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
Operator's Manual and the safety instructions periodically.
WARNING !
Reactive forces, including kickback, can be
da n 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.
Empty the fuel and oil tank (see storing the saw).
Do not lend your chain saw without this Operator'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

Physical Condition
You must be in good physical condition and mental
health and not under the influence of any substance
(drugs, alcohol), which might impair vision, dexterity
or judgment.
Prolonged use of chain saws exposing the operator
to vibrations may produce Whitefinger disease
(Ray naud'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.
Z62.1-15
Antivibration systems do not guarantee that you
Z62.3-11
will not sustain Whitefinger disesase, however, they
reduce this danger considerably. Nevertheless,
B175.1-2012
continual and regular users should observe their
hands and fingers and in case of any abnormal
symptoms, seek medical advice immediately.
Maximum Computed Kickback Angle
O
(CKA)* without using the chain brake when
using the recommended bar and chain
combinations (In this example the CKA is 45°).
Maximum Computed Kickback Angle
O
(CKA)* with using the chain brake when
using the recommended bar and chain
combinations (In this example the CKA is 40°).
Contact of the guide bar tip with
any object should be avoided!
Tip contact may cause the guide
bar to move suddenly upward
and backward, which may cause
serious injury!
Always use two hands when
operating the chain saw!
