UNLOCKING THE OVERHEAD GUARD OR THE CAB:
- Unlock the overhead guard by means of the lever 1 (fig. H3/1) in position A.

UNLOCKING THE LIFTING CYLINDER
- Access the driver's cab lifting cylinder feeding screw via the access panel underneath the lift
truck and loosen it.
Dispose of the drain oil in an ecological manner.
RAISING THE OVERHEAD GUARD OR THE CAB:
Check that there is nothing laying on the driver’s seat, which could disrupt the operation.
- If necessary, raise the mast until it is approximately 50 cm above the overhead guard or the cab.
- Unscrew the two screws 2 (fig. H3/2) on the roof and replace them with two MANITOU eyes 3
(fig. H3/3) Reference 72422.
- Pass a sling 4 around the mobile upright’s upper belt and fasten the ends of the sling onto the
eyes 3 (fig. H3/3).
- Switch on the engine.
- Gently raise the mast to tension the sling and raise the overhead guard or the cab a few
centimeters.
- Return the lever 1 (fig. H3/1) to its initial position (position B).
- Tilt the mast forwards and raise it slowly until you can insert the safety stay 5 (fig. H3/4).
Completely fill the hydraulic lift pump, bleed the lift cylinder and tighten the lift cylinder feeding screw.
- Lower the mast to release and remove the sling.
