DeWalt DW075 Instructions Manual page 33

NOTE: The laser will be easier to set up for wall
applications if the rotation speed is set to 0 rpms
and if the remote control is used to line up the laser
with control marks. The remote allows one person to
set up the laser.
CONSTRUCTION GRADE ROD (FIG. 6)
DANGER: NEVER attempt to
use a grade rod in a storm or near
overhanging electric wires. Death or
serious personal injury will occur.
The D WALT Grade Rod is marked with
E
measurement scales on both sides and is
constructed in telescoping sections. A spring-loaded
button actuates a lock to hold the grade rod at
various lengths.
The front of the grade rod has the measurement
scale starting at the bottom. Use this for measuring
from the ground up when grading or leveling jobs.
The back of the grade rod is designed to measure
the height of ceilings, joists, etc. Fully extend the top
section of the grade rod until the button locks into
the previous section. Extend that section either until
it locks into the adjacent section or until the grade
rod touches the ceiling or joist. The height is read
where the last extended section exits the previous
lower section, as shown in Figure 6.
OPERATION
WARNING: Always observe the safety
instructions and applicable regulations.
• To extend battery life, remove batteries when
the laser is not in use.
• To ensure the accuracy of your work, check
the laser calibration often. Refer to Field
Callibration Check under Laser Maintenance.
• Before attempting to use the laser, make sure
the tool is positioned on a relatively smooth,
secure surface.
• Always mark the center of the laser line or
dot. If you mark different parts of the beam at
different times you will introduce error into your
measurements.
• To increase working distance and accuracy, set
up the laser in the middle of your working area.
• When attaching to a tripod or wall, mount the
laser securely.
• When working indoors, a slow rotary head
speed will produce a visibly brighter line; a faster
rotary head speed will produce a visibly solid
line.
• To increase beam visibility, wear Laser
Enhancement Glass es and/or use a Laser
Target Card to help find the beam.
• Extreme temperature changes can cause
movement or shifting of building structures,
metal tripods, equipment, etc., which can effect
accuracy. Check your accuracy often while
working.
• When working with the D
Detector, set the laser's rotation speed to the
fastest setting.
• If the laser is dropped or suffers a sharp blow,
have the calibration system checked by a
qualified service centre before using the laser.
Laser Control Panel (fi g. 1)
The laser is controlled by the power button (e), the
speed/rotation button (h), the scan mode button
(i), and two arrows (j, k). The arrows control the
movement of the laser head left and right when the
laser is being used in the plumb mode.
TURNING THE LASER ON (FIG. 1)
1. Be sure that the batteries are properly installed
and the battery door is securely closed.
CAUTION: The laser will operate even
if battery door is not fully latched. To
secure the batteries, always ensure
battery door is closed and latched.
2. Gently press the power button (e) to power the
laser on. The power LED light (f) will illuminate
and the unit will self-level.
NOTE: The LED indicator is used to indicate power-
on (steady) and low battery (flashing).
NOTE: The head will begin or resume rotation once
the laser is level.
TURNING THE LASER OFF
Gently press the power button to turn the laser
off. The power LED indicator will no longer be
illuminated.
Laser Control Panel Buttons (fi g. 1)
POWER BUTTON
Press the power button (e) to power the unit on and
off.
ARROW BUTTONS
The arrow buttons (j, k) are used for different
functions depending on the operating mode of the
laser unit.
In Horizontal Mode:
The arrow buttons adjust the direction of the
laser beam in Scan Mode or Pointing Mode
(0 rpm).
In Vertical Mode:
The arrow buttons move the laser beam left
and right.
