Checking Accuracy –
GB
Vertical Beam (See Figure
Checking the vertical (plumb) calibration of the laser can be
most accurately done when there is a substantial amount of
vertical height available, ideally 30' (9m), with one person on
the floor positioning the laser and another person near a ceiling
to mark the position of the beam. It is important to conduct
a calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.
1. Place the laser on a smooth, flat, stable surface that is level
in both directions and turn on both vertical beams (Figure
#1).

beams line up with the marked lines on the level surface

Checking 90º Accuracy Between Vertical Beams
(DCE089R/G) (See Figure
Checking 90º accuracy requires an open floor area at least 10m
x 5m (33' x 18'). Refer to Figure 10 for the position of the laser
at each step and for the location of the marks made at each
step. Always mark the center of the beams' thickness.
1. Set up the laser on a smooth, flat, stable surface that is level
in both directions and turn on the side vertical beam.

Troubleshooting
The Laser Does Not Turn On
• Make sure AA batteries (when used) are installed correctly
according to (+) and (–) on the inside of the battery door.
• Make sure the batteries or rechargeable pack are in proper
working condition. If in doubt, try installing new batteries.
• Make sure that the battery contacts are clean and free of
rust or corrosion. Be sure to keep the laser level dry and use
only new, high-quality, name brand batteries to reduce the
chance of battery leakage.
• If the laser unit is heated above 50 ˚C (120 ˚F), the unit will
not turn on. If the laser has been stored in extremely hot
temperatures, allow it to cool. The laser level will not be
damaged by pressing the on/off button before cooling to its
proper operating temperature.
