2. MAINTENANCE
1) Observe the cooling water tank of the laser to check whether the water normally circulates in the
tank to ensure that the laser tube is not clogged inside.
2) Wipe the reflecting mirror surface with alcohol once every half month to keep it clean and to im-
prove its reflecting effect. Wipe the focusing lens inside the irradiation cylinder with alcohol from
time to time to keep it clean.
3) Carry out replacement of the laser tube according to the frequency to be used. If the laser tube fails
to satisfy the requirements for cutting the material, change the laser tube with an appropriate one.
4) For the cooling water tank of the laser tube, change the pure water (approximately 5L - 6L) in the
tank periodically once a week.
5) The water in the cooling water tank of the laser tube should be changed every time the laser tube is
changed together. Potable pure water of approximately 5L - 6L is used in the cooling water tank.
6) Check the hose of the tank and laser tube periodically once every three months and change it with
a new one if necessary in order to prevent a broken tube from negatively affecting smoking and
cooling.
7) Adjust / calibrate the laser path once every six months to ensure that the laser beam is focused
without distortion.
8) Clean up the drawer type dust sucking box located under the front stage of the laser every time you
have used the laser for four hours in order to prevent a fire from occurring.
9) Thoroughly inspect and carry out cleaning of the following parts every time you have used the laser
for eight hours to prevent accumulation of dust and deterioration of the tube, thereby preventing a
fire from occurring.
① Clean up litter in the upper smoking tube.
② Clean up litter in the lower smoking tube (Loosen the screw in the cover on the table. Clean up
litter at the tube opening and in the tube with a tool or small wooden stick).
③ Clean up litter accumulated in the dust suction opening, outlet and exhaust pipe of the suction
fan.
10) Immediately carry out inspection and maintenance according to the instructions displayed on the
operation panel.
Service life of the laser tube: Approximately six months. Service life of the focusing lens and reflect-
ing mirror: Approximately one year. Periodical cleaning is required to prevent foreign matters from
attaching them.
C: Reflecting mirror of the laser
D: Focusing lens of the laser
E: Laser tube
It is prohibited to observe the laser
tube with an optical telescope or
directly look at the optical path while
the laser is in operation, from the
locations as shown in the figure.
