HYDRAULIC UNIT
BRemote Control Valve Lever
Move the lever to the "FORWARD" or "REARWARD"
position and hold. This will raise or lower the implement.
Lever will return to neutral when released.
A Do not hold the lever in the "REARWARD" or
"FORWARD" 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.
