4.3.2 Check Coolant Level
Be sure to stop the machine and allow time to cool. Then
loosen the radiator cap one notch. After the coolant water is
sufficiently cooled and the inner pressure is released, take the
cap off.
If this procedure is neglected, the inner pressure can blow off
the cap. Steam jetting out of the radiator could result in
causing scalding. Follow this procedure under all
circumstances.
Do not continue operation at low coolant level. Air bubble is mixed into radiator, and it causes
damage to the radiator.
<Procedure>
Check the coolant level in the reserve tank. If it is lower than
the limit, open the cap and replenish the coolant.
(Level must be kept above LOW mark.)
When there is a little water or no water in the reserve tank,
remove the radiator cap and make sure to check the water
level. Then supply coolant to the radiator and also the tank,
if necessary. (See 5.5.14)
4.3.3 Check compressor oil level
When you refill the separator receiver tank with compressor oil,
stop the engine, and make sure that the pressure gauge
indicates 0MPa and there is no residual pressure in it, and then
gradually loosen the oil filler cap for refilling oil.
Should any residual pressure be left in the separator receiver
tank, hot compressed air and hot compressor oil jetting out could
cause burning or serious injury to persons nearby.
Place the machine on level ground when checking the oil level.
Check the oil level of the compressor. Correct oil level is
between upper and lower limit of the gauge, when the unit
stops.If the gauge shows lower than the middle level,
replenish oil. (See 5.5.5)
