GB 6. On the ceiling, mark two short lines
b
and
c
where the
front and side laser beams cross.
7. Pick up and rotate the laser 180 º , and position the down
dot directly over
a
, the previous position of the down dot,
as shown in Figure
G
#3.
8.
On the ceiling, look at the position of the two laser beams.
If they are not parallel to marked lines
b
and
c
, turn the
laser until the laser beams are closely lined up with
b
and
c
.
9.
On the ceiling, mark two short lines
d
and
e
where the
beams cross.
10. Measure the distance between marked lines
b
and
d
,
and marked lines
c
and
e
.
11.
If your measurement is greater than the Allowable
Distance Between Marked Lines for the corresponding
Ceiling Height in the following table, the laser must be
serviced at an authorized service center.
Ceiling Height
Allowable Distance
Between Marked Lines
2.5m (8
′
) 1.5mm (1/16")
3m (10
′
) 2.0mm (3/32”)
4m (14
′
) 2.5mm (1/8”)
6m (20
′
) 4mm (5/32”)
9m (30 ′ ) 6mm (1/4”)
90º Between Vertical Beams
Checking 90º accuracy between the front and side vertical
beams requires an open floor area at least 6m x 3m (20
′
x 10
′
).
1.
Place the laser on a smooth, flat, stable surface that is
level in both directions, as shown in Figure
H
#1.
2. Turn the laser ON.
3.
Press three times to display the front and side vertical
beams.
4. Press twice to display the down dot .
5. Along the front laser beam, mark three locations
a
,
b
, and
c
; where
b
is at the midpoint of the laser beam.
6. Position the laser so the down dot is over
b
and the front
laser beam is aligned with
c
(Figure
H
#2).
7.
Mark a location
e
along the side laser beam at least 3m
(10’) away from the laser.
8. Turn the laser clockwise 90º.
9.
Position the laser so the down dot is over
b
and the front
laser beam is aligned with
e
(Figure
H
#3).
10. Along the side laser beam, mark
f
near
a
.
11.
Measure the distance between
a
and
f
.
12. If your measurement is greater than the Allowable
Distance Between
a
&
f
for the corresponding
Distance from
b
to
a
in the following table, the laser
must be serviced at an authorized service center.
Distance from
b
to
a
Allowable Distance
Between
a
&
f
3m (10 ′ ) 3.2mm (1/8”)
4m (14 ′ ) 3.5mm (5/32”)
5m (17 ′ ) 4.5mm (3/16”)
6m (20 ′ ) 5.5mm (7/32”)
7m (23 ′ ) 6mm (1/4”)
Using the Laser
Operating Tips
• Always mark the center of the beam created by the laser.
• Extreme temperature changes may cause movement of
internal parts that can affect accuracy. Check your accuracy
often while working.
• If the laser is ever dropped, check to make sure it is still
calibrated.
• As long as the laser is properly calibrated, the laser is self-
leveling. Each laser is calibrated at the factory to find level as
long as it is positioned on a flat surface within average ± 4°
of level. No manual adjustments are required.
• Use the laser on a smooth, flat, level, surface.
Turning the Laser Off
Slide the Power/Transport Lock switch to the OFF/Locked
position (Figure
A
#1a) when the laser is not in use. If the
switch is not placed in the Locked position, the laser will not
turn off.
