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.
 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
reserve tank , if necessary. (See 5.5.17)
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 0psi (0bar) 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)
(Oil level drops when starting operation.)
