Conduct the following tests if there is NO audible air leak but the applicator heats.
1. Check air supply for a pinched line.
2. Remove applicator end cap by turning counterclockwise. Point the end cap away
from you and others in the work area, and pull trigger. A steady air stream
flowing from the pierce tube indicates air valve and air source are in working
order. Proceed to next step. If there is no air flow, proceed to page 28. step 8.
3. Replace and tighten end cap, turning it in a clockwise direction. Increases air
pressure to approximately 80 psi. If adhesive begins to flow, readjust to
desired pressure. If there is still no or low-adhesive flow, continue to next step.
