The manufacturer will not be liable for any changes made to the machine nor for any damage resulting from such changes. Even when the machine is used as prescribed it is still impossible to eliminate certain residual risk factors. [. . . ] Important: Oil, grease and cleaning agents are harmful to the environment and must be disposed of in an environmentally compatible way - not with household rubbish!3 Mains connection / switch The machine may only be operated with singlephase current 230 Volt / 50 Hz. The electric circuit of the house must be protected by no more than a 16A fuse. 3) The hinged chip guard (16) must be in the "down" position before the machine is switched on. If the green indicator light (a) illuminates, the machine can be switched on using the speed selector switch (6) and the desired rotational speed can be set. If the orange indicator light (b) also illuminates, the speed selector switch (6) must be put into the "0" position and the yellow light will go off again. The desired rotational speed of the machine can then be set and the machine will start up. 2 Switching off the machine Switch the machine off by pressing the red "O" button or the "EMERGENCY OFF" button (c) and then unplug the power plug. Important: Always unplug the power plug before making any adjustments to the machine. 1 Setting the rotational speed Use the gear lever (5) on the machine side to choose between two speed ranges. Front position (L) for the rotational speed rang 50 to 1100 min-1 Rear position (H) for the rotational speed range 120 to 2500 min-1 Important: Do not change rotational speed ranges (L and H) while the spindle is running!The rotational speed can be adjusted infinitely within the speed range. Use the speed selector switch (6) to finely adjust the rotational speed. 2 Correct rotational speed / cutting speed The choice of the correct cutting speed has an enormous effect on the service life of the tool and on the work results. If the chosen rotational speed is correct, the cutting speed will also be correct. 1 Drilling Rule of thumb: The smaller the hole and the softer the material, the higher the speed of rotation. The table below will help you select the proper speed for the various materials.

Now insert the tapered shank (18) into the bush of the work spindle (4). important: To avoid injury , always use a cloth to hold the routing cutter!To fix the work spindle in position, insert the locating pin (17) into the side of the spindle bush. [. . . ] After finishing the work, return the routing head to the upper position and switch the machine off. Always pull out the power plug before carrying out care and maintenance work!For added protection, identical routing cutters are best kept in a box when not in use. To prevent further damage and injury, please contact our Customer Services department if any faults occur which require more than the normal maintenance. [. . . ]
