Safety Warnings

When using this product basic 
precautions should always be followed:

• Read all the instructions before using the

product.

FIRE HAZARD!

Do not add fuel with the

engine running. Do not operate if fuel has
been spilled. Instead move the machine
to a different location and avoid creating
sparks. 

• Operate and fuel machine in a well venti-

lated area, free of devices featuring an
open pilot or flame such as boilers, water
heaters, etc.

• High pressure jets can be dangerous 

if subject to misuse. The jet must not 
be directed at persons, animals, electrical
devices, or the machine itself.

• Wear safety goggles.

• Do not use acids, solvents, or any other

flammable material in this product. These
products can cause physical injuries to
the operator and irreversible damage to
the machine.

• The machine has hot surfaces which can

cause burns. Operate the unit in a safe
environment and away from children.

• Do not allow the high pressure hose to 

come into contact with the muffler guard.

• Do not leave the machine running 

unattended.

• Learn how to stop the machine and

release pressure quickly. Be thoroughly
familiar with the controls.

• Stay alert — watch what you are doing.

• Do not operate the product when fatigued

or under the influence of alcohol or drugs.

• Do not stand on unstable surfaces. Stand

with both feet balanced at all times.

• The Gun Safety Lock PREVENTS the

trigger from accidentally being engaged.
This safety feature DOES NOT lock trigger
in the on position.

Water Supply
(Cold Water Only)

• Water hose must be at least 3/4 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 104°F/40°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. 

We strongly recommend that this high
pressure washer not be left running for
periods of 5 minutes or longer without
the trigger gun being engaged.

This Kärcher high pressure washer is
equipped with thermal protection to
extend the life of your pressure washer.
The thermal protector will automatically
activate at a predetermined high temper-
ature ejecting hot water before resetting.
This ensures that the pump does not
become damaged.

tions specified in the manual.

• This machine has been designed

for use with cleaning detergent
supplied or recommended by the
