Fueling

MIX
Before fueling, clean the filler cap and
the area around it to ensure that no dirt
falls into the tank. Always thoroughly
shake the mixture in the canister before
fueling your machine.
In order to reduce the risk of burns
or other personal injury from
escaping gas vapor and fumes,
remove the fuel filler cap carefully
so as to allow any pressure build-up
in the tank to release slowly.
After fueling, tighten fuel cap as
securely as possible by hand.
Use a suitable tool (e.g. screwdriver
end of combination wrench) to
tighten slotted fuel caps.

Chain Lubricant

For automatic and reliable
lubrication of the chain and guide
bar – use only an environmentally
compatible quality chain and bar
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, 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.
