500 working hours of the compressor.
12.1 Checking Transmission Belts
To check for proper transmission belt tension (g) exert a pressure of approximately 22 lb
(10 kg) on the belt; check the belts do not flex by more than 1 cm (0.39 in) with respect to

Rotate the fan (d) anticlockwise until the belt comes out of
the pulley groove.
• Repeat the procedure on the second belt.
•
Change the belts with new ones: make sure the belt
model and length are exact, check that the characteristics
of the new belt are identical to those of the old one.
