LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship under normal use and service. The warranty period is three years and
begins on the date of shipment. Parts, product repairs, and services are warranted for 90 days. This warranty extends only to the original buyer or end-user
customer of a Fluke authorized reseller, and does not apply to fuses, disposable batteries, or to any product which, in Fluke's opinion, has been misused,
altered, neglected, contaminated, or damaged by accident or abnormal conditions of operation or handling. Fluke warrants that software will operate
substantially in accordance with its functional specifications for 90 days and that it has been properly recorded on non-defective media. Fluke does not warrant
that software will be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers only but have no authority to extend a greater or
different warranty on behalf of Fluke. Warranty support is available only if product is purchased through a Fluke authorized sales outlet or Buyer has paid theE
applicable international price. Fluke reserves the right to invoice Buyer for importation costs of repair/replacement parts when product purchased in one country
is submitted for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair, or replacement of a defective product which is
returned to a Fluke authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center to obtain return authorization information, then send the product to that
service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination). Fluke assumes no risk for damage in transit. Following
warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that failure was caused by neglect, misuse,
contamination, alteration, accident, or abnormal condition of operation or handling, including overvoltage failures caused by use outside the product’s specified
rating, or normal wear and tear of mechanical components, Fluke will provide an estimate of repair costs and obtain authorization before commencing the work.
Following repair, the product will be returned to the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges
(FOB Shipping Point).
THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE
LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, ARISING FROM ANY
CAUSE OR THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or consequential damages, the
limitations and exclusions of this warranty may not apply to every buyer. If any provision of this Warranty is held invalid or unenforceable by a court or other
decision-maker of competent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

•
Do not look directly into the laser with optical
tools (for example, binoculars, telescopes,
microscopes). Optical tools can focus the laser
and be dangerous to the eye.
•
Remove the batteries if the Product is not used
for an extended period of time, or if stored in
temperatures above 50 °C. If the batteries are
not removed, battery leakage can damage the
Product.
•
Do not use the Product if it operates
incorrectly.
•
Do not look into the laser. Do not point laser
directly at persons or animals or indirectly off
reflective surfaces.

Level
To identify new level and grade marks:
1. Put the bottom of the Product on a stable surface.
2. Turn the Product around on its center until the
horizontal laser points to the target area. See Figure 1.
3. Place a mark at the level or grade point on the target
area.
4. Repeat steps 2 and 3 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.
Figure 1. New Level Mark
To determine if an existing item is level:
1. Point the horizontal laser at the target area.
2. Measure the distance from the item to the laser. See
Figure 2.
3. Repeat step 2 at various distances from the Product.
If the measurements are the same from each distance
from the Product, the condition is level.

Plumb
The Product can send plumb marks up, down, or
cantilevered over the edge of a building or shaft opening.
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 3.
3. Place a mark at the point where the up laser intersects
the target area.
To identify new plumb marks on a floor, repeat the steps
above but interchange the down and up lasers.
Note
Use the floor stand with the Product to increase the
sight angle of down laser.

To determine if an existing item is plumb:
1. Point either the up or down laser at the target area.
2. Measure the distance from the item to the laser. See
Figure 4.
3. Repeat step 2 at various distances from the Product.
If the measurements are the same from each distance
from the Product, the item is plumb.

Check Accuracy of the Product
Periodically check the accuracy of the Product.
Check Accuracy of Level
To check the accuracy of the level:
1. Find a horizontal site that is almost level, preferably a
concrete slab, that is ≥7.62 m (25 ft) wide with two
opposing walls to use as targets. You can also use
scrap wood as targets. See Figure 5.
2. Place the Product about 15 cm (6 in) from target .
3. Point the horizontal laser at target .
4. Place a mark at the point where the horizontal laser
intersects the target area.
5. Turn the Product 180 ° on its center so that the
horizontal laser intersects with target .
6. Place a mark at the point where the horizontal laser
intersects the target area.
7. Repeat steps 2 through 6 with the Product 15 cm from
target .

8. Measure the distance between mark and mark
on target and mark and mark on target .
If the distances are the same, the laser is level.
9. If the distances are not the same, subtract the lesser
measurement from the greater measurement and divide
by two to calculate the difference of error.
If the distance is ≤6 mm @ 30 m, the laser is within
calibration accuracy.

Check Accuracy of Plumb
To check the accuracy of the plumb:
1. Find a site that has a ≥3.05 m (10 ft) vertical height.
2. Place a cross mark at the bottom of the site.
3. Center the down laser on both axes of the cross mark.
See Figure 6.

Figure 6. Plumb Accuracy
4. Place a cross mark at the point where the up laser
intersects the target area at the top of the site.
5. Turn the Product 180 ° on its center.
6. Repeat step 3 and step 4.
If the first and second cross marks on the target area at
the top of the site are the same, the laser is plumb.
7. If the cross marks are not the same, measure the
distance between the center points of the two cross
marks and divide by two to calculate the difference of
error.
If the distance is ≤6 mm @ 30 m, the laser is within
calibration accuracy.
Maintenance
The Product does not require maintenance but treat the
Product as a calibrated instrument. Do not drop the Product.
 Warning
To prevent eye damage and personal injury, do not
