ATTENTION IMPORTANT
• Read all instructions prior to operating this laser tool. Do not remove any labels from tool.
• Do not stare directly at the laser beam.
• Do not project the laser beam directly into the eyes of others.
• Do not set up laser tool at eye level or operate the tool near a reflective surface as
the laser beam could be projected into your eyes or into the eyes of others.
• Do not place the laser tool in a manner that may cause someone to unintentionally
look into the laser beam. Serious eye injury may result.
• Do not operate the tool in explosive environments, i.e. in the presence of gases or
flammable liquids.
• Keep the laser tool out of the reach of children and other untrained persons.
• Do not attempt to view the laser beam through optical tools such as telescopes as
serious eye injury may result.
• Always turn the laser tool off when not in use or left unattended for a period of time.
• Remove the batteries when storing the tool for an extended time (more than 3 months)
to avoid damage to the tool should the batteries deteriorate.
• Do not attempt to repair or disassemble the laser tool. If unqualified persons attempt
to repair this tool, warranty will be void.

6. Operating Instructions
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
Battery Installation
Note: Always check to be sure that the on/off switch is in the off
position before removing and replacing batteries.
Usage for Rechargeable (40-6532 & 40-6539) & Alkaline Battery Cases
1. Put 4 “C” alkaline batteries into the battery case according to the
polarity indication shown in the battery case.
2. Put the battery case on the instrument and tighten the locking screw.
3. If using the rechargeable (40-6532 & 40-6539) battery pack, put
the battery box on the instrument and tighten the locking screw.

(e) Detecting Laser Level Signals
While detecting laser signals, the LCD will display as follows: (take
the set-up state of high sound and fine detection as an example)
When the laser signal is near the on-grade mark, the displayed up
and down arrows will decrease as the distance to the on-grade
mark decreases.
1. When detecting a horizontal laser signal, it is
important to have the bubble vial centered, as the
deflection of the receiver will influence its receiving
accuracy.
2. When detecting a vertical laser signal, it is
important to have the bubble vial centered, as the
deflection of the receiver will influence its receiving
accuracy.

(j) Detector Maintenance
• When you are done using the detector, return it to its packing case.
• Keep the detector, particularly the detecting window, clean. If unit
becomes dusty, use a clean cloth to gently wipe it clean.
• Avoid knocking the detector over or allowing it to fall on the
ground.
• Although the detector is rain resistant, you should avoid submerg-
ing the unit in water or other liquids. If detector comes into contact
with water or other liquids, wipe it dry immediately.
• Do not use the detector around fire or expose it to fire in any way.

3. Operation Guide
(a) Battery Installation
• Open the battery-box cap and connect the cords inside with the
two polarities of the 9V battery. Note: Take the battery out if
detector is not used for a long time.
• Put the 9V battery into the battery box and close the battery-box cap.
(b) Power on
• Press the on/off button. When power symbol is
displayed, the detector is ready for coarse detection.
• When low battery symbol is displayed, change the
battery.
• Press the on/off button again to turn off the detector.
(c) Rod Clamp
1. clamp bolt
2. screw
• Position the detector on the clamp holder using
the screw on the clamp holder.
• Position the clamp holder on rod using the clamp
bolt on the clamp holder.
(d) Detecting Laser Level Signals
1. Coarse detection
• Aim the receiving window at the rotating
laser. Loosen the clamp bolt and move the
detector up and down to receive the laser
signals transmitted by the rotating laser.
1625i-English_Manuals 12/28/16 9:41 AM Page 18

• When the detector displays like Fig. (A), move
the detector slightly downwards as indicated
by the arrow. When it displays like Fig. (B),
move it slightly upwards as indicated by the
arrow.
• When Fig. (C) is displayed, the detector is at the
right position.
• Tighten the clamp bolt and note the position
by the rabbet. This position will be the hori-
zontal reference in the coarse detection.
2. Fine detection
1. power symbol
2. fine detection symbol
• Press coarse/fine detection button. The detector
is ready for fine detection.
• Move the detector slightly up and down like the
coarse detection procedure.
• When the detector displays like Fig 6, it is at the
right position.
• Tighten the clamp bolt and note the position by
the rabbet. This position will be the horizontal refer-
ence in the fine detection.
(e) Volume Key
• If the detector is working in an area that makes it difficult to see the
display function, the sound function can be used instead.
• Press the sound function button. The sound symbol is displayed
which means it is ready for sound function. The detector then
sounds coarse/fine and on grade detection through sound (buzz)
signals.

• When the sound signal is a fast beep, move the instrument slightly
upwards.
• When the detector makes a short beep, move it slightly downwards.
• When the detector makes a continuous sound, it is on grade with
the laser beam.
• If there is no beep heard, the detector has not received the laser
signal.
(f) Automatic Shut-off Function
• The detector will automatically turn off if it has not received a laser
signal for 10 minutes.
(g) Detector Maintenance
• When you are done using the detector, return it to its packing case.
• Keep the detector, particularly the detecting window, clean. If unit
becomes dusty, use a clean cloth to gently wipe it clean.
• Avoid knocking the detector over or allowing it to fall on the
ground.
• Although the detector is rain resistant, you should avoid submerg-
ing the unit in water or other liquids. If detector comes into contact
with water or other liquids, wipe it dry immediately.
• Do not use the detector around fire or expose it to fire in any way.
