Pay attention to details when operating a pressure washer

Daily maintenance of pressure washer:

(1) Remove the pin/brush and clean it with special detergent.

(2) Discharge the water in the sewage tank and water tank and rinse with water. Check the sewage tank for debris. If so, remove it immediately.

(3) Lift the wiper part from the ground and scrape it clean with a wet towel.

(4) Cleaning float filter device for washing.

(5) The machine will be cleaned with certain detergent.

(6) Rechargeable batteries.

(7) Check whether the edge of the scraper is sharp. If it is damaged, please turn it back for use or replace it.

Regular maintenance measures to be done:

1. Regularly clean the precipitated impurities in the tank, and timely add enough oil to ensure the healthy operation of the engine can extend the operation life of the engine.

2. when the operation is completed, it is necessary to cover it with protective sleeves in time to avoid corrosion, premature wear and adhesion dust caused by a part of the blockage. And often to the valve and sealing ring coated with lubricant, to prevent the next use of stuck.

Requirements for operators

(1) In the process of operation, the operator must not let the machine in unsupervised condition.

(2) Technical personnel need to check all the circuit interfaces frequently.

(3) Technical personnel need to check all working fluids frequently.

(4) The operator needs to always insist that hands and feet do not touch the cleaning nozzle.

(5) Technical personnel need to check whether the hose has cracks and leaks.

(6) Operators should wear appropriate goggles, gloves and masks during operation to ensure the safety of the face.

(7) It is assumed that before the use of the airbrush, the trigger will always be set on the demand for safety.

(8) Always choose as low pressure as possible to carry out the operation, but the pressure must be able to ensure that the end of the operation under the premise of selection.

(9) The operator must not start the equipment before checking that all hose joints have been determined in situ.

(10) The operator should never point the airbrush at others or himself during the operation.

(11) Before the operator disconnects the hose, it is necessary to release the pressure in the cleaning machine first.

(12) Never start the equipment until the supply water is connected and the proper flow of water passes through the gun rod. Then the required cleaning nozzle is connected to the spray gun rod for operation.

(13) The operator must drain the water in the hose after each use.

Precautions for pressure washers

1. When operating: always wear appropriate goggles, gloves and mask.

2. Always keep hands and feet away from the cleaning nozzle.

3. Always check all electrical connectors.

4. Check all fluids regularly.

5. often check whether there are cracks and leaks in the hose.

6. when the nozzle is not used, always need to set the trigger in the safe lock state.

7. Always work with as little pressure as possible, but enough to get the job done.

8. before disconnecting the hose, always release the pressure in the cleaning machine.

9. Always drain the hose after each use.

Common faults and solutions of high pressure washer

1. Screams occur during internal operation

The main reason for this failure is caused by the lack of oil in the motor bearing. At this time, we need to inject butter into the oil filling hole of the motor in time. This kind of failure in the daily use of not much, our daily maintenance in the use of regular maintenance can effectively avoid the occurrence of this phenomenon.

2. Abnormal sound occurs when the high pressure water pump is running

The abnormal sound occurs when the high pressure water pump is running because the air is inhaled in the pump or the flow valve spring is damaged. Once this phenomenon occurs, it is recommended that the manufacturer assist in maintenance.

3. The water outlet pressure is not stable when it is large or small

The instability of the water pressure is mainly caused by the air inhaled by the high-pressure water pump or the water inlet pipe. At this time, it is necessary to check whether the pressure of the water source is enough and whether the filter device of the water inlet is blocked. If the water filter screen is found to be clogged with debris, the filter screen should be removed and cleaned with water.

4. Oil leaks at the bottom of the high-pressure water pump

The bottom of the pump is leaking oil because the oil seal in the pump is damaged, which requires us to replace the oil seal in time. When the high pressure pump is running, the crankshaft and connecting rod are in constant motion, then it is necessary to rely on the oil to give proper cooling and lubrication, so the high pressure pump can not lack of lubricating oil.

5. After running for a period of time, the water pressure decreases

After working for a period of time, the pressure will be reduced. This phenomenon first of all, we should check whether the high pressure nozzle of the cleaning machine has blockage and wear phenomenon. The high pressure nozzle of ordinary pressure equipment will not appear wear phenomenon basically, because the high pressure nozzle of our equipment has been specially treated and the high pressure nozzle of ultra-high pressure equipment is difficult to ensure. Secondly, it is necessary to check whether the seal assembly inside the pressure regulating valve and the water pump is normal. If there is leakage, the fittings should be replaced in time.

6. The pressure of the regulating valve is normal and the water pistol is not discharged

In the process of use, the pressure of the regulating valve may be normal, but the water from the high-pressure water gun may not be discharged or the water sprayed by the high-pressure nozzle may be irregular. First, we will check whether the filter is blocked, and then the spray will be abnormal if the nozzle is blocked with foreign matter.

7. automatic stop when working

There are more reasons for this problem. We check whether the power socket is in bad contact. Whether the switch is damaged due to damage. Whether the motor temperature protector starts or not, wait a few minutes for the motor to cool itself before starting up. The stop function of water gun without release of pressure works.
