Possible Corrective Action(s)
The green “POWER” switch does not light.
1.
Plug the unit in
2.
Set the “POWER” button in the “|” position
3.
Confirm that the fuse is functional

The system is running continuously without the
operator pressing the foot switch.
The system is in auto repeat mode (see section 6.2.6).
Press the stop button to stop cycling or press the mode
button to return to enter auto mode.
The system will not pressurize.
1. Confirm that the “AIR IN” is connected
2. Confirm that the air supply is 80-100 psi.
3. Confirm that the “DISPENSE ON” and
“DISPENSE OFF” fittings are properly connected or
plugged.
The syringe or cartridge is leaking adhesive between
dispense cycles.
Increase the “VACUUM” by turning the knob counter
clockwise. You will hear a louder hissing from the
“VACUUM EXHAUST” as it is increased.
Adjusting the “DISPENSE PRESSURE” does not
effect dispense quantity when valve dispensing.
The “DISPENSE PRESSURE” controls the pressure
supplied to the “DISPENSE ON” and “DISPENSE
OFF”. Dispense on controls the dispense pressure when
using a syringe or cartridge. For valve dispensing, the
dispense on and off control the valve actuation and
should be set at the recommended pressure for the valve,
normally 80 psi, and the dispense quantity will be
controlled using the reservoir connected to the valve.
The slide is advancing or retracting too fast or slow. The slide advance and retract rate should be set so that
the slide moves at a controlled rate. The factory default
is for the full slide stroke to take approximately 0.5
seconds. If this needed to be adjusted, see Section 6.7
for instructions.
