ELECTRICAL
ELECTRICAL CONNECTION
This product has a precision-built electric motor. It should
be connected to a power supply that is volts,
50 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.
The cross-section of any extension cables used must be
proportional to their length, i.e. the longer the extension
cable, the greater the cross-section; cables with a
protection level of “IPX5” must be used.
Use the chart to determine the minimum wire size
required in an extension cord.

WARNING:
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.

Once a steady stream of water appears,release the
trigger.
NOTE: If the pressure washer pulsates and the water
stream is intermittent turn the pressure washer off and
continue to bleed air out of the system. Ensure to check
that the garden hose is fully turned on and not kinked
which could prevent air in the system and pulsating.
This process could take minimum of 120 seconds
or longer.

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.

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.
Soap is applied under low pressure high volume for
optimum performance. Soap cannot be applied under
high pressure with this machine.
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
