Warnings & Safety Rules Failure to follow these instructions may result in serious injury to the operating staff. WARNING!: THIS EQUIPMENT MUST BE EARTHED! Danger!: Possible explosion hazard if used in the presence of flammable gases. Never permit untrained personnel to use this equipment. Do not attempt to use the equipment until all the instructions have been studied and understood. Always check that the voltage stated on the identification plate corresponds with the electrical supply. Always inspect all equipment and accessories before use. Do not use suspect or damaged equipment. Always use eye protection when cutting to prevent injury or infection from flying debris. Always disconnect the equipment from the electrical supply when cleaning, changing accessories or when not in use. Do not allow loose articles can be caught by the moving parts of the equipment. Do not immerse the control box or extractor in fluids. Do not drop the equipment. Only clean as directed in these instructions. De Soutter Medical strongly recommends the use of the CNS extractor in mortuary work. Product Description • NS3 Saw: The De Soutter Medical model NS3 is a low voltage saw designed for mortuary use. The saw is fully sealed to IP67, allowing it to be scrubbed and thoroughly cleaned after use. • Power Module: The dedicated power module provides 40V d.c. to the NS3 saw. It is available for either 110-120V a.c. or 220-240V a.c. supplies, and is mounted behind the CCS debris drum. • CNS Extractor: The CNS extractor provides a powerful suction at the cutting site, removing fumes and debris generated in the cutting process. These particles are ducted from the cutting site through the extraction hose and are contained in the disposable bag in the debris drum. • Extraction Hose Kit: The hose kit provides the hose and other accessories required for assembly of the CNS3 system. Mains Supply Lead If an unsuitable plug is fitted to the mains lead, remove and destroy this plug before disposal. The wires in the mains lead are coloured in accordance with the following code: Blue – Neutral Brown – Live Green/Yellow – Earth Connect the wires in the mains lead to a suitable plug as follows: Blue wire to the terminal marked either letter N or coloured blue or black. Brown wire to the terminal marked either letter L or coloured brown or red. Green/Yellow wire to the terminal marked either letter E or coloured green. It is recommended for increased electrical safety to use a Residual Current Device (RCD) with a suitable tripping current rating. Always check the RCD every time it is used.

System Assembly Saw & Power Module: • Connect the saw supply cable to the power supply socket and hand tighten the locking nut. Saw & Extractor Hose: • Attach the metal connector of the extraction hose assembly into the plastic elbow. Attach the other end of the elbow on to the vacuum hood of the saw. • Attach the hose inlet adapter to the extractor by screwing it on to the vacuum inlet spigot on the debris drum. • Secure the NS3 power cable to the hose with the clips provided. Extractor Handle: • Assemble the handle to the chassis and secure with the nuts and bolts provided. Saw: • Attach the blade of choice to the tool output shaft, secure the clamp screw and tighten with the hexagon key provided. • Always check the condition of the blade before use. The blade may be repositioned up to five times, therefore always presenting an unused section. • If the blade is excessively worn then dispose of it safely and appropriately. System Controls Power Module Controls: The power module is operated by the illuminated green switch. Select the desired saw speed by setting the control knob on the power module. Saw Controls: Operate the saw using the rear mounted On/Off switch (this switch remotely controls the extractor when set in Automatic mode). One press of the switch will turn the saw on; a second press will turn the saw off. Extractor Controls: Main On/Off Switch: Located at the front of the extractor powerhead handle. Automatic/ Manual Switch: • Automatic: The extractor will now operate when the tool is switched on, and purge itself for a few seconds after the tool is switched off. • Manual: The extractor is operated independently from the saw. HI/ LO Extractor Suction: Select the desired suction level with the HI/ LO suction control. LO suction is normally adequate for general cutting, and is much quieter.

Operation System Operation Set the controls for the extractor suction and saw speed to the desired settings. Switch the power module ON. This switch may be left ON permanently. Switch the extractor mains switch ON. In Automatic mode, the system will now be controlled from the On/Off switch on the saw. Do Not use the extractor to pick up fluids. The extractor is intended only to remove solid and aerosol debris from the cutting site. Cutting Technique Before use, the operator should handle the saw and determine the most convenient hold. Do not exert excessive working pressure - allow the blade to cut at it’s own rate. Excessive pressure will overload the motor, without increasing cutting efficiency, and will cause the overload light to illuminate. If excessive overload is used then the overload protection circuit will operate, and the tool will automatically switch off. If this occurs, wait a few minutes before restarting the saw. A new or repositioned blade will improve cutting efficiency, reduce vibration and temperature of the blade when cutting. Make the first cut both downwards and slightly sideways, at approximately 30°, in order to keep one side of the blade out of contact with the bone. This will allow the operator a greater sense of feel when the blade breaks through. After the first cut, all cuts should be made straight down. The cutter should be lifted slightly and moved sideways; the second cut can then be taken straight down, the operator feeling the break through quite easily. Cutting can then proceed in a series of down cuts, lifting and moving sideways progressively. Maintenance The system should be visually checked at each use for each of the following: • Condition of the electrical cables, for wear or abrasion. • The blade for wear and the blade retainer for tightness. • The system as a whole for damage. Never use any equipment you suspect to be damaged. Periodic Technical maintenance is not required. Check the bag and filters regularly for excessive contamination. Cleaning Use suitable disinfecting and cleaning materials as per local decontamination guide lines. It is extremely important the CNS3 is cleaned regularly and thoroughly. Always disconnect the CNS3 from the power supply before cleaning. Do Not allow the paper debris bag to become excessively contaminated. Cleaning Fluids: Select a good quality disinfectant suitable for cleaning mortuary instruments. Do Not use corrosive cleaning fluids or hypochlorite (bleach). Corrosive cleaning fluids will damage the CNS3.

Saw: • Detach the blade with the hexagon key. Remove the spindle guard or, if using the CNS extractor, the hood and elbow. Separate the hood and elbow before cleaning. • Carefully scrub all parts with a soft brush using a suitable cleaning or disinfection fluid. Remove all traces of debris. • Immerse parts in fluid for the recommended time. • Thoroughly rinse and dry before re-assembly. Power Module: • Wipe the power module with a cloth dampened in cleaning fluid. DO NOT IMMERSE. Extraction Hose: • Disconnect the extraction hose, and flush and/or immerse it in cleaning fluid. Extractor Cleaning • Clean the external surfaces of the extractor, inside the debris drum and wheeled chassis by wiping with a cloth moistened in non-corrosive cleaning/ disinfection fluid. DO NOT IMMERSE the powerhead. DO NOT HOSE down the extractor. Extractor Bag Replacement • Release the two powerhead latches, disconnect the plug in the powerhead socket and remove the powerhead. • Lift out the two permanent filters. Unzip the outer cloth bag and remove the paper debris bag by sliding the cardboard collar from the inlet spigot. Dispose of the bag and it’s contents safely and appropriately. • Paper bag replacement should be carried out in the reverse sequence. However, it is recommended to thoroughly clean the extractor first. Filter Cleaning • After prolonged use, or in the event of a split paper bag, wash and/ or soak the cloth bag and the permanent filters in cleaning/ disinfection liquid. • The Microfilter is not a user serviceable item and it must only be replaced by qualified technical personnel.
