Oil filler cap removed
The saw chain and
guide bar must be continuously lubri-
cated
during operation to protect them from
abnormal
wear.
This is assured by the
automatic chain oiling
system.
The speed-controlled
oil
pump
always draws the amount
of oil required out of the tank
and feeds it to the guide bar
groove. The oil pump
feed rate is designed to provide ade-
quate
lubrication
of the bar and chain under normal opera-
ting conditions using a standard
length Ematic guide bar.
If you would like to increase the oil feed
rate, contact your
STIHL Dealer for assistance.
The
capacities of the oil and fuel tanks are balanced
in
such a
way that a certain amount of oil, depending on
pump feed rate, is
always left in the oil tank when the fuel
tank is empty. This avoids the risk
of the saw being used
unintentionally without chain lubrication.
Always fill the oil tank with chain oil when you refuel.
Important: If you find the oil tank is still full although
the
fuel tank is completely empty, the reason may
be
a
fault in
the chain oil supply
system.
In such
a case,
check chain
lubrication and, if necessary,
clean the oilways or contact
your
STIHL Dealer for assistance.

The service life of the saw chain and
guide bar is greatly
dependent on the
quality of the lubricant. Only use the
chain oil approved and recommended by STIHL.
Warning!
Medical studies
have shown that renewed contact with
waste oil can cause skin cancer. Avoid direct
contact
with
waste oil. If waste oil does get on your skin, wash with
soap
and
water.
Do
not use waste
oil for
any
purpose, and
dispose it only
at authorized disposal locations.
If special chain lubricant is
not
available
you may in an
emergency use one of the high-duty, single
grade engine
oils listed below. Choose the oil
according to the prevailing
outside temperature.

Grade
+10°C
to +40 °C (50 °F to
104°F)

Before refilling, carefully clean
the filler cap and the
area
around it to ensure that no dirt falls into the tank.
