Troubleshooting
9
Low or no adhesive flow
Problem
1. Hung adhesive stick
2. Low air pressure
3. No electricity
4. Dirty nozzle valve assembly
5. Regulator malfunction
(In order of priority)
Probable Cause
Turn on the 3M™ Scotch-Weld™ Hot
Melt Applicator PG II LT and allow it to
heat for at least 60 minutes.
With incoming air at 80 psi extrude
adhesive. If unsuccessful remove nozzle
assembly and extrude one stick of
adhesive. Readjust incoming air to
desired pressure.
Check to see if there is sufficient air
pressure. Test by setting pressure at 80
psi. Check in-line filter to ensure that it is
not plugged with contaminants.
Disconnect in-line filter from air hose.
Using a compressed air line, blow
compressed air through the filter in the
reverse flow position. If this does not
increase air flow through the filter, swivel
filter should be replaced.
Check to see that electrical service is
live, and that lighted switch is in “on”
position.
Remove nozzle valve and clean. Run
one adhesive stick out. Replace cleaned
valve assembly. This step should only be
done while tip is hot
Squeeze trigger and try to pull retract
knobs. If they can be pulled back easily,
install new regulator kit.
Contact with molten adhesive or hot
applicator tip or metal components
may cause burns. Wear heat-
resistant gloves and safety glasses
when operating or repairing the
3M Scotch-Weld Hot Melt
Applicator PG II LT.
