Hydraulic Drive Operation
Hydraulic Drive Operation
Drive Operational Requirements
Hydraulic System:
Closed Center, pressure compensated or load sensed
systems only
Drive will not operate on Open-Center hydraulic systems
Electrical System:
Tractor Hookup
Hydraulics:
1.
Connect pressure hose (P) to retraction outlet
2.
Connect motor return hose (T) to motor return port (if
available) or to extension outlet.
3.
Set flow rate at maximum required flow of 13 gpm.
4.
If tractor is equipped with electro-hydraulic valves,
set timer to “constant” flow.
Electrical:
Power must be connected directly to the battery. Make
sure that eyelets are properly connected (red to positive,
black to negative). Connect female socket to power port
adapter.
Disconnect all cables and remove VER-21568 Ext. Control
module before welding on drill.
Minimum Hydraulic Pressure
2250 psi
Maximum Hydraulic Pressure
3000 psi
Maximum Required Flow
8.5 gpm
Voltage
12 volts DC
Current
4 amperes
High Pressure Fluid Hazard:
Escaping fluid under pressure
can penetrate skin, causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.
Moving Chain Hazard:
Return hydraulic drive circuit lever to
Neutral before exiting tractor cab. Unexpected drive rotation
can cause serious injury.
