G4 LIFTING PLATFORM ON A TRUCK BED
TRANSPORT
- See Section 2: LOADING / UNLOADING THE LIFTING PLATFORM.
G5 FREEWHEELING MODE
ACTIVATE
If the platform must be towed, follow the instructions below.
The platform may only be towed for a short distance and compulsorily by a machine with
significant braking power in order to be able to hold it using a connecting bar between both
machines.
1 – Chocking the platform.
2 – Hydrostatic declutching
Warning: before conducting this operation, take the necessary precautions: the machine will no
longer have any brakes.
- Lift up the bonnet.
- Screw in the hydrostatic pump’s HP restrictors1 (Fig. G5/1) up to the sticking point + 1 turn and
a half (No. 13 wrench and hex wrench).
3 - Mechanical declutching the rear axle
- Loosen the six lock nuts shown at 2 (Fig. G5/3) on the rear axle 1 (Fig. G5/2)
- Screw the bolts in the holes 2 (Fig. G5/3) up to the mechanical stop, following the pre-
defined tightening order: tighten bolt 2A a quarter turn; then tighten bolt 2B a quarter turn;
then tighten bolt 2C a quarter turn; then tighten bolt 2A a quarter turn (and so on until the
mechanical stop is reached). Do the same with bolts 2D - 2E - 2F.
Do not force the bolts to tighten further once they are at the mechanical stop.
Failure to follow this procedure of progressive alternating tightening may damage the axle.
Warning: after this operation, remember to release the mechanical anti-skid system. Follow the
predefined loosening order: loosen bolt 2a a quarter turn; then loosen bolt 2b a quarter turn;
then loosen bolt 2c a quarter turn; the loosen screw 2a a quarter turn (and so on). Do the same
with bolts 2d - 2e - 2f.
4 - Testing the axle brake
- Check the braking system by disconnecting the coil 3 (Fig. G5/4) on the hydraulic unit on the
chassis (to access the unit, remove the casing on the left-hand side of the chassis)
- Perform a translation movement.
The platform should not advance.
- After the test, reconnect the coil.
