Chain Oil

For automatic and reliable
lubrication of the chain and guide
bar:
Use only a quality,
environmentally compatible
chain and bar lubricant. STIHL
chain lubricant with non-fling
additive or the rapidly
biodegradable STIHL BioPlus is
recommended
.
Biological chain oil must be resistant
to aging (e.g. STIHL BioPlus) since
it will otherwise quickly turn to resin.
This results in hard deposits that are
difficult to remove, especially in the
area of the chain drive and chain. It
may even cause the oil pump to
seize.
The service life of the chain and guide
bar depends on the quality of the
lubricant. It is therefore essential to use
only a specially formulated chain
lubricant!
HT 73
If special chain lubricant is not available,
you may - in an emergency - use an HD
single grade or multigrade engine oil
with a viscosity that suits the prevailing
outside temperature.
Do not use waste oil! Medical
studies have shown that renewed
contact with waste oil can cause
skin cancer. It also harms the
environment.
.
Waste oil does not have the
required lubricating properties and
is unsuitable for chain lubrication.

Filling Chain Oil
Tank
A full chain oil tank is only sufficient
for half the unit's running time with a
full fuel tank. You should therefore
check the oil level regularly during
cutting work. Never allow the oil tank
to run dry!
:
Thoroughly clean the filler cap and
area around it so that no dirt can fall
into the tank.
:
Take off cap and fill up with chain oil.
:
Refit the filler cap.
If the oil level in the tank does not
change, this may be due to a problem in
the oil supply:
Check chain lubrication, clean oilways,
contact your STlHL dealer if necessary.
