7. Using the Product
Power On/Off the Laser
Press the button to power on/off the laser. The rotating speed
will be set to high.
Power LED: Lighted LED indicates power is on.
Extinguished LED indicates power is off.
Flashing LED indicates low batteries – if flashing,
please change the batteries.
Change Rotating Speed
Press the button to change the rotating speed from high (600
rpm), to medium (400 rpm) and to low (200 rpm). When changing
the rotating speed, the corresponding LED will illuminate.

Manual vs. Self-leveling Operation
1. Turn the lock knob counter-clockwise to the “Off” position to lock
the compensator. The laser will be operating in manual mode and
will not be self-leveling.
2. Turn the lock knob clockwise to the “On” position to unlock the
compensator and allow the laser to self-level.
3. Place the laser on a relatively smooth, flat and level surface.
4. Set the lock knob to the “On” position.
5. Press the button to power on the laser.
6. Laser must be within ±3º of level for the self-leveling feature to
function properly. If the laser is tilted to exceed its self-leveling
range, it will stop rotating and will sound an intermittent beeping
sound.
Leveling the Laser for use in Vertical Mode
(Bubble Level Adjustment)
1. Turn the lock knob counter-clockwise to the
“Off” position to lock the compensator. The
laser will be operating in manual mode and will
not be self-leveling.

2. While holding the laser by the hand grips, insert the horizontal vial
adjustment knob into the adjustment knob receiver.
3. ently press the leveling base connecting bar
receiver into the laser’s connecting bar until
the clip spring is activated.
4. Place the leveling base with attached laser on a
relatively smooth, flat and level surface.
5. Turn the adjustment knob to center
the bubble in the vial.
Bubble Centered
Notes:
• While the laser is in the horizontal status (manual mode), set the
lock knob to the “Off” position.
• After operating or before moving the unit, always power off the
laser and set the lock knob to the “Off” position. This ensures no
damage can happen to the laser assembly during transport.
• If you plan to store the laser for more than 3 months, remove
batteries from the laser and detector.

(b) Display
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
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 soon.
Power Key: Turn on/off the instrument

4. De ec ing Me hods
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:
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.

reference marker.
5. When the detector does not receive a
laser signal for 6 minutes, and there are
no buttons pushed during these 6 min-
utes, 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 auto-
matically.

6. Main enance
• Keep the detector, particularly the detecting window, clean. If unit
becomes dusty, use a clean cloth to gently wipe it clean.
• Avoid knocking the unit over or allowing it to fall on the ground.
• Although the detector is rain resistant, you should avoid
submerging the unit in water or other liquids. If unit comes into
contact with water or other liquids, wipe it dry immediately.
• Do not use unit around fire or expose it to fire in any way.

9. Application Demonstrations
The 40-6519 can be used for many applications. Some ideas to
enhance the utility of your new laser include:
• Installing wood or metal stud walls. Use horizontally to mark
reference heights on the stud walls for electrical outlets or other
items. Use vertically to set plumb, or to layout the location of the
wall’s bottom plate.
• Use to lay out tile. The laser can be used both horizontally or
vertically to align wall and floor tile in all directions.
• Use the laser vertically to align the ends of shelving, cabinets, or
stacked photos.
• User the laser horizontally to level shelving, level cabinets, or level
and align rows of photos.
• Use the laser to align tape for pinstriping or other marking
of walls.
• Use the laser outdoors with a detector to grade an area, build
retaining walls (horizontal and vertical mode), layout fencing or
posts level (horizontal mode) or straight (vertical mode).
• Use to install drop ceilings
