Charging/Discharging the Accumulator
Charging
1
Park the machine on level ground, lower the loader
arms, switch off the engine and chock all four wheels.
Release all hydraulic pressure in the accumulator by
selecting the starter key to the ON position without the
engine running, SRS ON and operating the loader arm
hydraulic lever.
2
Remove gas valve guard A and gas valve cap B.
3
Screw T handle C all the way out (counter clockwise)
before attaching charging tool (service tool 892/00948)
to accumulator gas valve.
4
Close bleed valve D.
Making sure not to loop or twist the hose, connect the
5
charging tool to the gas valve. Tighten to 1.0 lbf ft (1.36
Nm, 0.14 kgf m).
6
Connect charging tool to a bottle of compressed
nitrogen gas.
7
Screw T handle C all the way in (clockwise), this will
depress the core in the gas valve. Check charge
pressure which should be set to suit the loader and the
attachment fitted to the machine. For recommended
charge pressures refer to Technical Data - Smooth
Ride System.
8
If charge pressure is low, carefully open hand valve E
on the nitrogen bottle and SLOWLY fill the accumulator.
Close valve E when the required charge pressure is
reached on the gauge.
9
Let the pressure settle for 10 to 15 minutes. This will
allow the gas temperature to stabilise. If the charge
pressure is exceeded, with the gas bottle closed, open
bleed valve D. Reduce pressure as required, then close
bleed valve.
! CAUTION
To reduce pressure use the recommended charging tool
or the charge valve could be damaged which may result
in rapid discharge of the accumulator.

10
When complete screw T handle C all the way out
(counter clockwise) then open the bled valve D to vent
the hose.
11
Hold the gas valve to keep from turning, loosen nut and
remove charging tool.
12
Refit gas valve cap and valve guard.

before attaching charging tool (service tool 892/00948)
to accumulator gas valve.
4
Close bleed valve D.
5
Either connect charging tool to a bottle of compressed
nitrogen gas which is turned off or remove hose F and
fit a suitable blank on charging tool.
Screw T handle C all the way in (clockwise), this will
