6. MAINTENANCE
(Continued)
● Pump
Turn off the tool, remove the power plug from the power outlet and wait until the unit has
cooled completely.
1. Loosen the screws on the back of the pump cover and remove the pump cover.
2. Remove the xing plate.
3. Clean the valve plate, xing plate and pump head with isopropyl alcohol.
Align the notch on the pump head with the corresponding notch on the valve plate.
Match the notch on the outside of the pump head with the one on the xing plate.
Mount the diaphragm so that it is smooth and taut.
● Replacing the heating element (heating core)
Turn off the tool, remove the power plug from the outlet and wait until the unit has cooled
completely.
1.
Remove the nozzle and element cover assembly with the nozzle changing tool and remove
the joint cover.
2. Loosen the screw at the back of the pump cover and remove the pump cover.
3. Remove the 6 screws from the handpiece (including 2 screws at the ange) and carefully
separate the housing.
4. Disconnect the heating element terminal and replace the heating element.
5. Assemble using the same procedure in reverse.
6. Calibrate the nozzle temperature.
Be sure to calibrate the nozzle temperature after replacing the heating element. Failure to do
this may result in a heater temperature that is much higher or lower than the previous one,
and can contribute to accelerated oxidation and/or wear of the nozzle, or premature failure of
the heating element.
