Dental Handpiece Turbine Repair / Replacement User Guide
IMPORTANT – READ BEFORE PROCEEDING
Before replacing the dental rotor, carefully examine handpiece head for dents. If there is any evidence of dents in the head, return the entire handpiece to your dental engineer or dental repair shop for repairs. Do not install new dental rotor into the handpiece in case there are external damages. The installation of the new dental turbine in a damaged head will result in permanent damage to the dental High-speed handpiece. Alternatively, you may purchase a handpiece dental turbine cavity reamer /head expander from www.dental-rotors.com to remove the dents on your own but as any repairs, you must have special skills.
1. Using specialized dental back cap key/ push button Wrench, unscrew the dental back cap from handpiece head and remove the worn dental turbine by pushing out from the front. Only use the appropriate tool to remove the end cap. Use of a pliers or inappropriate tool will cause damage to your dental handpiece.
2. WARNING: Interior of the head must be inspected for foreign material and debris—remove if present. Compare worn dental rotor to a new dental turbine to identify any components that may still be present in your handpiece. Use a scaler or explorer to remove all old dental turbine components including any shims, o-rings, washers or bearing retainers. Once all old dental turbine components have been removed, use a cotton swab and dental handpiece lubricant to clean dental handpiece head. Using air from the air/water syringe, blow out handpiece head to remove any cotton fibers.
INSTALLATION of Dental Turbine:
1. The dental turbine also a lot of dentist use term as the dental rotor is provided with two o-rings which must be replaced by the existing turbine o-rings because are burned in time and autoclavable and it loses their properties and functionality in time. One o-ring fits into a groove in the front (bur end) of the handpiece, the other o-ring must be fitted into a groove in the dental back cap end. You may need to use a scaler or explorer to remove the old o-rings from your dental high-speed handpiece and end cap. A burnisher or similar blunt instrument may be helpful when installing the new o-rings to make certain they are fully seated.
Special attention must be paid to the o-rings to ensure that the old o-rings are completely removed and the new ones are not misaligned, twisted, or otherwise out of place.
2. Generously lubricate the interior of the dental handpiece, paying particular attention to the o-rings. Holding dental handpiece face down, insert dental turbine fully into dental handpiece head. The dental rotor bearings each have a small lip which will rest against the o-rings. Using the appropriate tool, screw end cap down until flush against handpiece head. CAUTION: End cap should be tightened securely with a special wrench to ensure the safe positioning of the dental high-speed turbine. If you are unable to fully seat the end cap, remove and check the end cap for debris/old turbine components. If the difficulty persists, send the replacement dental rotor and handpiece to dental repair shop for installation.
