Remove the support list by pulling it upwards Expand the casing and slide the chassis towards the front After sliding the chassis all the way to the front, lift it upwards with front part first. Reassemble in reverse order.
3.2 Replacing the scaler handpiece tubing First remove cover and casing, see instruction section 1 Disconnect the handpiece wires, note the colors. From left: 1 - Blue, 2 - Red, 3 - Black and Green together, White at separate connector. Disconnect the water tubing (clear) from the magnetic valve (pos 2).
3.3 Measuring the voltages from the control circuit board to the scaler electronics unit Remove cover and casing, see instruction section Control Circuit Board Scaler Electronics Unit Measure the output voltage from control circuit board to scaler electronics unit. Pin 5-6 and pin 5-10 (see pictures above), reading should be 10 +/- 0,5 Vdc when running at working mode 3 and with foot control at maximum power.
Measure the power supply to the scaler pin 1-2. Reading should be aprox. 30 Vdc. If all measurements were as above, the control circuit board is functioning properly and giving the correct control signals to the scaler electronics unit. But the scaler electronic unit is probably malfunctioning and must be replaced, see Section 4.
Page 35
If applicable (CombiLED), dismount the left magnetic valve coil to access the mounting screw. Loosen all screws from electrical connectors and slide out the scaler electronics unit. Reassemble in reverse order.
3.5 Replacing the compressor First remove cover and casing, see instruction section 1. Disconnect the yellow air tubing. Cut the cable ties. Disconnect the electrical wires at the connector on the control board (note the polarity). Old Design Replace the compressor and reassemble in reverse order. Note that the compressor should not be in contact with the chassis to avoid vibration noise and short circuiting the connectors of the compressor.
3.6 Cleaning a magnetic valve First remove cover and casing, see instruction section 1. Magnetic valves function: 1: Polisher water 2: Scaler water 3: Polisher cleaning air 4: Polisher air Locate the valve according to picture above. Dismount the coil and the valve plug. Inspect and clean.
3.7 Opening a stuck waterline in the scaler handpiece First remove the scaler handpiece from the tubing. Set the water control ring to fully open (dot-dot). Gently insert the LM-ProPower Fixer tool into the handpiece from the connector side to open up the stuck water line.
3.8 Cleaning of clogged system in AirLED Connect a small tube approx. 40mm length to the powder outlet Fill the powder chamber with citric acid* up to the max level. Put it back on the unit and run the cleaning cycle. The air pressure will flow the citric acid trough the clogged tubing.
