Manual Hydraulic
Sequence of Operation
1 With valves in neutral position, engine running hydraulic fluid is pumped through
valve bank and returned to reservoir.
2 Brakes, tail and steering are standard hydraulic cylinder operation.
3
Wrap cycle – push wrap valve in, detent will hold valve in position, fluid flows from valve
through flowcontrol and is split into 2 circuits, one circuit will go to ram cylinders and
the other will go to hydraulic motor. These circuits are proportioned with the lever on
flowcontrol valve. With the selector valve handle in “Both” position flow will go to cylinder
and motor. By changing flowcontrol handle, the cylinders will speed up or slow down
accordingly. At the same time motor will change speed inversely to cylinder ie. when
cylinder slows down motor will speed up.
4
Selector valve is used to bleed either cylinder or motor flow back to tank, or block both
circuits causing both cylinder and motor to operate. ie. With handle in wrap only position
the fluid that would normally go to the cylinder will flow back to tank. With handle in ram
only position motor fluid will go to tank.
5
Wrap cycle – pull wrap valve out, detent will hold valve in position, fluid will flow from
valve port causing cylinder to retract. Fluid from other end of cylinder will return through
check valve, at flowcontrol back through valve stack and to tank.
6
Check valve at motor lets motor freewheel in one direction without cavitating. Relief valve
at motor return acts as a restrictor valve to keep motor from turning when ram cylinder is
retracting.
