waste.
Indicates a Class 2 laser. DO NOT STARE INTO BEAM The following text may appear with the symbol
on the product label: “IEC/EN 60825-1:2014. Complies with 21 CFR 1040.10 and 1040.11 except for
deviations pursuant to Laser Notice 50, dated June 24, 2007.” In addition, the following pattern on the
label will indicate wavelength and optical power: λ = xxxnm, x.xxmW.
Note
In colder climates, the Product needs sucient time to warm up to achieve the stated accuracy
measurements. Turn on both the horizontal and vertical lasers and wait 3 minutes before you take a

The self-leveling feature, keeps the lasers visible when the Product tilts ≤4 °
in any direction.
When the Product tilts >4 ° in any direction, the lasers do not show. The
Laser indicator LED stays green to indicate that when you return the Product
to an upright position, the lasers show again.
7Laser lock position
Keeps the lasers visible even when you tilt the Product >4 °. The lasers blink
twice every 5 seconds to indicate the self-leveling feature is disabled. Use to
align items diagonally such as a stair rail.

Use the Product to layout reference points and to make sure conditions are level and plumb.
W* Warning
To prevent eye damage and personal injury, do not look into the optical windows when the Laser
indicator LED shows green.
New Horizontal or Diagonal Alignment
Note
To nd diagonal alignment, use the lock feature.
To identify new level or grade marks:
1. Put the bottom of the Product on a stable surface.
2. Turn on the Product and aim the forward laser at the target area. See Figure 2.
3. Place a mark at the level or grade point on the target area.
4. Repeat for each point as needed.
Note
When the Product is mounted on a tripod, make sure the tripod head is perfectly level. Errors in marks can
result if a tripod is out of level.

Existing Horizontal or Diagonal Alignment
To determine if an existing item is level or aligned:
1. Put the bottom of the Product on a stable surface.
2. Point the forward laser at the target area.
3. Measure the distance from the item to the laser at various distances from the Product. See Figure 3.
If the measurements are the same, the item is level or aligned.

Plumb Marks
The Product sends plumb marks up and down.
New Plumb Marks
To identify new plumb marks on a ceiling or roof:
1. Place a cross mark on the point to be transposed.
2. Center the down laser over the cross mark. See Figure 4.
3. Place a mark at the point where the up laser intersects the target area.
To identify new plumb marks on a oor, repeat the steps above but interchange the down and up lasers.
Note
Use the oor stand with the Product to increase the sight angle of the vertical down laser.

Square Marks (5R, 5G Only)
Use the forward and horizontal lasers to create new square marks or to determine if an existing item is square.
To layout a new square for a wall or staircase (See Figure 6):
1. Mark a vertical line on a wall.
2. Center the forward laser on the line on the wall.
3. Place the pendulum target on the oor and align the horizontal laser with the center vertical line on the pendulum
target.
4. Place a mark on the oor below the point of the pendulum target.
5. Move the Product either closer to or farther away from the wall and redo the procedure to make another mark on the
oor.
6. Draw a line to connect the two marks. The new line is perpendicular to the wall.

Checking the Horizontal Leveling Accuracy
A free measuring distance of 15 ft on a rm surface in front of two walls A and B is required for the check.
1. Mount the tool onto a tripod, or place it on a rm and level surface 6'' from wall A. Switch the tool on and set the lock to
"unlock".
AB
15 ft (4.57m)

2. Sketch a vertical line on wall A and point the front laser so it lines up with the sketched line. Allow the tool to level in.
Mark this point on the wall (point 1).
AB
180°
21
3. Turn the tool by 180°, allow it to level in and mark the front point of the laser on the opposite wall B (point 2).
4. Without turning the tool, position it 6'' from wall B. Switch the tool on and allow it to level in.

5. Align the height of the tool (using a tripod or by underlaying, if required) in such a manner that the front point of the
laser is projected against the previously marked point 2 on the wall B.

6. Without changing the height, turn around the tool by 180°. Direct it against the wall A in such a manner that the vertical
laser line runs through sketched vertical line with point 1.
Allow the tool to level in and mark the cross point of the laser on wall A (point 3).
7. The di󰀨erence of both marked points 1and 3 on wall A results in the actual height deviation of the tool alongside
the lateral axis.
On the measuring distance of 2 x 15ft = 30ft, the maximum allowable deviation is: 30ft x ±0.00394in/ft = +/- 1/8” (3
mm)
Thus the di󰀨erence “d” between points 1and 3 must not exceed 1/8 in (max.).

Plumb Accuracy
To check the accuracy of the plumb:
1. Find a site that has a known vertical height X. Put unit on oor stand and place on the oor.
2. Place a cross mark at the bottom of the site. 1
3. Center the down laser on both axes of the cross mark. See Figure 7.
