3 Filling the HSRX Sys-
tem with Oil The HSRX System is factory tested and delivered
completely assembled and filled with oil
. The System oil
capacity is approximately 0.9 litres of oil .
1.Refer to Section 8.8 Recommended Oils and Lubricants .
2.All oil should be filtered to prevent the ingress of
contaminants.
3.When the Jet and Pump are first run the oil level will
drop rapidly in the Reservoir. To avoid the Pump
running dry, the system should be filled as full as
possible before the Jet and Pump are run.
FILL THE OIL COOLER:
Refer to Hose Connection Schematic shown in Section 8.5.2
HSRX Controls Servicing Details, Figure 28: HSRX Hose Con-
nection Schematic
.
Ensure that the Pump is empty of oil.
1. Disconnect the HSRX Cylinder to Cooler return Hose [H2]
AT THE COOLER Return Port end.
2. Disconnect the Feed Hose [H3] to the Oil Cooler AT THE
PUMP and ensure the free end remains higher than the
Cooler Return Port.
3. Place a funnel in the Cooler Return Port and, ensuring air
can escape, fill the Cooler.
4. Reconnect the hoses [H2] and [H3] to the Pump and Cooler
keeping the system as full of oil as possible.
FILL THE OIL PUMP RESERVOIR:
Unscrew the Filler Cap on the top of the Pump Reservoir. (
The Filler Cap is fitted with an integral Dipstick). Insert a
funnel and fill the Reservoir with oil to the 'MAX' Dipstick
mark.
The JHPU should now be run to purge air from the system.
It
is important that this is carried out as shown in Section
8.5.2 HSRX Controls Servicing Details.
C

the HSRX system and when the Jet
and Pump are first run, the oil level
will drop rapidly in the Reservoir. To
avoid the Pump running dry the sys-
tem should be filled as full as possi-
ble before the Jet and Pump are run.
