Chain And Guide Bar Lubrication; Chain Oil; Filling Chain Oil; Checking Automatic Chain Lubrication System - Husqvarna 315, 320 Operator's Manual

A loose chain derails more easily and accelerates wear on guide bar,
chain and drive socket.
• Ensure that the automatic oiling system works and that the cutting
equipment is properly maintained.

CHAIN AND GUIDE BAR LUBRICATION

CAUTION!
Inadequate lubrication can lead to cutting equipment failure and serious or fatal
personal injury.

Chain oil

• The chain and bar are lubricated by an automatic oiling system. We recommend using only chain saw oil,
which is formulated for good adhesion and flow characteristics in
it is important to use the viscosity appropriate to the season. Oil thickens in subfreezing temperatures and
can overload the oil pump and cause parts to fail.
• As a manufacturer of chain saws, we have developed an ideal chain oil which, being based on vegetable
oils, is completely biodegradable. We recommend our oil for the sake of your chain and guidebar and for
the sake of the environment.
• Where chain oil is not available, EP 90 gear oil may be used.
• If you need help choosing chain oil, contact your service dealer.
• Never use old motor oil!
Used motor oil contains impurities which may be harmful to oil pump, guide bar
and chain.

Filling chain oil

• All our chain saw models feature automatic chain lubrication.

Checking automatic chain lubrication system

• Start the chain saw and point the guide bar towards a fixed, light-coloured object
at a distance of approximately 20 cm. After running the saw for a minute, a streak
of oil spatter should be clearly visible on the light surface.
• A full reservoir is sufficient for 20 minutes of steady use.
