should be performed only by a qualied service technician. For service, we suggest you return the product to
your nearest authorized service center for repair. Always use original factory replacement parts when servicing.
ELECTRICAL CONNECTION
This product has a precision-built electric motor. It should be connected to a power supply that
is 120 volts, 60 Hz, AC only (normal household current). 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.
EXTENSION CORDS (
See Figure 1.)
When using a power tool at a considerable distance from a power source, be sure to use an
extension cord that has the capacity to handle the current the product will draw. An undersized
cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to
determine the minimum wire size required in an extension cord. Only round jacketed cords listed
by Underwriter’s Laboratories (UL) should be used. When working outdoors with a product, use
an extension cord that is designed for outside use.This type of cord is designated with “WA” or “W”
on the cord’s jacket. Before using any extension cord, inspect it for loose or exposed wires and
cut or worn insulation. It is possible to tie the extension cord and power cord in a knot to prevent
them from becoming disconnected during use. Make the knot as shown in gure 1, then connect
the plug end of the power cord into the receptacle end of the extension cord. This method can
also be used to tie two extension cords together..
WARNING
The double insulated system is intended to protect the user from shock resulting from a break in
the product’s internal insulation. Observe all normal safety precautions to avoid electrical shock.
DOUBLE INSULATED
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.

Keep the extension 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
Check extension cords before each use. If damaged replace immediately. Never use the product
with a damaged cord since touching the damaged area could cause electrical shock resulting in
serious injury.
GROUND FAULT CIRCUIT INTERRUPTER
This unit is equipped with a Ground Fault Circuit Interrupter (GFCI), which guards against the
hazards of ground fault currents. An example of ground fault current is the current that would
ow through a person who is using an appliance with faulty insulation and, at the same time, is in
contact with an electrical ground such as a plumbing xture, wet oor, or earth.
GFCI plugs do not protect against short circuits, overloads, or shocks.
NOTE: To ensure readiness for use, press the reset button each time you connect the pressure washer to the
power supply
