Check oil level
Warning
!
Check oil level daily. Never start the compressor with a too low oil level. Risk of accidental
loss, destruction or deterioration.
Check the oil level before each operation of the unit by using
the oil dipstick.
Oil level check as follows:
• Unscrew oil dipstick
• Wipe off oil residues
• Insert the oil dipstick back into its tube and screw it until
stop
• Unscrew oil dipstick again
The oil level should be between the notch and the end of the
oil dipstick. If there is no oil between the notch and the end
of the oil dipstick, refill immediately new full synthetic
compressor oil.
Check V-belt tension
The V-belts could lose tension during transportation. Please check the V-belt tension before starting
the compressor.
Tension V-belts
To tighten V-belt tension, loosen 4 mounting nuts of the drive motor. Use the tensioning screw to
move the electric motor until the V-belt tension is sufficient. Then, tighten mounting nuts and check
V-belt tension.
We recommend using a V-belt tension gauge.
Correct V-belt tension
Do not tension V-belts too tight. This damages bearings of compressor and motor. The V-belts
should only be tensioned until there is no noise caused by slipping during start.
