Raising
1. Before connecting the hydraulic hose, wipe the hose coupler clean.
Dirt in the hydraulic system can damage the cylinder o-rings and can cause leakage and
failure of the system.
2. Connect the hydraulic hoses, ensure the connections are tight. Visually check for leaks, binding, flattening,
kinks, or wear.
3. Open the ball valve on the hose connected to the cylinder.
4. Start tractor and idle at low rpm.
5. Engage hydraulic lever to power the cylinder.
6. Increase tractor rpm until desired rate of lift is reached.
7. Raise the conveyor to the desired height.
8. Close the hydraulic ball valve when the conveyor is fully raised.
Failure to close the ball valve may cause the frame to creep lower, potentially damaging
the conveyor.
Lowering:
1. Reconnect the hydraulic hose coupler to tractor, if disconnected. Keep the tractor running while lowering
the conveyor should the need arise to re-lift it.
Some conveyors are equipped with dual acting hydraulic cylinders, for these units the
tractor must be running to pump oil oil to the upper chamber of the hydraulic cylinder(s)
to prevent overfilling of the tractor reservoir.
2. Open the ball valve.
3. Open the tractor valve, feathering the control to prevent too rapid a descent.
Note
Once the valves are opened, the conveyor tube lowers by gravity. As the tube nears the full down
position, the rate of descent will increase. Do not operate with the tractor valve fully open.
4. Turn off the tractor, and lock out the tractor power source.
5. Before disconnecting hydraulic couplers, relieve the hydraulic pressure.
Disconnecting a hydraulic hose under pressure can result in serious injury.
5.3. Extendable Axle Positioning
Æ
When equipped with extendable axles:
Important
Do not raise the conveyor unless the axles are in the extended position. Do not transport the conveyor
unless the axles are in the retracted position.
Rollover can occur if axles are not extended before raising the conveyor.
1. Ensure the conveyor is on level ground before attempting to extend or retract the axles.
The conveyor must
be attached to tractor at all times.
