8. Install the saw chain properly, in accordance with the
instruction manual.
If installed incorrectly, the saw chain will come off the
guide bar and injury may occur.
9. Never remove any of the safety devices equipped
on the chain saw (brake lever, lock-off button, chain
catcher etc.).
In addition, do not alter or immobilize them.
Injury may occur.
10. In the following cases, switch the unit off and ensure
the saw chain is no longer moving:
○ When not in use or being repaired.
○ When shifting to a new work location.
○ When inspecting, adjusting or replacing the saw
chain, guide bar, chain case and any other part.
○ When refi lling the chain oil.
○ When removing dust etc. from the body.
○ When removing obstacles, trash or sawdust
generated from work from the work area.
○ When you take off the unit, or when you get away from
the unit.
○ Otherwise, if you sense danger or anticipate risk.
If the saw chain is still moving, an accident may occur.
11. Work should generally be performed individually.
When multiple individuals are involved, ensure
suffi cient spacing between them.
In particular, when felling standing trees or working on
a slope, if you anticipate trees falling, rolling or sliding,
ensure there is no danger to other workers.
12. Remain more than 50 ft (15 m) away from other
people.
In addition, when working with multiple persons,
remain 50 ft (15 m) or more apart.
○ There is a risk of impact with scatters and other
accidents.
○ Prepare a whistle alert etc. and determine appropriate
contact method for other workers beforehand.
13. Before felling standing trees, ensure the following:
○ Determine a safe evacuation location prior to felling.
○ Remove obstacles (e.g., branches, shrubs) in
advance.
○ Based on a comprehensive evaluation of the state
of the tree to be felled (e.g., trunk bend, tension of
branches) and the surrounding situation (e.g., state of
adjacent trees, presence of obstacles, terrain, wind),
decide on the direction in which the standing tree will
fall and then plan the felling procedure.
Careless felling may result in injury.
14. When felling standing trees, ensure the following:
○ During work, be very careful of the direction in which
trees fall.
○ When working on a slope, ensuring the tree will not
roll, always work from the uphill side of the terrain.
○ When the tree starts falling, switch the unit off , alert
the surroundings, and immediately retreat to a safe
location.
○ During work, if the saw chain or guide bar become
entangled in the tree, switch off and use a wedge.
15. During use, if the unit performance deteriorates,
or you notice any abnormal sound or vibration,
immediately switch off and discontinue use, and
return to your Hitachi Authorized Service Center for
inspection or repair.
If you continue using, injury may occur.
16. If the unit is accidentally dropped or exposed to
impact, inspect carefully for damage or cracks and
ensure there is no deformation.
If the unit is damaged, cracked or deformed, injury
may occur.
17. When transporting the unit by car, secure the unit to
prevent it moving.
There is a risk of accident.
18. Do not switch the unit on while the chain case is
attached.
Injury may occur.
19. Ensure there are no nails and other foreign objects in
the material.
If the saw chain impact on the nail etc., injury may
occur.
20. To avoid the guide bar becoming entangled with the
material when chopping on a verge or when subject
to the weight of material while cutting, install a
supporting platform close to the cutting position.
If the guide bar becomes entangled, injury may occur.
21. If the unit is to be transported or stored after use,
either remove the saw chain, or attach the chain
cover.
If the saw chain comes into contact with your body,
injury may occur.
22. Adequately care for the unit.
○ To ensure work can be performed safely and
effi ciently, care for the saw chain to ensure it provides
optimal cutting performance.
○ When replacing the saw chain or guide bar,
maintaining the body, fi lling oil etc., follow the
instruction manual.
23. Ask the shop to repair the unit.
○ Do not modify this product, since it already complies
with the applicable safety standards.
○ Always refer to your Hitachi Authorized Service
Center for all repairs.
Attempting to repair the unit yourself may result in an
accident or injury.
