HARDWARE GP 4646053 - Caterpillar

Never look into a laser beam or point the beam into the eyes of other people. Set the laser at a height that prevents the beam from flashing directly into people's eyes.
Set up the laser transmitter so the laser beam is at a zero percent grade and a zero percent cross slope. Refer to the Operation and Maintenance Manual for the laser transmitter instructions on setting the grade and cross slope.Note: Caterpillar recommends the use of a laser transmitter with the following features: automatic self-leveling mode, 600 rpm min rotational speed and automatic out of level shutoff. Read the operator manual and follow the operator manual that is supplied with the laser transmitter. The tripod and the laser should be located at least 46 m (150 ft) away from the machine. The laser should be located in an area so that the laser will not detect reflections or any light source that could disrupt the laser. Set the height of the tripod and the laser transmitter so that the laser beam will strike the laser receiver when the receiver is positioned correctly on the machine. Set the laser high enough so that the cab of the machine will not stop the laser beam from being detected by the laser receiver.
Ensure that the masts are at the lower limit.Note: Keep the height of the laser receivers as low as possible. This will help ensure greater system accuracy during calibration of the AccuGrade - Laser System.
Crushing hazard! Read and understand the instructions and warnings in the Operation and Maintenance manual. Failure to follow the instructions or heed the warnings could cause serious injury or death.
Raise the blade approximately 30 cm (12 inch). Ensure that there is enough room in order to use a level under the edge of the blade.
