PackagingFor sterilization, place devices in instrument tray. Devices may be unwrapped or wrapped with up to two layers of 1-ply polypropylene wrap.
SterilizationNote: The temperatures and times for sterilization are the minimum required.
Thoroughly dry attachments. An air gun may be used to blow moisture out from rear to front of attachment.
Note: Medtronic no longer recommends using the Legend attachment cleaning nozzle (PA120), as this may cause some attachments to overheat.
Using an aerosol spray lubricant (such as Pana Spray), perform the following steps to lubricate attachments:
Holding the can approximately 10-15 cm (3-6 inches) away from the attachment, spray all components that move, rotate, or slide with
three quick squirts.
Articulate movable components to ensure proper lubrication.
Remove excess lubricant with a clean cloth.
For sterilizing the attachment and tubes, either the PA400 instrument case or the PA600 instrument case may be used.
Inspect devices for any damage before and after each use. If damage is observed, do not use the device until it is repaired.
Verify functionality prior to re-use.

Preventative maintenance
Legend pneumatic high speed preventive maintenance/service program
The Midas Rex Legend Pneumatic High Speed System preventive maintenance/service program has been developed to assist you in getting the greatest ownership
value from your Midas Rex Legend Pneumatic High Speed System, while helping to maximize its performance, safety and reliability. The scheduled preventive
maintenance/service program is in addition to the required routine cleaning after each use. Please refer to the following preventive maintenance information for the
specic steps necessary to maintain Midas Rex Legend Pneumatic High Speed System.
Dening maintenance level
The following scheduled maintenance information is provided as a guide to assist the customer in getting the greatest ownership value from their Midas Rex Legend
Pneumatic System, while helping to maximize its performance, safety and reliability. This scheduled maintenance program is in addition to the required routine
cleaning after each use. (The scheduled maintenance program is one of three programs, Limited Warranty, and Extended Maintenance Agreement are the other two,
intended to help you keep your system in good condition.)
The maintenance information is divided into two sections.
Section 1 contains the preventive maintenance/service schedule. How much scheduled maintenance a Midas Rex Legend Pneumatic System requires depends upon
how often it is used and the conditions to which it is subjected, such as cleaning and sterilization. The demands on pneumatic systems can vary greatly from facility to
facility. Twelve maintenance intervals have been dened. The time interval is determined by tool usage per year per system and has been identied as levels A, B, C, or D
in accordance in Table 9.
Table 9: Maintenance level
Maintenance level
A150–20012–16*3 months
B100–1498–114 months
C50–994–75 months
D<50<46 months
*A motor with usage rates greater than 16 uses per month should be returned for factory maintenance at a 6-month interval.
Note: Failure to follow recommended service and preventive maintenance schedules for attachments may prevent tool from being secured properly.
Identifying and following the scheduled maintenance level for a Midas Rex Legend Pneumatic System will assist in reducing the potential for unanticipated down
time as a result of wear.
The preventive maintenance schedule found in Section 1 details the specic checkpoints that are recommended and its associated interval. It also provides a
convenient place to document your system’s maintenance history. If any of these checkpoints indicate wear or damage, DO NOT USE. Return the respective product
to MPSS for service.
The maintenance checkpoints have been designed for a facility’s Biomedical Department or equivalent to perform.
Section 2 contains the detailed instructions for servicing the Midas Rex Legend Pneumatic System in accordance with the Twelve Maintenance Intervals.
