INTENDED USE

The crossline laser DW089 has been designed to project laser lines
to aid in professional applications. The tool can be used for horizontal
(level), vertical (plumb) and square alignment. The applications range
from layout of walls and windows to installation of framing track.
DO NOT use under wet conditions or in presence of flammable
liquids or gases.
The crossline laser is a professional tool. DO NOT let children come
into contact with the tool. Supervision is required when inexperienced
operators use this tool.

OPERATION

WARNING: Always observe the safety instructions and applicable
regulations.
To Turn the Laser On and Off (fi g. 1)
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.
E. ON/OFF button, side
vertical laser line
F. Magnetic pivot bracket
G. Keyhole slot
H. Fine adjustment knob
I. 1/4" x 20 female thread
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).
OUT OF TILT RANGE INDICATOR (FIG. 2)
The DW089 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 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. 1)
The DW089 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.
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.
