NOTICE
– Hold the contra-angle handpiece tightly to prevent the contra-angle handpiece from slipping as a result of jet pressure during oiling.
– Oiling should be repeated until the contra-angle handpiece is clean and free from stains. If the blood remains on the contra-angle handpiece, blood clotting
may cause corrosion, resulting in phenomena such as low rotation speed or torque.
– Keep the lubricant spray can upright.
5. Storage and transport conditions

NOTICE
– If there are residual chemicals on the device, please do not autoclave the device. Otherwise it may lead to surface coating loss or damage to the internal
components.
– Keep the contra-angle handpiece in a place that is free from infl uence of dust, sulfi de or salt in the air.
– Do not touch the contra-angle handpiece immediately after sterilization under high temperature and high pressure, because the contra-angle handpiece is
very hot.
4. Maintenance
4.1 Lubrication
– Use Q-type nozzle to inject oil.
– Inject oil after removing the needle.
– Shake the lubricant spray can to mix lubricant well with the propellant.
– Insert the nozzle into the end of the contra-angle handpiece. Put a tissue on the head of the contra-angle handpie-
ce and keep the contra-angle handpiece spraying for 2-3 seconds. Check whether the tissue is clean. If it is clean,
the contra-angle handpiece can be autoclaved. If not, spray again until the tissue is clean. (Figure 15)
