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
other 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.

• 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 = 12/2
AWG; 25 to 50 ft = 10/2 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 Protection

To comply with the National Electrical
Code (NFPA70) and to provide additional
protection from the risk of electrocution,
this high pressure washer should only be
connected to a receptacle that is protect­ed by a ground fault circuit interrupter
(GFCI). For best results, unit should be
plugged into an unshared outlet.

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 double-insu­lated 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.

You will need a standard screw driver OR a Torx T-25 screw driver

Step 3 Slide the spray wand extension into

the gun. Turn the wand collar onto the gun
threads until tight.
