Installation - Excavating
NOTE: For all excavation operations, always take a sample reading
with the bucket "on-grade" and check to ensure the elevation is
correct. For all grading operations, make a sample pass with the
blade "on-grade" and check to ensure the elevation is correct.
Magnetic Mount Installation - For excavators and backhoes,
determine where the mount will be located on the machine so that
when the receiver is attached, it will intersect the laser beam. Refer
to the previous installation instructions if the Angle Compensation
for Excavation (ACE) is to be used. 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 or in the necessary set-up position.
CAUTION: Strong magnetic field; Do not position fingers next to
magnets.
To remove the magnetic mount, first remove the receiver from the
mounting pole. Use a scrap piece of wood or other long object as
a pry bar if necessary. 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.

Operation - Secondary Functions
While the unit is on, pressing and holding the power switch and then pressing
the touch panel switches will activate secondary or "shift" functions which
are indicated by the symbols above the switch.
Laser Out-of-Level: This function is for use with lasers that have
the ability to indicate that they are out-of-level by changing the RPM
of the laser. Two speeds of 140 RPM and 300 RPM are available
as well as out-of-level turned off. Press and hold the power switch and then
press the plumb switch to cycle through the options of 140 RPM, 300 RPM,
and off. The LCD will indicate which is selected. "No display" on the LCD
indicates out-of-level is disabled. When the laser RPM drops to the selected
laser out-of-level speed, an "X" symbol will appear on the LED grade display
and on the LCD symbol.
Beam Averaging: Press and hold the power switch and then press
the on-grade location switch to select and cycle the laser beam
averaging function. Selection "Off" - no display - chooses adaptive
averaging. In this mode the receiver applies the highest level of averaging
appropriate for the laser rotation speed. A selection of one means every beam
strike is processed. Selecting two or four creates a rolling average of every two
or four beam strikes. This stabilizes the LED display in unstable laser set-ups
such as windy conditions or over long distances.
