Operating Notes & Safety Instructions

1. Installation and Site Preparation

● The High-pressure mixer truck car washer must be installed on a flat, hardened concrete foundation with sufficient load-bearing capacity to avoid vibration or deformation.

● Reserve a reasonable drainage ditch and sedimentation tank to ensure smooth sewage discharge and water circulation.

● Keep the installation area ventilated and free of accumulated water to prevent electrical components from dampness.

2. Power Supply Safety

● Use a three-phase four-wire 380V 50Hz power supply with stable voltage; do not connect power privately.

● The equipment must be reliably grounded to prevent electric leakage and electric shock.

● Do not start the machine when the voltage is unstable or the circuit is faulty.

3. Operation Process Rules

● Vehicles must enter the washer at low speed (less than 5 km/h) and stop at the marked position.

● Prohibit people from standing inside the washing area during operation to avoid high-pressure water injury.

● Do not open the control cabinet or touch pipes and nozzles during machine operation.

● If abnormal noise, water leakage or circuit failure occurs, press the emergency stop button immediately and check after shutdown.

4. Water System Management

● Use clean tap water or recycled water after sedimentation and filtration; prohibit using water with excessive sediment to avoid blocking nozzles and pumps.

● Check water level and filter regularly; clean or replace the filter element when clogged.

● In winter, drain all water inside pipes and pumps after shutdown to prevent freezing and cracking.

5. Daily Maintenance Requirements

● Clean the nozzles, sensors and frame surface after each shift to remove mud and concrete residue.

● Regularly check whether pipe joints are tight and nozzles are unblocked; replace damaged parts in time.

● Regularly check the running state of the water pump and motor; keep the control cabinet dry and clean.

6. Sensor and Control System Protection

● Keep infrared sensors clean and unobstructed; do not cover or collide with them.

● Set washing time and pressure reasonably; do not modify PLC parameters without permission.

● In case of control failure, switch to manual mode and contact maintenance personnel in time.

7. Vehicle Washing Requirements

● Close the truck hopper and doors before washing to prevent water from entering the cab.

● Prohibit overloaded, overheight or oversized vehicles from entering the washer to avoid equipment damage.

● Do not stay in the washing area for a long time to avoid affecting service life.                      

8. Personnel Management

● Operators must read the manual and receive training before taking post.

● Non-professionals are prohibited from disassembling, modifying or repairing the equipment.

● Equip warning signs and protective facilities to keep irrelevant personnel away from the working area.

9. Long-Term Shutdown Notes

● Cut off power and water supply before long-term shutdown.

● Drain all water in the pump, pipes and control system.

Before and After Using

1. Vehicle Cleaning Status

Before use: Vehicles are covered with thick concrete residue, sediment, mud and dust. Tires, chassis and hopper have a lot of attachments that are hard to clean manually. The vehicle body is dirty, which affects driving safety and easily causes road pollution.

After use: The whole vehicle is thoroughly cleaned. Tires, chassis, hopper and body are free of concrete residue and mud. The vehicle is clean and tidy, fully meeting the site environmental protection requirements.

2. Water Consumption

Before use: Manual cleaning uses water randomly, with large waste and high water consumption, up to 500–800L per vehicle.

After use: High-pressure fixed-quantity water outlet, equipped with optional water circulation system. Water consumption is only 130–180L per vehicle, saving more than 70% of water.

3. Site Environment & Environmental Protection

Before use: Mud and sewage flow randomly, dust flies, and the site is messy. It is difficult to pass environmental protection inspections and may face fines.

After use: Sewage is collected and discharged centrally, no mud splashing, no dust pollution. The site is clean and tidy, stably meeting environmental protection standards.

4. Equipment & Vehicle Service Life

Before use: Long-term attachment of concrete and sediment accelerates vehicle corrosion and aging. Manual washing with hard tools is easy to damage the vehicle surface.

After use: High-pressure water cleaning does not damage the vehicle body. Timely cleaning reduces corrosion and effectively extends the service life of mixer trucks and cleaning equipment.
