AINTENANCE TIPS
To ensure that the safety, reliability and performance of the unit are not adversely affected, enhancements,
readjustments, alterations or repairs are not permitted aside from those performed by Promed authorized
persons.
A. Keep the inner parts of the handpiece (Collet chuck/quick lock chuck) as free as possible from dust and
grinding residue.
B. Remove dirt from the outer surface of the handpiece with a cloth moistened with alcohol. Prevent moisture
from entering the unit.
C. Only use grinding heads with a dental standard size (ø 2.332 – 2.350 mm (0.091 - 0.093 inches), shaft
length 28 - 36 mm) and avoid using rusted or damaged grinding heads. Their false usage may lead to
excessive wear and tear in the ball bearings. Adhere to the safe speed and the safety measures stipulated
by the manufacturer.
