Owner/User Responsibility
The owner and/or user must have an
understanding of the manufacturer’s
operating instructions and warnings be-
fore using this pressure washer.
Warning information should be empha-
sized and understood.
If the operator is not fluent in English,
the manufacturer’s instructions and
warnings shall be read to and dis-
cussed with the operator in the opera-
tor’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 manu-
facturers’ 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 IN-
TERRUPTER 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 5 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.

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 over-
flow 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.
