HECKING THE OPERATING PRESSURES IN THE HYDRAULIC SYSTEM
A pressure gauge, with a minimum scale of 250 bars, must be used to carry out this check.
‑
Make sure that the machine is closed and in the resting position.
‑
Make sure that no one is standing within the machine operating range.
‑
All the specified checks must be carried out from the control position in the basket.
a) Connect the pressure gauge to the pressure intake on the aluminium delivery manifold
block located in the proportional valve compartment (see photo).
First connect fitting MB (ref. Hydraulic system).
b) Go to the control position and switch the machine on.
c) Close one of the two right stabilisers completely and maintain the movement activated.
Read the pressure value. This value relates to the right track distributor.
Switch the machine off.
d) Connect the pressure gauge to fitting MA (ref. Hydraulic system).
e) Go to the control position and switch the machine on.
f) Close one of the two left stabilisers completely and maintain the movement activated.
Read the pressure value. This value relates to the left track distributor.
g) Stabilise the machine.
h) Set the second arm cylinder to the FOLDING mode.
