Model No. 40-6680
Instruction Manual
Congratulations on your choice of this Self-Leveling Five-Beam Laser
Dot. We suggest you read this instruction manual thoroughly before
using the instrument. Save this instruction manual for future use.
This tool emits five laser beams, which projects a series of visible points
on surfaces around the product (i.e. left, right, front, up, and down).
Beam visibility depends upon lighting conditions in the work area.
This is a Class IIIa laser tool and is manufactured to comply with CFR
21, parts 1040 .10 and 1040 .11 as well as international safety rule

3. Safety Instructions
Please read and understand all of the following instructions, prior
to using this tool. Failure to do so, may void the warranty.
ATTENTION IMPORTANT
• Read all instructions prior to operating this laser tool. Do not remove any labels from tool.
• Do not stare directly at the laser beam.
• Do not project the laser beam directly into the eyes of others.
• Do not set up laser tool at eye level or operate the tool near a reflective surface as
the laser beam could be projected into your eyes or into the eyes of others.
• Do not place the laser tool in a manner that may cause someone to unintentionally
look into the laser beam. Serious eye injury may result.
• Do not operate the tool in explosive environments, i.e. in the presence of gases or
flammable liquids.
• Keep the laser tool out of the reach of children and other untrained persons.
• Do not attempt to view the laser beam through optical tools such as telescopes as
serious eye injury may result.
• Always turn the laser tool off when not in use or left unattended for a period of time.
• Remove the batteries when storing the tool for an extended time (more than 3 months)
to avoid damage to the tool should the batteries deteriorate.
• Do not attempt to repair or disassemble the laser tool. If unqualified persons attempt
to repair this tool, warranty will be void.
• Use only original ohnson®parts and accessories purchased from your ohnson®
authorized dealer. Use of non- ohnson®parts and accessories will void warranty.

6. Operating Instructions
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Battery Installation
Note: Always check to be sure that the on/off switch is in the off
position before removing and replacing batteries.
1. As shown in fig. 3, remove battery cover.
2. Put three “AA” alkaline batteries into the
battery compartment noting polarity (as
shown). Note: Remove white sensormatic
tag before installing the batteries.
3. Re-attach the battery cover.
Note: Used (discharged) batteries are hazardous waste and
should be disposed of properly.
Using the Instrument
1. Place product on a relatively smooth, flat, and level surface.
Note: Product must be within ±4.5° of level for self-leveling feature
to function properly. Greater than 4.5° will result in an alarm
condition (flashing laser and intermittent beeping sound).
2. Rotate on/off switch fully clockwise. This will release the self-leveling
locking mechanism and turn unit on.
3. Turn unit off by rotating on/off switch fully counter clockwise. This
will engage the self-leveling locking mechanism and turn unit off,
ensuring that the unit will not get damaged when moved or stored.

7. Using the Product
This laser level was designed for various mounting applications.
1. Position laser base so laser beam shoots
between the feet of the base for plumb
applications.
2. Base top being rotated to shoot the laser
beam down the back of the base.
3. Position base by rotating top to shoot beam
down the back of the base. Ideal for use
with metal track.
4. Rare earth magnets located on base allows
the base to attach to metal surfaces.

8. Self-Check & Fine Calibration
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
8©2010 Johnson Level & Tool - Rev. 1
Self-Check Calibration
1. With the laser on its base and set on a flat platform inside a room,
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 position A.
4. Rotate the laser (not moving the base) 180º by swiveling the laser
on its base and mark the up beam location as position B.
5. Rotate the laser 90º and mark the up beam location as position C.
6. Rotate the laser 180º and mark the up beam location as
position 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 12.5’ 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 on a flat platform, turn the laser on.
3. Return the laser back to its original starting point when
self-checking the laser.
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 shown in
Fig. A of self-check calibration.
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 ohnson Level & Tool for
service.
10. Return the plastic screws being careful to not over tighten.

Self-Checking the 3 Horizontal Beams
1. As shown in Fig. 9.1, set up the instrument on the tripod or flat
platform 50 ft. (9.1m) 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. 9.2) to
make the point projected
by right laser beam on
the same exact line as
point A, and then mark
the point as B.
3. Turn the instrument counterclockwise (Fig. 9.3) to make the point
projected by 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 ohnson Level & Tool
for service.
