Routine maintenance

Check and keep the oil tank of the manual grease pump filled with grease before starting the machine and after washing the whole car after the pumping. After the clean grease has spilled, you can. During the working process, pull the handle of the manual grease pump 10 times every 1 hour. The small aggregate concrete pump lubrication system should be kept clean to prevent the entry of dust and other impurities, and do not contact with acid and alkali substances, and the system should be cleaned every 500 hours of operation. When the coating (0.2-0.25mm) of the conveying cylinder is not worn off and concrete slurry or sand appears in the rear of the concrete piston, that is, the water tank, it indicates that the piston has been worn and the concrete sealing body, guide ring and dustproof ring should be replaced immediately.
