Reactive forces, including kickback, can be dan-
gerous. Careless or improper use of any chain saw
may cause serious or fatal injury.
Have your MAKlTAdealer show you how
to
operate
your chain saw. Observe all applicable local safety
regulations, standards and ordinances.

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.
