L3FX: Slow Refill
To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.
- Check the air filter by removing the quick turn cap on top of the funnel. Clean or replace if needed.
- Remove the funnel cover and inspect. Remove stuck debris if needed. Ensure level sensor sight tube is clear of debris.
- Verify level sensor readings on diagnostic screen are consistent and slowly increase as material is dispensed.
- Verify air supply to the system is strong and between 50 and 100 psi (80 to 100 psi is preferred).
- Inspect the air line and vacuum tubing to the feed bin. Dips or kinks in the vacuum tubing can lead to a blocked flow path.
- Check the number of pump cycles in between refills (8 to 10 cycles is desired). Short fills of 3 or fewer cycles can be caused by a clogged funnel filter or debris in the funnel.
- Monitor pellet flow and time to refill. Refills in excess of 15 seconds can be caused by low adhesive level in feed bin, insufficient air pressure, restricted feed hose, or clogged funnel filter.
- Verify size and shape of adhesive being fed is compatible with feed system and that melt rate ability is not exceeded.
- Check if glue is excessively dusty or releases oily vapor when heated. Fill system maintenance will be minimal given typical glue selection.
