STIHL Oilomatic chain, guide
bar and sprocket must
match each other
in gauge and pitch.
Before replacing
any
bar and chain,
see
the sections
on
"Specifications",
kickback and the ANSI B 175.1-1985
chain saw kickback standard
in this manual.
Warning!
Proper tension of the
chain is extremely important.
In or-
der
to
avoid improper
setting, the tensioning procedure
must
be followed
as
described in
your manual. Always
make sure the hexagonal nut(s) for the sprocket
cover is
(are) tightened securely after tensioning the
chain. Never
start the saw with the sprocket cover loose. Check
chain
tension once more
after having tightened
the nut(s) and
thereafter
at
regular intervals (whenever the
saw
is shut
off). If the chain becomes loose while cutting, shut off the
engine and then tighten.
Never try to tighten the chain
while the engine
is running!
Fueling
Your STIHL chain
saw uses an oil-gasoline mixture for fuel
(see chapter "Fuel" of your owner's
manual).
Warning!
Gasoline is an extremely
flammable fuel. Use extreme
caution
when handling gasoline or fuel mix. Do not smoke
or bring any fire or flame near
the fuel
(ill. 5).
Fueling Instructions
Fuel your chain saw in well-ventilated areas, outdoors
only.
Always
shut off the engine and allow it to cool before
refueling. Gasoline
vapor pressure may build up
inside the
gas tank
of
a two
cycle
engine depending
on
the fuel
used, the weather
condition, and the venting system
of the
tank. In order to
reduce the risk of burns or other personal
injury from
escaping
gas vapor
and fumes,
remove the gas
cap
on
the STIHL product carefully
so as to
allow any
pressure
build-up in the tank to release slowly. Never re-
move fuel filler cap while engine is running.
Select bare ground for fueling and
move
at least 10 feet
(3 m) from fueling spot before starting the engine. Wipe off
any spilled fuel before
starting
your saw,
and check for
leakage.
Check for fuel leakage while refueling and during opera-
tion. If fuel or oil leakage is found, do not start
or run
the
engine until leak is fixed and spilled fuel
has been wiped
away. Tighten the fuel cap after filling to avoid
spillage and
risk of fire.
Starting
Warning!
Your chain saw is a one-person saw. Do not allow other
persons to be near the running chain saw. Start and oper-
ate your saw
without
assistance. For specific starting in-
structions,
see
the appropriate section of the owner's
manual. Proper starting methods
reduce the risk of injury. 7
