SAFETY PRECAUTIONS WA R N I N G 11. Do not place articles weighing 3 kg or more on the instrument table.

Do not place articles weighing 3 kg or more on the instrument table. Failure to heed this warning may result in breakage, malfunction of the table, or an accident.

12. Do not apply excessive force to the arms. Do not mount or apply unnecessary force to the unit arms or the armrests of the patient chair. Failure to heed this warning may cause an accident or the unit to tip over.

13. Do not sit on other than seat

When the backrest is at the forward position. do not sit on or place an undue load on the headrest or legreat of dental chair. This could cause the unit to topple or could damage the unit.

14. Do not place a load on the top of the unit. Do not get on, sit on or place heavy objects on the top of the unit. Damage to the top of the unit may result in physical injury. 15. Immediately wipe off any water spills or leakage on the floor

Immediately wipe off any water spills or leakage on the floor. Decreased strength of the floor may lead to physical injury including fall, or property damage.

16. Take action for power fail

Shut down the main switch of Doctor`s table after power fail recovery due to avoid the unexpected movement.

CAUTION 1. The system must be operated or handled by a qualified dentist or by dental staff under the supervision of a dentist. Persons other than dentists or other dental professionals must not use the system.

2. Check safety before operating the product.

Before operating the system, be sure to check that all parts operate normally and safely, and that there are no obstacles in the area.

3. Pay attention to the patient and children.

Be careful to avoid accidents due to mischief or careless operations by the patient (children in particular). Keep an eye on the patient.

4. Stop operation of the system when feeling something is wrong.

During inspections, pay attention to any looseness, wobbling, inclination, vibration, abnormal sounds, temperatures, or odors. If something is out of place, even slightly, immediately stop operating the system.

5. Do not strongly hit or scrape the system.

Do not strongly hit or scrape the system. Failure to heed this caution may result in breakage of the cover or malfunction of the system.

6. Be sure to operate the switches by hand.

Except for the footswitch, be sure to operate the switches by hand. Operation of switches by means other than hands may result in breakage or system malfunction.

7. Take caution when using water other than city water.

The system is designed for use with city water. Use of water other than city water (such as water-line sterilization system) may result in system failure.

8. Request for flushout of water staying in the unit

In order to maintain the quality of the treatment water to stably supply water to the handpieces, be sure to thoroughly flush out any remaining water in the unit before starting treatment. Refer to the pages for the flushing out procedures.

SAFETY PRECAUTIONS CAUTION 24. Precautions for use of handpieces

Handpieces may have poor spraying performance or generate heat due to the lack of cooling water/cooling air. In the case of the development of heat or an odor of something burning, immediately discontinue use and contact the dealer or our company because burns may occur or dental pulp may be adversely affected.

25. Do not use the water cleaning filter in a setting where freezing is expected

Do not use the water cleaning filter in a setting where freezing is expected. Damage to parts may lead to water leakage.

26. Observe the following when cleaning the Spittoon bowl: Never use sandpaper, wire wool, or detergents containing abrasive compounds to clean the Spittoon bowl. Do not use overly acidic or alkaline pipe cleaning agents, as they may corrode metals. 27. Caution when cleaning the plastic covers:

When cleaning the plastic covers, use only the desinfectant (Durr FD333) recommended by this company or a diluted neutral detergent, or the plastic cover may crack. After cleaning, make sure to wipe off all residue with a dry and soft cloth.

28. Air pressure of the clean water system (optional) must be less than 0.2Mpa.

The air pressure to the clean water system must be regulated to less than 0.2Mpa. Excessive pressure may rupture the clean water system.

29. Do not use water for the clean water system (optional) other than purified water, distilled water or pure water. For the clean water system use only purified water, distilled water or pure water. Do not use such as mouth wash or electrolytic solution which may cause clogging in tubings or adverse effect on inner valves and instruments.

30. Close the water main valve at the end of the day.

Make sure to close the water main valve at the end of the day to prevent a water leakage.

31. Read the documents accompanying the various pieces of equipment Before use, be sure to carefully read the package inserts and Instruction Manuals accompanying the various pieces of equipment (including optional articles) to ensure proper use.

NOTICE 1. Troubleshooting and contact information

In the case of any problems, discontinue use, turn off the main switch and contact the dealer or our company.

2. Operational check of the air compressor:

If air is not supplied to the product, the system will not function even if the main switch is turned on. Before operating the product, turn on the power to the air compressor.

3. The air turbine must be of the type with a water check valve. The air turbine must have a water check valve. If the turbine is not the correct type, contact your dealer or our company.

4. Handling of the system during power failure:

If the system stops during operation due to a power failure, place the handpiece in the holder, and turn off the main switch.

5. Function of the flow adjustment valve/knob

The function of the flow adjustment valve/knob is to regulate, not to stop, air/water flow. Do not overly tighten the valve/knob or the knob may break.
