CHECK
- The tightness of the screws must be checked at the latest after 50 hours of operation. This
check must then be repeated every 500 hours of operation.
- The tightening torque for the screws is 27 daN.m ± 10 %.
- 1 daN = 1 Kg.
D12 BRAKING
CHECK
- Check the braking system by disconnecting the coil 1 (Fig. D12/1 and D12/2) from the hydraulic
block on the chassis (to access the block, remove the casing on the chassis’ right-hand side)

The lifting platform must not move forward.

- Adjust the tension between the crankcase and alternator pulleys.
- Under thumb pressure (98 N), the tension should be 7 to 9 mm (Rep. A-Fig. D13/2)
