ELECTRICAL
ELECTRICAL CONNECTION
This product has a precision-built electric motor. It should be connected to a power supply that
is 120 volts, AC only (normal household current), 60 Hz. Do not operate this product on direct
current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If
the product does not operate when plugged into an outlet, double-check the power supply.

ELECTRICAL
WARNING
Keep the cord clear of the working area. Position the cord so that it will not get caught on lumber,
tools, or other obstructions while you are working with a power tool. Failure to do so can result in
serious personal injury.
WARNING
Double insulation is a concept in safety in electric power tools, which eliminates the need for the
usual three-wire grounded power cord. All exposed metal parts are isolated from the internal
metal motor components with protecting insulation. Double insulated products do not need to be
grounded.

Nozzle
USING THE NOZZLES (See Figure 9.)
Each of the nozzles has a different spray pattern. Before starting any cleaning job, determine the
best nozzle for the job. The following chart offers some general guidelines to help you choose the
best nozzle for your application.
NOTE:
Red - Stream nozzle (0° )
 The Red 0 degree tip provides a straight line of spray. It provides the
highest amount of pressure. It is best used for removing hard, stuck-
on grime or dirt.
Green - Narrow fan tip (25° )
 The Green pressure washer tip provides high versatility with its 25
degree angle tip. Referred to as the washing tip, because it provides
adequate pressure to remove dirt from surfaces, but is designed to
not damage many surfaces. This pressure washer tip is designed for
“sweeping” foliage or debris given its wide angle. This tip is versatile
due to its wide area of cleaning and strong pressure application.

OPERATION
White - Wide fan tip (40° )
The white 40 degree tip, referred to as the “fan” tip creates the
widest area of cleaning with relatively low pressure. This pressure
washer tip is best used for light or delicate cleaning applications. It
is recommended for light cleaning on wood decks and other soft or
delicate surfaces.
Black - Soap nozzle tip
The black soap degree tip, referred to as the low pressure nozzle.
This is for use with soap application.
Turbo Nozzle Tip
The nozzle rotates in a zero to 15 degree spray pattern in a circular
motion to break down tough dirt and grime. The spray pattern can
cover area of 4 to 8 inches wide, depending on a distance between
the tip and the surface being cleaned.
