FUEL MIXTURE
A
Mix oil with unleaded gasoline (regular grade gasoline
is an acceptable substitute). Us» a clean, high quality
2-cycle oil. Disregard instructions on oil containers. Do
not mix directly in engine fuel tank, as this will allow
oil to enter carburetor which may cause engine to
CAUTION
Page 6
be inoperative. Do not use multi-viscosity oils. Such
oils may not provide adequate lubrication and due to
additives may cause excessive plug fouling. Us(! fresh
gasoline which is blended for the season in which the
engine is used. Measure oil carefully. Excess ve oil
in fuel may cause hard starting or no start, al so ex
cessive smoke and plug fouling.
Experience indicates that alcohol blended fuels i called
gasohol or using ethanol or methanol) can attract
moisture which leads to separation and forma ion of
acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid ongine
problems, the fuel system should be emptied aefore
storage for 30 days or longer. Drain the fuel tani;, start
the engine and let it run until the fuel lines and car
buretor are empty. Use fresh fuel next season. See
Storage section of this manual for additional infor
mation.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
To assure thorough mixing of oil and gasoline—f II con
tainer with gasoline to one quarter full, add oil per chart,
shake container vigorously and then fill remainder of
container with gas. ONCE MIXED, OIL AND
GASOLINE WILL NOT SEPARATE. Use a deal con
tainer and follow the chart below.
WARNING
AC
Never fill fuel tank indoors, when engine
is running or while engine is still hot.
Do not smoke when filling fuel tank.
2. Make certain the auger control handle is in the
t
disengaged (released) position.
3. Insert ignition key into slot. See figure 4. Be cer
tain it snaps into place. Do not turn key.
4. Move choke lever to ON position (cold engine
