ment of the plug or cord is needed,
use only identical replacement parts.
ADVERTENCIA
Risk of Injection or Injury – Do Not
Direct Discharge Stream At Persons.
High pressure jets can be dangerous
if misused. The jet must not be di-
rected at persons, animals, electrical
devices, or the unit itself.
Wear safety goggles.
WARNING
Risk Of Explosion – Do not spray
flammable liquids.
Do not use acids, alkaline, solvents,

몇CAUTION
This unit has been designed for use with
cleaning detergents recommended by
the manufacturer. The use of other
cleaning detergents may affect the oper-
ation of the machine and void the war-
ranty.
몇CAUTION

TURE AND INJURY, DO NOT
OPERATE THIS PUMP WITH COM-
PONENTS RATED LESS THAN 1800
PSI WORKING PRESSURE (INCLUD-
ING BUT NOT LIMITED TO SPRAY
GUNS, HOSE AND HOSE CONNEC-
TIONS).
BEFORE SERVICING, CLEANING OR
REMOVING ANY PARTS, SHUT OFF
POWER AND RELIEVE PRESSURE.
IF CONNECTION IS MADE TO A PO-
TABLE WATER SYSTEM, THE SYS-
TEM SHALL BE PROTECTED
AGAINST BACK FLOW.
This product must be grounded. If it
should malfunction or breakdown,
grounding provides a path of least resis-
tance for electric current to reduce the
risk of electric shock. This product is
equipped with a cord having an equip-
ment-grounding conductor and a ground-
ing plug. The plug must be plugged into
an appropriate outlet that is properly in-
stalled and grounded in accordance with
all local codes and ordinances.
DANGER
Improper connection of the equipment-
grounding 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 prop-
erly 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.
This pressure washer is provided with a
ground-fault circuit-interrupter (GFCI)
built into the plug of the power-supply
cord. This device provides additional
protection from the risk of electric shock.
Should replacement of the plug or cord
become necessary, use only identical
replacement parts that include GFCI
protection.
몇CAUTION
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 con-
nected directly to the public drinking wa-
ter 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 13 mm
or 16 mm (1/2 inch or 5/8) inch in di-
ameter.
Flow rate of water supply must not
fall below 7.6 L/min. (2 GPM/gallons
per minute).
Flow rate can be determined by run-
ning the water for one minute into an
empty 20 litre (5-gallon) container.
The water supply temperature must
not exceed 40°C/104°F.
Never use the pressure washer to
draw in water contaminated with sol-
vents, e.g. paint thinners, gasoline,
oil, etc.
Always prevent debris from being
drawn into the unit by using a clean
water source.

To clean at maximum pressure, the
wand must be positioned to the high
pressure setting (Max).
For lower pressure turn the wand col-
lar in the minus (Min) direction.
To apply detergent, the wand must
be positioned to the lower pressure
setting (Mix).
This nozzle features a 0º pencil jet
which rotates 360º for maximum dirt
cutting action, effectively increasing

INSTRUCCIONES IMPORTANTES DE SEGURIDAD

20 Español
Este producto se tiene que poner a tie-
rra. Si funcionase mal o si se rompiese,
la puesta a tierra proporcionaría una cir-
cuito menos resistente a la energía
eléctrica para reducir el riesgo de elec-
trochoque. Este producto está equipado
con un cable que tiene un conductor a
tierra y un enchufe a tierra para el equi-
po. El enchufe se tiene que enchufar a
un tomacorriente adecuado, que esté
correctamente instalado y puesto a tie-
rra conforme a todas las normas y regla-
mentos locales.
PELIGRO
Si la conexión del conductor a tierra del
equipo es incorrecta puede existir ries-
go de electrochoque. En caso de duda,
compruebe con ayuda de un electricista
cualificado o del personal del servicio
técnico que el tomacorriente está co-
rrectamente puesto a tierra. No modifi-
que el enchufe proporcionado con el
producto; si no encaja en el tomaco-
rriente, pida a un electricista cualificado
que le instale un tomacorriente adecua-
do. No utilice ningún tipo de adaptador
con este producto.
Este producto se suministra con un inte-
rruptor de circuito de avería por puesta
a tierra montado en el enchufe del cable
de potencia. Este aparato proporciona
una protección adicional contra el riesgo
de electrochoque. Si es necesario
reemplazar el enchufe o el cable, utilice
piezas idénticas.
ATENCIÓN
Al conectar la toma de agua a la red de
suministro del agua, es obligatorio res-
petar la normativa local establecida por
la compañía del agua. En algunas zo-
nas, está prohibido conectar la unidad
directamente a la red pública de sumi-
nistro de agua potable. Esto es así para
garantizar que no penetren sustancias
químicas en la red de suministro del
agua. Sí se permite efectuar la conexión
directamente por ejemplo a través de un
depósito receptor o un dispositivo anti-
rretorno.
Si el agua de alimentación está sucia, la
unidad sufrirá daños. Para evitar este
riesgo, le recomendamos que monte un
filtro de agua.
La manguera de agua tiene que te-
ner al menos 1/2“ (13 mm) pulgadas
de diámetro.
El caudal de agua no debe ser infe-
rior a 450 l/h (litros por hora).
El caudal de agua se puede determi-
nar llenando de agua un recipiente
vacío de 8 litros durante un minuto.
La temperatura de la toma de agua
no debe sobrepasar los 104°F/40°C.
No utilice nunca el limpiador a pre-
sión para aspirar agua contaminada
con disolventes como, p. ej., diluyen-
tes de pintura, gasolina, aceite, etc.
Evite siempre que la unidad aspire
residuos utilizando una fuente de
abastecimiento cuya agua esté lim-
pia.
