GROUNDING INSTRUCTIONS

This product must be grounded. If it
should malfunction or breakdown,
grounding provides a path of least re­sistance for electric current to reduce
the risk of electric shock. This product
is equipped with a cord having an
equipment-grounding conductor and a
grounding plug. The plug must be
plugged into an appropriate outlet that
is properly installed and grounded in
accordance with all local codes and or­dinances.

 DANGER

Improper connection of the equipment­grounding conductor can result in a
risk of electrocution. Check with a qual­ified electrician or service personnel if
you are in doubt as to whether the out­let is properly grounded. Do not modify
the plug provided with the product - if it
will not fit the outlet, have a proper out­let installed by a qualified electrician.
Do not use any type of adapter with this
product.

GROUND FAULT CIRCUIT IN-

TERRUPTER PROTECTION

CI) built into the plug of the power-sup­ply cord. This device provides
additional protection from the risk of
electric shock. Should replacement of
the plug or cord become necessary,
use only identical replacement parts
that include GFCI protection.

WATER SUPPLY

(Cold Water Only)

 CAUTION

When connecting the water inlet to the
water supply mains, local regulations
of your water company must be ob­served. In some areas the unit must
not be connected directly to the public
drinking water supply. This is to ensure
that there is no feedback of chemicals
into the water supply. Direct connec­tion via a receiver tank or backflow pre­venter, for example, is permitted.
Dirt in the feed water will damage the
unit. To avoid this risk, we recommend
fitting a water filter.

 Garden hose must be at least 1/2

inch or 5/8 inch in diameter.

 Flow rate of water supply must not

fall below 2 GPM (gallons per min-

ute).

 Flow rate can be determined by

running the water for one minute

into an empty 5-gallon container.

 The water supply temperature must

not exceed 104°F/40°C.

 Never use the pressure washer to

draw in water contaminated with

solvents, e.g. paint thinners, gaso-

line, oil, etc.

 Always prevent debris from being

drawn into the unit by using a clean

water source.

This nozzle combines the cleaning

performance of a 0º pencil jet with

the surface coverage of a wide an-

gle nozzle.

Not recommended for soft mate-

rials, siding, painted surfaces,

decks or autos.

CLEANING TIPS



CAUTION

 Before cleaning any surface an in-

conspicuous area should be
cleaned to test spray pattern and
distance for maximum cleaning re­sults.

 If painted surfaces are peeling or

chipping, use extreme caution as
pressure washer may remove the
loose paint from the surface.

 When using on surfaces which

might come in contact with food,
flush surfaces with plenty of drink­ing water.

Deck Cleaning

(with or without detergent). Pre-rinse

deck and surrounding area with fresh
water. If using detergent, apply to sur­face at low pressure. For best results,
limit your work area to smaller sections
of approximately 25 square feet. Allow
detergent to remain on surface 1-3
minutes. Do not allow detergent to dry
on surface. Rinse at high pressure in a
long sweeping motion keeping the
spray nozzle approximately 3-6 inches
from the cleaning surface. Always
clean from top to bottom and from left
to right. When moving on to a new sec­tion of the cleaning surface, be sure to
overlap the previous section to elimi­nate stop marks and ensure a more
even cleaning result.

House Siding

(with or without detergent). Pre-rinse

cleaning surface with fresh water. If us­ing detergent, apply to surface at low
pressure (for best results, limit your
work area to sections of approximately
6 feet and always apply detergent from
bottom to top). Allow detergent to re­main on surface 1-3 minutes. Do not
allow detergent to dry on surface, if
surface appears to be drying, simply
wet down surface with fresh water. If
needed, use special wash brush at­tachment (not included) to remove
stubborn dirt. Rinse at high pressure
from top to bottom in an even sweep­ing motion keeping the spray nozzle
approximately 6 inches from the clean­ing surface.

Cement Patios, Brick and Stone

(with or without detergent). Pre-rinse

cleaning surface with fresh water. If us­ing detergent or Degreaser, apply to
surface at low pressure. For best re­sults, limit your work area to smaller
sections of approximately 25 square
feet. Allow detergent or Degreaser to
remain on surface 1-3 minutes. Do not
allow detergent to dry on surface.
Rinse at high pressure in a sweeping
motion keeping the spray nozzle ap­proximately 3-6 inches from the clean­ing surface. Always clean from top to
bottom and from left to right. For re­moving extremely stubborn stains, use
the Dirtblaster ® Nozzle.

English 15

Cars, Boats & Motorcycles

(with or without detergent). Pre-rinse

vehicle with fresh water. If using deter­gent, apply to surface at low pressure.
For best results, clean one side of ve­hicle at a time and always apply deter­gent from bottom to top, do not allow
detergent to dry on surface. If needed,
use special wash brush attachment
(not included) to remove stubborn dirt.
Rinse at high pressure in a sweeping
motion keeping the spray nozzle ap­proximately 6-8 inches from the clean­ing surface (distance should increase
when rinsing pin-striping or other sen­sitive surfaces). Always clean from top
to bottom and from left to right. For best
results, wipe surface dry with a cham­ois or soft dry cloth.

Barbecue Grills, Outdoor Power

Equipment & Gardening Tools

(with or without detergent). Pre-rinse

cleaning surface with fresh water. If us­ing detergent or Degreaser, apply de­tergent at low pressure. Allow
detergent to remain on surface 1-3
minutes. Do not allow detergent to dry
on surface. Rinse at high pressure
keeping the spray nozzle approximate­ly 3-6 inches from the cleaning surface.
For removing extremely stubborn dirt,
it may be necessary to move the spray
nozzle even closer to the surface for
greater dirt cutting action.

Patio & Lawn Furniture
