Congratulations on your choice of this Manual-Leveling Rotary Laser.
We suggest you read this instruction manual thoroughly before using
the instrument. Save this instruction manual for future use.
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.
Position the two slots on the laser into the base, tighten the locking
knob to secure the base to the laser. The laser can now be
secured to a tripod.
Battery Installation
1. Disconnect the laser from the base as shown in the figure on the
next page (rotate the base unlock/lock knob counterclockwise to
unlock the laser from the base).
2. Remove battery cover (rotate the battery compartment knob counterclockwise to the open position).
3. Put in 4 “AA” alkaline batteries following the polarity specified in
the battery compartment.
When first turning the detector on, the middle signal
indicator turns red first and then turns green. If the horn
gives two short sounds and the unit powers off
automatically, it means that the battery voltage is
seriously low and it is necessary to replace the battery
immediately. When turning the power on and the down
signal indicator flashes, it means that the battery is low
and it is necessary to replace the battery.
Power Key: Turn on/off the instrument
3. Battery Installation
1. Open the battery cover and put the batteries into the battery
case according to the polarity shown in the battery slot.
Note: Take the batteries out when the unit is not in use for a
long time.
4. Detecting Methods
1. This unit can detect a red rotating laser beam.
2. Press the Power Key once , the middle signal indicator will
quickly turn red first and then turns green. It will beep once
to indicate that the instrument is ON.
While detecting, the signal indicators show as follows:
The lower red
LED is on

The upper red
LED is on

Note:
1. While detecting a horizontal laser beam, it is necessary to
have the horizontal bubble vial centered, as the tilt of the
detector will influence its receiving accuracy.
2. Keep the detecting window facing the
rotating laser.
3. Keep the detector still while detecting the
laser beam
4. When the laser beam is centered, mark at
the front reference marker.
5. When the detector does not
receive a laser signal for 6
minutes, and there are no buttons
pushed during these 6 minutes,
the middle signal indicator will turn
green first and then turn red. The
horn will give two short sounds and the unit will power off
automatically.
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Checking for Accuracy:
Wall
Platform
1. Start by placing the laser 1’ away from a wall (near wall), and
at least 20’ from a wall (far wall).
2. Align the laser so that one axis (vial) points to both walls.
3. Turn the laser on and adjust the thumbscrews until the unit is
level in both the X and Y axis.
4. Make a mark where the laser hits the near wall (wall #1), and
then the same for the far wall (wall #2).
5. Next, move the laser to 1’ next to the far wall, and ensure it is
in the same axis.
6. Level the laser, and then adjust the height so that the laser is
level and hits the mark you made on the far wall (wall #2).
You may need to re-level to achieve this.
7. Then walk over to the original near wall (wall #1) and measure
the difference between the original mark and the laser line. If
the value is more than 1/4” at 100’, then calibration is required.
8. Ensure accuracy is verified for both the X and Y axis.
Note: X and Y axis are determined by the end user, either vial can be
considered X/Y.
Adjusting Accuracy:
1. Measure the difference between the original near wall mark
(wall #1) and where the laser is hitting the near wall.
2. Walk back to the far wall (wall #2) and adjust the laser so that
it is halfway between the two near wall marks (pencil mark
and laser mark).
3. Next, remove the screw cap for the vial for the axis you are
working with, and using a 2.5mm hex tool, adjust the vial so
that it appears level.
• This laser unit is a precision tool that must be handled with care.
• Avoid exposing unit to shock vibrations and extreme temperatures.
• Before moving or transporting the unit, make sure that the unit is turned off.
• Remove the batteries when storing the unit for an extended time (more than
three months) to avoid damage to the unit should the batteries deteriorate.
• Always store the unit in its case when not in use.
• Avoid getting the unit wet.
• Keep the laser unit dry and clean, especially the laser output window.
Remove any moisture or dirt with a soft, dry cloth.
• Do not use harsh chemicals, strong detergents or cleaning solvents to clean
the laser unit.
