Check V-belt tension
The compressors LW 170 E Nautic and LW 170 D Nautic are
driven by V-belts. Check correct V-belt tension regularly, adjust if
necessary. The V-belt could lose tension during transportation.
Please check the V-belt tension before starting the compressor.
Tension V-belts
• Switch off the compressor unit, pull the plug if necessary.
• Tilt the compressor slightly aside.
• Loosen mounting screws of the motor flange (Fig. 1+2).
• Turn clamp nut until correct V-belt tension (Fig. 3).
Rotation direction clockwise: increase V-belt tension.
Rotation direction anti-clockwise: reduce V-belt tension.
• Tighten mounting screws of the motor flange.
• Check V-belt tension and adjust if necessary.
Correct V-belt tension
Do not tension V-belts too tight. This damages bearings of com-
pressor and motor. The V-belts should only be tensioned until
there is no noise caused by slipping during start.
We recommend using a V-belt tension gauge.
