Point of Use (before reprocessing)
Remove excess soil with a disposable cloth or other suitable wipe.
Containment and Transportation
It is important that this equipment is reprocessed immediately after use. In order to minimise
contamination risks, the handling, collection and transportation of soiled equipment should be
strictly controlled.
Cleaning and Disinfection
Manual Cleaning
• Remove all attachments and accessories and wash them separately.
• Dispose of single-use accessories in accordance with local guidelines.
Manual cleaning should only be carried out where an automatic washer-disinfector is not
available, or in order to remove large contaminant deposits. Manual cleaning should be conducted
in a dedicated area, by trained personnel who are wearing protective clothing, for example:
gloves, a waterproof apron, and goggles or a visor.
NOTE: the use of dedicated sinks with temperature controlled water, ideally deionised or distilled,
is recommended
NOTE: cannulations, blind holes, recesses, and other surfaces which are hard to reach, require
particular attention during reprocessing
1. Wash off excess soil with running water (maximum 35°C).
NOTE: avoid fluid ingress
2. Prepare a solution of detergent according to the detergent manufacturer’s instructions.
3. Remove all visible traces of contaminant, using suitable nylon brushes to scrub the
equipment thoroughly.
i) Manually open and close chucks and blade clamps.
ii) Ensure any trapped contaminants are removed by flushing through cannulations
and other surfaces which are hard to reach.
4. Rinse off all traces of the detergent with deionised or distilled running water (45 - 65°C).
5. Shake off any excess water and dry the surfaces with a lint-free cloth.
6. Visually inspect each item. Verify that all contaminants have been removed in
accordance with local reprocessing guidelines.

6
Automatic Cleaning
• Remove large contaminant deposits by manual cleaning.
• Remove all attachments and accessories and wash them separately.
• Dispose of single-use accessories in accordance with local guidelines.
An automatic washer-disinfector, capable of meeting the relevant national and international
cleaning and disinfection standards (such as, ISO 15883 or HTM 2030), should be used.
CAUTION: the drying cycle should not be used with batteries. The drying cycle will adversely affect
the performance and life of the battery.
NOTE: cannulations, blind holes, recesses, and other surfaces which are hard to reach, require
particular attention during reprocessing
1. Place the handpieces, attachments and accessories into an insert tray and/or a wire
basket.
i) Set chucks and blade clamps to a middle position.
ii) Ensure that sterile batteries are inverted (that is, contacts facing down).
iii) Ensure that aseptic battery housings are empty and open, with the open side facing
down.
iv)Fit washing spacers and end caps as required.
v) Ensure that all items are separated.
NOTE: the placement of items in automatic washer-disinfector baskets can be a critical
factorin achieving effectivecleaning.The basket type andthepositionof the items within
the basket should be managed by suitably trained personnel and be in accordance with
the washer-disinfector instructions.
2. Follow the washer-disinfector manufacturer’s loading instructions and select the
appropriate cycle. The cycle should include the following:
Cycle Stage

3. Remove the disinfected equipment from the washer-disinfector and place the equipment
in a clean area.
4. Remove any washing spacers and end caps, if fitted.
5. Visually inspect each item. Verify that all contaminants have been removed in
accordance with local reprocessing guidelines.
Disinfection
Thermal disinfection is recommended and included in the automatic cleaning process.
Where the use of an automatic washer-disinfector is not possible, the equipment should be wiped
with a suitable disinfectant.
Maintenance
Lubricate collets and chucks using a suitable surgical instrument oil.
Inspection and Function Testing
WARNING: inspect all equipment before use and do not use suspect, damaged or worn equipment

Configuring a Handpiece
Selecting the Mode
WARNING: ensure the handpiece is set to SAFE mode before attempting to change the handpiece
configuration, and before fitting or removing attachments and accessories
Slide the mode selector to choose the required mode.
WARNING: tapping mode should be used with care. To minimise the risk of damage, tapping and
screwing in delicate materials should be performed with hand tools instead.
Controlling the Speed
The speed of the handpiece is controlled by progressively pressing the trigger.
Oscillating and Tapping
Oscillating and tapping modes are utilised by pressing both triggers together. The speed of the
handpiece is determined by the trigger which is pressed the least.
NOTE: release both triggers to return to using independent trigger control
CAUTION: ensure the triggers are only pressed independently when using a saw attachment
