Westinghouse ePX3500 Electric High Voltage Cleaning Machine

(2) Cleaning with cleaning agent

Preparation: Pour the specialized cleaning agent for the high-pressure cleaning machine into the soap box in proportion and cover the box tightly.

Replace nozzle: After turning off the power and releasing the pressure, remove the current nozzle and install the soap nozzle.

Cleaning operation:

Turn on the water source and power, press the trigger, and wait for 3-5 seconds (to allow the cleaning agent to be sucked into the pipeline) until the water flow contains the cleaning agent.

Spray at a uniform speed onto the dry surface, ensuring even coverage of the cleaning agent, and let it sit for 1-2 minutes (do not dry out).

Turn off the power, replace with a 25 ° nozzle, turn on the water source and power, rinse the surface with clean water until there is no residue of cleaning agent.

Follow up processing: Empty the soap box, pour in clean water, install a soap nozzle, press the trigger to flush the pipeline for 1 minute to avoid blockage caused by residual cleaning agents.

3. Daily maintenance and regular maintenance

(1) Maintenance after each use (completed within 5 minutes)

Cleaning nozzle: Remove the nozzle, use specialized cleaning tools or fine needles to clean impurities (such as mud, residue of cleaning agent) in the nozzle hole, and then rinse with clean water.

Cleaning the inlet filter: Unscrew the inlet connector, remove the filter, rinse it with clean water, and reinstall it to ensure that the filter is not damaged (missing the filter can cause impurities to enter the pump body and cause wear).

Drain residual water from the pipeline: Turn off the water source, press the trigger to release residual water, disconnect the high-pressure hose and garden hose, tilt the machine body to drain the accumulated water in the inlet.

Cleaning the body: Wipe the dust and stains on the surface of the body with a damp cloth, do not rinse the body with high-pressure water flow (to avoid water ingress to electrical components), and do not use corrosive cleaning agents such as gasoline and solvents.

(2) Regular maintenance (monthly/every 20 hours of use)

Check the high-pressure hose: Check whether the hose is damaged, bulging, loose joints, and whether the sealing ring is aging (if there is water leakage, replace the sealing ring or hose).

Lubrication sealing ring: Apply a small amount of non water soluble grease (such as Vaseline) on the sealing ring of the high-pressure hose joint and spray gun interface to extend the service life of the sealing ring.

Test GFCI plug: Follow the steps of "leakage protection maintenance" mentioned earlier to ensure that the protection function is normal.

Check nozzle wear: If the nozzle hole becomes larger and the spraying direction deviates, it indicates that it has been worn and needs to be replaced (wear can cause a decrease in pressure and cleaning efficiency).

(3) Long term storage and maintenance (not used for more than one month)

Thoroughly clean: Follow the "maintenance after each use" steps to clean the nozzle, filter screen, and pipeline, ensuring that there is no residual cleaning agent.

Drain water: Disconnect all pipelines, press the trigger to release residual water in the pump body, and tilt the machine body for multi angle drainage.

Pump body protection: It is recommended to use commercial pump body protectants (operate according to the instructions) to prevent the pump body seals from drying out and rusting inside.

Storage requirements:

Store in a dry, ventilated, and heated room with a temperature not lower than 4.5 ℃ (to prevent residual moisture from freezing and expanding, which may cause the pump body to crack).

Disassemble the nozzle, spray gun, and extension rod, clean them and place them in the storage rack. Wrap the high-pressure hose and cable neatly to avoid squeezing or bending.

Stay away from flammable materials, high temperature sources (such as heating, stoves), and corrosive gas environments.

Common troubleshooting (quick problem-solving)

Possible causes and solutions for fault phenomena

The machine cannot start. 1. The power supply is not connected properly or the GFCI plug is not reset; 2. The system pressure has not been released; 3. Motor malfunction: 1. Check if the plug is securely plugged in and press the GFCI "RESET" button; 2. Press the trigger of the spray gun to release pressure; 3. If it still cannot be started, contact after-sales service

There is power supply but no water flow/intermittent water flow. 1. The water source is not turned on or the water pressure is insufficient; 2. The inlet filter is clogged; 3. nozzle blockage; 4. Hose bending/leakage 1. Turn on the faucet and ensure that the water source pressure is ≥ 20 PSI; 2. Disassemble and clean the inlet filter screen; 3. Clean or replace the nozzle; 4. Sort out the hoses and check if the joints are tightened

Insufficient pressure: 1. nozzle wear or blockage; 2. Low water source pressure; 3. Aging of hoses (internal collapse); 4. Wear of pump body seal 1. Clean or replace the nozzle; 2. Change the water source (such as taking water from a bucket and switching to tap water); 3. Replace the high-pressure hose; 4. Contact after-sales service for pump body maintenance
