or use of this product.
To prevent
serious injury
from accidental
operation:
Turn the Power Switch to Off

To prevent
serious injury
from accidental
operation: Turn Power Switch
to Off before adjusting Level.
Assembly
1.
Remove the tripod from the case.
2.
Open tripod’s legs and adjust positioning
of each leg until base is level. Use
bubble level in tripod base as a guide.
3.
Remove the Laser Level from the case.
4.
Install batteries, making sure to align
batteries according to indicated polarity.
5.
Attach the Laser to the tripod base. Do
this by threading the bolt at the top of the
tripod through the holes at the center of
the Laser Level’s lower base.
6.
Level the Laser by using the tri-brack
adjustment screws until the bubbles are
centered on the two levels.
7.
Loosen the brass screw located under
the center of the Laser Level’s upper
base until the pendulum lock is released.
8.
Turn on the Laser. Allow the laser lines
to stabilize for 4 to 6 seconds before
starting any measuring or leveling tasks.
9.
To disassemble and store, follow the
above directions in reverse. Please
note: Retighten the brass screw under
the Laser Level before continuing. This
will lock down the pendulum during
disassembly.
1.
After removing the Laser from the
Carrying Case, open the battery
compartment, insert the three “AA”
Batteries into the battery compartment
according to the polarity symbols
shown inside, and close the battery
compartment door.
2.
Be sure to set the Laser on as flat a
surface as possible. The tri-brack
adjustment on the base of the level can
be used to help level the unit. (Turn each
of the knobs to either raise or lower that
corner.) The self-leveling range of the
Laser is within ± 6°. Use the 2 Vials on
the base to verify that the base is level.
3.
Release the Pendulum Lock on the
bottom of the Laser Level, by loosening
the Brass screw in the center.

4.
Press the button for the desired line(s)
2.
on the top of the unit to switch “on”. The
LED for the line will turn on when that
line is switched on.
Press both the horizontal and vertical
buttons to project a laser cross on wall
A. Mark point a1 at the intersection of the
beams. Turn the cross line laser 180°
and repeat on wall B, marking point b1 at
the intersection of the beams, see below.
5.
The Laser Level will work properly if it is
positioned within its self-leveling range.
3.
6.
Allow 4-6 seconds for the horizontal and
vertical Laser lines to be stabilized. After
stabilization, the Laser lines can be used
for measurement reference. Laser lines
may swing slightly due to vibration from
surroundings.
Move the instrument straight towards
wall A to a point 2 ft. away and repeat
step 2, marking the intersections as a2
and b2, see below.
7.
To prevent damage to the level, tighten
the pendulum lock after use and store in
the carrying case.
4.
a distance (da)=|a1 -a2|
b distance (db)=|b1 -b2|
If |da - db| <1mm, the accuracy is
within tolerance. Otherwise, return the
instrument to a qualified technician for
repair.
Accuracy Checking
NOTE: Due to the complicated, sensitive
nature of these procedures, ordinarily
only a qualified technician would attempt
them.
Level Beam Accuracy
1.
Set up the instrument with the
Tripod centered between two walls
approximately 16 ft. apart. Please ensure
the Rotary Base is level.

Horizontal Beam Level Accuracy
(End to End)
1.
Set up the instrument with the Tripod
approximately 16 ft. from the wall.
Please ensure the Rotary Base is level.
2.
Press both the horizontal and vertical
buttons to project a laser cross on
the wall, mark point a 8 ft. from the
intersection of the beams to the right on
the horizontal beam.
3.
Turn the instrument until the vertical
beam has moved 16 ft. to the right side,
and mark b 8 ft. from the intersection of

batteries.
b
16 ft.
4.
If the distance between a and b is less
than or equal to 2mm, the accuracy is
within tolerance. Otherwise, take the
instrument to a qualified technician for
repair.
Vertical Beam Level Accuracy (End to End)
1.
Set up the instrument with the Tripod,
approximately 16 ft. from the wall. (The
wall should be at least 17 ft. high).
Please ensure the Rotary Base is
approximately level.
2.
Press both the horizontal and vertical
buttons to project a laser cross on
the wall, mark point A 8 ft. above the
intersection of the beams on the vertical
beam.
3.
Use A as a starting point and nail one
end of a string with plumb bob (not
included) on A. The length of the string
should be 16 ft.
4.
Mark M1 16 ft. from point A on the string.
5.
Mark M2 8 ft. below the intersection of
the beams on the vertical line.
6.
Measure the distance between M1 and
M2.
7.
If the distance is less than or equal to
2 mm, the accuracy is within tolerance.
Otherwise, take the instrument to a
qualified technician for repair.
