Safety information WARNING Before do any check and maitanance work in the pilot valve Must be sure all air is drained out of tank and power is disconnected Failure to do so may result in injury or equipment damage Identifying The Problem If your pilot valve is malfunctioning read the following symptoms and solutions before attempting to adjust the valve If you simply want to change the setting of your pilot valve go directly to the adjustment procedure Symptom 1 The pilot valve loads unloads in a rapid fashion creating a chattering sound or it will not maintain an unload setting One of the following may be true 1 Excessive vibration can cause the valve to load unload improperly To check put on a glove or other hand protection and grip the pilot valve tightly while cycling the compressor If the compressor loads and unloads correctly during operation vibration is causing the problem To correct this raise the load pressure 1 PSI and the unload setting 3 PSI using the techniques shown in steps 8 and 9 of the pilot adjustment sec tion 2 The pilot valve s filter could be plugged or clogged To check the filter s condition remove the pilot valve from the tank or line Remove the nut from the bottom of the valve completely Pull out the two screens and the filter pad If the filter is blocked you need to get a felt replacement After cleaning the filter area replace the screen the filter pad and then the other screen Comp
