Installation - Excavating

Out of Trench Set-Up

Set the laser up in an appropriate location for receiver visibility and efficient

machine operation and turn it on.

Place the bucket in the grade checking position and situate the machine

so a measurement can safely be obtained on the dipper arm. The dipper

arm may be set more horizontal to the ground for convenient measure-

ments if necessary.

Determine the distance from the laser to the bottom of the trench (L). This

is the set-up length. The length is the height of the instrument (HI) plus the

depth of cut from the benchmark to the bottom of the trench (C).

Mount the mast on the side of the dipper arm.

Position the receiver so the set-up length (L) is the distance from the

bucket ground contact point to the offset on-grade symbol on the back

label. (Set up to center on-grade symbol if center on-grade will be used).

Turn the receiver on and select offset on-grade and the desired deadband.

(Select center on-grade if set to center symbol).

Begin to excavate. Take grade readings with the bucket in the grade

checking position and the LED's solid.

Take a sample reading with the bucket "on-grade" and check to ensure

the elevation is correct.

For excavators and backhoes, determine where the mount

will be located on the machine so that when the BULLSEYE

is attached, it will intersect the laser beam. Ensure the

area of the machine is clean and free of oil and grease.

Angle the mount so the top edge of the top magnet will be

positioned first. Holding the mount by the pipe with both

hands, place the top edge of the magnet on the machine.

Slowly move the bottom magnet towards the machine so

the mount remains plumb.

CAUTION: Strong magnetic field; Do not posi-

tion fingers next to magnets.

Attach and set-up the BULLSEYE in the normal manner as described on

the previous pages.

Remove the receiver from the mounting pole prior to removing the

magnetic mount. Use a scrap piece of wood or other long material as a

pry bar. Insert the pry bar in between the magnetic mount pole and the

machine. Pry the mount sideways to loosen the magnetic hold. Once the

magnetic hold is loosened, the mount can be easily taken off the machine

by hand.

NOTE: For extendable dipper arms - if the mast is mounted

to the dipper arm section that moves with the bucket, grade

can be checked with the dipper arm extended to any

position. If the mast is mounted to the dipper arm section that does not

move with the bucket, grade can only be checked when the dipper arm is

in the exact set-up position.
