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 lean 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).
Checking chain lubrication

The position of the chain tensioning screw on our chain saws
varies from model to model. See instructions under the

If our own chain oil is not available, standard chain oil is
recommended.
Never use waste oil! This is dangerous for yourself, the
machine and the 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.
