Maintenance and troubleshooting of washing machines

After the new machine is used for 20 hours, the oil must be changed, and when the oil is drained, it can be turned on and run for 2-3 minutes, and then the oil is drained by the oil drain. Diesel fuel is then injected, the pump chamber is cleaned until the released diesel is clean, and then the oil is re-injected. This is very important to extend the service life of the implement. After 100 hours of cumulative use, the oil is changed in the same way, and the oil is changed every 100-200 hours thereafter. When not used for a long time, the remaining water in the pump should be drained by leaving the inlet pipe from the water supply system and starting to dehydrate for about 1 minute. At the same time, remove the remaining water in the inlet pipe and the outlet pipe, and open the trigger valve when the outlet pipe is drained.
