6.2.17 Checking the seal of the cylinder check valves
Warning: this operation must be performed only by qualified technicians trained

6.2.17.1 Checking the seal of the stabiliser cylinder check valves
At the frequency indicated in the general chart, check the seal of the valves
flanged on the stabiliser cylinders.
To perform this check, it is necessary to:
1) Place the machine as shown in the figure (platform completely lowered
and stabilised on the stabilisers, with the cylinders extended not to the
mechanical limit switch)
2) Make sure that, even after 4 hours, the machine remains in the position
where it was left and that there were no movements due to oil leaking
from the valves (because of a malfunction or impurities trapped in the
cursor). Manually check that each stabiliser has remained firmly on the
ground.
