4.1 Preparation for use

4.1.1 Pressure test

Place the testing pressure gauge between the coupler and the instrument to test the following pressures (see chapter 3.3 Technical specifications):
- Driving pressure
- Pressure of returning air
- Pressure of spray water
- Pressure of spray air
4.1.2 Testing the quantity of water
WARNING
Damage to pulpal or teeth
A too low quantity of spray water may result in an overheating of the head of the instrument and can lead to corresponding
injuries.
WARNING
→ Regulate the quantity of the spray water to a minimum of 50 cm
Check the quantity of water with a measuring cup. Check the spray water canals. In case of a too low water supply or a clogged nozzle, clean the
nozzle with the enclosed pin. See also chapter 7.1 Cleaning of the spray nozzle.
4.2 Operation
i
Prior to each working day, all systems with water supply have to be rinsed out for at least 2 minutes, before attaching an instrument.
After each treatment another rinsing process has to be performed for 20 to 30 seconds, especially concerning products that rewind/retract.
4.3 Attaching the instrument to the coupler
WARNING
Dysfunctions due to a decoupling of the instrument while operating
An instrument that is not correctly attached to the coupler may loosen while operating.
WARNING
→ Prior to each use check if the instrument and the coupler are correctly attached by slightly pulling at the instrument.
CAUTION
Damages due to an incorrect coupling
If the coupling process is not completely executed, the LED or the halogen light bulb of the coupling may be destroyed or its
lifetime may me reduced.
CAUTION
→ Please check if the instrument and the coupler are completely attached by slightly pulling at the instrument.
