3. Maintenance
The dispenser has been designed and constructed as a precision tool and will provide
maintenance-free operation under normal conditions. The unit should be kept free from
dirt and dust and should not be exposed to moisture. The cartridge adapters should not be
fouled by the dispensed medium.
4. Troubleshooting
Material fails to flow:
- Check the compressed air connections of the unit and the cartridge. Ensure that the
pressure regulator is turned on and that the pressure gauge shows the desired pressure.
- Ensure that the correct supply voltage has been selected. Check that all electrical
cables are correctly connected and that the unit is on.
- For units with timer control, check that the time setting is not 00.00 sec.
- With high viscosity media check whether the selected pressure is sufficient or the
dispenser needle has dried up.
Incorrect quantity is dispensed:
- Change the setting of the pressure regulator.
- Use a dispensing needle with a different diameter.
- For units with timer control, change the timer setting.
- The first dispensing pulses after a cartridge change can produce different amounts of
material.
Air noise can be heard:
- Turn the vacuum off and then on again to test whether the noise is being caused by
the vacuum function.
- Isolate the compressed air supply and check that all hose couplings are correctly seated.
Material dripping:
- Check the contents of the cartridge for trapped air.
- Use a pointed plastic needle instead of a needle with a metal nozzle.
- Use a larger needle diameter with a lower pressure setting if possible.
- Increase the setting of the anti-drip vacuum.
