Retensioning during cutting work:
: Shut off the engine first –
and then loosen the nut!
: Hold the bar nose up and use
screwdriver to turn tensioning screw
(1) clockwise until chain fits snugly
against the underside of the bar.
: While still holding the bar nose up,
tighten down the nut firmly.
: Go to chapter “Tensioning the Saw
Chain”
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 "During Operation".
: Shut off the engine.
: Wear work gloves!
: Chain must fit snugly against the
underside of the bar – and, with the
chain brake disengaged, it must still
be possible to pull the chain along
the bar by hand.
: If necessary, retension the chain.

This engine is certified to operate on
unleaded gasoline and the STIHL two-
stroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of high-
quality gasoline and quality two-stroke
air cooled engine oil.
Use mid-grade unleaded gasoline with a
minimum octane rating of 89 (R+M/2). If
the octane rating of the mid-grade
gasoline in your area is lower, use
premium unleaded fuel.
Fuel with a lower octane rating may
increase engine temperatures. This, in
turn, increases the risk of piston seizure
and damage to the engine.
The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines, etc.), but magnesium castings and
catalytic converters as well. This could
cause running problems or even
damage the engine. For this reason
STIHL recommends that you use only
nationally recognized high-quality
unleaded gasoline!
