ACTUATOR BODY

Assembly Spray all moving components with a spot lubricant. Enztec recommends Rudolf® Medizintechnik Oil Spray RU8880-00. Remove excess oil with a lint-free cloth. Do not use oil with a silicone base for surgical instrument maintenance. Silicone components can harden during subsequent processing (sterilisation) and cause the instrument to become stiff. Plastic surfaces should not be treated with oil. Since effective ultrasonic cleaning removes all lubrication, re-lubrication is important. ACTUATOR INSERTION: – Ensure the Lever is closed. – Apply lubricant to the Actuator and corresponding slot in the Body. – Slide the Actuator tip into the Body. – Line up step of Actuator with step of Body while lowering the Actuator into the Body.
