OPERATION
The tool is intended for determining level and plumb
alignment, and checking horizontal and vertical reference
lines.
The tool is designed for indoor use only.
Extreme temperature changes can reduce the
accuracy of the laser. Allow the tool to adjust to the
ambient temperature of the work environment before
using. Do not subject the laser to extremely cold or hot
environments.
Make reference marks at the center of the laser line.
Turn the tool off when not in use.
SELF-LEVEL LOCk
The tool has a self-leveling function that automatically
levels the laser lines within 5 seconds if the tool is within
±4° of horizontal.
To active the self-leveling function, slide the Self-Level
Lock (1) all the way up to "ON" position. It actives the
laser simultaneously. Two crossed laser lines will appear
on the work surface.
The Leveling Indicator (3) on the top of the tool indicates
the status of the self-leveling function. A green light
indicates the laser line is self-levelled. A red light indicates
the laser line is not self-levelled.
To deactivate the self-leveling function, slide the Self-
Level Lock down to "OFF" position. It will turn the tool off.
POWER / MODE SELECTOR BUTTOn
The Power/Mode Selector Button (2) is located on the top
of the tool.
The tool has three laser line patterns: Crossed, Horizontal
and Vertical. The laser line pattern can be selected when
either self-leveling is ON or OFF.
When the Self-Level Lock is ON, the laser has been already
activated. The Power/Mode Selector Button is for selecting
the laser line pattern only. Press the Power/Mode Selector
button repeatedly to choose the desired laser line pattern.
When the Self-Level Lock is OFF, the tool can be turned on
by pressing the Power/Mode Selector Button. Repeatedly
press the button to select the laser line pattern or turn
the tool off.
SELF-LEVELInG MODE
To Set the Tool in Self-Leveling Mode:
1. Place the tool on a flat and solid support or on a tripod.
2. Slide the Self-Level Lock "ON" to activate the self-
leveling function. Two crossed laser lines will appear on
the work surface.
3. Check the Leveling Indicator. If it is green, the self-
leveling function is at work. If it is red and the laser
lines are flashing, the tool is outside of the ±4° self-
leveling range and will require adjusting until the
indicator appears green.
nOn-SELF-LEVELInG MODE
The Non-Self-Leveling Mode is for alignment purposes
and for projecting reference laser lines. It cannot be used
to perform leveling functions. In this mode, the Leveling
indicator (3) always appears red.
To Set the Tool in Non-Self-Leveling Mode:
1. Place the Self-Level Lock in the "OFF" positon.
2. Press the Power/Mode Selector Button (2) to turn
the tool on. The initial laser projection is two crossed
laser lines. You may select other laser line pattern by
pressing the Power/Mode Selection Button repeatedly.
3. Rotate the tool until the desired laser reference line is
projected on the work surface.
USInG THE ADJUSTABLE BASE
The tool kit comes with an Adjustable Base (6). It has a
Base Foot (7) for placing on a flat surface, a 1/4" female
threaded screw insert on the bottom for attaching on a
tripod, and a Wall Key (10) and Magnets (9) on the back for
mounting on a wall. The Adjustable Base is able to adjust
the height within a 3" range.
