Troubleshooting - Water Supply Circuit
If you experience any one of the following failures, try step-by-step troubleshooting described below.
- Insufficient water supply
- Irregular water supply
- No mist spray
- No water at all
Fixing blockage in water spray nozzle of cartridge
Remove head cap and take out cartridge.
Detaching of cartridge
Take out cleaning pin at the rear end of the brush, and insert it straight into the water spray nozzle.
* The water hole may be damaged if the pin is not inserted straight or forced into the hole. The damage may cause water not being sprayed at right angles. Use attached NSK Nozzle Cleaning Pin. Using non-NSK cleaning pin may cause improper direction of water spray.
Make sure the pin reached the upper chase (chip air chase) and then clean up debris there by using cleaning brush.
Cleaning of pouring water nozzle
Blow air from the bur side by using syringe.
When placing the cartridge back to the head, be sure that O-ring is set properly in place.
* In case clogging is found in turbine or coupling joint, contact your NSK distributor for repair.
If you feel water supply is insufficient upon installation of NSK air turbine NSK air turbine is designed to make spray water by mixing water and chip air internally. When chip air pressure is set substantially higher than water pressure, water supply may be diminished due to the pressure difference. If this is the case, adjust chip air pressure. NSK recommends using Multi-gauge to make adjustment correctly.
