CAUTION
To reduce the risks associated with hazardous work positions,
which if not avoided, could result in minor or moderate injury:
• Avoid raising the elbow, bending the wrist, reaching, and
bending over when using this device.
General Information
Thumb pressure on the feeder pushes the adhesive stick into the
heat block. The adhesive is melted by the heat block and pushed
out through the tip. A fixed thermostat on the heat block
maintains heat block temperature.

CORRECTION
Check to see that 220-240Vac service is on. Thermal fuse in the thermostat may have blown.
Allow the applicator to heat up for at least 30 minutes.
If the applicator was left on overnight, the tip may be plugged. This may block adhesive
flow and cause backmelt.
CAUTION
Do not force adhesive. Excessive force can damage the
applicator and cause molten adhesive to flow out the rear.
4. Gently press the feeder forward and push the adhesive into
the heat block. Melted adhesive will flow from the tip.
WARNING
TIP AND VALVE ARE HOT. KEEP TIP POINTED AWAY FROM
BODY PARTS.
NOTICE
To avoid charring or plugging of the tip, extrude at least one
adhesive stick every three hours that the applicator is turned on.
Shut-Down
1. Unplug the applicator.
2. Extrude one adhesive stick to cool down the applicator.
Preventive Maintenance
CAUTION
Avoid contact with hot adhesive and applicator tip. May cause
burns. Wear Personal Protective Equipment (PPE) per workplace
and industry standard operating practices and procedures when
using and cleaning or changing tip. KEEP TIP POINTED AWAY
FROM BODY PARTS.
To maintain proper operation, follow these steps.
1. Inspect nozzle tip daily. Make sure it is clean and clear of
foreign matter.
2. Keep the adhesive clean and free of airborne contaminants.
