Maintenance - DeWalt DW089-XE Instruction Manual

OUT OF TILT RANGE INDICATOR (FIG. 3)
The DW089-XE laser is designed to
self-level. If the laser has been tilted so
much that it cannot level itself (average
>4 ° tilt), it will flash the laser beam. The
flashing beam indicates the tilt range has
been exceeded and IS NOT LEVEL (OR
PLUMB) AND SHOULD NOT BE USED FOR
DETERMINING OR MARKING LEVEL (OR
PLUMB). Try repositioning the laser on a
more level surface.
SLOPING THE LASER
If the DW089-XE laser is tilted beyond 15 °
out of level, its laser beams will stay on
longer between flashes to make it easier
to do angled work.
USING THE PIVOT BRACKET (FIG. 2)
WARNING: Position the laser and/or wall mount on a stable surface. Serious
personal injury or damage to the laser may result if the laser falls.
The DW089-XE laser has a magnetic pivot bracket (F) permanently attached to the
unit. This bracket allows the unit to be mounted to any upright surface made of steel
or iron. Common examples of suitable surfaces include steel framing studs, steel door
frames and structural steel beams. The bracket also has a keyhole slot (G) allowing
the unit to be hung from a nail or screw on any kind of surface.
USING THE LASER WITH THE WALL MOUNT (FIG. 4)
The laser wall mount (J) offers more mounting options for the DW089-XE laser. The
wall mount has a clamp (K) at one end which can be fixed to a wall angle for acoustic
ceiling installation. At each end of the wall mount is a screw hole (L), allowing the
wall mount to be attached to any surface with a nail or screw.
Once the wall mount is secured, its steel plate provides a surface to which the
magnetic pivot bracket (F) can be attached. The position of the laser can then be fine-
tuned by sliding the magnetic pivot bracket up or down on the wall mount.

ALIGNING THE VERTICAL BEAM – FINE ADJUST (FIG. 5)
The fine adjustment knob (H) on the top of the DW089-XE is for lining up the vertical
beams. Place the DW089-XE on a flat surface and turn the knob to the right to move
the beam to the right or to the left to move the beam to the left.
Rotating the fine adjustment knob adjusts the entire internal mechanism, maintaining
the 90 ° angle between the two vertical beams.
LEVELING THE LASER
As long as the DW089-XE laser is properly calibrated, the laser is self-leveling. Each
laser is calibrated at the factory to find level as long as it is positioned on a flat
surface within average ± 4 ° of level. No manual adjustments are required.

MAINTENANCE

• To maintain the accuracy of your work, check the laser often to make sure it is
properly calibrated. See Field Calibration Check.
• Calibration checks and other maintenance repairs may be performed by D
service centers.
• When not in use, store the laser in the kit box provided. Do not store your laser at
temperatures below -20 °C (-5 °F) or above 60 °C (140 °F).
• Do not store your laser in the kit box if the laser is wet. The laser should be dried
first with a soft dry cloth.
