attachments have completely stopped before clearing
debris or removing grass from the cutting attachment.
○ Always carry a fi rst-aid kit when operating any power
equipment.
○ The muffl er gets very hot during and after use. This also
applies during idling.
Be aware of the fi re hazard, especially when working
near fl ammable substances and/or vapours.
WARNING
The exhaust fumes from the engine are hot and may
contain sparks which can start a fi re. Never start the
machine indoors or near fl ammable material.

Maintenance safety

○ Maintain the unit/machine according to recommended
procedures.
○ Disconnect the spark

possibility of personal injury with recoil spring.
WARNING
Improper maintenance could result in serious engine
damage or in serious personal injury.
Transport and storage

care and use common sense. Contact Hitachi Authorized
Service Centers if you need assistance.
WARNING
KICKBACK DANGER (Fig. 2)
One of the most severe dangers when working with a chain
saw is the possibility of kickback. Kickback may occur when
the upper tip of the guide bar touches an object, or when
the wood closes in and pinches the saw chain in the cut. Tip
contact in some cases may cause a lightning fast reverse
reaction, kicking the guide bar up and back toward you.
Pinching the saw chain along the top of the guide bar may
also push the guide bar rapidly back towards you. Either of
these reactions may cause you to lose control of the chain
saw which could result in serious personal injury. Even though
your chain saw has safety built into its design, you should not
rely on these safety features exclusively. Know where your
guide bar tip is at all times. Kickback does occur if you allow
the kickback zone (1) of the guide bar to touch an object.
Do not use that area. Kickback from pinching is caused by
a cut closing and pinching the upper side of the guide bar.
Study your cut and make sure it will open as you cut through.
Maintain control when the engine is running by always keeping
a fi rm grip on the chain saw with your right hand on the rear
handle, your left hand on the front handle and your thumbs and
fi ngers encircling the handles. Always hold the chain saw with
plug before performing
both hands during operation and cut at high engine speed.
Follow manufacturer's
instructions for the saw chain. The lack of this maintenance
may increase the possibility of kickback.

ASSEMBLY PROCEDURES

WARNING
Switch off the engine before carrying out any checks or
maintenance.
Never try to start engine without side case, guide bar and
chain securely fastened.
1. Pull the front hand guard (2) toward the front handle to
check that the chain brake is disengaged. (Fig. 3)
2. Remove guide bar clamp nut (3). Remove the side case
(4). (Fig. 4)
* In case of installing the spiked bumper (5), install the
spiked bumper (5) to the unit with two screws. (Fig. 5)
3. Install the guide bar (6) onto the bolts (7), then push it
toward the sprocket (8) as far as it will go. (Fig. 6)
4. Confi rm the direction of saw chain (9) is correct as in the
fi gure, and align the chain on the sprocket (8). (Fig. 6)
5. Guide the chain drive links into the bar groove all around
the guide bar.
6. Install the side case (4) onto the bolts (7).
Make sure that the boss of chain tension adjust bolt (10)
fi ts into the hole (11) of the guide bar. (Fig. 6)
Then tighten the guide bar clamp nut (3) by hand that
allows the guide bar end to move up and down easily.
(Fig. 7)
7. Raise the guide bar end, and tighten the chain (9) by
turning the tension adjustment bolt (12) clockwise until
the chain fi ts snugly against underside of guide bar (6).
The chain is correctly tensioned when there is no slack
on the underside of the guide bar. (Fig. 8, 9)
CAUTION
PROPER TENSION IS EXTREMELY IMPORTANT
8. Raise the guide bar end and securely tighten the guide
bar clamp nut (3) with the combi box spanner (14). (Fig.
10)
9. A new chain will stretch so adjust the chain after a few
cuts and watch chain tension carefully for the fi rst half
hour of cutting.
NOTE
Check the chain tension frequently for optimum
performance and durability.
CAUTION
○ When the chain is excessively tightened, the guide bar
and chain will be damaged rapidly. Conversely, when
the chain is excessively loosened, it may get out of the
groove in the guide bar.
○ Always wear gloves when touching the chain.
WARNING
During operation, hold chain saw fi rmly with both hands.
A single hand operation may cause serious injury.
