AquaCare: Maintenance
Handpiece Maintenance
Blockages
If the abrasive powder ceases to flow from the nozzle while cutting is in progress, the
nozzle may have become blocked with abrasive particles. Turn off and depressurise the
machine. Now remove the handpiece and clear the blockage by inserting a length of
0.35mm wire (supplied) through the nozzle from the tip.
Inspection
Regularly inspect the cutting nozzle and handpiece for excessive wear or damage.
Do not use a handpiece if the hole in the tip of the nozzle is worn to the outer edge or
if the abrasive perforates the swan neck tube.
The life expectancy in normal use is approx 6 months. Using the AquaCare at its higher
power and media setting will lead to higher wear rates on the handpiece.
The handpiece is a consumable, see page 40 for part reference.
Twin Tube Assembly Maintenance
Cleaning
The Twin Tube Assembly must not be autoclaved. Wash the Twin Tube Assembly in
mild soapy water and rinse thoroughly. Allow to dry completely before use. Always
purge the tubes with Powder and Fluid thoroughly before use.
Inspection
Ensure the Twin Tubes are in good condition and fit together correctly with the
Handpiece. Test the Check Valve is functioning. The valve prevents fluid being forced
back down the tube during use.
Check 1 - With the twin tube filled with fluid, disconnect the tube at the Fluid Out
connection, (page 10, item 13). Hold the handpiece up vertically and check that the
fluid in the tube does not drip from the disconnected end. Reconnect the tube.
Check 2 – With the machine in the ‘ready to use’ condition, press the ‘Wash’ control on
the foot pedal and gently press the plastic tip on the end of the nozzle down onto a flat
surface (e.g. a glass slide). The fluid should be prevented from blowing back down the
fluid line past the handpiece. The joint between the plastic tip and feedline may also
disconnect.
Replace the whole check valve assembly if any faults are found. The twin tube
assembly should be replaced annually.
