22. BELT TENSIONING AND REPLACEMENT
During the first usage period of the machine, belts will break in and this will unavoidably reduce tension.
After a few days' usage, re-adjust belt tension, without overtensioning, to avoid overloading and damaging motor
and shaft bearings.
Inspect belts at least once every 2 months to check for wear and restore an optimal tensioning.
Tension is to be checked by applying pressure on belts halfway through their length: a belt sagging of approx. 10
mm should be noticed.
To tension or replace belts, lockout the main switch after setting it to "0", then remove the machine rear guard.
Belt tensioning - upper and lower horizontal shafts
a)
Slacken the nut in the tie-rod fixed to the motor flange.
b)
Axially adjust the motor by acting on the tie-rod until belts are tensioned as indicated above
c)
Re-tighten the tie-rod nut.
Belt tensioning - left- and right-hand vertical shafts
a)
Slacken the 4 motor flange fastening screws.
b)
Tension the belt by prying on the motor flange using the wrench supplied (1) (Fig. 18)
c)
Tighten the motor flange screws
When replacing the belt, make sure the arrow printed on the external side indicates the shaft direction of rotation.
23. MACHINE STARTING AND STOPPING
- Make sure the emergency mushroom buttons are not pressed; if they are, give the mushroom button ¼ turn to the
left;
- Make sure that air system pressure is correct
- Make sure the upper guard is properly closed;
- Make sure the suction plant is on;
- Set the main switch to "1";
