4.2.2 Fuel
 The fuel pump is a precision instrument. If
fuel containing water or dirt is used, it can not
work properly.
 Be careful not to let impurities get in when
storing or adding fuel.
 Always use the fuel specified in the Operation
and Maintenance Manual.
 Fuel may congeal depending on the
temperature when it is used (particularly in
low temperature below -15°C（5°F）. It’s
necessary to use the fuel that is suitable from
the temperature.
 To prevent humidity in air to condense in fuel
tank to form water, top up oil tank after the
work is finished everyday.
 Before starting the engine, or when 10
minutes have passed after adding fuel, drain
the sediment and water from the fuel tank.
 If there runs out of fuel, or if the filters have
been replaced, it is necessary to bleed the air
from the circuit.
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 overheating, 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
 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 filters, 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 filters.
