Operational Adjustments
• Prior to performing operational adjustments make sure air supply is off. Press down lever until wire
rope or chain is slack.
1. Close the up and down control valves (located on top of manifold) completely. Open them 1 full turn.
2. Turn the hook balance adjustment screw (13) counter-clockwise until the head of the screw is flush with
the top surface of the manifold body.
3. Turn on the air supply.
• When the wire rope or chain is winding, air is entering the unit through both the up and down flow
controls. Therefore, the down flow control also affects the up speed when it is set for a minimal down
speed.
4. To adjust the up or down speed, turn the corresponding control
valves:
• Counter-clockwise to increase speed.
• Clockwise to decrease speed.
5. Turn the hook balance adjustment (center screw) clockwise
until the empty handling device rises slowly. Back off the
adjustment until the empty handling device stops rising.
