1.0 GENERAL
1.1 LASER SAFETY PRECAUTIONS
The KOHTECT AVV-711 alignment system is the class II laser device at typical wavelength of 670nm,
delivered output power of less than 1 mW and maximum radiant energy per pulse of 0.1 mJ. The Class II
laser comply with requirement outlined by USA’s FDA as well as international ANSI, BS 4803 and IEC
825 standard. Be sure to follow the following safety precautions to avoid personal injuries and damage to
the system
Do not look directly into laser the beam at any time!
Do not direct laser beam on to the people’s eyes!
ATTENTION!
Do not try open / dismantle measuring units and the display unit – this can damage the system, and your
after-sales service warranty will come void.
Warning!
Be sure the machines to be measured, cannot be started unintentionally as this can cause injuries. For
this purpose, before the mounting of equipment, either block the power switch in the “Off” position or
remove the safety fuses. These precautionary rules must be followed until the measuring system is
dismantled from the measured machine.

2.0 TECHNIC AL DESCR IPTION
2.1. DESIGNATION
AVV-711 alignment system (further as System) is designed for:
checking of shaft alignment of mechanisms;
The checking of shaft alignment means adjustment of the relative position of two coupled machines (e.g.
motor and pump) so that the centre line of the axis will be concentric when the machines are running
during normal working conditions.
