Install the roller: Tilt the body, align the roller with the bottom slot, and push it in firmly until you hear a "click" sound, ensuring that the roller is securely installed (you can gently shake it for testing).

Fixed storage components: Align the spray gun storage rack, hose storage rack, and cable storage rack with the reserved card slot on the body, slide them into place, and tighten the fixing screws (if any).

Connect high-pressure hose:

Take out the high-pressure hose, align one end with the water outlet of the machine body, press the hose buckle and push it in, and tighten the locking ring clockwise.

Align the other end with the spray gun interface, press the buckle and tighten it, gently pull the hose to confirm a secure connection.

Connect water source:

Check if the filter inside the water inlet of the aircraft is intact and unobstructed (if there are impurities, rinse with clean water).

Connect one end of the garden hose to the faucet and the other end to the water inlet of the machine. Tighten the buckle clockwise and turn on the faucet to test for water leakage.

Assemble spray gun and nozzle:

Insert the extension rod into the spray gun interface, tighten clockwise (do not apply excessive force to avoid damaging the thread), and gently pull to confirm fixation.

Select the desired nozzle, align it with the front end interface of the extension rod and press it. Once you hear the snap sound, it will be installed in place; Press the buckle and pull out the nozzle during disassembly.

2. Usage steps (divided into regular cleaning and cleaning with cleaning agents)

(1) Regular cleaning (without cleaning agents)

Preparation before startup:

Turn on the faucet to ensure smooth water flow and no impurities.

Unlock the safety lock of the spray gun trigger, press the trigger to release the air and residual impurities in the pipeline until there are no bubbles in the continuous water flow, and then lock the safety lock.

Insert the power plug into the grounding socket and ensure that the plug is dry.

Startup and Cleaning:

Press the "start stop button" on the machine body, and the machine will automatically stop after running for 1-2 seconds (the automatic start stop function is normal).

Unlock the trigger safety lock, press the trigger, the machine starts and sprays high-pressure water flow to start cleaning.

Cleaning technique: Starting from the bottom of the surface, clean upwards in a left-right translation to avoid water flow from top to bottom (which may leave water marks); For stubborn stains, the distance between the nozzle and the surface can be shortened (but not less than 15cm), or the 0 ° turbine nozzle can be replaced.

Shutdown operation:

Release the trigger, the machine will automatically stop, and lock the trigger safety lock.

Turn off the faucet and press the trigger to release any residual pressure in the system.

Disconnect the power supply, wrap the cable around the storage rack, wrap the high-pressure hose around the hose storage rack, and place the spray gun into the storage rack.

(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
