4.5 Clearing Paint Supply Lines
Determining Clog Location
If a paint line becomes clogged, the primary and
secondary filter drains are used to determine the
approximate location of the clog. Use the follow-
ing procedure to determine the location and clear
the clog.
Step 1:
Check for paint flow a secondary filter.
• Place a bucket below the secondary paint filter
near the carriage.
• Slowly open the drain valve and check for flow.
• If paint flow is good, the clog is between the
secondary filter and the spray gun. Close the
drain valve and proceed to step 2.
• If there is little or no flow, the clog is at the
secondary filter or between the paint tank and
secondary filter.
• Follow the Cleaning Paint Filters procedure to
clean the secondary filter.
