Installation - Excavating

Out of Trench Set-Up - Bucket Extended

Fully retract the bucket cylin-

der and position the machine 

so a measurement can safely 

be  obtained  on  the  dipper 

arm.
Set  the  laser  up  and  turn 

it on.
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).

Standard Plumb:

  Mount the mast on the side of the dipper arm so it 

points 

to the bucket teeth

 as illustrated above.

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

teeth to the offset on-grade symbol on the back of the receiver. (Set up to the 

center on-grade symbol if center on-grade will be used).
Turn the receiver on and select standard plumb mode, 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  retracted  and  the 

LED's solid.

ACE mode: 

Follow the procedure above except the set-up length is the dis-

tance from the 

bucket teeth

 to the 

center on-grade

 symbol on the back of 

the receiver.
Enter the ACE mode. Press and hold the plumb switch to scroll up the set-up 

length scale and release the switch when the lit LED is closest to the measured 

set-up length. The LED will blink to confirm the setting.
Select the desired deadband and begin to excavate.
Take grade readings with the bucket retracted and LED's solid.
