Manual Valve Option With Cooler
316-282A
Manual Valve Option With Cooler
Refer to Figure 3-3:
The manual valve is equipped with a spring return lever
for changing flow through the hydraulic lines that are
attached to the front loader attachment. With this
arrangement, the tractor power take-off can remain
running. The valve, when in neutral, dumps hydraulic
fluid back to the tank allowing the pump to run
continuously. It also opens when the pressure becomes
too high dumping fluid back into the tank.
An oil cooler with a temperature switch that turns the
cooler on when oil temperature reaches 140
o
F is
included to protect against overheating. The control box
will power the oil cooler.
This valve is particularly good for hydraulic cylinders on
equipment such as log splitters. It is not recommended
for operating equipment designed for continuous
operation such as hydraulic motors.
Solenoid Valve Option W/ Cooler
316-280A
Solenoid Valve Option With Cooler
Refer to Figure 3-4:
The solenoid valve is electrically activated from a control
box mounted near the operator or remotely located for
operating while standing near the equipment.
An oil cooler with a temperature switch that turns the
cooler on when oil temperature reaches 140
o
F is
included to protect against overheating.
The control box has one toggle switch for power on, one
for momentary operation, and one for continuous
operation.
Push and hold the yellow toggle switch to move a
hydraulic cylinder rod. Pull and hold the toggle switch to
move the cylinder rod in the opposite direction. Release
the toggle switch to stop cylinder rod movement.
Push blue toggle switch on to run hydraulic motor in one
direction. Pull blue toggle switch on to run hydraulic motor
in the opposite direction. Manually return toggle switch to
neutral (center) position to stop hydraulic motor
operation. The solenoid valve, when in neutral, dumps
hydraulic fluid back to the tank allowing the pump to run
continuously. It also opens when pressure becomes too
high dumping fluid back into the tank.
