1. Cut or disconnect truck’s main hydraulic pressure line and install the diverter valve
in series using the “IN” and “OUT” ports.
2. Connect the “T” port on the diverter valve to the truck’s hydraulic tank line with an
appropriate size line to handle the full system flow.
3. Connect the “P1” port on the diverter valve to the “IN” port on the hand valve.
If installing dual lifters, connect the “P2” port on the diverter valve to the “IN” port
on the other hand valve.
4. Connect the “T1” port on the diverter valve to the “OUT” port on the hand valve.
If installing dual lifters, connect the “T2” port on the diverter valve to the “OUT”
port on the other hand valve.
5. Connect the “A” port on the hand valve(s) to the “UP” port of the rotary actuator(s).
6. Connect the “B” port of the hand valve(s) to the “DOWN” port of the rotary
actuator(s).
7. Disassemble each hose clamp assembly and position weld plates where needed and
weld in place.
8. After the weld has cooled, paint the weld plates to match the truck color.
9. After the paint has dried, reassemble the hose clamp assemblies around the hoses.
V. Adjusting relief valve settings:
The diverter valve ( 1 ) ( figure I-4 ) supplies the cart lifter hydraulic system
with approximately 2 GPM of oil flow. This diverter valve is equipped with a
full system relief valve ( 4 ) set at 2500 psi, to protect the truck’s hydraulic
system from any blockages that may occur down stream of the diverter valve.
The diverter valve also includes a lifter circuit relief valve ( 3 ) set at 2300 psi,
to prevent the diverter valve from shutting down if a blockage occurs in the lifter
circuit. There is also a relief valve ( 5 ) set at 1800 psi in the hand valve ( 2 ) to
protect the lifter from excessive pressure. These relief valves are preset from the
factory to operate properly on most trucks with a system pressure between 2300
and 2500 psi without any adjustment. However, if any adjustment is necessary,
follow these instructions.
WARNING :Bayne equipment is rated for a maximum pressure of 3000 psi.
Operation at pressures above 3000 psi may damage equipment and cause
personal injury. In order to avoid injury and maintain manufacturer’s warranty
never operate above 3000 psi.
