How to con

fi

 rm the activation of the chain brake (Fig. 14)

1) Turn 

o

  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.

Fig. 14

In case the brake is not e

 ective, ask Hitachi Authorized Service 

Centers for inspection and repairs.

Starting the cold engine (Fig. 2, 13, 15-18)
CAUTION

 

Before starting, make sure that the guide bar/chain does not 

touch anything.

1.  Push the front hand guard (2) so that the brake is engaged. 

(

Fig. 13

)

2.  Set stop switch (18) to ON position. (

3.  Push priming pump (20) approximately ten times so that fuel 

fl

 ows into carburetor. (

4.  Turn the choke lever (19) to set it in the START position. ( ) 

(

Fig. 16

) This will automatically lock to half-throttle.

5.  Pull recoil starter (21) rapidly, taking care to keep the handle in 

your grasp and not allowing the handle to snap back. (

Fig. 17

)

6.  When you hear 

fi

 rst ignition, return the choke lever (19) to set it in 

the RUN position ( ). (

Fig. 16

)

NOTE

 

When the choke lever is put back to the RUN position ( ) from 

the START position ( ) by hand, the throttle lever will be kept 

half-open (half-throttle).

7.  Pull recoil starter (21) rapidly again in the aforementioned 

manner. (

Fig. 17

)

NOTE

 

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

8.  As soon as the engine starts, pull throttle lever (23) full once with 

the throttle lever lockout (22) pressed and immediately release 

the throttle lever (23). Then half-throttle is disengaged. (

9.  Pull the front hand guard (2) so that the brake is disengaged. 

(

Fig. 2

)

 

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 avoid 

shortening the life of the engine.

Starting the warm engine

Use only 1, 2, 7, and 9 of the starting procedure for a cold engine.

If the engine does not start, use the same starting procedure as for 

a cold engine.

Chain lubrication test (Fig. 19)

Check that chain oil is discharged properly. When the saw chain 

starts to revolve, point the head of the guide bar to a stump, etc., 

and pull the throttle lever to perform high-speed operation for around 

10 seconds. If chain oil is sprayed over the stump, it is discharged 

properly.
