6. Operating Instructions

IMPORTANT: It is the responsibility of the user to verify the

calibration of the instrument before each use.

Battery Installation

Remove battery door by rotating it counterclockwise, and put in two alkaline “AA” batteries according to the illustrated polarity requirements, and then install the battery door by rotating it clockwise. Note: Used (discharged) batteries are hazardous waste and should be disposed of properly.

Leveling Base Usage

1. Install the leveling base by screwing the attachment bolt clockwise into 1/4" thread hole at the bottom of the instrument.

2. Level the instrument by rotating two leveling screws.

7. Using the Product

Power On/Off

1. Press power switch to project laser line or dot.

2. Press power switch again to shut off laser output.

from a dot to a line, or line to a dot. Rotating wedge lens counter-clockwise, while in line mode, rotates line from horizontal to vertical, or vice versa.

Note: The rotating head can be turned only in the direction indicated by arrow sign.

8. Self-Check & Fine Calibration

IMPORTANT: It is the responsibility of the user to verify the

calibration of the instrument before each use.

Checking Vials

Start by making sure that the vials are accurate. This is done by placing the level on a flat surface and noting the position of the vial. Rotate the level by 180 degrees (on the same gauging edge) and observe that the bubble is in the same position.

Calibrating Vials

To access the calibration screws remove the stickers located to the right and left of the vial at the top of the unit. First, adjust the calibration screws to move the bubble back to center taking out half of the error in the vial. Rotate the level 180° on the same gauging edge and move the bubble to center. Repeat this process until the error is entirely removed and the bubble stays in the center. Plumb vial and 45° vial cannot be calibrated.

Checking Laser

Once the vials are accurate, laser accuracy can be verified (near target, far target method). Start by placing the unit on a flat surface and aim the laser at a stationary target. Position the unit/target at close range and note a reference point on the target. As the unit is moved away from the target, such that alignment of the laser to the target is fixed, and the only variable is distance, the accuracy of the laser can be verified/calibrated.

Calibrating Laser

There are set screws on the side and bottom of the unit that provide calibration for the laser.

For vertical calibration, use underside screws, tightening the front screw to adjust up and tighten the rear to adjust down.

For horizontal calibration, use two screws on the side of the part number and date code. Tighten the front screw to adjust right. Tighten the back screw to adjust left.
