4. DO NOT USE:
1. FUEL MIXTURE
o Your unit is powered by a 2-cycle engine which
requires a fuel mixture of regular, unleaded
gasoline and a high quality engine oil specially
made for 2-cycle, air-cooled engines, The internal design of the 2-cycle engine requireslubrication
of moving parts Lubrication is provided when you
use the recommended mixtureof gasolineand oil.
• Gasoline must be clean and not over two
months old. After a short period of time, gasoline
begins to chemically break down and willform compounds that can cause hard starting and damage in
2-cycle engines
o The correct measure of gasolinetoeilisveryimportant. Too much oil will foul the spark plug. Toolittle oil will cause the engine tooverheat and freeze up
• Always mix the fuel thoroughly in a container
since gasoline and oil do not readily combine. Do not
try to mix fuel directly in the fuel tank
2_
page 2, for location of Fuel Cap.)
USE THE FOLLOWING:
° BIA OIL (Boating Institute of America) --- Does not have proper additives for air-cooled,
2_cycle engines and could cause damage
o AUTOMOTIVE OIL ---Does not have proper additives for 2-cycle
engines and could cause damage
• GASOLINE CONTAINING ALCOHOL
(High Test, Premium or Gasohol) ---Stiffens
critical carburetor fuel metering
eler_ents and causes engine damage from
overheating
--Increases vapor lock (causes hard starting)
-- Attracts water causing corrosion damage

Never use gasoline that is more than 2 months old
in a fuel mixture. Gasoline begins to break down after
a short period of time and will form compounds that
cause hard starting and damage in 2-cycle engines
Figure 15
1 Inspect the unit for fuel leaks each time it is
used. Repair or replace parts as necessary
2 Always begin operation with a clean, fresh
mixture of fuel.
3 Drain all fuel from the unit or allow unit to run
out of fuel before storing for 30 or more days.
