3.1 Change the start point for the trolley motion
The start point value should be adjusted so that the trolley
motion is as low as possible when the trolley motion knob is
in the zero position, i.e. in the middle of the left and right end
positions.
A too low value results in the need to turn the knob further
from the zero position before the trolley motion starts.
A too high value results in the trolley motion being too high
when the knob is turned from the zero position.
IMPORTANT! Wear to the proportional valve and hydraulic
motor can result in the need to adjust the start point value.
State the start point value:
• Press OK when the part menu is shown.
The display shows: CHANGE START POINT and a
percentage value.
• Scroll using the arrow keys to state the required start
point. Hold the arrow keys held down to increase the
scrolling speed. The scale is graduated from 1-100 %.
• Press OK to confirm the selection.
• Press the down arrow to continue to the next part menu.
3.2 Change the end point for the trolley motion
The end point value should be adjusted so that the trolley
motion speed is as high as possible when the trolley motion
knob is turned to the right.
A too low end point value results in the full trolley motion
speed never being reached.
State the end point value:
• Press OK when the part menu is shown.
The display shows: CHANGE END POINT and a
percentage value.
• Scroll using the arrow keys to state the required end point.
Hold the arrow key held down to increase the scrolling

3.3 Change the start point for depth feeding
The start point value should be adjusted so that the depth
feeding is as low as possible when the depth feeding knob is
in the zero position, i.e. in the middle of the left and right end
positions.
A too low value results in the need to turn the knob further
from the zero position before the depth feeding starts.
A too high value results in the depth feeding being too high
when the knob is turned from the zero position.
State the start point value:
• Press OK when the part menu is shown.
The display shows: CHANGE START POINT and a
percentage value.
