INSTALLATION EXCAVATOR - MODE (OUTSIDE THE TRENCH)
Laser
· Position the rotating laser at a suitable height and power-on.
· The excavator arm and receiver should be positioned to ensure maximum visibility of the laser
beam. This will reduce the necessity to re-sight the rotating laser during the dig.
· Determine the height from the laser plane to the bottom of the trench.
This is the set-up height (H) which is the sum of the distance from the laser plane to the top of the
benchmark (A) plus the distance to the trench base (B).
· Connect the receiver to the side of the excavator arm.
Two options:
a) Magnet connection directly to the arm.
b) Magnet connection of magnetic support (available optionally, ref. 290810) for use with
FMR 800-M/C with clamp connection.
Advantage: allows the receiver to be easily aligned to the laser plane.
· Attach the magnetic support or the receiver to the arm so that it points to the bucket teeth.
(If the bucket is set to the ground with the bottom of the bucket and not with the teeth,
point the magnetic support/receiver to the point where the bucket touches the ground).
· Move the receiver up/down until the green LEDs are flashing (on-level).
· Turn the display of the receiver into the direction of the drivers cabin.
· Select the required accuracy (height indication and bucket tilt).
· Start the excavation. The excavation depth and vertical position is correct if the
receivers green LED's are permanently illuminated.
· It is advisable to make regular checks to maintain correct height.
