When the dental equipment goes wrong, the clinic's business will suffer. In order to guarantee the smooth running of your business, this tutorial will guide you how to deal with common problems of the dental chairs.

The high and low suction can’t work, the low suction have little power after a period time using

1.There is some wrong for the pipeline connection
2.Wastes block the pipelines
3.Micro-switch is not high sensitivity, and the spring is pressed into damage or the pylon box hole size is not in the right position
4.Wastes block the low suction assemble-waste cup
5.the low suction assembly is blocked by wastes
6.It blocks the pipeline because of the poor quality water Solutions: replace the spare parts which can not be repaired, inspection and repair lines, cleaning low suction valve, proposing the user clean assemble-waste cup on a regular basis(once a two-week cleaning), use 3-way syring blowing washed then back as it is , maintain tube smooth,

Treatment machine set a dysfunction

1.Main line and motor line connection error
2.Mask or controller is bad
3.Auto-reverse switch is bad or or welding error
4.Foot-controller switch is bad
5.The core conversion wire location is wrong

Operation light is not shine or meet other problem

1.Bulbs are burn-out
2.Connection of the two tie-in-touch bad and the connection is loose
3.Public lines has not penetrated relay which is be controlled
4.The inner wires in the movable joints are twist off
5.The reflective film of operating light has came off
Solutions: replace bulbs in the same model, turn off the power then check and connect the plug. We advice the user should maintain the operating light tape under the normal temperature and use of the soft fabric dab it but the lamp back can not be rubbed, must replace the reflective film.

Hot water cup can not heat up or the water temperature is too high

1.The power or the wires are abnormal
2.Public lines of temperature line for cup hot water are in wrong connection
3.Temperature-controlled machine or the hot rods of hot water cup have been bad
4.Controlled-mask have been bad
5.The treatment of hot water cup control board relay can not work
6.Temperature control device out of control or insensitive Solutions: inspection and repair the wires, replace the hot water cup, film relay and a temperature machine

Scaler can not work normally

1.Inspect the work power of scaler
2.Inspect the power of the relay (footplates) circles
3.Check relay pull-in and off circumstances and whether any voltage output
4.The scaler caput isn’t tight or it collapsed by long time using, in this situation, the user should use the equipped spanner to tighten the scaler caput.
5.Check power adjustment potentiometer weather too small, if it is too small, tuning clockwise is ok
6.If any screw is loose, should tighten it.
7.If the electromagnetism valve of scaler have been bad, must replace the electromagnetism valve
 

Curing light lamp is off

1.Use the multimeter measure the lamp to see whether it burn-our, if it burn-out, then replace one new.
2.Check the curing light lamp foot whether it is of oxidation, if it have been oxidated, should use the blade to cut the oxide.
3.Measure the power of curing light lamp, whether it is normal and the output voltage through mainboard whether it is up to the mustard.
4.Check the insurance pipe whether it have been bad

During the handpiece operating, the hydrosphere meet some problem

1.Pipelines problem
2.Check the air filter pressure relief valve whether the air pressure meter show up to six kilograms
3.Check the water filter whether block by wastes, if the wastes block the filter, then clean it up.
4.Check the side-box at the bottom of the water whether switch the location with anti
5.Check the footplate switch whether it connect bad

Hot water cup can not heat up or the water temperature is too high

1.The power or the wires are abnormal
2.Public lines of temperature line for cup hot water are in wrong connection
3.Temperature-controlled machine or the hot rods of hot water cup have been bad
4.Controlled mask have been bad
5.The treatment of hot water cup control board relay can not work
6.Temperature control device out of control or insensitive Solutions: inspection and repair the wires. Replace the hot water cup, film, relay and a temperature machine

2.Inspect the power of the relay (footplates) circles
3.Check relay pull-in and off circumstances and whether any voltage output
4.The scaler caput isn’t tight or it collapsed by long time using , in the situation, the user should use the equipped spanner to tighten the scaler caput
5.Check power adjustment potentiometer weather too small, if it is too small, tuning clockwise is ok.
6.If any screw is loose, should tighten it
7.If the electromagnetism valve of scaler have been bad, must replace the electromagnetism valve

Curing light lamp is off

1.Use the multimeter measure the lamp to see whether it burn-out, if it burn-out, replace one new.
2.Check the curing light lamp foot whether it is of oxidation, if it have been oxidated, should use the blade to cut the oxide.
3.Measure the power of curing light lamp, whether it is normal and the output voltage through mainboard whether it is up to the mustard.
4.Check the insurance pipe whether it have been bad

During the handpiece operating, the hydrosphere meet some problem

1.Pipelines problem
2.Check the air filter pressure relief valve whether the air pressure meter show up to six kilograms
3.Check the water filter whether block by wastes, if the wastes block the filter, then clean it up
4.Check the side-box at the bottom of the water whether switch the location with anti
5.Check the footplate switch whether it connect bad

Pipeline question

1.For a long time using friction or squeeze, will lead the hydrosphere tube or handpiece tube to burst off, sclerose ( note: the handpiece cleaner will lead the handpice outer tube to sclerose)
2.Wastes block the pipeline, so it need to clear in aregular period.
3.No water for gargling, you should check the water
4.Leaking pipes leakage, should inspect the leaking pipeline leakage and replace them
5.Pipeline interface is not tight or is a litter loose, the should tighten it again

Electromagnetism valve problem

1.As a result of time spent too long, then lead to aging solenoid valve and water leakage and gas leakage
2.The tap have been anti-access
3.Electromagnetic valve interface is not strong which lead to water leakage and gas leakage
4.There are some quality problem for the electromagnetic valve
5.The poor water block the electromagnetic valve

Circuit board problem

1.Short circuit ● wrong connection with the two tie-in
● the dregs which make by the wet position of circuit board discharge for long time will cause short circuit.
● the screw of connection board being loose will lead to short circuit
2.The connection of the two tie-in is loose or oxidation will lead to the circuit out of normal working.

Water bottle question

1.The bad decompression valve for two kilo will cause the high air press int the bottle which will make the water bottle burst.
2.The water which add to the bottle is not the distilled water
3.Water tube have blocked
4.Some quality problem will cause the water bottle bad function to afford the press. Changing problem between the water bottle and the tap water
5.When you are ready to use the water from the water bottle, you should check the water source conversion switch whether open and the master air switch too.
