3.1.2 Lube oil
(1) Selection of Engine Lube Oil
Use the following lube oil:
API Classification CD
Standards of American Petroleum Institute
SAE Viscosity 15W40
Standards of Society of Automotive Engineering
Using other than the specified lube oil
will lead to seizure of parts inside the engine and gear
device, abnormal wear, and shorten engine life. It will
also affect the starting ability and power output.
(2) Handling the Lube Oil
• When handling and storing lube oil, be careful not
to allow dust and water to enter the lube oil. Clean
around the filler port before refilling.
• Do not mix lube oils of different types or brands.
Mixing may reduce the lubricating performance
3.1.3 Fresh Cooling Water
• Always use soft water (tap water) for the fresh water.
Never use dirty water or hard water. Impurities in
the cooling water cause scale and rust to build up in
the cooling system reducing cooling efficiency and
causing the engine to overheat.
• During the cold season, add antifreeze to the cooling
water to prevent freezing.
• Failure to add antifreeze will result in damage to
various parts in the cooling water system.
• Consult your Yanmar dealer or distributor on the use
of antifreeze and detergents.
• Refer to the instructions accompanying the
antifreeze for the proper mixing ratio.
Select the ratio for the lowest temperature of the
cold season. If the mixture is toothick, the cooling
efficiency will be reduced.
• Do not mix different brands of antifreeze. Mixing
reduces cooling efficiency and leads to parts
damage.
• When the amount of cooling water is too low, refill
with fresh water only.
