4. Operation
• If you press the FORWARD button briefly, the
motor handpiece starts. If you re-press the
FORWARD button, it stops.
• If you hold down the FORWARD button for more
than one second, the motor handpiece starts
and runs while the button is pressed. If you
release the button, it stops.
• If you press the REVERSE button, the motor handpiece operates in the reverse
direction until you release the button.
NOTE: If the plus (+) key or minus (-) buttons are continuously held down, they cycle through the
selection quickly.
5. Auto Reverse Function
To choose the auto reverse function, use the SELECT button to highlight the auto
reverse field and use the minus (–) button to turn on and plus (+) button to turn off.
NOTE: The last position used for auto reverse (on or off) is what will be the default until user
manually changes it.
Auto Reverse On
The motor handpiece stops and does reverse when the load exceeds the preset
Torque Limit Value. The Torque Limit box will show "S.t". When the load is removed,
the motor handpiece stops.
If you want the file to rotate forward again, press the FORWARD button.
