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

ventilated 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,

alkalines, solvents, or
any 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.

• Avoid tipping the machine on its side.
• 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
temperature ejecting hot water before
resetting. This ensures that the pump does
not become damaged.

Caution

•  Follow the maintenance instructions

specified in the manual.

This machine has been designed
for use with cleaning detergents
supplied or recommended by the
manufacturer. The use of other
cleaning detergents may affect the
operation of the machine and void
the warranty.
