N To return the cap to the open 
position for installation, turn the cap 
(with the grip up) until it drops fully 
into the tank opening. Next, twist the 
cap counterclockwise as far as it will 
go (approx. 1/4 turn) – this will twist 
the base of the cap into the correct 
position. Then, twist the cap 
clockwise, closing it normally.
N If your cap still does not tighten 
properly, it may be damaged or 
broken; immediately stop use of the 
unit and take it to your authorized 
STIHL dealer for repair.
Screw Cap
WARNING
The screwdriver end of the STIHL 
combination wrench or other similar tool 
can be used as an aid in tightening 
slotted fuel filler caps.
See also the "Fueling" chapter in your 
Instruction Manual for additional 
information.
Before Starting
Take off the chain guard (scabbard) and 
inspect the saw for proper condition and 
operation. (See the maintenance chart 
near the end of the instruction manual.)
WARNING
Always check your power tool for proper 
condition and operation before starting, 
particularly the throttle trigger, throttle 
trigger lockout, stop switch and cutting 
tool. The throttle trigger must move 
freely and always spring back to the idle 
position. Never attempt to modify the 
controls or safety devices.
WARNING
Never operate your power tool if it is 
damaged, improperly adjusted or 
maintained, or not completely or 
securely assembled.
WARNING
Check that the spark plug boot is 
securely mounted on the spark plug – a 
loose boot may cause arcing that could 
ignite combustible fumes and cause a 
fire.
For proper assembly of the bar and 
chain follow the procedure described in 
the chapter "Mounting the Bar and 
Chain" of your instruction manual. 
STIHL Oilomatic chain, guide bar and 
sprocket must match each other in 
gauge and pitch. Before replacing any 
bar and chain, see the chapter entitled 
"Specifications" in the instruction 
manual and the section "Kickback" and 
the "ANSI B 175.1-2000 chain saw 
chain saw kickback standard" below.
WARNING
Proper tension of the chain is extremely 
important. In order 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 in order to secure 
the bar. 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 adjust the 
chain while the engine is running!
Keep the handles clean and dry at all 
times; it is particularly important to keep 
them free of moisture, pitch, oil, fuel mix, 
grease or resin in order for you to 
maintain a firm grip and properly control 
your power tool.
Starting
WARNING
To reduce the risk of fire and burn 
injuries, start the engine at least 10 feet 
(3 m) from the fueling spot, outdoors 
only.
Start and operate your saw without 
assistance. For specific starting 
instructions, see the appropriate section 
of the instruction manual. Proper starting 
methods reduce the risk of injury.
Unit vibrations can cause 
an improperly tightened 
fuel filler cap to loosen or 
come off and spill quanti-
ties of fuel. In order to 
reduce the risk of fuel 
spillage and fire, tighten 
the fuel filler cap by hand 
as securely as possible.
