When using this product basic precautions
should always be followed, including the
following:
1 Read all the instructions before using
the product.
2 High pressure jets can be dangerous if
misused. The jet must not be directed at
persons, animals, electrical devices, or
the unit itself.
3 To reduce the risk of injury, close super-
vision is necessary when a product is
used near children.
4 Know how to stop the product and
bleed pressures quickly. Be thoroughly
familiar with the controls.
5 Stay alert – watch what you are doing.
6 Wear safety goggles.
7 Do not use acids, alkaline, solvents, or
any flammable material in this product.
These products can cause physical in-
juries to the operator and irreversible
damage to the machine.
8 Do not operate the product when fa-
tigued or under the influence of alcohol
or drugs.
9 Do not overreach or stand on unstable
support. Keep good footing and bal-
ance at all times.
10 To reduce the risk of electrocution,
keep all connections dry and off the
ground. Do not touch plug with wet
hands.
11 The Trigger Gun Safety Lock prevents
the trigger from accidentally being en-
gaged. This safety feature DOES NOT
lock trigger in the ON position.
12 Keep operating area clear of all per-
sons.
13 Close cover before operating the ma-
chine.
14 This appliance is intended for commer-
cial use.
15 Follow the maintenance instructions
specified in the manual.
16 This 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.
17 This 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.
18 Do 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
1200 psi/8.3 MPa. To avoid rupture and
injury, do not operate this pump with
components rated less than 1200 psi/
8.3 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.
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 empha-
sized and understood.
4EN
– 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
몇 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.
Always connect the system separator to
the water supply, never directly to the appliance!
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 1/2 inch
in diameter.
– Flow rate of water supply must not fall
below 2.5 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.
SAVE THESE INSTRUCTIONS!
5EN
Please read and comply with
these original instructions prior
to the initial operation of your appliance and

– Before first start-up it is definitely nec-
essary to read the operating instructions and safety indications Nr. 5.951-
949.0!
– In case of transport damage inform ven-
dor immediately
– Check the contents of the pack before
unpacking.

completely
Safety instructions
몇 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 deficien-
cies (cold, numb fingers).
– 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.
– 4
9EN
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.
