Systems Features and Basic Operation
3.After installation, ensure that the Laser Grading Box is level. The loader arms must be completely lowered and the bucket cylin- ders set so the tires of the Laser Grading Box are on the ground.
Verify that the Laser Grading Box is level by observing that the main frame is horizontal to the ground. Turn the skid steer engine
OFF when connected.
4.Mount the Control Panel on the bracket attached to the hydraulic valve.
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.

5.Connect the Laser Grading Box’s hydraulic hoses with quick couplers to the auxiliary hydraulic ports of the skid steer. The Laser Grading Box’s hydraulic manifold is marked “P” and “T” where the pressure and return (tank) hoses connect.
NOTE: “P” means pressure (supply) and “T” means tank (return). Refer to the skid steer 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 skid steer cab or fall protection devices. (Refer to Figure 3).
Always have system in Manual setting when not operating the skid steer.
Tractor Grading Box
1.Provide power to the Control Panel from the tractor's electrical system. Usually this involves a direct hookup to the battery.
2.The Laser Grading Box should be positioned on a level area for attaching to the tractor.
Start the tractor and back up to the Laser
Grading Box. Attach the unit with the hitch pins supplied.
3.After installation, ensure that the Grading Box is level. Set the pitch of the Laser Grading Box by adjusting the top and lower links.
Verify that the Laser Grading Box is level by observing that the main frame is horizontal to the ground. Turn the tractor engine OFF when connected.
4.Mount the Control Panel on the right rear fender of the tractor or other easily acces- sible location.
5.Connect the Laser Grading Box’s hydraulic hoses with quick couplers to the tractor quick couplers. The Laser Grading Box’s hydraulic manifold is marked “P” and “T” where the pressure and return (tank) hoses connect.
