(4) Put the top part of the reflector slowly so that the punch mark on the stainless
part may come to the + sign printed on the laser chamber.
⇒ Be careful of the direction of the reflector. Damage may be caused to the lamp.
(5) Wipe off the waterdrops attached on the rear side of the top lid of the laser
chamber, and then install the top lid of the laser chamber.

Making an Operation Check
(1) Turn ON the MAIN SWITCH switch.
(2) Pull the end of the lamp-replacing cover interlock switch to release interlock.
Check that the LED lights up.
(3) Turn ON the CONTROL keyswitch to run the cooler to check for water leakage.
⇒ If water leakage occurs, turn OFF the CONTROL keyswitch and the MAIN
SWITCH switch immediately. In 5 minutes or more, wipe out leaked water and
remove the cause for water leakage. Then, operate the cooler again to make
sure that no water leakage occurs.
⇒
When the CONTROL keyswitch is turned ON, a bit of water may ooze out from
the clearance between the laser chamber and the top lid. This is due to pushed
waterdrops around the packing groove and is not abnormal. Wipe them out with
a clean cloth.
⇒
If water leakage occurs during an operation check, tighten the 8 bolts of the top
lid of the laser chamber within the maximum tightening torque of 550 cN•m (55
kgf•cm) and the make sure that no leakage occurs.
(4) Make sure that the laser welder can be normally operated and then turn OFF the
power supply of the laser welder.
