01 Intended use
For outdoor flushing and drainage with continuous water supply and sewage collection conditions, focus on the overall water capacity and downstream treatment; do not equate high flow rates with faster completion of all tasks.
This machine is more suitable for outdoor flushing and drainage areas with continuous water sources and discharge conditions. The machine's overall flow rate of 75 L/min focuses on the requirement for carrying away debris. The work is organized in segments based on the inspection wells.
For outdoor flushing and drainage with continuous water supply and sewage collection conditions, focus on the overall water capacity and downstream treatment; do not equate high flow rates with faster completion of all tasks.
150 bar (15 MPa)combined with the machine's 75 L/min water flow, focuses on matching water volume with the cleaning and discharge task; it does not promise higher pressure or longer cleaning distance through a high flow rate.
Gasoline main unit, working hose, and adapter nozzle are selected according to the flushing task; surface flushing attachments are optional, and interfaces and operating conditions are confirmed separately

Continuous water supply, downstream discharge, and waste collection need to be judged as part of the same task.
Elbows, resistance, nozzles, and blockages will still change the propulsion and recovery conditions
Water replenishment, waste removal, and parking and organization also take time, and cannot be judged solely based on continuous spraying for a period.
75 L/min total water supply, the continuous water supply and waste collection should be prioritized in the selection. Specific configurations still need to be combined with the machine's documentation, pipeline conditions, and trial operation to confirm.

|---|---|---|
| Continuous flushing and discharge task | Stable water source, silt, and downstream discharge. | First determine whether the water supply and waste disposal can be coordinated, then arrange for segmented operations. |
| Piping between inspection wells | Well distance, elbows and hose retrieval conditions | The effective distance is affected by the hose resistance and the working attachment, and cannot be directly estimated based on flow rate. |
| Multi-point outdoor maintenance | Fuel, water replenishment, and waste removal. | Include the supply, transition, and wrap-up phases into the shift, and do not use the overall machine value to replace the on-site output. |
| Comparison between 55 and 75 L/min | Actual water source, waste material, and complete task | Comparing the same pipeline conditions and finishing requirements, a larger water volume does not directly prove lower costs. |
| Clean pipe diameter and inlet | Clear pipe bore, pipe material, narrowest access point and bends | Provide dimensions or a pipeline diagram to determine whether the nozzle and working pipe can enter, bend, and safely retrieve. |

First determine whether the water supply and waste disposal can be coordinated, then arrange for segmented operations.

Outdoor site arrangement: first confirm fuel, water supply, cleaning materials, and nozzles, and separate pipe tasks from surface rinsing.

Combine the on-site waste, working attachment, and water supply and drainage arrangements, with specific results observed through same-condition trial runs.
Pressure indication, overall flow, and power should be compared; working pressure, maximum pressure, and allowable operating conditions also need to be verified against the corresponding technical data.

Flow rate is not a guarantee for the diameter or distance of the pipe that can be cleared. Actual progress, flushing, and operation time are also affected by the pipeline, nozzle, water supply, and blockages.

The left figure shows the overall appearance of this model, with six items indicating functional descriptions; do not misrepresent general descriptions as internal structure diagrams.
Park the main unit according to the outdoor point arrangement and move it for transfer, leaving space for the hose entry and exit and on-site passage.
The gasoline-powered model is convenient for moving between locations without fixed power sources; water supply, fuel, and exhaust conditions should be implemented simultaneously.
A machine flow rate of 75 L/min needs a continuous water supply. Check the pump type and allowable operating conditions in the documentation for the machine.
Maintain records of continuous water supply and usage of the nozzle, and check the inlet, working hose, and connections as per the instructions. Do not assume component compatibility based on the overall machine flow.
Select an appropriate nozzle based on the pipe material, blockage type, and inlet; arrange the advancement, retraction, and direction of the waste together.
Rolling, retrieving, and parking the hose according to the machine's configuration, record the condition of the working hose and fittings after cleaning.
Look at the direction of clean water flow and waste matter, then determine how to coordinate with your pipeline. This is a general jetting process explanation. Specific operations are carried out according to the machine's manual and training.
The gasoline engine drives the pump unit, which pressurizes the incoming water and sends it to the working hose. The main unit is arranged in an open outdoor area, with fuel and continuous water supply prepared.
The water is delivered to the jetting nozzle via the work hose; the length, bend, and connection conditions affect the end conditions, and the hose length is not equal to the effective jetting distance.
Match the nozzle with the piping according to the continuous flushing task, and the overall machine flow does not represent that each working attachment can reach the maximum at the same time.
Continuous flushing and discharge require synchronized scheduling of water source, downstream discharge, and waste collection, combined with segmented treatment at inspection wells to avoid re-depositing waste downstream.
First, clarify the pipeline and waste, then match the working hose, jetting nozzle, and water supply and drainage. Whether the accessories are standard and their specific specifications are subject to the delivery list of this model.
150 bar (15 MPa) combined with a 75 L/min water flow focuses on matching water volume with the cleaning and discharge tasks; it is not about using a high flow rate to promise higher pressure or longer cleaning distance. The pressure and hose diameter should be based on the machine's specifications, and the maximum pressure cannot be considered as the continuous working pressure.
Pipe diameter limits nozzle size and clearance. Assess pipe length together with bends and access points. The hose length in the machine specification alone does not establish how far a blockage can be cleared.
Distinguish between oil, loose sand, and hard objects blocking; select separately the internal spray nozzles and surface cleaning attachments, and check the hole size, interface, and pressure according to the specifications of this machine.
| What does the customer provide? | What needs to be matched | How to make a selection and judgment? |
|---|---|---|
| Clear pipe diameter, inlet, and elbow | Nozzle outer diameter, working pipe and connection form | Verify whether it can enter, turn, and retrieve, not only comparing the cleaning pressure. |
| Oil, sand, or other blockages | Nozzle spray form, pressure flow and pipe material resistance | First, distinguish between soft, removable debris that can be flushed and hard objects or blockages that require separate handling. |
| Total length of the pipeline and distance between the two wells. | Working hose length, hose winding and segment position. | The length is determined based on the actual delivery, combined with the end conditions, and no fixed effective distance is promised. |
| Pipe jetting or auxiliary surface cleaning. | Specialized pipe jetter nozzle or corresponding cleaning attachment | Two types of tasks should be checked separately against the interface, operating conditions, and delivery list; no conclusion can be drawn from the display images regarding the standard configuration. |


First, check the pipeline task, then compare the power and pressure ratings and water volume. Boundary models use task or power references, which do not necessarily mean the left or right model is smaller or larger.

Pressure diameter, flow test conditions, and specific configuration need to be confirmed separately; they should not be based on the highest numerical promise for applicable pipe diameter, distance, or shift output.
Treat continuous flushing as a specific task and count it according to the four stages: preparation, operation, resupply, and conclusion.
Focus on recording water supply preparation, actual flushing and discharge, water replenishment waiting, and wastewater transportation, evaluating the complete task without committing to a lower single cost.
Record the amount of gasoline, actual water used, wear and tear of the work hose and nozzle, daily maintenance, and waste disposal separately.
Compare the same pipeline, same completion requirements, and same cycle. Procurement costs and depreciation allocation are not added redundantly, and no preset savings ratio or payback period is assumed.
Specific steps, maintenance cycles, and disassembly requirements shall be followed according to the machine's manual and training, and the web is not to be used instead of the maintenance manual.
Stable water source, silt, and downstream discharge are key factors. After the task changes, re-evaluate and do not follow the previous on-site conclusion.
Maintain records of continuous water supply and usage of the nozzle, and check the inlet, working hose, and connections as per the instructions. Do not assume component compatibility based on the overall machine flow.
Record the type of pipe material, the type of blockage, and the type of nozzle used, and inspect for visible damage; the cleaning method should be carried out according to the machine's instructions.
Check and maintain the machine according to the gasoline power instructions. The maintenance cycle, fuel type, or electrical requirements cannot be applied to similar models.
Follow the machine training to organize the work hose, coil hose, and body, record abnormalities, and do not carry over unresolved faults into the next task.
Retain the model, configuration, operation time, and abnormal phenomena; after following the instructions to stop the machine, contact after-sales service, and do not attempt to disassemble the hose under pressure or modify the protection settings on your own.
Service scope, costs, and on-site arrangements are confirmed based on the actual project and agreement.
Check the equipment, configuration, and random documents together before delivery.
Combine the machine's working pipe, nozzle, and on-site conditions for understanding operations.
Bring the model number, pipeline conditions, and usage issues for communication.
Check the work hose, nozzle, fittings, and consumables against the machine version.
Service scope, costs, and arrival arrangements should be confirmed in advance.
Combine usage frequency, location, and actual agreement arrangements.
Bring in the specific pipeline conditions you are concerned about, and continue to communicate the specific configuration.
For outdoor flushing and drainage with a continuous water source and sewage collection conditions, focus on the machine's water capacity and downstream treatment. Do not equate high flow rates with faster completion of all tasks. Specific applicability still depends on the pipeline, blockage conditions, and site conditions, and is not guaranteed by the model name.
At 150 bar (15 MPa) and a total flow of 75 L/min, compare the water available with the flushing task. Flow alone cannot establish pressure or reach. Verify the stated rating, maximum pressure and continuous operating range separately. The type of blockage also determines what the jet can clear.
First, check the well spacing, sediment in the pipes, and the smoothness of the downstream flow to arrange the feeding and retrieval of the hose and the collection of wastewater; do not directly convert the total water volume of the machine to effective distance.
Gasoline internal combustion engines are not used in indoor or semi-enclosed spaces; even in open outdoor areas, exhaust, fuel, fire sources, water supply, and drainage must be arranged according to the instructions.
No. A spray bar, rotary head or surface cleaner can be specified for the job. Check the nozzle, connection and operating range for each tool, and confirm the supplied accessories on the order.
75 L/min is the overall flow rate of this machine. Continuous water supply, nozzle, pipeline, and drainage will affect the operation, and cannot be directly converted into single gun output, processing distance, or fixed efficiency.
Keep the original manual and configuration sheet. Check the water source, working hose, nozzle, fittings, coiled hose, and power status according to the instructions. Do not use cycle, oil type, and disassembly information from other models.
First, follow the machine's instructions to shut down and handle the machine. Record the water supply, nozzle, pipeline, and any abnormal phenomena, then contact after-sales service. Do not disconnect the pipe without pressure, and do not adjust the safety valve setting on your own or force the pipeline to be sent.

First discuss the actual pipeline of continuous flushing tasks, then organize the stable water source, silt, and downstream discharge with daily work schedule together.
