Checking Chain Tension

: Disconnect plug from power
supply.
: Wear work gloves to protect your
hands.
: Disengage the chain brake: Pull the
hand guard (1) against the front
handle.
The chain must fit snugly against the
underside of the bar and it must still be
possible to pull the chain along the bar
by hand.
: If necessary, retension the chain.
MSE 220
A new chain has to be retensioned more
often than one that has been in use for
some time.
: Check chain tension frequently –
see chapter "Operating
Instructions".

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.
