3. Operation Instructions

1. Battery Installation

Open the battery door, and put in one 9V battery according to the polarity shown inside. Then snap the battery door back.

Note:

• Remove the battery when the unit is being stored for a long time.

• Replace the battery when the low voltage indicator shows a low battery.

2. Operating Instructions

IMPORTANT: This detector will only work when the laser is in

the pulse mode.

A. Press the Power on/off key: The detector will beep twice and all the symbols will be displayed on the display window. After

0.5 seconds the detector will enter its

detecting mode.

B. Detecting the horizontal laser signal: Put the detector in a vertical position and center the bubble in the horizontal vial with the reception window facing the laser. A down arrow shown on the display window and a lit red light indicates the laser signal is below the detectors on grade

Page 17

6339H_Manuals 10/24/12 12:56 PM Page 17

mark. An up arrow plus a yellow lit light indicates the laser signal is above the detectors on grade mark. A middle sign plus a lit green light indicates the laser signal is on grade.

Note: When the laser signal moves towards the center position, the displayed up or down arrows will decrease in size, until the center single line appears.

C. Detecting the vertical laser signal: Put the

detector in a horizontal position (center the bubble in the horizontal vial) with the reception window and indicator lights facing up. Have the reception window face the unit to receive the vertical laser signal. Left arrow shown on LCD plus a lit red light indicates the laser signal is on the left side of center. A middle sign with a lit green light indicates the laser signal is on the middle position. A right arrow plus a lit yellow light indicates the laser signal is on the right side of center.

D. Press the Power on/off key to power off the detector. The

detector will beep twice for off.

3. Sound Function

Pressing the sound key when the unit is powered-on. This will switch the unit between sound on and sound off,

Sound On

Sound Off

note the sound sign indication on LCD.

Page 18

6339H_Manuals 10/24/12 12:56 PM Page 18

Sound function on:

• If the laser signal is on the top (left) side, then the detector will

give a fast tone.

• If the laser signal is on the bottom (right) side, then the detector

will give a double tone.

• If the laser signal is on the middle, then the detector will have a

solid tone.

4. Automatic Shut-Off Function

When not receiving a laser signal and with no operation of the keys for six continuous minutes, the unit will power off automatically to preserve battery life.

5. Low Battery Indicator Function

• When the power indicator sign is blinking, it

indicates that the battery is low and should be replaced.

• A very low battery will result in an automatic

power-off, which requires the user to replace before continued operation.

8. Self-Check & Fine Calibration

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

calibration of the instrument before each use.

Horizontal line accuracy (horizontal)

1. Place unit on a tripod approximately 5m from a wall. Secure the instrument on the tripod.

2. Face the front of the instrument to the wall, unlock the instrument, and power on the horizontal and vertical laser lines. Make a mark on the wall where the cross-line is displayed. Label this as ‘A’.

3. Make a mark 2.5m from A, along the horizontal laser line, and label as ‘M’.

4. Turn the instrument until the vertical line meets ‘M’, and then make a mark 2.5m from ‘M’, and 5m from ‘A’. Label this mark as ‘B’. Also make a mark on the vertical line where it meets ‘B’.

5. Measure the height distance between ‘M’ and where the horizontal laser line currently sits.

6. If e>1mm, the instrument accuracy is out of tolerance, and calibration is necessary.

Horizontal accuracy self-check (Vertical)

1. Stand up two straight poles/boards 5m from each other, or two walls which are parallel and more than 5m distance.

2. Place the instrument on the tripod, and place in the center of the poles/boards/walls, and level the instrument by adjusting the tripod.

Page 20

6339H_Manuals 10/24/12 12:56 PM Page 20

3. Power on horizontal and vertical laser lines, and make a mark where the cross laser meets target ‘A’. Mark this as ‘A1’.

4. Turn the instrument by 180°, so that the cross line meets target ‘B’. Mark this as ‘B1’.

5. Move the tripod within .6m of target ‘A’. Make a mark where the cross meets target ‘A’, and label as ‘A2’.

6. Rotate the instrument by 180° and make a mark where the cross meets target ‘B’, and label as ‘B2’.

7. Calculate (A1-A2)-(B1-B2) = E. If the absolute value of E is above 1mm, the instrument accuracy is out of tolerance and calibration is required.

Self-check and Calibration

The instrument has two calibration apertures. Aperture ‘A’ adjusts

the horizontal axis. Aperture ‘B’ adjusts the Vertical axis

Notes regarding adjustment:

1. Use a 3mm Hexagon tool for adjustment.

2. The adjustment of each axis may influence the other. When making fine adjustments in the left/right direction horizontally, the front and back direction vertically may change. When adjusting the front/back direction vertically, the left and right direction will possibly change. Adjustments may need to be checked and repeated alternately.

3. The adjustment of the self calibration screw cannot exceed 4 turns in either direction.

4. If the instrument accuracy cannot be adjusted through self calibration, please contact an authorized repair facility, or contact Johnson Level & Tool.

Page 21

6339H_Manuals 10/24/12 12:56 PM Page 21

Dot Accuracy

1. With the laser on its base and set on a flat platform, turn the laser on.

2. Mark the down beam location and use this as your reference point.

3. Locate the up beam and mark its point as ‘A’.

4. Rotate the laser (not moving the base) 180° by swiveling the laser on its base and mark the up beam location as ‘B’.

5. Rotate the laser 90° and mark the up beam as ‘C’.

6. Rotate the laser 180° and mark the up beam as ‘D’. Note: Do not move the base, and always have the down beam in

the same location.

7. Connect the four dots. Connect A to B, and C to D.

8. If the center point ‘E’ is more than 1/8” at 50’, or 1/32” at 24.5’ from points A,B, C, and D, the unit needs to be recalibrated.

Fine Calibration

1. Remove plastic screws on front and left of the laser.

2. With the unit on its base, and on a flat surface, turn the laser on.

3. Return the laser back to its original starting point from the self check.

4. Use a 2mm allen wrench to turn the front adjusting screw to position the laser beam forward and backward.

5. Use the side adjusting screw to position the laser beam left and right.

6. Move the top beam to the intersection of the 4 dots.

Page 22

6339H_Manuals 10/24/12 12:56 PM Page 22

7. Perform another self check calibration as described previously to make sure the laser is calibrated.

8. If the laser is still beyond its accuracy specification, recalibrate the laser again.

9. If laser is still out of calibration, contact Johnson Level & Tool for service.

10. Return the plastic screws, being careful not to over-tighten.

Self-checking the 3 Horizontal Beams

1. As shown in Fig. 1, set the instrument on a tripod or flat platform 50’ from an upright wall. Aim the front beam at the face of the wall. Mark the point projected on the wall by front beam as ‘A’.

2. Turn the instrument clockwise (Fig. 2) to make the point projected by the right laser beam on the same exact line as point ‘A’, and then mark the point as ‘B’.

3. Turn the instrument clockwise (Fig. 3) to make the point projected by the left laser beam on the same exact line as point ‘A’, and then mark the point as ‘C’.

4. The vertical distance between points A, B and C should not exceed 0.125” (3.2mm).

5. If laser exceeds 1/8” at 50’, contact Johnson Level & Tool for service.
