MAINTENANCE

For the safe and lasting use of this machine, it is very important to do daily inspections from time to time. The items that should be checked include but not limited to the following:

Check the oil level in the pump’s crankcase. Fill it up if necessary. Change the lubrication oil (full-synthetic oil) after the first 30 hours’ work and then change the oil every 500 hours. The recommended oils are SAE 30, lSW-40, 20W-40.

Check the high-pressure hoses. Replace them if they have cracks.
Check the strainer. Clean it if necessary. This can avoid damage to the pump.
Check if there are air bubbles in the suction hose. Tighten the hose clips if bubbles are found between the water supply and the pump.
Check leakage, especially from the high-pressure connections. If there is leakage, stop the machine, release the pressure, and then tighten the connections.
Check the air intake grill of the motor. Clean it if necessary.
Check the wires. If wear or cracks are found, replace them.

Check the spray nozzle. Replace the nozzles when there are cracks on them or the pressure drops below the normal values. It is recommended to store some spare nozzles because they may be damaged by accidental collision.

Descaling must be carried out periodically, and this operation must be carried out by our after-sales service. Must use the specific descaling products since other inappropriate products may cause wear of the components. The interval of descaling depends on the water quality used and the frequency of use.

Frequent cleaning can keep the machine in good working conditions. Do not use acid materials, gasoline, or other flammable materials to clean this machine. Use the household detergent only. Never clean the machine itself with the high-pressure jet.

Storage for long periods. If this machine is left unused for long periods, it should be shielded against damage. Before storage, use non-alcoholic antifreeze products to flush the pump thoroughly.
