IMPORTANT PRECAUTIONS – Read First!

Safety Warnings

When using this product, basic precau­tions should always be followed:

• Read all the instructions before using
the product.

• 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.

• To reduce the risk of injury, do not
operate the machine near children.

• Learn how to stop the machine and
release pressure quickly. Be thoroughly
familiar with the controls.

• Stay alert — watch what you are doing.

• Wear safety goggles.

• Do not use acids,
solvents, or any
flammable material in this product.
These products can cause physical
injuries to the operator and irreversible
damage to the machine.

• Do not operate the product when
fatigued or under the influence of
alcohol or drugs.

• Keep operating area clear of all
persons.

• Do not stand on unstable surfaces.
Stand with both feet balanced at all
times.

• To reduce the risk of electrocution, keep
all connections dry and off the ground.
Do not touch plug with wet hands.

• The Gun Safety Lock PREVENTS
the trigger from accidentally being
engaged. This safety feature DOES
NOT lock trigger in the on position.

Extension Cords

Use a sufficient gauge: Up to 25 ft = 12/3
AWG; 25 to 50 ft = 10/3 AWG. Use only
extension cords that are intended for
outdoor use. These extension cords are
identified by the marking “Acceptable for
use with outdoor appliances; store indoors
while not in use.” Use only extension
cords having an electrical rating not less
than the rating of the product. Do not use
damaged extension cords. Examine
extension cord 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. If you are using an
extension cord, it should always be
completely unwound from the cable drum.

Ground Fault Circuit
Interrupter (GFCI) 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 re­close 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.

This Product Is
Double Insulated

In a double-insulated product, two
systems of insulation are provided instead
of grounding. No grounding method is
provided on a double-insulated product,
nor should a method for grounding be
added to the product. Servicing a double­insulated product requires extreme care
and knowledge of the system, and should
be done only by qualified service
personnel. Replacement parts for a
double-insulated product must be
identical to the parts they replace. A

double-insulated product is marked with
the words, “DOUBLE INSULATED.”

Caution

• Follow the maintenance instruc­tions specified in the manual.

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