- Proceed to switch off the machine (see: 1 – SAFETY INSTRUCTIONS AND ADVICE: DRIVING
INSTRUCTIONS WHILE UNLADEN AND LOADED).
- Chock the lifting platform in both directions on the axle opposite the wheel to be changed.

Recommendations
:
For using the MANITOU hydraulic jack Ref. 505507 and the MANITOU safety stay Ref. 554772:
- You are recommended to replace the rear wheels then, after turning the turret half a turn, to
replace the front wheels. This operation enables you to distribute the load on the axles by
positioning the counterweight on the axle opposite the wheel change.
- Unlock the nuts on the wheel to be changed.
- Set a jack under the axle housing as close as possible to the wheel and adjust the jack (Fig.
G2/2).
- Raise the wheel until it is slightly off the ground and place the safety stay under the axle (Fig.
G2/3).
One wheel weighs 300kg.
- Release the wheel by to and fro movements.
- Slip the new wheel over the hub.
- Screw on the nuts by hand, greasing them, if necessary.
- Remove the safety stay and lower the lifting platform with the jack.
- Tighten the wheel nuts with a torque wrench (see: 3 - MAINTENANCE: B - EVERY 250 HOURS OF
OPERATION for the tightening torque).
