ENGINE OIL RECOMMENDATIONS
The unit has been filled with “break in” engine oil
at the factory. Use a high-quality detergent oil classified
“For Service CC, SD, SE or SF.” Detergent oils keep the
engine cleaner and reduce carbon deposits. Use oil hav-
ing the following SAE viscosity rating, based on the
ambient temperature range anticipated before the next
oil change:
Engine Lubrication System:
Crankcase Oil Capacity..............................................6.8 L (7 U.S. qts.)
COOLANT
Use a mixture of half low silicate, ethylene glycol base
antifreeze and half soft water. Use only soft water and
only low silicate antifreeze. If desired, you may add a
high quality rust inhibitor to the recommended coolant
mixture. When adding coolant, always add the recom-
mended 50-50 mixture.
Cooling System:
CCoolant Capacity
System..............................................................23.7 L (6.3 U.S. gals.)
Engine ..............................................................12.3 L (3.3 U.S. gals.)
Do not remove the radiator pressure cap while
the engine is hot or serious burns from boiling
liquid or steam could result.
Ethylene glycol base antifreeze is poisonous. Do
not use your mouth to siphon coolant from the
radiator, recovery bottle or any container. Wash
your hands thoroughly after handling. Never
store used antifreeze in an open container
because animals are attracted to the smell and
taste of antifreeze even though it is poisonous
to them.
Do not use any chromate base rust inhibitor with
ethylene glycol base antifreeze, or chromium
hydroxide (“green slime”) will form and cause
overheating. Engines that have been operated
with a chromate base rust inhibitor must be
chemically cleaned before adding ethylene glycol
base antifreeze. Using any high silicate antifreeze
boosters or additives also will cause overheating.
We also recommend that you DO NOT use any
soluble oil inhibitor for this equipment.
