1. First check whether the sprayer operates currently in dry grinding mode
where no water or air is sprayed by operating the change-over switch on it.
For more details, see the operating instructions.
2. Check the water/air hose line is in good connection in instrument panel. If the
hose line is in good condition, then check whether there is DC 24 V output at
water/air circuit solenoid valves;
if yes, the solenoid valve may be broken, and replace solenoid valve; if not,
measure voltage output at reserved port J33, if there is a voltage output,
replace treatm ent platform control board, if not, inspect the power supply in
side case.
3. Foot-operated micro switch:
Check whether the foot-operated micro switch resets norm ally;
if not, replace the micro switch.
4. Replace side case control board.
Inspections:
Generally, failure of program chair storage function is resulted from dam age to
angle sensor, replace the corresponding angle sensor.

Check air supply source and air filter,
clean or replace relevant components.
