Warning Failure to properly secure Legend Lubricant/Diffuser may cause injury to operator and/or operating room staff.
Note The lubrication rate is pre-set by the factory and, therefore, should not be altered. Cartridges should not be left under pressure for more than 4 hours. If this occurs, an audible air leak may be heard from the diffuser housing. If the cartridge has been pressurized for longer than 4 hours, it should be replaced.
3. Insert Lubricant/Diffuser into lubricant/diffuser housing located at base of motor hose.
Caution 3
• DO NOT use a Legend Motor without a lubricant/diffuser installed in the motor’s lubricant/diffuser housing. • DO NOT use a Legend Lubricant/Diffuser if it appears to be damaged or if inner foil seal is punctured. • DO NOT exceed 1 hour drill time per surgery for a Legend Lubricant/Diffuser. • DO NOT attempt to remove Legend Lubricant/Diffuser while the motor is in operation. • DO NOT re-use a used Legend Lubricant/Diffuser. Legend Lubricant/Diffuser is a single use, disposable product. • DO NOT refill a used Legend Lubricant/Diffuser. • DO NOT steam or EO sterilize the Legend Lubricant/ Diffuser. The lubricant/diffuser will melt into the lubricant/diffuser housing with potential damage to the motor. The lubricant/ diffuser must be removed from the motor’s lubricant/ diffuser housing prior to sterilization.
Do not sterilize. Lubricant/diffuser will melt. 18
