10. Follow
instructions
tensioning and changing accessories.
Improperly tensioned or lubricated chain may either
break or increase the chance for kickback.
11. Keep handles dry, clean, and free from oil and
grease.
Greasy, oily handles are slippery causing loss of
control.
12. Cut wood only. Do not use chain saw for
purposes not intended. For example: do not use
chain saw for cutting plastic, masonry or non-
wood building materials.
Use of the chain saw for operations diff erent than
intended could result in a hazardous situation.
Causes and operator prevention of kickback:
Kickback may occur when the nose or tip of the guide bar
(kickback zone (1) (Fig. 1)) 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 sudden reverse
reaction, kicking the guide bar up and back towards the
operator.
Pinching the saw chain along the top of the guide bar may
push the guide bar rapidly back towards the operator.
Either of these reactions may cause you to lose control of
the saw which could result in serious personal injury. Do
not rely exclusively upon the safety devices built into your
saw. As a chain saw user, you should take several steps to
keep your cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below:
1. Maintain a fi rm grip, with thumbs and fi ngers
encircling the chain saw handles, with both
hands on the saw and position your body and
arm to allow you to resist kickback forces.
Kickback forces can be controlled by the operator,
if proper precautions are taken. Do not let go of the
chain saw.
2. Do not overreach and do not cut above shoulder
height.
This helps prevent unintended tip contact and
enables better control of the chain saw in unexpected
situations.
3. Only use replacement bars and chains specifi ed
by the manufacturer.
Incorrect replacement bars and chains may cause
chain breakage and/or kickback.
4. Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.

Chain brake operation:
If a chain saw hits a solid object at a high speed it reacts
violently and kick back. This is diffi cult to control and
could be dangerous, especially with lightweight tools
that tend to be used in all kind of positions. The chain
brake immediately stops the chain from rotating if there
is an unexpected kickback. The chain brake can be
activated by pressing your hand against the handguard or
automatically by the kick-back itself.
The chain brake can only be reset after the motor has
stopped completely.
Reset the handle to the rear position. (Fig. 2)
Check the function of the chain brake every day.
ADDITIONAL SAFETY WARNINGS
1. Use the electrical voltage listed on the name plate for
the power source.
The use of a voltage that exceeds this may result in
injury.
2. Work without pressure. In addition, always keep your
body warm.
3. Before commencing work, refl ect fully on the work
procedures involved and work to avoid accidents,
otherwise injury may occur.
4. Do not use in the event of bad weather, such as
strong wind, rain, snow, fog, or in areas prone to
rockfall or avalanches.
In bad weather, judgment may be impaired and the
vibration may result in disaster.
5. When visibility is poor, such as during bad weather or
night, do not use the unit. In addition, do not use it in
rain or in a location exposed to rain.
Unstable foothold or loss of balance may result in an
accident.
6. Check the guide bar and saw chain before starting the
unit.
○ If the guide bar or saw chain is cracked, or the product
is scratched or bent, do not use the unit.
○ Check if the guide bar and saw chain are securely
installed. If the guide bar or saw chain is broken or
dislodged, this may result in an accident.
7. Before starting work, check to ensure the switch does
not engage unless the lock-off button is pressed.
If the unit does not working properly, immediately stop
using and request repair from your Hitachi Authorized
Service Center.
