e scheduled maintenance information included in this Preventive Maintenance manual is provided as a guide to assist the customer in getting
the greatest ownership value from their Midas Rex® Legend EHS® System, while helping to maximize its performance, safety, and reliability. is
scheduled maintenance program is in addition to the required routine cleaning a er each use. ( e 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.)
is manual is divided into two sections.
Section 1 contains the preventive maintenance/service schedule. How much scheduled maintenance a Midas Rex Legend EHS System requires
depends upon how o en it is used and the conditions to which it is subjected, such as cleaning and sterilization. e demands on these systems
can vary greatly from facility to facility. Twelve maintenance intervals have been de ned. e time interval is determined by tool usage per year
per motor and has been identi ed as levels A, B, C, or D as determined from the following chart.
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.
WARNING: Failure to follow recommended service and preventive maintenance schedules for attachments may prevent tool from being
secured properly.
Identifying and following the scheduled maintenance intervals for the Midas Rex Legend EHS System will assist in reducing the potential for
unanticipated down time as a result of wear.

e preventive maintenance schedule found in Section 1 details the speci c 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 Medtronic Powered Surgical Solutions (MPSS) for service.
e maintenance checkpoints have been designed for a facility’s Biomedical Department or equivalent to perform. e following symbols
are used throughout this manual to indicate whether the maintenance step may be performed by the customer or must be returned to MPSS:

Instructions for Completing Preventive Maintenance Steps
1. Visually inspect the power cord to verify that it does not have any damage to the insulation or to the blade of the connector and that there
is no debris evident. Replace if damage is apparent.
2. Connect the foot control and motor to the console with their respective cables. Plug the power cord into the console then turn the console
on. Verify that the console beeps while powering up, that the display comes up and is readable and clean. e display should read:
EHS FORWARD >>
70000 RPM
3. If the display shows this error, then the foot control is not properly connected or the foot
control or cable connectors may be dirty or the foot control or cable may need servicing.
4. If the console is working as in step 2, push the Up and Down buttons to Verify that the speed up and down buttons function from 10,000
to 75,000 in 1,000 rpm increments for EHS. For EHS Stylus from 3,000 to 9,500 the increments are 500 rpm and from 10,000 to 75,000 in
1,000 rpm increments.
5. Connect an attachment to the motor and verify a tactile and audible click when the attachment is locked on the motor.
6. Run the motor and verify that the pedal smoothly controls the motor speed.
7. If the display shows any errors, then the motor is not properly connected or the motor cable may need servicing or the connectors of the
motor or motor cable are dirty, or the motor or console may need servicing.
8. Press the Reverse button on the foot control several times and verify that the console display toggles between << REVERSE and
FORWARD >>. Leave the console in the << REVERSE mode. Press the foot pedal to start the motor in reverse and listen for 3 beeps when
the motor starts in reverse.

9. Run motor for 3 minutes at 70,000 rpm for EHS or 5 minutes at 60,000 rpm for EHS Stylus. Verify that the motor case, attachment base
and tip do not become uncomfortably hot to the touch.
10. Verify that when the foot pedal is released the motor stops and does not continue to run. If the motor continues to run when the foot
pedal is released, DO NOT use and return system to MPSS for service.
Attachments: Straight, Footed, Perforator, Jacobs Chuck, and Telescoping
Telescoping tubes are multi-use disposable and do not receive scheduled maintenance.
1. Visually inspect the etching and color ring to ensure it remains legible and the color is distinguishable.
2. Visually inspect the attachment tube and base for any signs of debris or damage.
3. Visually and physically inspect (pulling and twisting by hand) the attachment for any loose or loosening components. If any components
loose, DO NOT use and return the attachment to MPSS for service.
4. (Straight/Footed) Visually inspect the attachment tip for any signs of wear. e tip should remain round with no evidence of deformation.
5. (Footed) Visually inspect the foot. e foot and/or leg of the attachment should not be bent, or damaged.
6. (Perforator and Jacobs Chuck) Visually inspect the perforator collet for any signs of wear or deformation.
7. Heat Check
• For telescoping attachment, insert an appropriate telescoping tube into the base.
• Attach and lock the attachment onto the motor. Check to ensure that there is a tactile and an audible click when the attachment is
locked on the motor.
• Connect the motor to a console with foot control attached.
• Turn console on.
• Run the motor for 3 minutes.
• Feel the motor case, the attachment base, and the attachment tip (except Telescoping) to ensure they are not uncomfortably hot to
the touch.
8. Repeat steps 1-7 for each straight/footed/telescoping/perforator/Jacobs Chuck drive attachment in this system.

Attachments: Angled, Contra and Metal Cutting
1. Visually inspect the etching and color ring to ensure it remains legible and the color is distinguishable.
2. Visually inspect the attachment tube and base for any signs of debris or damage.
3. Visually and physically inspect (pulling and twisting by hand) the attachment for any loose or loosening components. If any components
are loose, DO NOT use and return the attachment to MPSS for service.
4. Visually inspect the attachment tip for any signs of wear. e tip should remain round with no evidence of deformation.
5. Heat Check Angled and Metal Cutting Attachment
• Attach and lock the attachment onto the motor. Check to ensure that there is a tactile and an audible click when the attachment is locked
the motor.
• Connect the motor to a console with foot control attached.
• Turn console on.
• Run the motor for 3 minutes.
• Feel the motor case, the attachment base, the knuckle (angled area for angled attachment only), and the attachment tip to ensure they
uncomfortably hot to the touch.
6. (Contra) Visually inspect the head to tube joint for the contra-angled attachment for stability, i.e., there is no loosening of this joint.
7. Heat Check Contra-Angled Attachment
• Attach and lock the contra-angled attachment onto the motor. Check to ensure that there is a tactile and an audible click when the
attachment is locked on the motor.
• Connect the motor to a console with foot control attached.
• Turn console on.
• Run the motor for 1 minute.
• Set speed to 62,000 rpm using the speed down button for EHS or the speed up button for EHS Stylus.
• Feel the motor case, the attachment base, the knuckle (contra-angled area), and the attachment tip to ensure they are not uncomfortably
to the touch.
8. Repeat steps 1-7 for each angled/contra-angled/metal cutting attachment that is part of this system.
