Systems Features and Basic Operation
Figure 5. Components of the Automatic Control System on a Tractor
NOTE: “P” means pressure (supply) and “T” means tank (return). Refer to the tractor Owner’s Manual for identifying the “P” and “T” Auxiliary Hydraulic Ports.
6.Insert the mast pole in the holder until it rests at the bottom of the tube. Tighten the tee handle to secure the mast. Clamp the Laser Sensor near the top of the mast so it is higher than any local obstruction including the tractor cab or fall protection devices. (Refer to Figure 5).
Cables must be securely fastened and pinch/rub- points eliminated. Do not fasten to hydraulic lines which may operate at high temperatures. Ensure sufficient cable length to allow movement of the machine.
7.Connect the various cables to the control system components.
8.If possible, set the automatic control system to manual mode to prevent unintended movement of the Laser Grading Box.
Always have system in Manual setting when not operating the tractor.
Job Site Set-Up
The following are guidelines for setting up a Rotating Laser for both level job sites and sloped job sites:
•Choose a location for the Rotating Laser where obstructions, such as trees and buildings, can not block the plane of laser light. The Laser Sensor needs to be able to sense the plane of laser light at all times.
•Whenever possible, set up the Rotating Laser and the Laser Sensor at a height above the machine’s cab. This prevents the cab or roll- over structure from blocking the plane of laser light as the machine moves around the job sites.
•Be sure the Rotating Laser and Laser Sensor are operating in compatible modes with a head speed that is recognized by the other device.
