9. Application Demonstrations

The 40-6519 can be used for many applications. Some ideas to

enhance the utility of your new laser include:

• Installing wood or metal stud walls. Use horizontally to mark

reference heights on the stud walls for electrical outlets or other items. Use vertically to set plumb, or to layout the location of the wall’s bottom plate.

• Use to lay out tile. The laser can be used both horizontally or

vertically to align wall and floor tile in all directions.

• Use the laser vertically to align the ends of shelving, cabinets, or

stacked photos.

• User the laser horizontally to level shelving, level cabinets, or level

and align rows of photos.

• Use the laser to align tape for pinstriping or other marking

of walls.

• Use the laser outdoors with a detector to grade an area, build

retaining walls (horizontal and vertical mode), layout fencing or posts level (horizontal mode) or straight (vertical mode).

• Use to install drop ceilings

11. Calibration

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

calibration of the instrument before each use.

X- and Y-Direction Accuracy Verification

1. Note X- and Y-direction as indicated on the top of the laser.

2. In an indoor setting, place the laser on a level platform at least 25’ away from a wall. Position the laser so the X-direction is facing the wall.

3. Press the button to power on the laser.

4. Set the lock knob to the “On” position to unlock it.

5. Press the button to change the rotating speed to Low.

6. Mark any point along the top edge of the beam where the beam hits the wall as Point Ax. (Note: This test should be done indoors with dim lighting. It is critical that the laser mark is easily seen.)

7. Rotate the laser 180 degrees.

8. Mark a point where the top edge of the beam hits the wall as Point Bx. This point should be in the same vertical plane as point Ax (directly above, below, or on top of point Ax).

9. Mark the center point between points A and Bx as Point 0x.

10.If the distance between point Ax and Point Bx is more than 3/16” at 25’, the laser is out of calibration. Calibrate the laser by following the steps in the Accuracy Calibration section below. If this distance is < 1/16” at 25’, proceed to step 11 to check the Y-direction accuracy.

1658i-English_Manuals 1/11/17 11:50 AM Page 22

Page 23

11.Position the laser so the Y-direction is facing the wall.

12.Perform Y-direction self-check using the same method as the X-direction (steps 6-10 above) and mark Point Ay, By, and 0y.

13.If the distance between points Ay and By is more than 3/16” at 25’, the laser is out of calibration. Calibrate the laser by following the steps in the Accuracy Calibration section below. If this distance is < 3/16” at 25’, and your X-axis is also within the tolerance listed in Step 10, then your laser is in calibration.

Accuracy Calibration

1. Note: The laser should be turned off and the compensator must be unlocked prior to making any adjustments

2. Remove the adjustment-hole bolts with a #1 Philips screwdriver, and adjust the X direction fine-adjustment bolt in the instrument core with a 3mm hex wrench until the top edge of

1658i-English_Manuals 1/11/17 11:50 AM Page 23

Page 24

the laser line is within 3/32” of Point 0. Loosening this screw will bring the laser line UP as viewed when the X-axis is pointed towards the wall. Tightening the adjustment bolt will bring the laser line DOWN in this orientation.

3. After adjusting the X-direction, adjust the Y-direction using the same method. Loosening the Y direction adjustment bolt will bring the laser line UP the wall in the direction of the Y-axis, tightening will bring the laser line DOWN the wall.

4. After the laser is calibrated, reinstall the adjustment-hole bolts and complete the steps above for X & Y direction accuracy verification to confirm the changes you have made.

Accuracy Self-Check for Plumb Beam

1. After completing the above steps to field adjust the rotary laser output, double check the plumb beam output. Because the optics for the plumb beam are shared with the optics for the rotary, if the rotary is in calibration, the plumb beam should also be in calibration, so this step is really a redundant check; no further adjustment to the plumb beam is possible.

2. Place the instrument horizontally on a rotating tripod head so that the plumb beam strikes the ceiling. The higher the ceiling,

Remove the adjustment-hole bolt Adjust the fine adjustment bolt

1658i-English_Manuals 1/11/17 11:50 AM Page 24

Page 25

the more accurate the check will be. We recommend a minimum height of 10’; 25’ is preferred.

3. Mark the point on the ceiling where the plumb beam hits.

4. Rotate the laser 90 degrees and again mark the spot where the plumb beam hits.

5. Repeat step 4 twice, resulting in a total of 4 marks on the ceiling.

6. The four points should form a circle. Measure its diameter. If this diameter is less than 3/16” at 25’, the laser is in calibration. If the plumb beam is out of calibration, and the rotary beam is within calibration, the laser must be serviced by an authorized Johnson dealer. No further user adjustments are possible. If both rotary and plumb beams are out of calibration, follow the steps above for Accuracy Calibration.

Vial Calibration

1. Adjust the laser so that it projects a perfectly vertical beam on the wall. Mark two points on the wall and use a known calibrated bubble level to validate that beam is vertical. If the vial on the laser reads level, no further adjustments are needed.

2. If the vial needs adjustment, use a screwdriver to remove the vial level adjustment bolt cover.

3. Insert a 2.5mm hex wrench into the adjustment hole to adjust the screw.

1658i-English_Manuals 1/11/17 11:50 AM Page 25

Page 26

4. Rotate the hex wrench to center the bubble. Tightening (clockwise rotation) will move the bubble AWAY from the adjustment screw. Loosening will move the bubble TOWARDS the adjustment screw.

5. After the vial is calibrated, reinstall the vial adjustment bolt cover.
