•
Look carefully how the 4 articulation pins, rollers, bolts and nuts on the platform hands are mounted. Then dismount them. (If you
have used the platform to mount the lift frame, you have just mounted the pins of the lift arms in previous steps, and they s houldn’t
be dismounted anymore.)
•
Raise the platform (by hoist, overhead crane, fork lift with slings etc.) and position it above the lift arms.
•
Align the platform hands with the holes in the lift arms.
•
Mount the pins in the same way as originally supplied. Fasten the bolts and nuts with the required torque.
•
Tilt the platform open to 45° angle. Align the hole in the tilt cylinders with the hole in the platform hands by means of the electrical
controls, or manually [see procedure above].
•
Mount the pins of the tilt cylinders. The rollers are mounted and the bolts are fastened after the adjustment of the stroke of the tilt
cylinders. (see 10.2 on page 40).

Pressurise the lift and tilt cylinders gently. Stop as soon as you hear the hydraulic system turn in overpressure.
CAUTION
•
To OPEN the platform, most tilt cylinders are powered in by powerful internal springs (*). The piston rods will react quickly and
suddenly when releasing the hydraulic pressure.
(*) Exception: in case of option OAH026, the tilt cylinders are powered in by means of hydraulic pressure (power open).
