Operation Manual
To help you use this instrument quickly, we provide a
specific operation manual for you. Please read the
manual carefully before you use the instrument, and
keep it well.
Thanks for choosing and purchasing Laser Marker, the
precise instrument. To assure the requirement of precision, please carefully read the manual before you use the
instrument, properly keep this instrument for future
reference.

Compact, light-weighted, easy to carry and operate,
with accurate marking capacity.
Magnetic damping compensator ensures quick
automatic leveling.
Transmit one level laser beam and one perpendicu-
lar laser beam with intersecting as a 90 degrees right
angle cross curve, and the perpendicular laser beam
can be extended to exceeding the roof.
In case of exceeding leveling scope, laser beam of
the instrument will automatically flash to give
alarm.

Perpendicular laser beam transmitting window
Open the battery case to insert two sets of 1.5V AA
alkaline batteries.(Note the polarity)
Properly install the level rotator of the instrument
and put it on the elevating tripod support. Properly
adjust the leveling.
Turn the power and the instrument will be on the
automatic leveling condition.
Turn the switch button(V/H), level and perpendicular laser beam will be transmitted.
In case the laser beam flashes to give alarm, it
indicates that the instrument isn’t smoothly
positioned and exceeds automatic leveling scope. It
is necessary to re-position the instrument and adjust
the elevating tripod or leg screws till the water
bubble go into the circle.
Change the batteries in case the power isn’t
sufficient.

The compact instrument Laser Marker is light-weighted,
easy to carry and operate, with accurate marking
capacity. It is widely applicable to construction and
inspection of interior decoration, building installation,
piping wiring and various fields requiring marking and
positioning.
The laser radiation is strong. Do not look at laser beam
directly, avoiding hurting your eyes.

i. Self-check of level accuracy
Find a smooth wall surface without vibration,
which shall be little affected by wind. Mount this
instrument five meters away from the wall surface.
Properly install the level rotator of the instrument
and put it on the elevating tripod support. Properly
adjust the leveling.
Turn the power and the instrument will be on the
automatic leveling condition.
Turn the switch button(V/H) to position HV, then
two laser beam will display on the wall surface as a
cross curve. Assume the intersect as point A, then
use right-angle setsquare to measure if the two
lines intersect at 90 degrees.
Note down point A and point M which is 2.5
meters away from point A at the level line.
Rotate the instrument to allow another intersect-
point B, which is five meters away from point A.
Measure distance E from point M to this level line.
E shall be within ±3mm.
At this time, assume a point C on the three meters
high perpendicular laser beam.
Distance between point A and point C shall be
within ±2mm.

When the instrument is not in used, the power
switch shall be turned OFF. Batteries shall be taken
out . Put the instrument back into its bag to avoid
unexpected damage.

Instrument: 1 piece
Carrying bag: 1 set
Operation Instrument: 1 copy
The instrument is kind of precision instrument
which shall not be heated or drenched, extruded by
force, collided or fallen for fear of influencing its
precision.
When not use, power switch shall be pushed to OFF
position and batteries shall be taken out after the
pilot lamp goes out. Lock the pendulum mass, and
put it back into the carrying bag.
Keep the instrument clean, use clean and soft cloth
to wipe glass of transmitting windows.

Find a smooth wall surface without vibration, which
shall be little affected by wind. Mount this instru-
ment five meters away from the wall surface.
Use a thread plumb to determine a perpendicular
point B on the ground, which is three meters high
from point A, another head of the thread plumb.
Turn the power and the instrument will be on the
automatic leveling condition.
Properly install the level rotator of the instrument
and put it on special support. Properly adjust the
leveling.
Turn the switch button(V/H) to position HV, then
two laser beam will display on the wall surface as a
cross curve.
Coincide the perpendicular laser beam with the
perpendicular point B on the ground.
