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 the manufacturers’ instructions for future reference.

This device must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

This device is equipped with a cord having an equipment grounding conductor and ground plug.

The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

This appliance 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 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.

When connecting the water inlet with 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 1 inch in diameter.

• Flow rate of water supply must not fall below 4 GPM (gallons per minute).

• Flow rate can be determined by running the water for one minute into an empty 4-gallon container.

• The water temperature must not exceed 140° F/60° 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.

The high-pressure cleaner with high-pressure jet is intended only for the cleaning of objects, including:

• Machines, vehicles, structures, tools, walls, patios and garden equipment.

The following limit values apply to the water supply:

• pH value: 6.5-9.5

• Electrical conductivity: Conductivity of fresh water + 1200 µS/cm, maximum conductivity 2000 µS/cm

• Settleable particles (sample volume 1 l, settling time 30 minutes): < 0.5 mg/l

• Filterable particles: < 50 mg/l, no abrasive substances

• Hydrocarbons: < 20 mg/l

• Chloride: < 300 mg/l

• Sulfate: < 240 mg/l

• Calcium: < 200 mg/l

• Total hardness: < 28 °dH, < 50° TH, < 500 ppm (mg CaCO₃/l)

• Iron: < 0.5 mg/l

• Manganese: < 0.05 mg/l

• Copper: < 2 mg/l

• Active chloride: < 0.3 mg/l

• Free of unpleasant odors

The power switch stops you from operating the device unintentionally.

The lock blocks the lever of the high-pressure gun and prevents the device from starting unintentionally.

If the lever on the high-pressure gun is released, the pressure switch switches the pump off and the high-pressure jet stops. If the lever is pressed, the pump switches on again.

The motor circuit breaker shuts off the device if power consumption is too high.

The overflow valve prevents the permissible working pressure from being exceeded. If the lever on the trigger gun is released the pressure switch turns off the pump, the high pressure jet is stopped. If the lever is pulled the pump is turned on again.

This appliance 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 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.
