Once all preparatory work for milling has been completed, the planer is ready for op-
eration and a truck is parked below the upper conveyor to receive milling debris, the
stationary machine is lowered to the required depth.
- Carefully lower the stationary machine by pressing the switches (74 + 73) until the
milling drum makes gentle contact with the working surface.
- Set the milling depth indicators (A) on both sides of the machine to zero.
- Press the switches (74 + 73) again to lower the machine carefully down to the de-
sired milling depth paying careful attention to the milling depth indicators.
- Set desired milling speed by adjusting the setting of the drive lever (70). The ma-
chine starts to move when the drive lever moves out of its central position.
- If necessary, adjust the speed of the upper conveyor using the preselector (25).
- If necessary, guide the upper conveyor using the control lever (71).
The automatic function for water spraying system and upper conveyor is engaged as
soon as the drive lever moves out of its central position and is disengaged automati-
cally as soon as the machine is stopped.
