Congratulations on your choice of this Electronic Self-Leveling Dual Grade
Horizontal / Vertical Rotary Laser. We suggest you read this instruction
manual thoroughly before using the instrument. Save this instruction manual
for future use.
This tool emits one rotating laser beam plus one plumb beam and is ideal for
laying out indoor or outdoor construction projects.
This is a Class IIIa laser tool and is manufactured to comply with CFR 21, parts
1040.10 and 1040.11 as well as international safety rule IEC 285.
• Large electronic self-level range: When beyond the ±8°
leveling range, the laser beam will flash, laser stops rotating
and an audible alarm activates.
• Vertical and horizontal working modes: Electronic self-leveling
in both horizontal and vertical mode with one rotating laser
beam and one 90° split beam.
• Three rotational speeds: 300, 600 and 1100 RPM
• Scan function adjusts the scan line size and scan direction.
• Out-of-level alarm ensures the working accuracy.
• Fine self-calibration function.
• In “Tilt Mode” the laser will stop rotating and flash when
bumped to ensure work accuracy.
• Programmable dual slope function allows the user to perform
slope in both X & Y axis.
Please read and understand all of the following instructions, prior
to using this tool. Failure to do so, may void the warranty.

Alkaline Battery Installation:
Put 3 “D” alkaline batteries (not included)
into the battery pack according to the polarity
direction, then insert the battery pack into the
laser. (Note: Batteries facing up.)
Rechargeable Battery Pack Installation:
Install the rechargeable battery pack into
the laser.
Charging the Rechargeable Battery Pack:
Charge the rechargeable battery pack by inserting the charger into
the charging port. The LED on the charger is red during the charging
process; the LED on the charger will turn green when the battery is
fully charged.
(1) Charge the rechargeable battery when the battery power is
low (battery symbol on the LCD is flashing). This will extend
the battery life.
(2) If the laser is not going to be used for a long period of time,
charge the rechargeable battery every 2-3 months.
Use of the Vertical Bracket and Fine Adjusting Plate:
Screw the vertical bracket onto the side of
the laser with the vertical bracket leveling
knobs at the bottom of the laser and the
circular vial at the top of the laser.
Vertical Bracket
For exact positioning of the X or
Y-axis, screw the Fine Adjusting
Plate on the tripod and then screw
Fine Adjusting Plate
the laser to the Fine Adjusting Plate.
Using the Sighting Scope, rotate
the laser to the exact position required. Use the Fine Adjusting
Knobs for fine movement. Use the Lock Knob when positioned in
the correct position.
