slit glass of the laser optical unit.
2. Pay close attention not to make an impact
or vibration on the laser optical unit
because it is a precise apparatus.
3. Place the removed laser optical unit so as
not to load on the polygonal motor.
4. Do not disassemble the laser optical unit
in the field because it is precisely
adjusted and very sensitive to dust and
stain.
5. Hold the laser optical unit vertically. Do
not press the top of the unit where the
polygonal motor is installed with your
hands or other things.
