SECTION 3 -- FIELD OPERATION

It is recommended that a temperature gauge,
where available, is installed in the remote circuit
when using hydraulic motors for continuous
operation. If over-heating occurs, stop the
hydraulic motor until the oil cools. Ensure the flow
control setting is at maximum and the engine
speed at a minimum, appropriate to machine
performance.
If operating conditions are normal and high
temperatures persist, install an oil cooler in the motor
return circuit. The maximum recommended
operating temperature of the oil is 110
°
C (230
°
F).
Your authorised dealer can supply a suitable oil
cooler and the necessary fittings or make the
installation for you.
Operating Several Remote Valves
Simultaneously or Remote Valves and
Hydraulic Lift Simultaneously
NOTE: The hydraulic load-sensing system on your
tractor adjusts the oil flow according to the individual
flow control settings up to the maximum output
possible, dependent upon engine speed. The oil flow
will be relatively constant in the remote control valve
circuits if the flow control valves are used to regulate
the flow, thus providing constant operating speed for
hydraulic motors, etc., even if engine speed varies.
Maintain the engine speed above the minimum
required for simultaneous operation of all the
required circuits and vary ground speed by selection
of the appropriate gear ratio.
If operating two or more remote control valves
simultaneously or remote valves and the hydraulic
lift, all the flow control valves should be adjusted to
provide a partial flow. If not so adjusted, all the
available flow may be directed to the full flow circuit
when the pressure in that circuit is less than that of
the other circuits in use.
Bleeding Remote Cylinders
When connecting a cylinder with trapped air, i.e., a
new cylinder, one that has been out of service or one
that has had the hoses disconnected, it will be
necessary to bleed the cylinder to remove the air.
With the hoses connected to the remote control valve
couplers at the rear of the tractor, position the
cylinder with the hose end uppermost and extend
and retract the cylinder seven or eight times using the
remote control valve lever or joystick.
Check the rear axle oil level before and after
operating a remote cylinder.
