7.10 Maintenance to dust removal fan
It is necessary to frequently check operation conditions of each part of dust collector during
operation, maintain each part, and pay special attention to checking the following critical
parts to ensure good operating conditions of equipment.
1. Check pressure difference change at air inlet and outlet of dust collector, and if there is any
abnormal decrease or increase of pressure difference, further inspection may be conducted
from damage of filter element or blocking.
2. Periodically check integrity of case to reduce air leakage rate of equipment.
3. Check pressure change conditions of compressed air for blowing. Air pressure shall be
controlled within 0.4-0.6MPa, which shall not be too low or too high, for its influence on dust
removal effects and service life of pulse valve.
4. Cable: check all conduits, cables and connection points for wearing and fracture.
5. Frequently check whether the pulse dust removal system of dust collector works normally. If
not, focus on checking whether the pressure regulating valve, control device, pulse valve,
solenoid valve and others on air bags are out of order or damaged, and timely repair or replace
them.
6. Check whether air fan and motor operate normally.
7. Check whether the dust discharge system is blocked.
8. Regularly clean up dust in the dust collecting car.
7.11 Maintenance of water chiller
1. Water chiller cannot be exposed to water swash or rain;

3. Laser water chiller which has not been used for a long time may cause water pump starting
difficulty at the first starting. Please lightly toggle engine Aaron;
4. It is forbidden to operate without cover if there are any live, operating and high-temperature
parts inside;
5. By no means is the machine allowed to operate with no water, for it will cause damage to the
machine;
6. The water tank used in this machine cannot be fully filled to prevent liquid spoiling during
operation;
7. Make sure to operate in a well-ventilated environment;
8. Be sure to cut off power before maintenance, and operate five minutes after cutting off the
power;
9. Wipe machine surface with neutral detergent;
10. Clean filter screen of the condenser every week;
11. Check water quality in water tank every month;
12. Check the filter in laser water chiller every two months, and timely clean up if there is any
foreign matter;
