WS-75, WS-75 L G The medical device has a considerably higher level of efficiency than normal contra-angle handpieces and has been designed to fit W&H drive units. When using the medical device on other surgical units, the user assumes sole responsibility. The manufacturer accepts no liability. Any concessions can be granted directly by the manufacturer of the drive units.

11

Risks due to electromagnetic fields WS-56 L G, WS-75 L G, WS-91 L G, WS-92 L G This medical device is suitable for use on patients with cardiac pacemakers, if a safety distance between the medical device and the cardiac pacemaker of at least 15 cm (5,9 inch) is maintained. The functionality of other active implantable medical devices (AIMD) (e.g. ICD) can be affected by electric, magnetic and electromagnetic fields. > Find out if the patient has other active implantable medical devices (AIMD) before using the medical device and inform about the risks. > Do not place the applied part on the patient’s body.

12

Hygiene and maintenance prior to initial use > The medical device is sealed in PE film and not sterilized when delivered. > The PE film and the packaging are non-sterilizable. > Clean, disinfect and lubricate the medical device. > Sterilize the medical device, the nozzle cleaner, the Y-manifold, the spray clips and the coolant tube for internal bur cooling system.

4. Start-up

Assembly/Removal WS-75 L G, WS-75 Spray clip Coolant tube for internal bur cooling system



 Attach the spray clip.  Insert the coolant tube for internal bur cooling system.



Check the secure hold of the spray clip and replace it if necessary or  Remove the coolant tube for internal bur cooling system.  Remove the spray clip.

16

Medical device Do not assemble or remove the medical device during operation!

 Push the medical device onto the motor and turn until it engages audibly.

When using a locking pin between motor and medical device: See Instructions for use of the control unit.

 Verify full engagement. or

 Remove the medical device.

17

WS-75 L G, WS-75 Y-manifold Only when using the coolant tube for internal bur cooling system.

 Insert the coolant hose of the Y-manifold onto the

coolant tube of the spray clip and onto the coolant tube for internal bur cooling system.  Insert the Y-manifold into the irrigation tubing. or

 Remove the Y-manifold.

18

Rotary instruments > Use only rotary instruments which are in perfect condition and pay attention to the direction of rotation of the rotary instrument. Follow the operating instructions of the manufacturer. > Insert the rotary instrument only when the medical device is stationary. > Never touch the rotary instrument while it is still rotating. > Do not activate the push-button of the medical device during operation. This leads to detachment of the rotary instrument, damage to the chucking system and/or heating up of the medical device. Risk of burning! When having a torque higher than 30 Ncm on the rotary instrument you have to use hardened shafts (>50 HRC, >520 HV) (risk of deformation).

19

To change the rotary instrument WS-56 L G, WS-56 > Instrument shaft diameter 2.35 mm

 Insert the rotary instrument until the limit stop.  Turn the rotary instrument until it engages.  Verify full engagement. or

 Activate the push-button and remove the rotary instrument.
