Initial startup Replace the fuse (if necessary) The control unit is factory set to 230 V and equipped with two 2 A fuses . One of these two is intended to be a spare . Two 4 A fuses are also included . Caution! Only use the following fuses: •...
Connecting a motor cable Caution! Always insert the cable carefully into the socket on the control unit and make sure that the con- tacts and threads are not damaged . • Connection A: BLDC - brushless DC motor • Connection B: BLDC - brushless DC motor •...
Connecting a handpiece Caution! Carefully push the motor and the handpiece together and make sure that the contacts, the motor shaft, the handpiece coupling and the threads are not damaged . Always use the supplied tool . If there is resistance before the thread is completely screwed in, first turn the handpiece’s collet chuck manually until the coupling engages .

Installing or changing a tool Warning! To avoid injuries caused by the tool turning unintentionally, only connect or change tools when the control unit is switched off . Warning! To avoid injuries caused by tools coming loose, always insert the tools into the collet chuck as far as they will go and also adjust the collet chuck on the JEHR 500, JIH 300 and JIR 310 handpieces .
Operation Switching the unit on and off Fig . 19 Choosing the direction of rotation Anti-clockwise (LEFT) rotation can only be selected if the handpiece is approved for two direc- tions of rotation . Option A: 18 000 rpm LEFT LEFT FOOT LEFT Fig .

Using foot mode A foot pedal can be used to control the speed of the tool using your foot during operation . Vari- able speeds between 0 and the set speed can be selected . Switching foot mode on XX rpm Fig .
Using the memory function (MEM) The memory function makes it possible to store one speed, one direction of rotation (anticlock- wise or clockwise) and the activated foot operation for each of the three connections (A, B or C) so that the settings are retained even if the control unit is switched off and then on again . If the memory function is activated (MEM button illuminated), the settings on the control unit cannot be changed .
Setting a timer As soon as a motor runs without a load, a timer will count down and switch the motor off as soon as the set time has elapsed . The factory setting is one minute . Action Shown in the display = ESC = XXXXXXXX = = ESC = MAIN MENU = -----------------------------------...
