(m) An arrow mark is provided on the side of the rear mirror, and a
line is drawn above the mark with a felt-tipped marker. If the line
has disappeared, look for a mark-off line. Place the rear mirror on
the holder. At this time, ensure that the reflecting plane (the
plane indicated by the arrow on the side of the mirror) of the rear
mirror does not face the holder but faces the opposite direction,
and that the arrow on the side of the rear mirror is aligned with
the round mark of the mirror holder. Insert the O-rings evenly so
that the mirror does not float.
Fig.8.2.1(d) Method of installing the mirror holder
(n) Install the mirror holder by reversing steps (b) through (d). The
mark on the mirror holder is provided on the bottom for C1000-E,
C2000-E, and C6000-E, and is provided on the side for C4000-E
and C5000-E.
Tighten the mirror holding screw then loosen it. Next, turn it by
fingers. After feeling a resistance, retighten the screw by 30
degrees.
(0) Turn on the main circuit breaker and the power supply of the
laser oscillator, and turn on the power to the CNC. Perform
evacuation. When the gas pressure (DGN. 905) reaches 100 or
less, retighten the mirror holding screw.
(p) Perform a leakage check.
(q) Install the power sensor. This completes cleaning and
replacement work.
(r) When the rear mirror is replaced, set a power input compensation
coefficient (PRM. 15215) again according to Section 8.5.
