Low Battery Indication; Using The Laser - DeWalt DW089-XE Instruction Manual

• To ensure the accuracy of your work, check often to make sure your laser is
calibrated. See Field Calibration Check.
• Before attempting to use the laser, make sure it is positioned securely, on a
smooth, flat surface.
• Always mark the center of the beam created by the laser.
• Extreme temperature changes may cause movement of internal parts that can
affect accuracy. Check your accuracy often while working. See Field Calibration
Check.
• If the laser has been dropped, check to make sure your laser is still calibrated.
See Field Calibration Check.

LOW BATTERY INDICATION

The DW089-XE laser is equipped with a red indicator light (B), as shown in Figure 2.
The red indicator light is located to the left of the on/off buttons (C, D, E).
A flashing red indicator light indicates that the batteries are low and need to be
replaced. The laser may continue to operate for a short time while the batteries
continue to drain, but the beam(s) will quickly dim. After fresh batteries are installed
and the laser is turned on again, the laser beam(s) will return to full brightness and
the red indicator light will stay off. (A flashing laser beam is not caused by low
batteries; see Out of Tilt Range Indicator.)

OPERATION
To Turn the Laser On and Off (Fig. 2)
With the laser off, place it on a flat surface. This model has three ON/OFF buttons,
one for a horizontal laser line (C), one for a vertical laser line (D) and one for a side
vertical laser line (E). Each laser line is powered on by pressing its ON/OFF button.
The laser lines can be powered one at a time or at the same time. Pressing the ON/
OFF buttons again turns the laser lines off.

Using the Laser

The beams are level or plumb as long as the calibration has been checked (see
Field Calibration Check) and the laser beam is not flashing (see Out of Tilt Range
Indicator).
