2. Depending on the need for hot and cold water:
High-pressure cleaner depending on the requirements of the occasion, can also be divided into hot water and cold water type. Most of the general market is cold water type, to the tap into the room temperature water can be used; but there are some places of business need to rinse with hot water, then you must especially buy hot water type of high-pressure cleaner, if you venture into the cold water type of hot water injection, the internal parts, including the pump will be damaged very quickly, the loss is not worth the gain.
The hot water cleaner is equipped with a heating device, which generally utilizes a combustion cylinder to heat the water. The use of hot water cleaning can quickly wash a lot of cold water is not easy to rinse dirt and grease, so that the cleaning efficiency has been greatly improved. But often because of the high price of hot water cleaner and high operating costs (because of the use of diesel fuel), most users may choose ordinary cold water high-pressure cleaner; of course, in order to improve the cleaning efficiency and effectiveness, there are still many professional customers will choose hot water cleaner.
3. But also choose the nozzle:
Different nozzles caused by the cleaning effect is different. Such as round water column nozzle can increase the cleaning efficiency, fan nozzle can be rotated nozzle as a low-pressure spray (can spray soapy water) and high-pressure fan water column, low-pressure brush head can spray low-pressure water gently scrubbing and so on. Some of these nozzles will come with a gift, some must be purchased on their own, in the purchase of reference to the needs of a good selection of it.
4. Select the business
There are many brands of cleaning machines on the market, imported ones are 1-2 times more expensive than the domestic ones, even more, and the choice should be based on your actual needs and budget. Usually imported equipment technology is new, its durability and efficiency than domestic have certain advantages, but its price is also much higher, maintenance costs are also higher than the domestic equipment to 2-3 times. After selecting the brand to use should also pay attention to the choice of business.
Maintenance
Routine maintenance - after each operation
1. Flush the hose and filter that accesses the detergent to remove any detergent residue to help prevent corrosion.
2. Turn off the water supply connected to the pressure washer.
3. Trigger the servo gun lever to relieve all pressure from the hose.
4. Remove the rubber hose and high pressure hose from the pressure washer.
5. Disconnect the spark plug connection wire to ensure the engine does not start (for engine models).
Electric Models:
Turn the power switch to the "on" and "off" position four to five times for 1-3 seconds each time to remove water from the pump. This step will help protect the pump from damage.
Engine Models:
Slowly pull the engine starter cord five times to remove water from the pump. This step will help protect the pump from damage.
Regular Maintenance - Every 2 Months
1. Regularly removing fuel deposits from the reservoir will extend the life and performance of the engine. Fuel deposits can cause damage to fuel lines, fuel filters and carburetors.
2. Protect your pressure washer with the K?rcher Pump Protection Kit (9.558-998.0) when not in use. The pump protection kit is specially designed to protect the pressure washer against corrosion, premature wear and freezing. And it's important to lubricate the valves and seals to prevent them from seizing.
Electric type:
1. Turn off the pressure washer.
2. Disconnect the high pressure hose and servo lance rod from the pump.
3. Connect the valve to the pump guard tank and open the valve.
4. Start and turn on the washer; draw all material in the tank into the pump.
5. Turn off the washer; the pressure washer can be stored directly.
Engine type:
1. Turn off the high pressure washer.
2. Disconnect the high pressure hose and servo lance rod from the pump.
3. Connect the valve to the pump guard tank and open the valve.
4. Turn on the ignition and pull the starter rope; draw all material in the tank into the pump.
5. The pressure washer can be stored directly.
Precautions
1- When operating the pressure washer: always wear appropriate goggles, gloves and mask.
2- Always keep hands and feet away from the cleaning nozzle.
3- Always check all electrical connections.
4- Always check all fluids.
5- Always check hoses for cracks and leaks.
6- Always leave the setting trigger in the safety lock position when the gun is not in use.
7- Always work with the lowest pressure possible, but one that will be sufficient to do the job.
8- Always relieve the pressure in the washer before disconnecting the hose.
9- Always drain the hose after each use.
10- Never point the spray gun at yourself or others.
11- Never start the unit until you have checked that all hose fittings are locked in place.
12- Never start the unit until the supply water is turned on and the proper amount of water is flowing through the gun barrel. Then attach the desired cleaning nozzle to the lance bar.
CAUTION: Do not leave the pressure washer running unsupervised. The pump will run in bypass mode each time you release the trigger. If a pump has been running in bypass mode for an extended period of time, the high temperature of the water circulating in the pump will shorten the life of the pump or even damage it. Therefore, avoid running the unit in bypass mode for long periods of time.
High-pressure rinsing equipment market analysis
Analysis of market survey results found that the high-pressure washing machine in the domestic market has a broad potential for development, in developed countries abroad, high-pressure rinsing machine has been a common use of the family, so that the market demand is very large, and there is a trend of continuous expansion. In the domestic market market research and analysis found that the domestic market for high-pressure rinsing machine should still be in the state of just starting, for the use of high-pressure rinsing is still very little, and is limited to the use of large and medium-sized enterprises. But with the rapid development of the economy, especially the rapid development of the automotive industry and the popularization of automobiles people live in the living environment gradually improved, and the quality of living environment, the domestic market for high-pressure flushing equipment is also increasing rapidly, the market demand is also increasing rapidly.
