SETTING THE APRON AND PUSHOFF VALVE
The manifold block containing the pushoff sequence valve cartridge and apron sequence valve cartridge is used
to control two hydraulic circuits with one hydraulic remote. when the tractor hydraulic remote is activated, oil flows first to
the apron cylinders until they are fully extended. Once the cylinders are fully extended, the apron circuits’ hydraulic
pressure begins to increase. Once the pressure threshold is surpassed (which is adjustable. See adjustment section),
the sequence valve diverts the oil flow to the pushoff’s hydraulic circuit. Once the push off is completely extended the
operator then reverses the tractors hydraulic remote. The counterbalance valve will hold the apron open until the push off
is fully retracted. The Apron sequence valve then opens and allows the apron to close.
Setting the valves:
STEP 1 PUSHOFF SEQUENCE VALVE
Loosen the lock nut (9/16”) on the sequence valve cartridge. Turn the setscrew (4mm) clockwise until the front
apron rises before the push-off begins to advance. (Earthmover should be empty) Turn the adjustment screw an
additional 1/4 turn clockwise and tighten jam nut.
STEP 2 Counter Balance VALVE
Loosen the lock nut (9/16”) on the counterbalance valve cartridge. Turn the setscrew (4mm) counter-clockwise
until the apron holds in a raised position while rear gate is being retracted. Turn adjustment screw an additional 1/4 turn,
tighten jam nut. DO NOT tighten adjusting screw more than necessary.
