Thank you for purchasing the PRESTO AQUA II.
Please read this instruction manual carefully, and file store it in a place where it can be easily accessed for future reference.
• PRESTO AQUA II is a handpiece used in dental laboratory work for cutting while preventing heat when performing fine
work on porcelain teeth, porcelain and ceramics. Do not use for other applications.
• When cutting, wear safety glasses, and use a grinding box and vacuum for safety.
• Do not modify or disassemble unnecessarily. Otherwise, performance and safety may be seriously affected. Please ask
your PRESTO AQUA II dealer whenever repairs are required.
• Do not drop the handpiece and unit. Make sure to put the unit on a horizontal and stable surface.
• Observe the permissible speeds the manufacturer or dealer designates for the bur. Otherwise, you may be injured by
scattering and breaking up of the bur.
• Do not use burs which are oscillating or bent or damaged and of which shank portions are worn. Otherwise, you may
be injured by scattering and breaking up of the bur.
• Do not turn the chuck release ring during rotation of the handpiece. Otherwise, the handpiece will be broken.
• Never supply lubricant to the handpiece. It uses a grease filled bearing and additional lubrication may cause failures.
• Pay careful attention to rattling, vibrations, sounds and temperature (heating), and inspect by rotating in advance
before starting use. Immediately ask your dealer for repair work if any irregularities are sensed.
• The proper air pressure is 0.25~0.35MPa. Pressure exceeding the value may lead to premature failure of the bearing
because of excessive increases in speeds.
• Extract water if water drips or contaminants are found on the filter of the unit.
• Always clean the shank of the bur you are going to mount. Contaminant deposits in the chuck may lead to oscillating
of the bur and breakage of the chuck.
• Install the cutting bur or test bur even when not in use.
• Operational control, maintenance and inspection is the responsibility of each user.
