General Safety Precautions - Makita DCS34 Manuel D'emploi Et De Sécurité

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 peri-
odically.
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
manual. Be sure that anyone using your saw un-
derstands the information given.
Proper use of a chain saw involves

2. the saw
3. the use of the saw.

* The Computed Kickback Angle is a calculated value
from energies measured on a test bench. It is not the
angle of the guide bar moved upward in case of a
KICKBACK.
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
Z62.-03
using chain saws on a regular or sustained basis.
Z62.3-04
Antivibration systems do not guarantee that you
will not sustain Whitefinger disesase, however, they
reduce this danger considerably. Nevertheless,
B75.-2000
continual and regular users should observe their
SAE J335
hands and fingers and in case of any abnormal
symptoms, seek medical advice immediately.
Maximum Computed Kickback Angle
(CKA)* without using the chain brake when
using the recommended bar and chain
combinations
(In this example the CKA is
2°).
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!
Reduced Kickback Bar and
Chain combination that has been
evaluated with the power head
to achieve kickback protection
(according to ANSI and CSA
standards).
