For reasons of space, while the other fixing holes are smooth with a 15 mm diameter, a fixing hole of the
fixed flange is threaded (M14): to prevent jeopardising the integrity of the thread, do not fasten this screw
with a torque greater than 120 Nm.
Do not disassemble the support blocks of the screw and do not loosen the locking ring nuts
of the worm screw.
If needed to reassemble the worm screw, after having tightened a ring nut, place a dial
gauge on the screw, on the opposite side to the motor connection. Start to fasten the other
locking ring nut. Rotate the screw and fasten the ring nut until the displacement read on the
lower dial gauge is less than 0,02 mm. If performing this operation for the first time, contact
Battioni Pagani for further information.
WARNING: Bronze crown screws of Revoblock 10 and 14 must be 150 Nm.
Tightening M14 REVOBLOCK 14 Ø 200 - 250 must be 200 Nm.
Tightening M12 REVOBLOCK 7-10 Ø 200 MY 21 must be 142 Nm.

4.3 - PRELIMINARY CHECKS

Before starting the Machine it is necessary to carry out the following operations:
- Verify that the machine has not been damaged during the installation phase;
- Verify that it moves freely and that all movable parts rotate freely;
- Verify that protection devices are fastened;
- Before starting the system it is necessary to verify that all components have been installed correctly and
that oil in the tank is at the intended level.
- Remove air from the hydraulic system allowing it to run 10÷15 minutes without any load in order to avoid
foaming and irregular operation.
- Allow the hydraulic system to run for 30 minutes without any load, connecting it to an external filter with
at least a 10 μm element or with a filtering capacity that is double what is normal for the system.
- Verify any leaks in the hydraulic system, restore oil level.
- Run in the system with 10/15 full runs of the joint, if possible with load reduced of 40-60% to that of
calculation (in case of pipe filled with fluid, it is sufficient to consider the pipe empty). Operations must
not be consecutive to avoid overheating the material (consider one minute rest between one operation and
the next).
- At the end of run in, check the integrity of the gear.
