PH3 On/Off motor switch
All Power Hand 3 rotary motors feature a convenient on/off motor switch
(Fig. 2) for easy access to start/stop the motors. The Power Hand 3
On/Off motor switch will only function when connected to the Power
Hand 3 controller. When connected to a Power Hand 2X controller
(via the PH3 adaptor plug), the On/Off motor switch will have no affect.
Simply press the On/Off motor switch to start or stop the rotary handpiece.
Be careful not to push the On/Off motor switch when changing collet chuck
or any tools.

Operating Procedure with Power Hand 3 Controller
With your rotary handpiece fitted with a selected tool, connect the Gesswein
Power Hand 3 Controller to an electrical supply and the handpiece to the
A motor or B motor output socket.
Put the Controller Main Switch to the “ON” position, which lights up the LED
lights of controller. Then select the A motor or B motor button depending
on which socket the handpiece is plugged in to. Check to make sure the
desired rotational direction is selected on the Fwd./Rev. button. Then press
the START/STOP button to supply power to your handpiece. RPM speed is
adjusted by the round dial in the center. It is always best to start at minimum
RPM and then increase to the desired RPM speed.
A Load Indicator light is located on the front panel of the PH3 Controller with
8 steps of LED lights from green to yellow to red. The display lights up as
force is being applied to the handpiece. For best results and long life, stay
within the green.
