VALVE CLEANING INSTRUCTIONS
Occasionally pieces of scale or rust from the air line will become lodged under the rubber seats of the air valve causing
air leakage. This leakage is easily detected since lift will raise slowly when you connect the air line to the quick coupler
inlet even though the valve lever has not been touched. If this occurs, the "in" side of the valve needs cleaning. The lift may
also lower slowly when you disconnect the air line from the quick coupler even though the valve lever has not been
touched. If this occurs, either the "in"or both sides of the valve need cleaning. To clean refer to valve diagram and follow
these instructions:
A. Remove the adapter (2) from the inside of the air control valve. Inspect screen one for foreign particles and clean
as required.
B. Remove the valve from the body by pushing on stem (8) (from the center toward the outside of valve) with a piece
of stiff wire or nail.
C. Carefully examine the valve seat (6) for any scale, dirt or foreign matter. If foreign matter is embedded in the
valve seat, remove the screw (4) and cap (5) from the end of spool (8) and clean the seat (6), turn over and
reassemble.
D. Lubricate the valve spool with light chassis grease.
E. Reassemble the valve in this order:
1. Insert the valve spool.
2. Insert spring.
3. Assemble hexagonal nut into body.
The valve should now operate like new.
