Warm Up
Set the off/on switch to the “on” position and set
the 3M™ Scotch-Weld™ Hot Melt Applicator PG
II LT in the bench stand for approximately 15
minutes. During this warm-up period you may
note a slight dripping from the nozzle tip. This
dripping is due to expansion of the adhesive
during warm-up.
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.
Loading
Important
Use 3M™ Scotch-Weld™ Hot Melt LM Adhesives
only. Use of other adhesives may damage the
applicator or result in hazardous conditions.
After warm-up, load applicator with the 3M
Scotch-Weld Hot Melt LM Adhesive you’ll be using
on the job.
To do this, fully retract the Speedloader piston by
pulling one of the retract knobs located on either side
of the loading chamber. Insert up to three 3M Scotch-
Weld Hot Melt LM Adhesive Sticks into the chamber
through the rear loading port. The applicator is now
ready for operation.
Note
Do not depress trigger on the applicator unless
there is adhesive in the loading chamber. Damage
to the applicator may result.
As adhesive is extruded, the piston will move
forward. This will be visually evident by the forward
movement of the retract knobs. As the piston
approaches the front of the chamber, a whistling
sound will be heard. At this point the piston may be
retracted and another adhesive stick will fall into
place. The applicator is again ready for operation.
Adhesive may be loaded into the chamber via the
rear port at any time during operation thus saving
time and increasing productivity.
If it is desired to remove adhesive once it is in the
loading chamber, simply roll the applicator to one
side and then point up. This will allow the adhesive
to roll up and out of the chamber.
In order to keep the Speedloader stick feed operating
at maximum efficiency, the chamber should be
sprayed inside while the piston is in the full forward
position with 3M™ Silicone Lubricant or equivalent
once a week.
Application
Get a feel for your new 3M Scotch-Weld Hot Melt
Applicator PG II LT. Start by applying small
amounts of adhesive in puddles on a piece of scrap or
paper. Try feathering the trigger. The 3M Scotch-
Weld Hot Melt Applicator PG II is unique in this
respect. Pull the trigger back slowly and note a small
discharge of adhesive; pull the trigger back more and
note increasing adhesive flow. When the trigger is
fully depressed; you will get maximum flow. If more
or less flow is desired, refer to page 22 of this
manual.
Note
Do not operate the applicator without a nozzle
tip. Damage to the applicator may result.
