4.2.3 Coolant in Cooling System

River water contains large amount of calcium and other impurities, so if it is used, scale will stick to the
engine and radiator, and this will cause defective heat exchange and overheating.

When using antifreeze, always observe the precautions given in the Operation and Maintenance Manual.

Antifreeze is flammable, so be extremely careful not to expose it to flame or fire.

The proportion of anti-freeze to water differs according to the ambient temperature.
For details of the mixing proportions.

If engine is overheated, before adding coolant, wait for the engine to cool down.

If the coolant level is low, it will cause overheating and will also cause problems with corrosion from the
air in the coolant.
4.2.4 Grease

Grease is used to prevent twisting and noise at the joints.

If any part becomes stiff after being used for long time, add grease.

Always wipe off all of the old grease that is pushed out when greasing. Be particularly careful to wipe
off the old grease in places where sand or dirt sticking in the grease would cause wear of the rotating
parts.
4.2.5 Oil and Fuel Storage

Keep indoors preventing any water, dirt, or other impurities from getting in. if drums have to be stored
outside, cover them with a waterproof sheet or take other measures to protect them.

When keeping drum cans for a long period, put the drum on its side so that the filler port of the drums is
at the side to prevent moisture from being sucked in.

To prevent any change in quality during long-term storage. Be sure to use in the order of first in- first
out (use the oldest oil or fuel first).
4.2.6 Filter Elements

Filters are extremely important safety parts. They prevent impurities in the fuel and air circuits from
entering important equipment and causing problems.

Replace all filters periodically. Details see P131-P132.

Do not clean the filters (cartridge type) and use again.

When replacing filter elements, check if any metal particles are affixed to the old filter. If any metal
particles are found, contact your SUNWARD distributor.

Do not open packs of spare filters until just before they are to be used. Always use SUNWARD genuine
filter elements.
