2.2 Change the end point for the blade
The end point value should be adjusted so that the
blade rotation is as high as possible when the blade
rotation knob is turned to the right.
A too low value results in full power from the hydraulic
unit 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 speed. The scale is graduated from 1-100 %.
• Press OK.
• Press the down arrow to continue to the next part
menu.
2.3 Change the ramp time for the blade
The ramp time value states how fast the blade's speed
of rotation shall change when the blade rotation knob
is turned.
A too low value means the blade motor's hydraulic
system will start to self-oscillation.
State the ramp time value:
• Press OK when the part menu is shown.
The display shows: CHANGE RAMP TIME and the
time in seconds.
• Scroll using the arrow keys to state the required ramp
time. Hold the arrow key held down to increase the
scrolling speed. The scale is graduated from 0.0 to
9.9 seconds.
• Press OK.
• Press the down arrow to continue to "Back to the
menu".
This sub-menu contains setting options for blade feed,
both horizontally and depth.
The sub-menu consists of five part menus:
3.1 Change the start point for the trolley motion
3.2 Change the end point for the trolley motion
3.3 Change the start point for blade motion
3.4 Change the end point for blade motion
3.5 Change the ramp time for the feed
Work procedure for wall sawing
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.
NOTE!
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.
• 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 speed. The scale is graduated from 1-100 %.
• Press OK.
• Press the down arrow to continue to the next part
menu.
