1. Before using the automatic paint spraying machine every day, you should check whether the grounding protection is intact. The grounding wire plays an important role in protecting the safety of equipment and personnel, and abnormal grounding is not allowed.
　　2. Before use, check whether the oil pipe is leaking or not, whether the gas pipe is leaking, etc., if any defects are found, deal with it in time before starting operation, and regularly or frequently check the hose and its connecting parts for leakage.
　　3. After stopping each shift, scrub the paint stains attached to the inner wall of the spraying space of the paint sprayer and the paint stains attached to the cylinder and hose to prevent the hose from hardening, and at the same time clean up all parts of the machine and the surrounding work surroundings.
　　4. Check the pollution and quantity of oil in the motor and worm gear box once a week, add or change the oil if necessary (normally, the oil needs to be changed once every six months).
　　5. Check the sprocket and chain lubrication of the paint spraying machine once a week and whether the chain is tensioned. If there is slack, adjust the tensioning wheel to tighten the chain.
　　6. Regularly replace the cleaning solvent in the roller brush box of the paint sprayer, and remove the paint dirt deposited in the box and on the roller brush.
　　7. Regularly or regularly remove the paint stains remaining on the conveyor belt of the line paint sprayer.
　　8. The spray gun should be kept clean frequently and cleaned carefully. Except for malfunctions or replacement of spare parts, do not disassemble the spray gun at will.
