Safety Information • Always allow for clearance under the cutting edge of the machine when tuning the system or when switching to automatic control. Insufficient clearance could cause the machine to lift itself off the ground as its cutting edge attempts to achieve the programmed slope. This manual is furnished to you, the owner/operator, as a guide to get the greatest benefit from your Grading Box.
Warranty This Laser Grading Box is designed and manufactured to high quality standards. ATI Corporation, therefore, guarantees this Laser Grading Box to be free from defect in workmanship and materials for one (1) year from purchase date. If the machine is used for rental purposes, the warranty is limited to ninety (90) days. Laser Controls, Vendored Components and Control Valve Parts are warranted separately by their respective manufacturers.

Systems Features and Basic Operation Purpose NOTE: It is the responsibility of the dealer or owner to select, install, and properly operate an automatic control system on this Laser Grading Box within the guidelines of this manual. The Level Best Laser Grading Box is a cost-efficient method for fine grading. Various capacities sized to fit the skid steer or tractor with a choice of automatic control systems are available.
Systems Features and Basic Operation Control Panel – Contains the logic of the automatic control system, processing data from the Laser Sensor and, if equipped, switches controlled by the operator. Use of any laser on a worksite is controlled by OSHA regulations found at 29 CFR 1926.54. Be familiar with these regulations before using any laser beacon used in conjunction with this system. Review and understand all literature provided with the Laser System before operating.
Systems Features and Basic Operation Figure 2. Valve Connection Details Equipment Set-Up Hydraulic Valve The hydraulic valve is mounted on the frame of the Laser Grading Box. It is an electrically-actuated double-acting, single-section valve. Hoses and quick-couplers to attach it the tractor’s auxiliary hydraulics are included with the hydraulic kit. Skid Steer Grading Box 1. Provide power to the Control Panel from the skid steer's electrical system. Usually this involves a direct hookup to the battery.
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 cylinders set so the tires of the Laser Grading Box are on the ground. Cables must be securely fastened and pinch/rubpoints eliminated. Do not fasten to hydraulic lines which may operate at high temperatures. Ensure sufficient cable length to allow movement of the machine.
Systems Features and Basic Operation Figure 5. Components of the Automatic Control System on a Tractor Job Site Set-Up 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. The following are guidelines for setting up a Rotating Laser for both level job sites and sloped job sites: 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.
Systems Features and Basic Operation Set-Up for Level Grading If the job site is to be level, the set-up of the Rotating Laser is simple. Since no slope is required in either axis, the Rotating Laser does not need to be aligned. The Rotating Laser will provide a level plane of laser light in all directions. 1. Locate the Rotating Laser following the guidelines above. 2. Apply power to the Rotating Laser.
Systems Features and Basic Operation 4. Roughly align one of the axis to the grade stakes by sighting over the top of the Rotating Laser (Refer to Figure 7). • If the Rod Eye Receiver indicates the plane of laser light is too high or too low, have a second person rotate the Rotating Laser on the tripod in small steps until the Rod Eye Receiver indicates “On Grade.” 5. Set both the counters on the Rotating Laser to the required percent of grade (If needed, see the Rotating Laser Operation Manual). 7.
Systems Features and Basic Operation Benching 7. Align the plane of laser light. a. Align the bottom of a Grade Rod to the mark on the far grade stake. 1. Move the machine to an area which is close to finish grade or, using the manual controls on the control system, grade a small area close to finish grade. b. Check the Rod Eye Receiver. • If the Rod Eye Receiver indicates “On Grade,” the plane of laser light is aligned at the correct slope.
Systems Features and Basic Operation 2. Find an area to be graded that is close to specified grade. Start the skid steer or tractor, engage the auxiliary hydraulics and move the unit to that location. Manually raise or lower the Laser Grading Box’s cutting edge until it is even with the bottom of the measuring pole when the Rod Eye is emitting the “On Grade” tone or resting on the ground if already at grade.
Troubleshooting Symptom Laser Grading Box does not raise or lower. Potential Cause Control Panel not turned on. Remedy Apply power. No hydraulic flow to Laser Grading Box. Ensure hydraulic control handle of skid steer or tractor is in correct position. Ensure auxiliary hydraulics are ON or in continuous flow mode. Cables not connected correctly. Refer to the automatic control system documentation. Move directional valve spool manually using the overrides on the end of the directional valve.
Troubleshooting Symptom Box has trouble staying on grade. Potential Cause Rotating Laser out of range. Remedy Ensure Laser Sensor is within specified operating range of Rotating Laser. Laser beam being reflected. Ensure Rotating Laser’s light is not reflecting off other surfaces (windows, windshields, mirrors, etc.) causing multiple readings by the Laser Sensor. Multiple laser beams. Ensure that there are no other lasers operating on the job site or nearby. Laser deadband set too narrow.

Specifications and Maintenance Maintenance Calibration Perform periodic calibration checks of the Rotating Laser System as outlined in its Operation Manual to ensure accurate performance. The rugged and durable automatic control system is built to last, but as with all equipment, a few minutes of routine care, maintenance, and cleaning can extend the life of the system.
