INSTRUMENT
Casing made of heavy duty cast aluminium, water- and dustproof (tested to 1 bar overpressure). Purged
with nitrogen to avoid condensation (6). Replaceable optic guard window (4) covers the aperture and
protects the optics.
MOUNTING BRACKET
Made of heavy duty aluminium. Alignment screw pairs are precision fine thread, counter acting to allow
locking of position. Tangent alignment screws (2) at the back face, vertical alignment screws (7) on top. Two
mounting functions: 5/8” threaded hole on the underside (3) for mounting on tripod or standard instrument
bracket, and mounting point for 1” steel pin (5). Convenient carrying handle (1) on top of instrument.

2.1 POSSIBLE CAUSES OF FAILURE
If the laser beam is not lit when the power source is connected, check the following:
1. Check that the power source is functional within specification above. For the 12/24VDC version, check
if the battery is properly charged, or that the power converter is functional and properly connected to
mains AC supply. For the 110/23VDC version, check that the mains AC supply is operational.
2. The fuse may have been blown. For the 12/24VDC version, the fuse is self resetting. Allow some
minutes to pass and try starting the instrument again.
3. If none of the above actions are successful, and the instrument is still unoperational, contact your AMA
dealer, or AMA Laser Systems AB for service repair.
4. If the beam size is larger than specified above, the optics have been damaged, and the instrument must
be repaired.
5. If the instrument is damaged by blast rock, you should let your AMA dealer check for leakage and
shock damage. This is especially important if the optic guard window has been cracked. If the
instrument is no longer waterproof, the repair costs will be significantly higher if water or dust enters the
instrument.
2.2 LASER SAFETY CONSIDERATIONS
The T8 tunnel laser complies with laser safety class 3R. The laser light is max 5mW, and is considered
harmless under normal usage. The laser light is visible at wavelength 635nm. The human eye will adapt
quickly to protect itself if exposed, and the laser classification levels are set so that the absorbed laser energy
will not cause permanent damage to the eye. For your own convenience, you should avoid direct exposure
to the laser light, and avoid prolonged staring at sharp reflections of the laser light. For more detailed
instructions, please refer to national occupational hazard regulations.
2.3 CE CERTIFICATION
The T8 Tunnel Laser (Part no:s AM51000 for 12/24VDC supply, AM51000-1 for 110/230VAC supply)
fulfills the requirements of conducted and radiated emission according to EN55011 limit A. It complies with
EN61000-6-4:97, and EN61000-6-2:99.
The T8 110/230VAC-version (AM51000-1) fulfills the requirements of transient immunity according to
EN61000-4-5, 2kV and 2kV differential respectively common-mode coupling on power leads (performance
criteria B).
The T8 12/24VDC-version (AM51000) fulfills the requirements of transient immunity according to
EN61000-4-5, 0.5kV and 0.5kV differential respectively common-mode coupling on power leads
(performance criteria B).
2. OPERATING INSTRUCTIONS
1. Mount the T8 with consideration to desired working distance, and minimize the risk for accidental hits
by trucks etc.
2. Connect the power cable to appropriate power source (12/24VDC or 110/230VAC depending on
instrument type). The laser beam is lit when the instrument is powered up.
3. Let the instrument warm up during one half hour.
4. Align the laser beam using the two pairs of alignment screws. Tighten the screws for secure position
after alignment is achieved.
5. For added protection it is recommended that steel plate targets are fixed to the rock wall at approx. 5m
and 20-50m distance. Drill a 20-30mm hole to allow laser beam to pass. This plate protects against
blast rock damage, and is an easy check that the instrument is still properly aligned after blasts.
6. To shut the instrument off, disconnect the power source.
