GENERAL SAFETY PRECAUTIONS
Lubricating cutting equipment
WARNING! Poor lubrication of cutting
!
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
Chain oil
Chain oil must demonstrate good adhesion to the chain
and also maintain its flow characteristics regardless of
whether it is warm summer or cold winter weather.
As a chain saw manufacturer we have developed an
optimal chain oil which has a vegetable oil base. We
recommend the use of our own oil for both maximum
chain life and to minimise environmental damage. If our
own chain oil is not available, standard chain oil is
recommended.
Never use waste oil! Using waste oil can be dangerous
to you and damage the machine and environment.
IMPORTANT! When using vegetable based saw chain
oil, dismantle and clean the groove in the bar and saw
chain before long-term storage. Otherwise there is a
risk of the saw chain oil oxidizing, which will result in the
saw chain becoming stiff and the bar tip sprocket
jamming.
Filling with chain oil
•
All our chain saws have an automatic chain lubrication
system. On some models the oil flow is also
adjustable.
•
The saw chain oil tank and the fuel tank are designed
so that the fuel runs out before the saw chain oil.
However, this safety feature requires that you use the
right sort of chain oil (if the oil is too thin it will run out
before the fuel), and that you adjust the carburetor as
recommended (a weak mixture may mean that the
fuel lasts longer than the oil) and that you also use the
recommended cutting equipment (a bar that is too
long will use more chain oil). The above conditions
also apply to chain saw models with an adjustable oil
pump.
