Note 1: Change oil and filter after first eight (8) hours of
operation and then every 100 hours thereafter. Change sooner
when operating under a heavy load or in a dusty or dirty
environment or in high ambient temperatures.
Note 2: Service more often when operating in dirty or dusty
conditions.
Note 3: Check valve clearance and adjust (if necessary) after
first 50 hours of operation and every 100 hours thereafter.
FUEL AND OIL RECOMMENDATIONS
GASOLINE:
We recommend the use of clean, fresh lead-free gasoline. A minimum
of 85 octane is recommended. The use of lead-free gasoline results
in fewer combustion deposits and longer valve life.
Note: Using a fuel additive such as STA-BIL® fuel stabilizer, or an
equivalent, will prevent gum deposits from forming in the engine’s
fuel system.
Note: Some fuels, called oxygenated or reformulated gasolines,
are gasolines blended with alcohols, ethers or ethanol. Excessive
amounts of these blends can damage the fuel system or cause
performance problems. Do not use gasoline which contains Metha-
nol. Use gasoline with the lowest percentage of alcohol, ether or
ethanol—10% or less.
It is also recommended that gasoline be purchased in small quanti-
ties, not more than a 30 day supply. FRESH gasoline minimizes gum
deposits, and also will ensure fuel volatility tailored for the season in
which the engine will be operated.
LUBRICATION:
Oil has four purposes. It cools, cleans, seals and lubricates. During
normal operation, small particles of metal from the cylinder walls,
pistons, bearings and combustion deposits will gradually contaminate
the oil. Dust particles from the air also contaminate the oil forming an
abrasive mixture which can cause wear to all of the internal moving
parts of the engine, if the oil is not changed regularly. Fresh oil also
assists in cooling. Old oil gradually becomes thick and loses its cooling
ability as well as its lubricating qualities.
RECOMMENDED OIL TYPE:
Using the proper type and weight of oil in the crankcase is extremely
important. Check the oil before each use and change the oil regularly
(see Figures 1-1 through 1-5). Failure to use the correct oil, or using
dirty oil, can cause premature engine wear and failure.
Use only high quality detergent oil rated with an API service
classification SN or higher. Do NOT use oil designated "for diesel
engines only" (example: CD).
The recommended oil weights include the following:
• During summer months: SAE 30. An acceptable substitute is
SAE 10W-30. After first oil change, synthetic oil is acceptable.
• During winter months: SAE 5W-30 or synthetic 5W-30. DO NOT USE
SAE 10W-40. After first oil change, synthetic oil is acceptable.
CHANGE OIL:
See "Section 14: Specifications" for crankcase oil capacities. Use no
special additives. Make sure that the unit is level when filling with oil.
DO NOT OVERFILL.
IMPORTANT: DO NOT OVERFILL. Check and maintain oil level regu-
larly. Change oil and filter after first eight (8) hours of operation.
Thereafter, change oil and filter every 100 hours of operation. Change
oil more often if engine is operated in dirty or dusty conditions or if
engine is operated under heavy loads or in high ambient air tempera-
tures.
