• A minimum of 4.8 bar (70 psi) is required to operate the regulator. Do not use an air line lubricator.
1. Turn the pilot regulator screw counter-clockwise until 13 mm (1/2 in.) of thread is visible.
• The auxiliary flow valve is fully open when 3.2 mm
(1/8 in.) of screw head protrudes from regulator
body. Do not open beyond this point.
2. Adjust the auxiliary flow control screw by rotating
clockwise completely and then counter-clockwise 5
full turns, or until the screw head extends from the
regulator body 3.2 mm (1/8 in).
3. Adjust the trim valve by turning the screw clockwise
completely and then turning counter-clockwise 1
turn.
4. Turn both needle valves, located in the control
handle, clockwise until fully closed.
5. Attach heaviest load to load hook or handling
device.
6. Connect and turn on the air supply. Set supply line
regulator so that the unit receives a constant
pressure from 4.8 to 6.9 bar (70 to 100 psi).
7. Turn the E control handle to the hi-load position.
Turn the pilot regulator screw clockwise until the
heaviest load floats.
8. Turn the E control handle to the lo-load position. The load should not
lower.
9. Turn the lo-load needle valve, located on the handle, counter-clockwise
until the load lowers, and wire rope or chain becomes slack.
10. Engage lightest load with load hook or handling device.
11. Rotate lo-load needle valve clockwise until lightest load floats.
12. Rotate E handle to unload position. The lightest load should drift up.
13. Turn the un-load needle valve, located on the handle, counter-clockwise
until enough air is exhausted from the unit so that the lightest load
lowers and the wire rope or chain becomes slack.
14. Remove lightest load from load hook or handling device.
15. Rotate the un-load needle valve clockwise until the empty handling device
begins to float.
16. Rotate control valve to the three positions. Make sure the unit works properly.
Some fine turning might have to be done.
• If, for any reason, the pilot regulator must be readjusted, these needle valves will
have to be adjusted also.
Tandem Control Unit
Tandem Control Installation
1. Install master manifold (1) behind (E), (P) or (S) control kit, as shown in Dwg.
MHP1357.
2. Install slave manifold (2) to 2nd unit.
3. Install tandem hose assembly (10) between master (1) and slave (2) manifolds as
shown in Dwg. MHP1357.
