A= FU_L,gNG YOUR UNI;T (See "Specifications, page 2, for location of Fuel Cap.)
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 inter-
nal design ofthe 2-cycle enginerequireslubrication
ofmoving parts Lubricationisprovidedwhen you
use the recommended mixtureof gasolineand oil.
• Gasoline must be clean and not over two
months old. After a short period oftime, gasoline
begins tochemicallybreak down and willform com-
pounds that can cause hard starting and damage in
2-cycle engines
o The correct measure of gasolinetoeilisveryim-
portant. Too much oil will foul the spark plug. Toolit-
tle oilwill cause the engine tooverheat and freeze up
• Always mix the fuel thoroughly in a container
since gasoline and oildo not readily combine. Donot
try to mix fuel directly in the fuel tank
USE THE FOLLOWING:
2_
1 GALLON
REGULAR
UNLF_DED _-
-- OR-- _
4. DO NOT USE:
° 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
5. IMPORTANT POINTS TO REMEMBER
a, Use only recommended fuel mixtures.
b Eliminate all sources of sparks or flame in the
areas where fuel is mixed, poured, or stored.
There should be no smoking, open flames or
work that can cause sparks.
3. HOW TO MIX FUEL
a Pour one-half of the gasoline into an approved
marked container. Do not try to mix fuel directly
in the h_el tank.
b Add entire measure of 2-cycle Engine OiL
c. Mix.
d. Add remainder of gasoline.
e Mix thoroughly for one mim,te.
B, PRE-OPERATBON CHECKS

MA NTENAN©E
Ao AIR FILTER CARE
A dirty air filter decreases engine performance and
increases fuel consumption_
Clean the Air Filter:
• Frequently,
o Always clean after 5 tanks of fuel or 5 hours of
operation, whichever is less.
Follow these steps:
1 Remove the air filter (located above the control
panel; see Figure 15)
2 Wash in soap and water
ICAUTION:I Do not clean filter in gasoline or
other flammable solvent to avoid creating a fire
hazard.
& Squeeze filter dry
4 Add a small amount of oil to coat the filter,
NOTE: Avoid soaking the filter with oil
5 Squeeze out excess oil
6 Replace the air filter.
NOTE: Make sure the filter is properly fitted into the
housing, paying particular attention to the corners.
Bo FUEL TANK UPKEEP
Never use gasoline that is more than 2 months old
in a fuel mixture. Gasoline begins to break down after
