- Check the status of the hydraulic oil filters; there is an indicator
to show this, change the cartridge if the visible indicator appears.
- Check the degree of usage of the articulated axles.
- Check the main safety items:
- When the machine is powered up, all of the indicator lights should
light momentarily
- Tilt: with the machine unfolded, tilt the support panel beyond an
angle of 4°, at which point the alarm will sound, and any lateral
movements or extension of the telescopic arms will be prohibited
- Speed limiter: only slow speeds are possible if the arm or fly jib
are raised, the telescopic arms extended or if the suspension plat-
form is beyond the horizontal
- Check and if required readjust the setting of the connection point
(see the procedure in chap. 4.4.1.3, page 32)
- After a complete deployment of the arm and fly jib of the machine,
the error indicator should remain unlit
