- The beam can be set to scan in 0°, 15°, 45° or 90°
degree mode using button

.
Laser Control Panel Buttons (Fig, B, R)
Power Button
To completely power the laser unit off, the power button on
the control panel of the laser unit must be pressed for 3 sec.
The laser unit will also automatically power off if it is left in
Sleep Mode for 8 hours.
NOTE: Press the remote control power button to put the laser
unit into Sleep Mode. In Sleep Mode all laser unit functions
shut off except for a periodic blink from the power LED on the
control panel of the laser unit. Press the remote control power
button again to “wake up” the laser unit.
Speed/Rotation Button
The speed button
3
is used to adjust the rotation speed of the
laser beam through its 4 preset speeds.
The head speed will cycle through 4 speeds, then repeat the
sequence as the speed/rotation button is pressed.
NOTE: The speed/rotation button performs the same function
as the speed/rotation button on the remote control.
Scan Mode Button
15˚/45˚/90˚
The scan mode button
4
is used to make the laser head sweep
back and forth, creating a short, bright laser line. This short line
is much brighter and more visible than when the unit is in full
rotation mode.
Using Scan Mode:
• To enter Scan Mode, push and release the scan mode
button
4
. To cycle through the scan angles, continue to
press the button until you reach the angle desired. Repeat
the sequence to change angles.
• The direction of the scan zone can be controlled with the
arrow buttons (
6
,
7
) on the laser unit control panel or the
remotecontrol.
Slope Mode Button
• To activate Slope Mode press the laser keypad slope
modebutton
2
.
• To return to self leveling mode and re-engage full self-
leveling, press and hold the mode button
2
again.
Setting the Slope Direction
When Slope Mode is activated, the unit automatically engages
the X- Axis. This allows the operator to slope the laser in the
direction of the X-Axis, as indicated by the “gunsights” on
therollcage.
The LED indicator light on the laser unit control panel (Fig. B,
11
,
12
) will indicate the slope direction that is selected. The
selected axis is identified by LED lights
24
,
25
.
DW079LR/LG only: In certain situations, it may be desirable to
slope the laser in the Y-axis. The direction of Slope Mode can be
changed back and forth between the Y- and X-axes by pressing
the X-Y axis button
5
on the keypad.
Setting the Amount of Slope
Once Slope Mode is activated and the desired axis is active the
amount of slope can be adjusted as follows:
• Use the laser control panel up and down arrow buttons
(Fig. B,
6
,
7
) to tilt the laser rotor head up and down.
Arrow Buttons (Fig. R)
The arrow buttons (
6
,
7
) are used for different functions
depending on the operating mode of the laser unit.
In Self-Leveling Horizontal Mode: the arrows buttons adjust
the direction of the laser beam clockwise or counter clockwise
during rotation or Scan Mode.
In Self-Leveling Vertical Mode: the arrow buttons move the
laser beam left and right.
In Slope Mode: the arrow buttons are used to tilt the
laserhead.
Height of Instrument Alert
The DW074LR and DW079LR/LG have a built-in alarm feature
that alerts the operator if the unit is disturbed after the unit has
self-leveled. The laser unit will stop rotating, the control panel
LED indicator light will flash and the beeper will sound.
Turning the Laser Off
Press the the power button for 3 sec to turn the laser off. The
power LED indicator light will no longer be illuminated.
To Reset The Laser Unit for Continued Use
• Turn the unit off and back on again using the power button
on the laser unit control panel.
NOTE: Always recheck the laser setup after the Height of
Instrument Alert (Hi mode) has triggered.
Using the Laser on a Tripod (Fig. C)
1. Position the tripod securely and set it to the desired height.
2. Make sure that the top of the tripod is roughly level. The
laser will self-level only if the top of the tripod is within ± 5˚
of level. If the laser is set up too far out of level, it will beep
when it reaches the limit of its leveling range. No damage
will be done to the laser, but it will not operate in an “out of
level” condition.
3. Secure the laser to the tripod by attaching the tripod
adapter
20
as shown in Figure C to the laser body. The
adapter may be assembled to the bottom for level mode
or to the side for plumb mode. Place the assembly on the
tripod and screw the threaded knob on the tripod into the
female thread on the tripod adapter.
NOTE: Be sure that the tripod you are working with has a
5/8"–11 threaded screw to ensure secure mounting.
4. Turn the laser on and adjust the rotation speed and controls
as desired.
Using the Laser on a Floor (Fig.D)
The laser level can be positioned directly on the floor for
leveling and plumbing applications such as framing walls.
1. Place the laser on a relatively smooth and level surface
where it will not be disturbed.
