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.

GROUND FAULT CIRCUIT IN-
TERRUPTER PROTECTION
To comply with the National Electrical
Code (NFPA 70) and to provide additional protection from the risk of electric
shock, this pressure washer should
only be connected to a receptacle that
is protected by a ground fault circuit interrupter (GFCI).
EXTENSION CORDS
Use only 3-wire extension cords that
have 3-prong grounding-type plugs
and 3-pole cord connectors that accept
the plug from the product. Use only extension cords that are intended for outdoor use. These extension cords are
identified by a marking "Acceptable for
use with out-door appliances: store indoors while not in use." Use only extension cords having an electrical
rating not less than the rating of the

before using and replace if damaged.
Do not abuse extension cord and do
not yank on any cord to disconnect.
Keep cord away from heat and sharp
edges. Always disconnect the extension cord from the receptacle before
disconnecting the product from the extension cord.
몇 Warning
To reduce the risk of electrocution,
keep all connections dry and off the
ground. Do not touch plug with wet
hands.
몇 Warning
To reduce the risk of fire, electric
shock, or injury:
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
25000 kPa. To avoid rupture and injury, do not operate this pump with components rated less than 25000 kPa
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.
High Pressure. Keep clear of nozzle.
Close cover before operating the machine.
This appliance is intended for commercial use.
Do not spray electrical apparatus and
wiring.

SAVE THESE INSTRUCTIONS
WATER SUPPLY
(Cold Water Only)
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.

Dirt in the feed water will damage the
unit. To avoid this risk, we recommend
fitting a water filter.
– Never use the pressure washer to
draw in water contaminated with
solvents, e.g. paint thinners, gaso-
line, oil, etc.
– Always prevent debris from being
drawn into the unit by using a clean
water source. Use additional water
filter.
Please read and comply with
these original instructions
prior to the initial operation of your appliance and store them for later use or

Proper use
Use this high pressure cleaner exclusively for
– Cleaning using low pressure jet and
detergent (for e.g. for cleaning machines, cars, buildings, tools),
– For cleaning using high pressure jet
without detergent (for e.g. for cleaning facades, terraces, garden appliances).
For stubborn dirt, we recommend the
use of the dirt blaster as a special accessory.
