c. After the system pressure in the oil separation tank is completely released, slowly
open the screw-plug at the oil filling port, and then rotate the compressor for about
10 turns in the rotation direction of compressor by hand.
d. Utilize a specialized belt-type wrench to remove the lubricating oil filter. Please
note to catch the lubricating oil flowing out into a container. After no more
lubricating oil flows out, clean the lubricating oil filter base.
e. Replace the lubricating oil filter.
f. Remove the oil drain plug and open the ball valve in the oil drain pipe to drain out
the lubricating oil from the oil separation tank. Catch the discharged lubricating oil
with a container and properly dispose of it to prevent any environmental pollution.
g. Close the oil drain ball valve and install the oil drain plug. Fill the oil separation
tank with lubricating oil until the oil level reaches the upper limit. Tighten the
screw-plug at oil filling port.
h. Restart the compressor and allow it to operate in loading state for 5 minutes, and
then check the oil level. If the oil level is low, then the unit should be shut down.
After the system pressure in the oil separation tank is released thoroughly and the oil
level is stabilized, slowly open the screw-plug at the oil filling port and continue to
fill the oil separation tank with sufficient lubricating oil.
4.2 V-Belts
a. After the new V-belts operate for 100 hours, it is necessary to check the tightness or
tension of the belts. If the V-belts are too loose, then adjustment will be required.
Adjustment will be required later every time it operates another 500 - 1,000 hours.
b. It is essential to use replacement V-belts with the correct specifications. V-belts
with the same lot number should be used to ensure consistent tension in each belt.
In addition, it is essential to replace all V-belts simultaneously. Do not use a
mixture of new and used V-belts.
c. To adjust the V-belt tension, the four fixing bolts under the main motor should be
slightly loosened at first, and the adjustment screw can be turned to drive the main
motor to tension the belt until the tension meets the requirement. Then the fixing
bolts of motor should be tightened. Refer to Fig. 4-1.
