GENERAL SAFETY RULES FOR OPERATION
WARNING
Read all safety warnings, instructions, illustrations and specications
provided with this laser level. Failure to follow all instructions listed below
may result in personal injury.
Save all warnings and instructions for future reference.
•Do not stare into beam regardless of distance.
•Do not use the laser intensive glasses as safety goggles, sunglasses or when driving.
•Do not point laser in the direction of other people or animals.
•Do not point laser in the direction of mirrors or other reective surfaces.
•Store in a secure location when not in use.
•This is a quality laser measuring device and is 100% factory adjusted within the stated
tolerance.
•Laser should not be used as a toy or by children.
•Do not view beam through optical instruments such as theodolites, binoculars, cameras or
magnifying lenses.
•Avoid using laser in darkened areas. Ensure sucient light levels to avoid damage to eyes.
•Set up cross line laser to ensure laser beam path is above or below eye level.
•Ensure cross line laser is securely set up to avoid accidental movement.
•Always ensure the laser beam is aimed at a sturdy work piece without reective surface.
Bright shiny reective sheet steel or the like is not suitable for laser use as the reective
surface could direct the beam back at the operator.
•Do not break up or throw the battery into re, please recycle the battery after use.
•Turn the laser o when it is not in use. Leaving the laser on increases the risk of staring into
the laser beam.
•Do not use or store the instrument in locations where the temperature may reach or
exceed 40°C.
•Do not disassemble the instrument or attempt to perform any internal servicing as this will
void your warranty. Not user serviceable parts included. Only approved and authorised
service technicians can carry out warranty repairs.
•Avoid direct eye exposure. Consult your laser safety ocer or IEC 60825.14:2011 Part 14 for
best operating practice.
CAUTION Class 2 laser product according to IEC 60825-1:2014.
Do not stare into the laser beam or direct it towards other people.

OPERATION INSTRUCTION
BATTERY PLACEMENT
•Your laser level requires 3 AA batteries. Use only new, high-quality battery for best results.
•Locate battery compartment at the bottom of the laser. Insert batteries according to the
symbols and polarity.
•When the battery voltage is low, the indicator light will start ashing in which the batteries
must be replaced.
ON/OFF
WARNING Always turn o all lasers and latch the pendulum in place before
transporting.
•Press and hold“LINE” button to turn on the laser.
•Alternatively, turn the laser on by sliding the power switch to ON position. Pendulum is
automatically released for self levelling.
•To turn the laser o, place it on a stable at surface. Slide the power switch to OFF position.
Pendulum is automatically locked when the switch is turned to OFF position.
LASER LINES SELECTION
•Turn the switch to ON position. All lines appear when the laser is turned on.
•Press“LINE” button to select laser lines.
AUTOMATIC SELF-LEVELLING
•Pendulum lock (power switch to ON position) must be released for horizontal and vertical
levelling.
•Turn on the laser level. The pendulum automatically aligns a position within the range
of self-levelling range ±3.5°. Within this range, the laser level automatically correct its
position.
•Laser beams start to blink when the device is out of self-alignment range of ±3.5°. In this
case, place the laser level on a at surface, adjust tripod or wall mount until blinking stops.
PULSE MODE
•Press to activate Pulse Mode so that the device can work with optional laser detector.
•Laser lights will pulse with high frequency, making the laser lines slightly darker.
•Pulse Mode LED Indicator light will be on when this is activated. Press the button again to
exit pulse mode.
WARNING
This is a high precision instrument - To avoid damage always transport
instrument and store with pendulum lock on (or power switch to OFF
position) and in its protective case.

CALIBRATION CHECK
It’s possible for you to check the calibration of the laser. Calibration by yourself is only
approximate and the accuracy of the calibration will depend on the care with which you
proceed.
TO CHECK THE LEVEL
Checking the horizontal pitch calibration of the laser requires 2 walls, which must be at least 5
metres apart. The best calibration results can be achieved if the laser is mounted on a tripod.
1. Mark point A1 on the wall.
2. Turn the device 180 ° and mark A2 on the opposite side of A1. You now have a horizontal
reference between point A1 and A2.
3. Position the device as near as possible to the wall at the same height of point A1.
4. Turn the device 180° and mark point A3. The dierence between point A2 and A3 is the
tolerance.
1.
1.
If the distance between A2 and A3 is more than 2mm/10m, the device is in need of calibration.
Contact authorised dealer or service agent.
CHECKING THE VERTICAL LINE
1. Position the device about 5 m from a wall. Fix a plumb bob with a line of 2.5 m length on
the wall, making sure that the bob can swing freely.
2. Switch on the device and align the vertical laser to the plumb line. The precision is within
the specied tolerance if the deviation between the laser line and the plumb line is not
greater than ± 2mm.
7OPERATING MANUAL
CHECKING THE HORIZONTAL LINE
1. Position the device about 5 m from a wall
and switch on the cross laser. Mark point B
on the wall.
2. Turn the laser cross approx. 2.5 m to the
right and mark point C.
3. Check whether the horizontal line from
point C is level with point B to within ± 2 mm.
MAINTENANCE AND SERVICE
•Do not attempt to open the device. To ensure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment should be performed by authorized service centres.
Contact your dealer for more details.
•Do not drop, knock or shake the laser level as this will aect precision.
•Remove batteries when the device is not in use.
•Keep the laser level clean at all times. Use a soft lint-free cloth for the body and lens tissue
for glass windows. Do not use abrasive cleaners or solvents.
•Don’t expose the laser level to high temperatures or humidity.
•Do not store the laser level in hot areas, hot temperatures can short the life of electronic
device, damage battery, and warp or melt certain plastics
•Do not store the laser level in cold areas. When the unit warms up to its normal operating
temperature, moisture can form inside where it may damage circuit board.
•Avoid shock, vibrations and extreme heat.
•Do not immerse the instrument in water.
•Always slide the power switch to the OFF position when storing, transporting or moving
around the job site.
•Calibration service is recommended at least once a year or as needed.
TROUBLESHOOTING
ISSUE POSSIBLE CAUSE AND SOLUTIONS
