MAINTENANCE AND SERVICE
Check V-belt tension
The V-belt could lose tension during transportation. Please check the V-belt tension before starting
the compressor.
Tension V-belt
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-belt too tight. This damages bearings of compressor and motor. The V-belt should
only be tensioned until there is no noise caused by slipping during start.
