General Safety Precautions
The use of any chain saw may be hazardous. At full
throttle chain speed can reach 45 mph (20 m/s). It is
important that you read; fully understand and observe
the following safety precautions and warnings. Read
the Owner’s Manual and the safety instructions
periodically.
WARNING !
Reactive forces, including kickback, can be dan-
gerous. Careless or improper use of any chain saw
may cause serious or fatal injury.
Have your MAKITA dealer show you how to operate
your chain saw. Observe all applicable local safety
regulations, standards and ordinances.

WARNING!
Minors should never be allowed to use a chain
saw.
Bystanders, especially children and animals should
not be allowed in the area where a chain saw is in
use (fig. 1).
Never let the saw run unattended.
Store it in a locked place away from children. Fill
the fuel tank to 7/8 th full (see storing the saw).
Do not lend your chain saw without this Owner’s
and Safety Manual. Be sure that anyone using
your saw understands the information given.
Proper use of a chain saw involves
1. the operator

WARNING !
Prolonged use of chain saws exposing the operator
to vibrations may produce Whitefinger disease
(Raynaud’s phenomenon). This phenomenon
reduces the hand’s ability to feel and regulate
temperature, produces numbness and burning
sensations and may cause nerve and circulation
damage and tissue necrosis.
All MAKITA saws are therefore provided with an
antivibration system which is essential for those
using chain saws on a regular or sustained basis.
Antivibration systems do not guarantee that you will
not sustain Whitefinger disesase, however, they
reduce this danger considerably. Nevertheless,
continual and regular users should observe their
hands and fingers and in case of any abnormal
symptoms, seek medical advice immediately.

from energies measured on a test bench.It is not the
angle of the guide bar moved upward in case of a
