LASER SAFETY
AVOID EXPOSURE: Laser radiation is emitted from this product. Use of controls,
adjustments or procedures other than those specified herein may result in laser radiation
exposure. Never stare directly at the beam or view directly with optical instruments.
This label is attached to the unit at the laser aperture.
IMPORTANT: “DANGER” labels are attached to every LCL4. They are not to be removed or
defaced.
Do not disassemble or attempt to perform any internal servicing. Doing so will void the
warranty. Repairs or service to this device are to be performed by authorized service
centres only. Do not aim the laser beam at people or
animals.
The LCL4 contains semiconductor laser diodes with
wavelengths of 635-650 nanometers. The total continuous
output of the beams never exceeds 4.99 milliwatts. The
LCL4 complies with US CDRH performance standards, 21
CFR, Sub chapter J and the regulations stipulated in EN60825-1/1994.
1. Open the battery cover
2. Place all three AA batteries into the battery compartment according
to the battery installation indicators displayed in the battery
compartment.
Note: Alkaline batteries offer the longest battery life when used in this
device. This device can not use rechargeable batteries.

OPERATION

Pendulum Lock
The LCL4 is a precision instrument and should be treated with
care. When not in use, the pendulum should always be in the off
position (figure1). Locking the pendulum allows the LCL4 to better
withstand vibrations and shock incurred during transportation or
if the unit is dropped.
Locked Line Angle
In the locked line angle position (Figure 2), the pendulum is
locked and will not automatically level or plumb the lines. When
in the locked line angle position, both the horizontal and vertical
beams will be on to allow angled lines. The green LED will blink
once per second.
Note: The unit will not change between Level Line Mode and
Plumb Line Mode while in the locked angle position.
Automatic Levelling
When the switch is in the pendulum unlock position (Figure 3) then the pendulum will
automatically level and plumb the horizontal and vertical lines, so long as the base is within
5º of true level. When the base is more than 5º out of level then the lines will flash once per
second accompanied by a warning beeping from the unit.
If the device is left out of level for more than 3 minutes then it will switch off. To reactivate
the unit, switch it off and then back on again.

OPERATION
Horizontal, Vertical, Plumb & Cross Line Options
The LCL4 has three line options, accessible by using the line options button located on
the top of the instrument. If the unit has been turned on, the plumb up and down beams
will always be on. Use the line option button to cycle through the level (horizontal), plumb
(vertical) or cross line modes, as shown below.
Auto-Off Feature
A battery saving Auto-Off feature has been incorporated into the LCL4. It will shut the device
off automatically after 60 minutes unless overridden. To disable the Auto-Off feature press
and hold the line options button when turning the unit on. The green LED will flash twice per
second to indicate the Auto-Off feature has been disabled.
Low Battery Indicator
When the battery charge becomes low, the red LED will flash twice per second. Note: the
LCL4 can be used for up to one hour during low battery indication before it will turn off
completely.
Pulse Mode
Pressing the pulse mode button, will place the unit into pulse mode so that it can work
with optional laser detector. Pressing the button again, returns to non-pulse mode. In pulse
mode, the Pulse Mode LED will be on.

multiple surfaces including wood, metal, pipes, construction tripods, camera tripods and flat
surfaces.
1/4” Tripod Mount
Use the threaded hole, located on the bottom of the universal mount, to mount the universal
mount and the attached LCL4 to a camera tripod.
5/8” Tripod Mount
Use this threaded hole, located on the bottom of the universal mount, to mount the
universal mount and the attached LCL4 to a surveyor’s tripod.
Screw / Nail Attachment Hole
Use the attachment hole to fasten the universal mount and the attached LCL4 to walls with
drywall screw of at least 2” (5cm) long.
Strap Raceways
Use the horizontal and vertical strap raceways to fasten the universal mount and the
attached LCL4 to objects such as pipes and wooden studs with a width of approximately
150mm (6”) or less
Magnets
Use the magnets, located on the back of the universal mount, to fasten the universal mount
and the attached LCL4 to objects such as steel studs. Use the magnets. Located on the
bottom of the mount, to mount the square, the universal mount and the attached LCL4 on
the floor.
