20. Reconnect air supply set at 30-40 psi maximum to help locate air leak.

21. Inspect connections and retighten if necessary. If air valve is leaking or air line going to end cap is leaking or has been damaged, replace with air valve assembly 62-9845-0009-0.

22. If air supply line has been punctured, cut or has been disconnected from air valve assembly, replace or reconnect air supply lines or replace with air supply line 62-9895-0005-3.

23. After inspecting, tightening loose fittings, or replacing parts, reassemble handle halves by following Reassembly Instructions. See page 37.


Condition 2:


Flow/No Audible Air

Leak

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 29. step 8.

If steady stream of air flows from the pierce tube, replace coupler filter 62-9895-0001-2. If no air flows from the pierce tube, proceed to next step.

17. By conducting the above tests, all problems other than the air valve assembly have been eliminated. Replace air valve/trigger assembly

62-9845-0009-0.

Note

If after replacing air valve assembly, the applicator fails to operate properly, contact your local 3M representative.


Condition 3:

Nozzle Drip

This problem may occur after a several day shutdown period because the material around the plunger in the rear of the cartridge has begun to cure.

This problem should be eliminated after a short period of use or when a new adhesive cartridge is introduced. If dripping continues, replace disposable nozzle (62-9845-0031-4).

Condition 4:

Slow Adhesive Shut Off

If after releasing the trigger on the applicator, adhesive continues to flow from the tip for a few seconds before shutting off, the air valve kit

(62-9845-0009-0) may need replacement. This can occur as a result of moist, oily or dirty air partially plugging the exhaust system.

Condition 5:

Applicator Will Not

Heat

Important

Troubleshooting steps should be conducted by a qualified electrician or service person.

1. Check electrical outlet. If no power, contact electrician; if outlet has power, proceed to next step.

2. Push on/off switch to “on” position indicated by visible red portion of switch. If no heat, proceed to next step.
