Lube oil capacity may differ from the above volume depending on an engine installed on a machine unit.
(b) Replenishing oil pan with lube oil
If the remaining engine oil level is low, fill the oil pan with the specified engine oil to the specified level
through the filler port.
[NOTICE]
The oil should not be overfilled to exceed the upper limit line. Otherwise a naturally-aspirated
engine may intake lube oil in the combustion chamber during the operation, then white smoke, oil
hummer or urgent rotation may occur, because the blowby gas is reduced in the suction air flow.
In case of turbo-charged engine oil may jet out from the breather or the engine may become faulty.
(4) Coolant water Inspection
Daily inspection of coolant water should be done only by Coolant recovery tank.
(a) Checking coolant water volume
Check the coolant water level in the Coolant recovery tank. If the water level is close to the LOW mark,
open the Coolant recovery tank cap and replenish the Coolant recovery tank with clean soft water to the
FULL mark.
Standard
The water level of the Coolant recovery tank shall be between the upper and lower limit lines.
(b) Replenishing engine with water
If the Coolant recovery tank water level is lower than the LOW mark, open the radiator cap and check
the coolant water level in the radiator. Replenish the radiator with the coolant water, if the level is low.
Check the coolant water level while the engine is
cool.
Checking when the engine is hot is dangerous.
And the water volume is expanded due to the
heat.
Daily coolant water level check and replenishing
shall be done only at the Coolant recovery tank.
Usually do not open the radiator cap to check or
replenish.

Never open the radiator filler cap while the engine and radiator are
still hot. Steam and hot water will spurt out and seriously burn
you. Wait until the radiator is cooled down after the engine has
stopped, wrap the filler cap with a rag piece and turn the cap
slowly to gently release the pressure inside the radiator.
Securely tighten the filler cap after checking the radiator. Steam
can spurt out during operation, if the cap is tightened loosely.
