    POWER The Gradelight can be powered from the Li-Ion rechargeable battery or the alkaline battery pack. It can be used while charging – from AC using the included converter, from 12VDC using the optional Power cable, or from a vehicle (cigarette lighter) charging cable. Charging Charge before first use and when battery symbol indicates low.

    Entering a Grade The grade range is from +40% to -10%. Grade can be set in increments as small as .001% using the digit select or rolling counter entry method. The display lights when entering grade. The LCD is color coded to match the grade entry button: green for positive grade and red for negative grade.

  • Page 9: Remote Control Overview

    Remote Control Overview The remote if used primarily to move the beam left or right, within the azimuth range, and to put the laser in standby or locked mode. Since it’s an infrared line-of-site device, there should be no obstructions between it and the laser. It can be pointed at either the front side (through the pipe) or the back of the laser.

  • Page 11: Using The Target

    Using the Target The target can be used for multiple pipe sizes. It features a unique design; the target panel is mounted at the front of the base, not the center. This allows easier viewing at the front of the pipe. It also has a magnetic base for attaching to trench box side wall after pipe setting.

  • Page 14: Autotarget Self-Alignment (Narrow)

    Getting started: NOTE: Before the alignment procedure is started, ensure there is free line-of-sight between the pipe laser and the Auto Target, and that nothing moves through this area during the seeking time. Step 1: AutoTarget inside the pipe: Put the AutoTarget with or without the red target element into the pipe. Proceed to step 2.
  • Page 15 Once the pipe laser's vertical rotational beam hits the AutoTarget’s reception field, the LEFT red LED starts blinking. Thereafter (between 20-80 seconds – depending on the distance) the scan beam stops in the AutoTarget‘s center and switches off. The RIGHT red LED blinks shortly and the pipe laser's main laser beam switches back on and the green ON/OFF LED switches on again.

  • Page 16: Autotarget Self-Alignment (Wide)

    Step 3: Self-alignment procedure: Wide Mode Switch on the AutoTarget by pressing and holding the Red SEEK button and at the same time quickly press the green ON/OFF button. After which release them both at the same time. All LEDs will blink shortly showing the current status of battery current and the green ON/OFF LED stays on along with the two outside red LED’s, this lets you know the AutoTarget is in wide mode.

  • Page 17: Autotarget Troubleshooting

    Step 4: Fine positioning: If you’re not satisfied with the accuracy of the self-alignment, you’re able to fine adjust the alignment of the pipelaser’s beam with the LEFT or RIGHT buttons on the AutoTarget. You may use the pipelaser’s remote or the pipelaser’s keys as well. You may now switch off the AutoTarget and replace it with a standard target.

    Basic Set-up and Operation The steps noted below are illustrated in previous sections. See next section for specific applications. 1. Attach any mounting accessories to the unit, such as the legs, trivet, handle/rod mount, etc. Place the unit in the manhole or pipe at the proper offset and elevation. 2.

  • Page 24 3. Align Transit to Laser – Tilt the transit down and sight on the line pivot LED. On the transit, use the laser centerline knob to adjust the vertical crosshair until it is exactly aligned with the line pivot LED on the laser. Repeat steps 2 and 3 until the crosshair is on the forward manhole marker and the line pivot LED.
  • Page 25 Set-up Methods These instructions describe four ways to set up: height adjustable legs, trivet, rod and crossbrace, or above ground on a tripod. Height Adjustable Legs The adjustable legs can be used to set up in a manhole base, pipe, invert, or open cut.
  • Page 26 2. Attach the leg set with two side legs at the front and the centerline leg at the rear. Set all three legs so the appropriate pipe size mark is aligned with the centerline-of-beam marks beside each leg slot. 3. Slide the unit into pipe and rough level in the cross-axis direction using the cross-axis level vial indicator on the display.
  • Page 27 Trivet Manhole Base Set-up Prepare the laser for use: Attach handle/rod mount, apply power, center the line adjustment, and enter desired grade. Mount the height adjustable rod (center the rod height in its adjustment range) to the trivet. (Figure J) Transfer elevation from the hub to the manhole base.
  • Page 28 Above Ground Set-up Prepare laser for use: mount the sighting scope and attach to a 5/8”-11 tripod. If a dome head tripod is used the laser may be attached directly; to attach to a flat head tripod, use the adaptor. Center the line adjustment, and set grade at exactly zero.

  • Page 32: Using A Blower To Eliminate Refraction

    Using a Blower to Eliminate Refraction Certain conditions can cause refraction and scintillation to occur inside the pipe, with the laser dot appearing to be dancing all around the target. The laser light passes through a medium – air. Anything that disturbs the air will cause the light to scintillate (dance).
