To lubricate cutting equipment
WARNING: Poor lubrication of cutting
equipment may cause the chain to snap,
which could lead to serious, even fatal
injuries.
WARNING: Do not use waste oil! Waste oil
is dangerous for persons, the product and
for the environment.
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, with its vegetable oil base, is
also biodegradable. 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.
• In areas where oil specifically for lubrication of saw
chains is unavailable, ordinary EP 90 transmission
oil may be used.
The oil pump is preset at the factory to meet most
lubrication requirements. A full oil tank will last about half
as long as a full tank of fuel. You should therefore check
the level of oil in the oil tank regularly to avoid damage
to the saw chain and bar that could occur due to lack of
lubrication.
