THE LASER IS PROJECTING 2 LASER LINES WHEN THE
LASER HEAD IS ROTATED.
Take the laser to a D WALT service center for calibration.
E
THE POWER LED LIGHT IS FLASHING , THE ROTARY HEAD
HAS STOPPED SPINNING AND THE LASER DIODES HAVE
SHUT DOWN.
This indicates that the batteries need to be replaced. TIP: See
"Installing Batteries" section.
THE BUMP SENSOR WARNING LED LIGHT IS FLASHING.
See "Bump Sensor" section for operating instructions.
THE BUMP SENSOR WILL NOT TURN THE LASER OFF AFTER
THE TOOL HAS GONE OUT OF LEVEL.
The Bump Sensor is NOT AN OUT OF LEVEL SENSOR. See "Bump
Sensor" section.
THE ROTATING LASER BEAM IS DIFFICULT TO SEE INDOORS.
Ambient light conditions will influence the visibility of the laser beam.
To aid in beam visibility, adjust the rotation speed using the ON/OFF
VARIABLE SPEED SWITCH. Remember: Slow Speed = Bright Line;
Fast Speed = Solid Line. Wearing the Laser Enhancement Glasses
can also help you see the beam better.
I NEED TO ADJUST THE LASER FOR A VERTICAL / PLUMB
ORIENTATION.
See "Mounting on a Tripod," "Floor Mount" and "Wall Mount" sections.
I NEED TO ADJUST THE LASER FOR MOUNTING ON A WALL.
See "Wall Mount" section.
THE LASER ROCKS WHEN POSITIONED ON THE FLOOR.
The laser is designed to sit on 3 built in contact points. If the laser
rocks, try placing it on a more level surface or on a a tripod.
I NEED TO STOP THE ROTARY HEAD ROTATION TO DIRECT
THE LASER DOT ONTO A MARK OR TO SET A MARK.
See "Manual Head Rotation" section.
THE BUBBLE(S) IN THE VIAL(S) WILL NOT MOVE WHEN
ATTEMPTING TO LEVEL THE LASER.
The tool must be positioned on a relatively smooth and level surface
before being leveled. The laser cannot be leveled if the tool is set up
outside of its leveling range. Roughly level the tool before attempting
to level the laser with the leveling knobs.
I CAN ONLY ADJUST THE BUBBLE IN THE PLUMB VIAL WHEN
ATTEMPTING TO PROJECT A VERTICAL LASER LINE.
See "Vertical Plumbing" section for instructions on projecting a vertical
laser line.
