BELT DRIVE
If the air-end shaft and its engine are belt-driven, make sure that the pulleys assembled on shafts
are lined up and belts are properly tightened.
For a belt drive, you are recommended to use the model “POLY V” with a tension and not
exceeding
1500N
.
As to the pulley fitted to the air-end shaft, diameter should not be smaller than
2.76inches
.
WARNING!
An excessive belt tension causes a
shorter life of the air-end bearings.
Once the machine is started, the
transmission must be protected to
avoid staff accidents.

DIRECT DRIVE WITH COUPLING
If the transmission between air-end and motor shaft is direct driven, the two shafts must be
connected with each other with a flexible coupling (
picture 7
).
WARNING!
The flexible coupling must not be lubricated.
Make sure that motor shaft and air-end shaft
are correctly lined up.
Once the machine is started, the flexible
coupling must be protected so as to avoid
staff accidents.
