Laser Safety
• Use the tool only with the
specifically designated batteries.
• Store the tool out of reach of children and
other untrained persons. Laser tools are
dangerous in the hands of untrained users.
• Use only accessories that are
recommended for your model.
• Tool service must be performed only by
qualified repair personnel. Repairs, service
or maintenance performed by unqualified
personnel will void the warranty.
Only approved and authorised service
technicians can carry out warranty repairs.
• Do not use optical tools such as a telescope
or transit to view the laser beam. Serious
eye injury could result.
• Do not place the tool in a position which
may cause anyone to intentionally or
unintentionally stare into the laser beam.
Serious eye injury could result.
• Do not position the tool near a reflective
surface which may reflect the laser beam
toward anyone’s eyes. Serious eye injury
could result.
• Do not set up the tool at a position where
the laser beam can cross any person at
head height.
• Do not let children come in contact with
the tool.
• Turn the tool off when it is not in use.
Leaving the tool on increases the risk of
staring into the laser beam.
• Do not operate the tool around children or
allow children to operate the tool. Serious
eye injury may result.
• Position the tool securely on a level
surface. Damage to the laser or serious
injury could result if the laser falls.
• Do not remove or deface warning labels.
• Never look into the laser beam directly
and intentionally.
• Do not use optical tools to view the
laser beam.
• Do not set up the tool at a position
where the laser beam can cross any
person at head height.
• Do not let children come in contact
with the laser.
Read the following safety instructions before attempting to operate this tool.
Keep these instructions in a safe place or store in the carry pouch for future reference.
There are no user serviceable parts inside.
Disassembling the tool will void all
warranties on the product. Do not modify
the tool in any way. Modifying the tool may
result in hazardous laser radiation exposure.

POWER SUPPLY
Rechargeable battery pack
• The laser level is supplied with a rechargeable
Ni-MH battery pack that is located in the base of
the laser level.
• The rechargeable battery pack is supplied only
partially charged. Charge the rechargeable battery
pack before use. Keep the rechargeable battery
pack in the carry case when not in the laser level.
• The power indicator light will flash when the
battery is low. The laser level should be re-charged
as soon as possible.
• Battery pack capacity decreases at low
temperatures; a depleted pack may not function
when cold.
Indoor charger
• The indoor charger is for indoor use only.
• Do not store in locations where moisture can be
present or where the chargers could be exposed to
extreme temperatures.

Charging the rechargeable battery pack
• Insert the charger into one of the two charging
ports. The charging ports are located underneath
the control panel (Fig.1) and on the battery pack.
Progress will be shown by the power indicator
display on the charger as following:
Red (flashing) = Charger and battery are not
connected.
Red (constant) = Battery is charging
Green (constant) = Battery is charged
• Charging time is approximately 5 hours for a
depleted battery.
The battery pack does not need to be inserted
in the laser level whilst charging via the port
on the battery pack.
Removing and inserting the rechargeable
battery pack
• Loosen the battery thumb screw on the base of the
laser level and remove the battery pack.
• Insert the battery pack,ensuring the metal pins are
aligned. Tighten the battery thumb screw.
WARNING! Do not attempt to
disassemble the battery pack.
HORIZONTAL MEASUREMENT SETUP

OPERATION
Powering on
• Press the power button once and the laser level will
power on and begin automatically self-levelling.
When this levelling process is complete, the penta
prism inside the lighthouse will start rotating.
• If the laser level is outside the self levelling range
the laser level will not level causing the laser beam
to flash continuously.If this occurs, reposition the
laser level onto a level surface until the laser level
can level off.
In bright outdoor conditions, visible distance
will be significantly reduced. For outdoor use,
it is recommended to use the included detector.
Powering off
• Press the power button once and the laser level
will power off.
Speed control
• Press the speed control button on the remote
control to cycle through various rotational speeds.
Sleep mode
• Press the sleep button on the remote control to
enter into sleep mode.
• The laser diode will stop spinning and shut off. (The
unit is not turned off in sleep mode).
• Press the sleep button on the remote control to
exit sleep mode.
After 60 minutes of inactivity during sleep
mode, the laser level will turn off automatically.
Tilt alarm
• Once the laser level has been levelled off the tilt
alarm can be enabled by pressing the tilt alarm
button.The tilt alarm indicator light will flash
continuously whilst active.
• If the laser level is disturbed while the alarm is
active the laser level will stop rotating and will
need to be powered off and on again to reset to a
level position.
Setting up a manual grade / slope
• To create a manual grade / slope, press the manual
grade mode button on the laser level control panel
or remote control.The laser level will now be in
manual mode with the X-axis active.The LED X / Y
axis indicator on the laser control panel will display
a solid light to indicate X-axis is selected.
• Press the grade adjustment arrow buttons on the
remote control.
• To change to the Y-axis, press the manual grade
mode button.The LED X / Y axis indicator on the
laser control panel will flash to indicate the Y-axis
is selected. The laser level can now be adjusted
on the Y-axis.
• Press the grade adjustment arrow buttons on the
remote control.
• To adjust the grade, press the manual grade mode
button to cycle between X andY axis
• To cancel manual grade mode, and return to
normal levelling press the power button off and on
again to reset the levelling process.
When in manual mode the laser level will
not self level and correct for vibrations and/or
disturbances.
Grade adjustments can only be made by
pressing the grade adjustment arrow buttons
on the remote control.

Care & Maintenance
Calibration Check
1. This is a precision measuring tool and should
always be handled with care and transported
within the carry case provided.
2. Always turn the tool off when transporting the
laser level or moving around the job site.
3. Whenever possible, store the tool in a dry, shady
location.
4. When the tool is not in use or is being stored, it is
highly recommended to remove the batteries.
5. Calibration of the tool is recommended: every six
months, if ongoing accurate levelling is required,
or an impact has occurred.
6. The operator should check the accuracy of the tool
before precision levelling is attempted. Failure to
do so may result in inaccurate measurements.
7. Clean the tool with a dry, soft cloth after use in
dusty,damp or wet conditions before storing.
8. Smudges and fingerprints may be removed with a
damp tissue or a soft, lint-free cloth.
Mounting to a Construction Tripod
A construction tripod (flat, domed or
elevating) can be purchased from your
nearest measurement tool dealer. The
below instructions are generic only and
set-up methods may vary between models.
Refer to the documentation from the tripod
manufacturer for details.
• Extend the tripod legs to the required height and
ensure the legs are spread wide enough so that
the tripod platform is stable. Secure the legs in
place (refer to the documentation from the tripod
manufacturer for details).
• Place the laser level onto the tripod with the
lighthouse facing upwards and mount the male
5/8” thread into the base until firm. Do not over
tighten as this may cause damage to the laser
level or tripod.
• If using an elevating tripod with a measuring scale
on the centre column, the height can be adjusted
as required.
WARNING! Attaching the laser level to
a tripod without the correct thread size
may cause damage.
!
NOT INCLUDED
Before doing any precision levelling it is advised to
check the calibration of the laser level.
• Set up the laser level on a tripod at about 30m
facing a wall or staff with a detector.
• Allow the laser to level.
• Detect and note laser position on the wall or staff.
• Without moving the tripod, rotate the laser level
180°.
• Detect and note laser position on the wall or staff.
• Calculate the distance between the two readings.
• The difference should be within 6mm at 30m.
• If the laser level is out of calibration it is advised to
send it to an authorised service centre.
