Instructions for use
1. The pump should be installed on a flat base less than 15 degrees to ensure the best lubrication conditions
2. Confirm the inlet size of the high-pressure pump piping. The inlet pipe diameter should be 1.5-2 times the inlet size of the pump. The inlet and outlet of the pump must be equipped with hoses to avoid pressure and fluctuations generated by the system. It is best to install accumulators to avoid bending of pipes.
3. The water supply pressure should be 1.5-8kg/cm2. The water supply temperature is below 70 Celsius degrees. The water supply system of the high-pressure pump must avoid the entry of air to ensure that the pump parts are not damaged.
Direction of rotation: The direction of rotation of the high-pressure pump is the direction in which the top of the pulley must face the pump head.
4. Before starting the motor-pump system, the following must be done
1). Check whether the crankcase lubricating oil is normal. If the oil level indicator of the gear box has only one engraved line, the oil level cannot be lower than the engraved line, but not higher than the engraved line 5mm. If the oil level indicator of the gear box has two Each line, the oil level is between the two lines.
2) Confirm that the valves of all pipes have been opened, and the medium can flow into the inlet of the pump and exhaust the air inside the system.
3) The operation of the high-pressure pump is not allowed to exceed the specified pressure, flow and speed.
4) Before spraying, the high-pressure nozzle should confirm whether the spray direction is safe. If there are unsafe factors, they should be eliminated in time to ensure safe production.
5. In order to remove the water in the pump to facilitate the placement in the freezing point environment, the pump can run for no more than 10 seconds under the condition of no water inlet.
6. For the system where the overflow valve is installed, the overflow pipe must be a hose. The overflow pipe should not be connected to the water inlet of the pump, but should be connected to the water tank or sewer.
7. When used for water storage tank, the suction line should use a hose of less than 3 meters, and the water level should be set higher than the height of the pump. If the water supply pressure does not reach the required pressure, it is recommended to use a booster pump.
8. Clean water should be used for the water supply, and a filter should be used on the supply line to prevent the inhalation of foreign objects.
9. Before operating the high-pressure pump, loosen the pressure regulating valve, and then gradually increase the pressure as needed after operation.
10. Lubricating oil should use SAE20W-50 or the same level of lubricating oil.
11. Lubricating oil should be replaced after 50 hours of initial use, and every 500 hours thereafter.
12. The water inlet filter should be regularly checked and cleaned.
13. All moving parts of the plunger pump must not be in a dry state.
14. High-pressure pumps are not allowed to use acidic, alkaline or corrosive liquids.

WARRANTY POLICY
TERM OF THIS WARRANTY:
Our company warrants to the original purchaser who uses the product in a consumer application (personal, residential or household usage) that all products covered under this warranty are free from defects in material and workmanship for one year from the date of purchase. All products covered by this limited warranty which are used in commercial applications (i.e., income producing) are warranted to be free of defects in material and workmanship for 90 days from the date of original purchase.
The warranty will not cover the following repairs and equipment:
1. Normal Wear: Pressure Washer needs periodic parts and service to perform well. This warranty also does not cover normal maintenance such as air filters, adjustments, fuel system cleaning and obstruction (due to chemical, lime, dirt, and so forth).
2. lnstallation and Maintenance: This warranty does not apply to equipment or parts that have been subjected to improper or unauthorized installation or alteration and modification, misuse, negligence, accident, overloading, overspeeding, improper maintenance, repair or storage so as, in our judgment, to adversely affect its performance and reliability.
3. Other Exclusions: This warranty excludes wear items such as quick couplers, seals, o-rings, pumps that have been run without water supplied or no oil filled damage or malfunctions resulting from accidents, abuse, modifications, alterations, or improper servicing or freezing or chemical deterioration. Accessory parts, such as guns, hoses, nozzle extensions (wands), and nozzles, are excluded from the product warranty. This warranty excludes used, reconditioned, and demonstration equipment and failures due to acts of God and other force majeure events beyond the manufacturers control.
