15) to ON position (

Fig.

11

).

3.  Push priming pump (16) about ten times so that fuel 

fl

 ows 

through priming pump into carburetor. (

Fig.

12

)

4.  Turn the choke lever (17) to choked position (

Fig.

12

). This will 

automatically lock the throttle in star ting position.

5.  Pull recoil star ter briskly, taking care to keep the handle in your 

grasp and not allowing it to snap back. (

Fig.

13

)

6.  When you hear 

fi

 rst ignition, return the choke lever to run 

position. (

Fig.

12

)

7.  Pull recoil star ter briskly again in the aforementioned manner. 

(

Fig.

13

)

NOTE

If engine does not star t, repeat procedures from 4 to 7.

8.  As soon as engine start, pull throttle trigger full once and release 

immediately. (

Fig.

14

)

Then half-throttle is disengaged.

9.  Make sure chain brake is disengaged. (

Fig.

15

)

Allow the engine about 2-3 minutes to warm up before subjecting 
it to any load.

Do not run the engine at high speed without the load to shor ten 
the longevity of the engine.

Starting

the

warm

engine

Use only 1, 2, 7, and 9 of the star ting procedure for a cold engine.
If the engine does not star t, use the same star ting procedure as for 
a cold engine.

Chain

lubrication

test

Check that chain oil is discharged properly. When the saw chain 
star ts to revolve, point the head of the guide bar to a stump, etc., and 
pull the throttle trigger to per form high-speed operation for around 
10 seconds. If chain oil is sprayed over the stump, it is discharged 
properly. (

Fig.

16

)

Chain

brake

operation

(Fig.

17)

Chain brake (18), is designed to activate in an emergency such as kick-
back action. Please check to verify that it works properly before use.
Application of brake is made by moving the front hand guard towards 
the bar. During the chain brake operation, even if the throttle trigger 
is pulled, the engine speed does not increase and the chain does not 
turn. To release the brake, pull up the front hand guard.

How

to

con

fi 

rm:

1) Turn 

o

ff

  the engine.

2)  Holding the chain saw horizontally, release your hand from the front 

handle, hit the tip of the guide bar to a stump or a piece of wood, and 
con

fi

 rm brake operation. Operating level varies by bar size.

In case the brake is not e

ff

 ective, ask our dealer for inspection and 

repairs.  If  the  engine  keeps  rotating  at  high  speed  with  the  brake 
engaged, the clutch will overheat causing trouble.
When the brake engages during operation, immediately release the 
throttle trigger to stop the engine.

WARNING

Do not carr y the machine with the engine running.

Stopping

(Fig.

18)

Decrease engine speed, and push ignition switch (15) to stop position.

WARNING

Do not put the machine where there are 

fl

 ammable  materials 

such as dried grass, since the mu

ffl

  er is still hot after the engine 

has stopped.

NOTE

If the engine does not stop, it can be forced to stop by rotating the 
choke lever to the choked position.

Before restar ting the engine, ask our dealer for repairs. 

WARNING

○

  Do not overreach or cut above shoulder height.

○

  Use extra caution when felling, and do not use the saw in a nose-

high position or above shoulder height.

CHAIN

CATCHER

The chain catcher is located on the power head just below the chain 
to fur ther prevent the possibility of a broken chain striking the chain 
saw user.
