3M Scotch-Weld Owner's Manual - Caution:
Before Operation
CAUTION:
Always remember the tip and valve are
extremely hot.
1. Make sure filtered compressed air is available,
regulated to a maximum of 80 psi or to a
minimum of 50 psi. DO NOT OPERATE 3M™
SCOTCH-WELD™ HOT MELT APPLICATOR
PG II BELOW 40 PSI. If low flow is experienced
at 40 psi see page 8.
2. Make sure that the 3M Scotch-Weld Hot Melt
Applicator PG II is plugged into 120 VAC and
that the switch is in the “on” position. Switch
should light up.
3. Inspect nozzle tip daily. Make sure tip is clean
and clear of foreign matter. Using a coarse cloth,
wipe off any accumulated adhesive or other
foreign matter on the tip.
CAUTION:
Valve and nozzle tip are extremely hot. Wear heat
resistant gloves when cleaning tip.
4. Be sure there is adhesive in the loading chamber.
5. Under normal conditions, allow at least 15
minutes for the applicator to warm up.
6. Under normal operations the in-line air filter
should be removed and cleaned every six months.
Simply remove the filter from the air supply line
and blow compressed air through the filter in
reverse of normal air flow to remove particular
matter.
7. Periodically inspect the applicator to ensure that
assembly is proper (i.e. watch for loose screws,
worn pins, etc). See page 8-14 for
Troubleshooting and Repair Procedures.
NOTE: Before shutting down the 3M Scotch-Weld
Hot Melt Applicator PG II put the electrical
switch in the “off” position. Continue using the
applicator until approximately one adhesive stick
has been consumed. If 3M Scotch-Weld Hot Melt
Applicator PG II has not been in use but still on
heat prior to shut down WITHOUT EXTRUDING
ADHESIVE, allow at least one hour for heat-up.
