WS-30 WM 4. STARTUP AND OPERATION 4.1. Handle adjustment The milling machine handle may be adjusted in three axes so the operator may adapt it to their needs. To adjust, loosen the domed nuts (1) and screws (2) and (3) using 22 mm flat wrench.
WS-30 WM 4.2. Milling depth adjustment Unplug the power cord. Release the lever (1). Rotate the knob (2) so the scale (3) shows the milling depth “d” (maximum 11 mm (7/16”) and minimum -1,5 mm (-1/16”)). Lock the lever. The depth change is 0.2 mm (1/64″) per graduation or 3 mm (1/8″) per one full turn of the knob.
WS-30 WM 4.3. Cutting inserts installation Unplug the power cord. Position the milling machine with head up. Unlock the lever (1) and rotate knob (2) to disassemble the whole guide unit. CAUTION: do not unscrew the lever (1) completely. It may cause dropping the clamping element.
WS-30 WM Prepare screws (1) covered with delivered grease. Put the insert (2) in the socket, press it down and fix with screw, using T15 torx screwdriver. Make sure that the whole bottom of the insert touches the socket. CORRECT ✓...
WS-30 WM 4.5. Turning the guide unit Unplug the power cord. Release the lever (1). Hold the milling depth knob (2) so it does not rotate in relation to the guide unit and turn the guide unit to the desired position (3).
WS-30 WM 4.6. Preparation for machining Set the required milling depth. Then use the speed knob to set the rotational speed. Material Rotational speed Setting 3-6 Structural steel of standard quality, quality steel (3100-5850 rpm) The speed knob allows for control of the rotational speed in the range of 1800-5850 rpm.

WS-30 WM Start from low milling depth values and increase it gradually. Press the guide unit towards the material surface. Guide the machine in direction indicated by the arrow on the guide unit (1). If an overload occurs, the motor shuts off. This may occur when depth is too large for the hardness of material or when the cutting inserts are dull.
