Before Operation
1. Make
sure
filtered
compressed air is available,
regulated to a maximum of 80 psi or to a
minimum of 40 psi.
DO NOT OPERATE 3M™
SCOTCH-WELD™ HOT MELT
APPLICATOR PG II LT BELOW 40 PSI.
If
low flow is experienced at 40 psi see page 9,
Troubleshooting.
2. Make sure that the 3M Scotch-Weld Hot Melt
Applicator PG II LT is plugged into 120 VAC and
that the switch is in the “on” position.
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
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.
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.
Note
If proper shutdown procedure has not been
followed (see Preventive Maintenance, "After
Operation," page 8), up to one hour heat up prior
to use may be required.
6. Under normal operations the in-line air filter
should be removed and cleaned every six months
(some air systems may require more periodic
changing). 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 9 through 19 for
Troubleshooting and Repair Procedures.
