Preventive Maintenance

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.
