Precautions
•
Avoid directing the laser apertures towards the sun or other high-powered, infrared light
sources.
•
Avoid mechanical shock.
The laser is driven by a motor. When the unit is stationary the laser can be rotated by hand without
causing damage to the motor. If the laser is prevented from rotating by an obstruction, the motor
power will initially be increased to try to maintain the rotation speed but will then detect a stall
condition and the drive will be removed, preventing damage to the motor.
Caution:
If the obstruction is removed before a stall is detected the rotation speed may
momentarily be in excess of what it should be.
It is advised to minimise any manual movement of the laser and to keep the instrument away from
potential obstructions so the motor may turn freely.
WARNING:
Users should not manually or otherwise obstruct the operation of the
motor or allow clothing to come into contact with the device, to avoid entrapment
in the unit.
