Check pressure of hydraulic
system
Pressure of the boom and auxiliary hydraulics are
measured from the auxiliary hydraulics
multiconnector. It is recommended to leave the
checking operation to qualified service technicians.
At minimum, a hydraulic pressure gauge with
appropriate measurement scale and a measurement
fittings are required. See picture for measurement
set up.
The main pressure relief valve for the auxiliary
hydraulics pump is located on a valve block at the
rear frame of the loader. However, the pressure of
the boom and auxiliary hydraulics is adjusted from
the boom control valve. The main pressure relief
valve must not be adjusted. If boom pressure can't
be adjusted high enough from the boom control
valve, the pump and main relief valve must be
checked. Contact Avant service.
WARNING
Risk of injection of hydraulic oil
-
Wrong handling of the
hydraulic system or wrong tools
can cause ejection of hydraulic
oil.
It is recommended that
pressures should only be checked
or adjusted by a competent and
experienced technician. Contact
your AVANT dealer if you need
assistance.
Never adjust pressure to higher
level than recommended setting.
The electric drive system is
designed to operate at the
intended pressure level. Other
settings can damage electric drive,
modify the response of the
controls, and decrease battery life.
Warranty will not cover for
damages caused by wrong
pressure setting. Never remove
tamper resistant seals from
pressure relief valves.
Pressure measurement from multiconnector
To measure the pressure, use the pressure gauge
adapter A422475.
Boom control valve
There is a pressure relief valve on the control valve
assembly. This is shown in the picture below. Adjust
boom and auxiliary hydraulics from this valve so that
the pressure gauge fitted to auxiliary hydraulics
outlet shows the correct pressure (18,5 MPa (185
bar)).
1.
Loosen and remove the locking nut
2.
Turn the adjustment screw below it with an
allen key.
Turn only with small increments, max 1/8
rounds at a time.
3.
Check pressure after each adjustment.
4.
Check pressure once again after tightening the
securing cap nut back.
Never attempt to adjust boom pressure from the
main pressure relief valve located at the rear frame.
Contact service if you suspect that the main pressure
relief valve might be damaged or wrongly adjusted.
