5.1.4 Overhaul of the handpiece
Due to the effects of friction, the handpiece components are continuously exposed to
mechanical stress, which will cause minor wear.
The handpiece should be overhauled about every 1,000,000 pulses. This can be done
quickly and easily by the user of the device. All that is required is the overhaul kit,
which includes all required wear parts.
The overhaul kit can be ordered from your dealer.
Overhauling the handpiece
WARNING
Pulse triggering with an open handpiece results in
Danger of injury!
► Disconnect the handpiece from the control device before replacing the pulse trans-

CAUTION
If the shaft of the handpiece is damaged or uneven, then when removing or screwing
in the shaft without a suitable tool,
minor scratching injuries may occur.
► Be sure to use the open-end spanner provided to remove or screw in the shaft.
• Prepare a dry, clean and dust-free surface to place the handpiece on.
• Disconnect the handpiece from the control device.
• Unscrew the pulse transmitter screw cap from the handpiece.
• Unscrew the shaft from the handpiece and pull it out of the handpiece handle.
Use the supplied open-end spanner for this purpose.
