Checking the operation of the maximum pressure valves
With the frequency indicated in the general chart, check the operation of the
maximum pressure valves of the distributor.
To test them, connect two pressure gauges with a full scale of 250 bar to the
pressure outlets (4 and 5).
Checking the general maximum pressure valves of the system (1 and 2)
The pressure gauges relating to these valves are those connected to the outlets
4 and 5.
a)
Start the internal combustion engine.
b)
Perform the movements of the stabilisers until the limit switch has been
reached and keep them in this position for a few seconds. This activates
the maximum pressure valve of the circuit.
c)
Read the pressure on the gauge, which should be 200 bar ± 5 bar
Checking the maximum pressure valves relating to lifting (3)
The pressure gauge relating to this valve is the one connected to outlet 4.
d)
Start the internal combustion engine.
e)
Press the platform "up" button (
13
) until it reaches the limit and hold it
down. This activates the pressure relief valve of the lift circuit.
