Chain Lubricant; Filling Chain Oil Tank - Stihl MS 441 C-M Instruction Manual

Chain Lubricant

For automatic and reliable lubrication of
the chain and guide bar – use only an
environmentally compatible quality
chain and bar lubricant. 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, clutch 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.
Do not use waste oil. Renewed
contact with waste oil can cause
skin cancer. Moreover, waste oil is
environmentally harmful.
Waste oil does not have the
necessary lubricating properties
and is unsuitable for chain
lubrication.

Filling Chain Oil Tank

Preparing the machine
N
Thoroughly clean the oil filler cap
and the area around it to ensure that
no dirt falls into the oil tank.
N Always position the machine so that
the filler cap is facing upwards.
N Open the filler cap.
Filling the chain oil tank
Standard oil pump
N Fill the chain oil tank each time the
fuel tank has been filled
Oil pump with increased delivery rate
(available option)
It is necessary to check and refill the oil
tank frequently – see "Adjusting the oil
quantity".
N Refill the oil tank when the fuel tank
is approximately half empty
All versions
Take care not to spill chain oil while
refilling and do not overfill the tank.
STIHL recommends use of the STIHL
filling system for chain oil (available
option).
N Close the filler cap
There must still be a small amount of oil
in the oil tank when the fuel tank is
empty.
If the oil tank is still partly full, the reason
may be a problem in the oil supply
system: Check chain lubrication, clean
the oil passages, contact a servicing
dealer if necessary. STIHL recommends
that maintenance and repair work be
carried out only by authorized STIHL
dealers.
