OPERATION
• Protect the laser device against moisture and direct
sun light.
• Do not subject the laser device to extreme tempe-
ratures or variations in temperature. As an example,
do not leave it in vehicles for longer periods. In case of
large variations in temperature, allow the laser device to
adjust to the ambient temperature before putting it into
operation.
• Avoid heavy impact to or falling down of the laser
device. Damage to the laser device can impair its ac-
curacy. After heavy impact or shock, compare the laser
line with a known horizontal or vertical reference line.
1. Power switch
Push the power switch
up to turn the self-level-
ling cross-line laser level
on, and slide the power
switch down to turn the
tool off (fig 1).
2. To install or replace batteries (fig 2)
The battery compartment
holds two "AA" batteries.
1. Push the latch to open
the battery cover.
2. Insert two new "AA" al-
kaline batteries, following
the polarity (+/-) as indi-
cated on the pole plate.
3. Securely close the
cover.
NOTE:
• Always turn off the tool before installing or replacing
the batteries.
• Remove the batteries from the tool when not using it for
extended periods.
• The AA batteries should match each other in brand and
type.
• Do not mix old and new batteries.
• Remove depleted batteries immediately, and dispose
of them according to the laws and regulations governing
your community.
3. Laser line projection modes
Your self-levelling cross-line laser level has three laser-
projection modes. To select a specific laser-projection
mode, press the mode button until you reach the desired
projection mode. This laser tool defaults to the cross-hair
pattern mode when it is turned on.
To choose a projection mode, press the mode button:
OFF
ON

1. Press the button once
to select the cross-hair
pattern (horizontal and
vertical).
2. Press the button twice
to select the horizontal
laser line.
3. Press the button three
times to select the verti-
cal laser line.
4. Using your self-levelling cross-line laser level
Your self-levelling cross-line laser level has two working
modes: Self-levelling mode and Lock (manual) mode.
• Self-levelling mode
In this mode, the tool will level itself if it is within ± 4° of
horizontal.
1. Place the self-levelling cross-line laser level on a flat,
smooth surface that is within ± 4° of horizontal.
2. Turn the tool on by sliding the power switch to the up
position.
The self-levelling cross-line laser level will automatically
level within 5 seconds. The LED indicator will shine green.
3. Press the mode button until the desired laser-pro-
jection mode is achieved and the laser line is projected
from the laser aperture.
4. When the self-levelling cross-line laser out of level-
ling, the LED will turn to red and the laser line will blink.
5. To turn off the laser lines, slide the switch to the down
position.
WARNING!
When turning the laser on, always be aware of pro-
tecting your eyes and the eyes of those around you.
Never point the laser light at anyone's face, inclu-
ding your own.
• Lock mode
This mode cannot be used to perform horizontal or ver-
tical levelling, because the laser lines are no longer self-
balancing.
In this mode, the LED indicator will always shine red.
1. Keep the power switch off, press the mode button to
turn on the laser. The laser lines are now locked, and are
no longer self-levelling.
2. Press the mode button repeatedly to change the laser
projection mode.
3. Slope your self-levelling cross-line laser level to pro-
ject a straight line for reference. In this mode, the laser
lines are projected continuously and will not blink, even
if the slope angle exceeds 4°.
4. To turn the laser off, press the mode button repeatedly
until the laser shuts off.
5. Applications
Your self-levelling cross-line laser level can be hand-
held for point marking and simple alignment by sight,
or it can be used to make a "chalk line" using the lock
