57HYDRAULIC UNIT
BRemote Control Valve Lever
The remote control valve lever directs pressurized oil flow
to the implement hydraulic system.
[Example: Installing triple segment valves]
A Do not hold the lever in the "pull" or "push" position
once the remote cylinder has reached the end of the
stroke, as this will cause oil to flow through the relief
valve. Forcing oil through the relief valve for extended
periods will overheat the oil.
A When using the tractor hydraulic system to power front
loader, do not operate boom and bucket cylinders
simultaneously.
A Connect the pressure of load side of implement
cylinders to ports [B], [D] or [F] which have built in load
check valve to prevent leak down.
A To use the single-acting cylinder with the float valve,
connect this cylinder to the [B], [D] or [F] port.
To extend a single-acting cylinder, pull the remote
control valve lever rearward. To retract a cylinder,
push it fully forward to the "FLOAT" position. Do not
hold it in the down position, the transmission fluid may
be overheat.
