Troubleshooting
Problem Probable Cause Correction
1. Low or no No heat Check to see that 120 VAC service is on. Thermal fuse in the
adhesive flow thermostat may have blown. Use Repair Kit #9262.
Shutdown procedure was not observed Allow the applicator to heat up for at least 30 minutes.
Plugged tip If the applicator was left on overnight, the tip may be plugged.
This may block adhesive flow and cause backmelt. CAUTION:
Do not force adhesive. Clear the tip with a small nail or paper
clip. Extrude the remaining adhesive stick and one new
adhesive stick to clear the opening.
Backmelt Remove the clip and feeder from the track of the applicator.
Push the existing adhesive stick into the white sleeve
approximately 3/4’’ with a new adhesive stick. Remove the new
adhesive stick before it melts and look into the white sleeve.
Look for a thin skin of adhesive around the inside of the white
sleeve. Scrape this skin toward the heat block. CAUTION: Do
not damage the white sleeve. Extrude one adhesive stick to
clear the sleeve.
TO AVOID BACKMELT: Observe the Start-Up and Shut-Down
procedures. Do not force adhesive through the applicator.
2. Dripping* Nozzle Backmelt Refer to preceding paragraph on backmelt.
Worn Valve Assembly Replace valve with Repair Kit #9234
Contaminated adhesive Keep adhesive clean and free of contamination.
*Thermal expansion may cause some dripping during start-up. This is normal.
