Operating Continuous Flow Hydraulic Equipment - New Holland T7030 Operator's Manual

Operating Continuous Flow Hydraulic
Equipment
Continuous flow hydraulic equipment (e.g. hydraulic
motors) should be connected to the remote control
valve coupler with the feed hose (1) connected to the
upper coupler (4) and the return hose (2) connected
to the lower coupler (3) of the same valve.
Alternatively, the return hose may connected to the
low pressure return circuit (see page 3--91, 'Return
Oil Line').
The oil flow should be adjusted to regulate the motor
speed. If the flow is too high, the 3-point hitch and
other remote valves may slow down or stop.
Controlling the flow in this way will ensure that the
hydraulic system will only supply the oil required by
the motor.
With the remote control valve lever fully forward in
the float (F) position, the motor will be stationary. The
hydraulic motor will operate if the lever is pulled back
to the retract position (Lower). To stop the motor,
move the lever from the lower position to the float
position. In the float position the motor will be able to
stop slowly, which will not damage the motor.
IMPORTANT: When operating continuous flow
equipment, the remote control valve lever must not
be moved rearward to the neutral (N) or raise (R)
positions as damage to the equipment may result.
Select position 1 on the rolling gate to lock out the
neutral and extend services (see page 3- -76)
Observe the following to further protect the tractor
and equipment.
Do not open any bypass valve in the equipment
•
or motor. Adjust the oil flow through the valve to
regulate the rate of flow or speed of the motor.
To ensure optimum hydraulic oil cooling, operate
•
continuous flow equipment at the highest flow
setting and lowest engine speed that will give the
required machine performance and speed.
