6. Maintenance and Precaution：
The dispenser is designed and built to be relatively maintenance free. To assure trouble free operation, the following
recommendations should be followed：
a. Make certain air supply is clean and dry.
b. Avoid turning barrels upside down or laying barrel so that material may run through air line to internal
components.
c. Avoid turning the vacuum to large and cause the generation of bubbles in the material or the material to run back
into the system.
d. If the piston inside the barrel is running up and down during the dispensing, it is mean the material has really high
viscosity and you will need to replace the piston with red or rigid piston.
e. Avoid connecting the unit to excessive moisture or solvent saturation.
f. Avoid connecting air supply exceeding 7 kg/cm2 (100 psi) and 2 kg/cm2 (30 psi) for low pressure dispenser.
g. Use only Amyl Alcohol to clean outside surface of the main housing.
h. Please take off the barrel with needle after use and rinse through solvent. If you want to save the barrel for further
use, please take off the needle and replace with safety tip (optional) or place the barrel on the barrel stand to
prevent solidification.
7. Troubleshooting：
Problem Possible Cause Correction
Indicator or
display does not
light
• no power input
• PCB main board damage
• check power cord connection
• turn on power
• replace new PCB main board
Cannot dispense • foot pedal not plugged in properly
• defective foot pedal
• foot pedal port broken or loosen
• defective Solenoid Valve
• check connection
• foot pedal needs to be repaired or replaced
• remove the cover and check for broken or
loosen
• replace the valve and make sure you use
the appropriate piston and do not turn the
vacuum too large
System will not
pressurize
• Insufficient air pressure
• air pressure connector not plugged in
• regulator defective
• increase air supply pressure
• check connection
• replace pressure regulator
System will not
pull vacuum
• vacuum setting is too low
• barrel piston not appropriate
• adhesive too watery or full
• increase vacuum volume
• replace with appropriate piston
• replace with different adhesive and fill only
3/4 full in the barrel
Inconsistent • air bubbles in adhesive • decrease vacuum setting and de-bubble
