6 MAINTENANCE
WARNING:
Hot Melt materials can cause severe burns resulting in disfigurement or blindness. Follow these
precautions before beginning any maintenance:
•
Wear protective clothing, safety goggles, and safety gloves.
•
Turn pump motor switch to off position. De-pressurize applicator(s) by triggering.
•
Unless stated otherwise, always allow melt unit to cool before beginning any maintenance.
•
Disconnect hose electrical connector when hose fittings are disconnected and power is off.
CAUTION:
To prevent damage to components (hose fittings, etc.), heat part(s) being serviced to approximately 121 °C
(250°F) prior to dismantling, assembling, or adjusting. Heat parts by applying power to the unit using a hand held hot
air gun or placing parts on a hot plate. Failure to do this will result in stripped threads and ruining both parts and tools.
CAUTION:
To avoid arcing of electrical contacts and possible failure of components, do not connect electrical
connectors when the hose power switch is on.

CAUTION:
For maximum performance and motor
life, do not allow pump motor to stall. A prolonged
stall condition will cause motor to go into thermal
overload.
5.3.3 Adhesive Flow Adjustment
Flow Control Valve
An adjustable pressure regulating device is mounted on the pump
under the melt unit chassis.
1.
Adjust adhesive flow with flow control knob [1] on right side of
melt unit.
2.
To increase pressure and adhesive flow, turn knob [1]
clockwise.
3.
To decrease pressure and adhesive flow, turn knob [1]
counterclockwise.
4. To achieve minimum pressure and lowest flow rate suitable
for application, turn knob fully counterclockwise. Gradually
turn clockwise until desired pressure and flow rate is reached.

DANGER:
To avoid personal injury, follow all
safety labels. Failure to properly operate and
maintain equipment can lead to serious injury.
•
Wear protective clothing, safety goggles and
safety gloves. Hot melt materials can cause
severe burns resulting in disfigurement or
blindness.
•
Use only manufacturer recommended materials
in this system. Fire, explosion, personal injury,
property and equipment damage can result if
improper or unsafe materials are used.
•
Disconnect electrical power from external
source to melt unit before undertaking
maintenance or troubleshooting. Failure to
disconnect power can result in fatal electrical
shock.
•
Depressurize system before performing any
maintenance to pump, pump filter, flow control
valve or hose. Turn pump switch off and
depress trigger on handgun until there is no
flow. Air trapped in the system or in a
component can form a pressure pocket.
Loosen fittings cautiously. Adhesive under
pressure can cause severe burns and
blindness.
•
Always read the manufacturer’s recommended
use of the material.
5.2 Startup Instructions
1.
Become familiar with Section 5.1, Controls and Indicators.
2.
Install melt unit as specified in Section 4, Installation.
3.
Fill tank with hot melt material.
4.
Turn melt unit on and allow sufficient warmup time for hot
melt material to thoroughly melt.
5.
Align motor on receipt of a new unit or after transportation.
a.
Loosen four screws holding motor pan to side of melt
unit.
b.
Heat melt unit and run motor. This centers the motor.
c.
With motor running, tighten four screws in a crisscross
pattern.
6.
Set hose and tank temperatures to desired settings. Lower
settings increase pot life of the material. Materials degrade
over time due to oxidation.
7.
To prevent motor stalling, adjust flow control valve to the
minimum flow requirement.
