Fueling Instructions 
Fuel your chainsaw 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 fueltank of a two cycle 
engine depending on the fuel used, the 
weather conditions, 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 fuel filler cap on the STIHL 
product carefully so as to allow any 
pressure build-up in the tank to release 
slowly. Never remove fuel filler cap while 
the 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.
!Warning!
Check for fuel leakage while refueling 
and during operation. 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. Take care not to 
get fuel on your clothing. If this happens, 
change your clothing immediately.
!Warning!
Unit vibrations can cause an improperly 
tightened fuel cap to loosen or come off 
and spill quantities of fuel. In order to 
reduce risk of fuel spillage and fire, 
tighten the fuel cap by hand with as 
much force as possible.
The screwdriver end of 
the STIHL combination 
wrench or other similar 
tool can be used as an aid 
in tightening slotted fuel 
caps.
Starting
The chain brake must be engaged when 
starting the saw.
!Warning!
Your chainsaw is a one-person saw. 
Do not allow other persons to be near 
the running chainsaw. Start and operate 
your saw without assistance. For 
specific starting instructions, see the 
appropriate section of the owner's 
manual. Proper starting methods reduce 
the risk of injury. Do not drop start. 
This method is very dangerous because 
you may lose control of the saw. Place 
the chainsaw on firm ground or other 
solid surface in a clear area. Maintain 
good balance and secure footing.
!Warning!
Be sure that the guide bar and chain are 
clear of you and all other obstructions 
and objects, including the ground. When 
the engine is started, the engine speed 
with the starting throttle lock engaged 
will be fast enough for the clutch to 
engage the sprocket and turn the chain, 
if the chainbrake is not engaged. If the 
running chain near the upper quadrant 
of the bar nose touches any object, it 
may cause kickback to occur (see 
section on reactive forces).
