Maintenance - JUKI PS900SB13090CKZ Instruction Manual

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. (Refer to
3) Replace the laser tube based on the frequency of use. If the laser tube fails to satisfy the require-
ments 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 every three month.
5) The water in the cooling water tank of the laser tube should be changed every time the laser tube
is changed together. The tank uses approximately five to six liters of commercially available pure
water.
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) After you have used the laser for four hours, remove the screw indicated with the arrow in the pho-
tograph. Pull out the drawer of the dust sucking box to clean it up (for removal of dust) 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. In some cases, blow the relevant parts with an air blower or disconnect the hose
to remove dust.
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.
