HAMAR LASER L-705 User manual

WARRANTY
Hamar Laser Instruments, Inc., warrants each instrument and other articles of
equipment manufactured by it to be free from defects in materials and
workmanship under normal use and service, its obligation under this warranty
being limited to making good at its factory any instrument and other article of
equipment which shall, within one year after shipment of each instrument and
other article of equipment to the original purchaser, be returned intact to Hamar
with transportation prepaid, and which Hamar’s examination shall disclose to
Hamar’s satisfaction to have been thus defective; other than this express
warranty, Hamar neither assumes nor authorizes any other persons to assume for
it any other liability or obligation in connection with the sale of its products.
This warranty is not applicable to instruments or other articles of equipment
manufactured by other companies and limited by a warranty extending for less
than one year. In such an event, the more limited warranty applies to said
instrument or article of equipment.
This warranty shall not apply to any instrument or other article of equipment
which shall have been repaired or altered outside the Hamar factory, or which
has been subject to misuse, negligence, or use not in accord with instructions
furnished by the manufacturer.

Critical Note on Calibration
When configuring the R-1307 Readout, it is critical to match the target ID with the target ID
identified on the serial number of the target. For example, if the target ID on the target serial
number label is 2, then the R-1307 must also be set to the number 2. If the target and readout and
not matched, a centering error of up to .004 in. (0.10 mm) can occur. In addition, the laser switch
setting (CONT. or Fixed vs. PULSE) must also agree with the R-1307 Readout setting (F10.10 vs.
P10.10).
For example:  .. or  .. for R-1307 #2
For more information on the Pulse/CONTinuous modes on the laser, see Pulse/Continuous Modes (L-705
and L-706 Lasers) on Page 5. For complete information on matching the target to the readout, see
Configuring the R-1307 Readouts on Page 9.

The L-705 Hinge Line Alignment System
Hamar Laser’s Hinge Line Alignment System has been a proven performer in the aerospace industry for
many years. In fact, the first hinge line system Hamar Laser delivered revolutionized the industry by
reducing an 8-hour job, requiring eight workers and four theodolites, to one that took only two workers
less than an hour to complete. In addition, accuracy was significantly higher and the results were
consistently repeatable. Currently, several aircraft builders are using this alignment system to accurately
align hinge-pin bushings in tooling fixtures and vertical and horizontal stabilizers.
Model L-705 Laser
The L-705 Bore Laser is a battery-operated,
visible light laser that mounts magnetically
in a bore fixture or mounting. It is suitable
for almost all bore applications. The laser
has two mounting surfaces: 0.7498 in. (19.04
mm) and 2.2498 in. (57.14 mm). The laser
beam is centered to both mounting ODs to
within .0003 in. (0.08 mm). The L-705 laser
beam is designed to shoot up to 110 ft. (33
m) but has an angular adjustment resolution
of .001 in. (0.025 mm) in 50 ft. (15 m) and is
best used under 50 ft.
The L-705 Laser has been designed with a
standard aerospace tooling diameter of 2.25
in. (57.15 mm). The centering of the laser
beam to the housing is controlled to
extremely tight tolerances, usually less than
.0005 in. (.013 mm). Built-in micrometers
on the back of the laser control the angle
adjustment of the laser beam. These two
features eliminate the steering fixture and a
reference target, making the task of aligning
large floor assembly jigs fast and accurate.
