OPERATION
To Install/Replace Batteries (Fig. 3)
This Auto Leveling Laser level uses three “AA” alkaline batteries.
1. Push the hook as the arrow to take away the battery cover.
2. Insert three new “AA” alkaline batteries, following the polarity (+/-) as indicated on the
inside of the battery compartment.
3. Replace the battery cover and lock it in place.
CAUTION: Always turn the level off before installing or replacing the batteries.
NOTE:
• Replace the batteries when the LED indicator blinks in red. The laser will be shut off

7
in one hour approximately from the
LED indicator starts to blink. Shutting
off the laser line not used can extent
the battery life.
• Remove the batteries when the tool
is not used for a period of time.
• Do not mix old and new batteries.
• The 3 AA batteries should match
each other in brand and type.
• Remove depleted batteries
immediately, and dispose of them
according to your local ordinance.
Never dispose of batteries in fire.
Turn ON/OFF the Auto Leveling Laser
Level (Fig. 4)
1. Push the ON/OFF switch to the “ON”
position” to turn on the laser. The Auto
Leveling Laser Level defaults to turn
on all the lasers. The LED indicator of
indoor measurement will be lit at the
same time.
2. Push the ON/OFF switch to the “OFF”
position to shut off the laser. The
pendulum will be locked to protect the
accuracy.
Laser Line Projection Modes
The Auto-Leveling Laser Level has
six laser projection modes. To select
a specific laser projection mode, press the Mode button until you reach the desired
projection mode. This laser level defaults to turn on all the lasers when it is switched on.

To choose a projection mode, press the Mode button:
1. Once to select the front horizontal and vertical laser lines.
2. Two times to select the front horizontal laser line.
3. Three times to select the front vertical laser line.
4. Four times to select the front vertical line, side vertical line and lower laser dot. The
two vertical lines are crossed on the ceiling.
5. Five times to select lock mode, all the laser will be turned on.
6. Six times to return to the default mode.
NOTE:
• In the lock mode, the lasers are projected continuously even if the slope angle
exceeds 4°; The LED indicator lights in red. This mode can not be used to perform
horizontal or vertical leveling, because the laser lines/dot are no longer self-
balancing.
• In the other modes, LED lights in green when the tool is self leveled. When the tool
is out of working range, the laser lines will blink and the LED indicator will light in
red. Adjust the tool to level approximately to recover self leveling.
• Choose the proper projection mode in your actual working. Shutting off the laser line
not used can extend the battery life.
Indoor and Outdoor measurements
The indoor measurement mode is used for short distance measurement under normal
room brightness, e.g. indoors. But when it works outdoors, the strong sunlight will make
the laser lines hard to identify. Now switch to the outdoor measurement mode, the
laser lines will project in pulse, by the laser receiver (sold separately), the laser can be
detected up to 40m away.
When the laser level is turned on, it defaults to indoor measurement mode. Press the
Indoor/outdoor measurement button to switch to outdoor measurement mode, the LED
indicator of outdoor measurement will be lit on.
NOTE:
When switch to outdoor measurement mode, the laser will project in pulse instead

9
of continuous signals, so the brightness of the
laser lines seems a little darker than in the indoor
measurement mode in visual. It has no affection
to the measurement, in outdoor measurement
the tool should be used with laser receiver (not
included).
Mounting to a Tripod (only available in tripod
version)
This Auto Leveling Laser Level can be mounted
on a general 1/4” tripod directly (sold separately).
By the tripod the tool can easily be adjusted to a
proper height and orientation.
By the attached conversion adapter, the tool can
also be mounted on a 5/8” tripod and allow the
laser dot go through the tripod pole and projected
on the floor.
1. Align the 5/8” thread hole in the adapter with the
5/8” tripod and mount the adapter to the tripod
(Fig. 5).
2. Move the tool back and forth on the adapter,
make sure the laser aperture located on the
bottom of the tool is aligned with the 5/8” thread
hole of the adapter, and connect the tool with
the adapter with the 1/4” knob of the adapter
(Fig. 6).
3. Turn on the laser; slowly adjust the tool on the
adapter to let the laser dot just go through the
tripod pole and project on the floor. Lock the tool
with the adapter by tightening the 1/4” knob in
position (Fig. 7).
