Maintenance
Under normal working conditions the indicator valve requires very little maintenance except inspection in connection with the normal cylinder cover overhaul.
Inspection of the Indicator Valve
1. Disassemble the indicator valve.
2. Check the valve seat and the cone for "burning through".
If the valve seat in the housing is "burned", the entire valve is to be replaced.
3. Clean and lubricate all components before remounting.
4. Ensure that the spindle is in "OPEN" position when assembling the valve.
