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 ob-
serve 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 DOLMAR dealer show you how to ope-
rate 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

saws:

MaximumComputed Kickback Angle
(CKA)* with using the chain brake when
using the recommended bar and chain
combinations (In this example the CKA is 40°).
WARNING !
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 DOLMAR 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.

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.
Always use two hands when
operating the chain 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.
Reduced Kickback Bar and
Chain combination that has been
evaluated with the power head
to achieve kickback protection
(according to ANSI and CSA
standards).
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!
