build up inside the fuel tank depending
on the fuel used, the weather conditions
and the tank venting system.
In order to reduce the risk of burns and
other personal injury from escaping gas
vapor and fumes, remove the fuel filler
cap on your chain saw carefully so as to
allow any pressure build-up in the tank
to release slowly.
Flip up the lever and slowly turn left (1)
to the vent position of the cap at about
1/8 turn where the cap is held in place by
the thread. Once the fumes have been
relieved, turn (2) the cap further to the
1/4 turn position where the tool-less cap
can be removed from the tank thread.
Never remove the fuel filler cap by
quickly turning it to the full 1/4 open
position without letting it vent out any
vapor/pressure build-up at the
1/8 position.
Never remove the fuel filler cap while the
engine is running.
Select bare ground for fueling and move
at least 10 feet (3 m) from the fueling
spot before starting the engine. Wipe off
any spilled fuel before starting your
chain saw.
MS 150 TC
WARNING
Check for fuel leakage
while refueling and during
operation. If fuel leakage
is found, do not start or
run the engine until the
leak is fixed and any
spilled fuel has been
wiped away. Take care
not to get fuel on your
clothing. If this happens,
change your clothing
2
immediately.
Different models may be equipped with
1
different fuel caps.
Toolless cap with grip
WARNING
In order to reduce the risk of fuel spillage
and fire from an improperly tightened
fuel cap, correctly position and tighten
the fuel cap in the fuel tank opening.
To do this with this STIHL cap, raise the
grip on the top of the cap until it is upright
at a 90° angle. Insert the cap in the fuel
tank with the positioning mark on the
grip of the cap and the "open" mark on
the fuel tank opening lining up. Using the
grip, press the cap down firmly while
turning it clockwise as far as it will go
(approx. 1/4 turn). The positioning mark
on the cap should now line up with the
"closed" mark on the tank.
Fold the grip flush with
the top of the cap. Grip
the cap and check for
tightness. If the grip does
not lie completely flush
with the cap and the
detent on the grip does
not fit in the correspond-
ing recess in the filler
opening, or if the cap is
loose in the filler opening,
the cap is not properly
seated and tightened and
you must repeat the
above steps.
Misaligned, damaged or broken cap
If the cap does not drop fully into the
N
opening when the positioning marks
line up and/or if the cap does not
tighten properly when twisted, the
base of the cap may be prematurely
rotated (in relation to the top) to the
closed position. Such misalignment
can result from handling, cleaning
or an improper attempt at
tightening.
