General Safety Precautions; The Operator - Makita EA7300P Operator's And Safety Manual

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 dangerous.
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 Operator's
and Safety Manual. Be sure that anyone using your
saw understands the information given.

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 an-
tivibration system which is essential for those using
chain saws on a regular or sustained basis. Antivi-
Z62.-03
bration systems do not guarantee that you will not
Z62.3-04
sustain Whitefinger disesase, however, they reduce
this danger considerably. Nevertheless, continual and
B75.-2000
regular users should observe their hands and fingers
SAE J335
and in case of any abnormal symptoms, seek medical
advice immediately.

(CKA)* without using the chain brake when
using the recommended bar and chain
combinations (In this example the CKA is 45°).

(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 seri-
ous injury!
Always use two hands when op-
erating the chain saw!
