IMPORTANT SAFETY INSTRUCTIONS
WARNING
When using this product basic precautions should always be followed, including the following:
1Read all the instructions before using the product.
2High pressure jets can be dangerous if misused. The jet must not be directed at persons, animals, electrical devices, or the unit itself.
3To reduce the risk of injury, close supervision is necessary when a product is used near children.
4Know how to stop the product and bleed pressures quickly. Be thoroughly familiar with the controls.
5Stay alert – watch what you are doing.
6Wear safety goggles.
7Do not use acids, alkaline, solvents, or any flammable material in this product. These products can cause physical injuries to the operator and irreversible damage to the machine.
8Do not operate the product when fatigued or under the influence of alcohol or drugs.
9Do not overreach or stand on unstable support. Keep good footing and balance at all times.
10To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch plug with wet hands.
11The Trigger Gun Safety Lock prevents the trigger from accidentally being engaged. This safety feature DOES NOT lock trigger in the ON position.
12Keep operating area clear of all persons.
13Close cover before operating the machine.
14This appliance is intended for commercial use.
15Follow the maintenance instructions specified in the manual.
16This machine has been designed for use with cleaning chemicals supplied or recommended by the manufacturer. The use of other cleaning chemicals may affect the operation of the machine and void the warranty.
17This product is provided with a Ground Fault Circuit Interrupter built into the power cord plug. If replacement of the plug or cord is needed, use only identical replacement parts.
18Do not use extension cord with this product.
–Injection hazard: equipment can cause serious injury if the spray penetrates the skin. Do not point the gun at anyone or any part of the body. In case of penetration seek medical aid immediately.
–This system is capable of producing 2000 psi/13.7 MPa.
To avoid rupture and injury, do not operate this pump with components rated less than 2000 psi/13.7 MPa working pressure (including but not limited to spray guns, hose and hose connections).
–Before servicing, cleaning, or removal of any part, shut off power and relieve pressure.
–Do not spray electrical apparatus and wiring.
–High Pressure. Keep clear of nozzle.
–If connection is made to a potable water system, the system shall be protected against backflow.

EN |
Owner/User Responsibility
–The owner and/or user must have an understanding of the manufacturer’s operating instructions and warnings before using this pressure washer.
–Warning information should be emphasized and understood.
–If the operator is not fluent in English, the manufacturer’s instructions and warnings shall be read to and discussed with the operator in the operator’s native language by the purchaser/ owner, making sure that the operator comprehends its contents.
–Owner and/or user must study and maintain for future reference the manufacturers’ instructions.
GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
DANGER
Improper connection of the equipmentgrounding conductor can result in a risk of electrocution. Check with a qualified electrician or service personnel if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the product - if it will not fit the outlet, have a proper outlet installed by a qualified electrician. Do not use any type of adapter with this product.
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
This product is supplied with a Ground Fault Circuit Interrupter (GFCI) built into the power cord plug. This device provides additional protection from the risk of electric shock. If power is interrupted in the line, the GFCI will automatically re-close the circuit to the load after power is restored. Depending on the GFCI model, it may be necessary to manually operate the reset button to restore power to the GFCI load circuit. If replacement of the plug or cord is needed use identical replacement parts.
WATER SUPPLY
CAUTION
When connecting the water inlet to the water supply mains, local regulations of your water company must be observed. In some areas the unit must not be connected directly to the public drinking water supply. This is to ensure that there is no feedback of chemicals into the water supply. Direct connection via a receiver tank or backflow preventer, for example, is permitted.
Dirt in the feed water will damage the unit. To avoid this risk, we recommend fitting a water filter.
–Garden hose must be at least 3/4 inch in diameter.
–Flow rate of water supply must not fall below 4.0 GPM (gallons per minute).
–Flow rate can be determined by running the water for one minute into an empty 5-gallon container.
–The water supply temperature must not exceed 86°F/30°C.
–Never use the pressure washer to draw in water contaminated with solvents, e.g. paint thinners, gasoline, oil, etc.
–Always prevent debris from being drawn into the unit by using a clean water source. Use additional water filter.
SAVE THESE INSTRUCTIONS!

Safety Devices
Safety devices serve for the protection of the user and must not be put out of operation or bypassed with respect to their function.
Overflow valve with two pressure switches
–While reducing the water supply at the pump head or with the Servopress - regulation the overflow valve opens and part of the water flows back to the pump suck side.
–If the hand-spray gun is closed, so that the whole water flows back to the pump suck side, the pressure switch at the overflow valve shuts down the pump.
–If the hand spray gun is opened, the pressure switch on the cylinder head turns the pump back on.
The overflow valve is set by the manufacturer and sealed. Setting only by customer service.
Safety valve
–The safety valve opens, when the overflow valve resp. the pressure switch is broken.
The safety valve is set by the manufacturer and sealed. Setting only by customer service.
Water shortage safeguard
–The water shortage safeguard prevents the burner to be turned on when there is water shortage.
–A sieve prevents the contamination of the safeguard and must be cleaned regular.
Temperature stop for exhaust gases
–The temperature stop switches off the machine when the waste gases have reached very high temperatures.

Safety instructions
Warning
Long hours of using the appliance can cause circulation problems in the hands on account of vibrations.
It is not possible to specify a generally valid operation time, since this depends on several factors:
–Proneness to blood circulation deficiencies (cold, numb fingers).
12 |
EN – 5 |
–Low ambient temperature. Wear warm gloves to protect hands.
–A firm grip impedes blood circulation.
–Continuous operation is worse than an operation interrupted by pauses.
In case of regular, long-term operation of the device and in case of repeated occurrence of the symptoms (e.g. cold, numb fingers) please consult a physician.
Replace the nozzle
Danger
Switch the appliance off prior to replacing nozzle and activate hand spray gun until device is pressureless.
