Water Supply
(Cold Water Only)
Gun kicks back – Hold with both hands
The trigger gun safety lock prevents
the trigger from accidentally being
engaged. This safety feature must be
engaged when replacing nozzles or
not in use.
The engine exhaust from this product
contains chemicals known to the State
of California to cause cancer, birth
defects or other reproductive harm.
Operation of this equipment may
create sparks that can start fires
around dry vegetation. A spark arrestor
may be required. Operator should
contact local fire agencies for laws or
regulations.
Risk of asphyxiation – Use this product
only in a well ventilated area. Do not
operate indoors or in any confined
area.
Operate and fuel machine in a well
ventilated area, free of devices featur-
ing an open pilot or flame such as
boilers, water heaters, etc.
Risk of fire/explosion – Do not add fuel
when the machine is operating or still
hot.
Risk of fire/explosion -Operate only
where open flame or torch is permitted.
Do not spray flammable liquids.
Do not operate if fuel has been
spilled. Instead, move machine to
different location and avoid creat-
ing sparks.
This machine has hot surfaces
which can cause burns. Operate

Do not touch hot surfaces or allow
accessories to contact hot surfac-
es.
Do not leave machine running
unattended.
Avoid tipping machine on its side.
When connecting to water supply
mains, local regulations of your
municipal water company must be
observed. In some areas connect-
ing directly to public drinking water
supply may require a back flow
prevention device. This is to
ensure that there is no feedback
of chemicals into the water supply.
Use a water filter to avoid potential
damage from dirt in the water
supply.
Garden hose must be at least 5/8
inch diameter.
Flow rate of water supply must not
fall below 2.6 GPM(gallons per
minute)
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 122°F/50°C.
Never use the pressure washer to

this can cause engine damage.
Turn the oil gauge dipstick counter
clockwise; remove it and clean it with a
clean cloth.
Fully reinsert the oil gauge dipstick and
pull it out to check the oil level.
If the oil level is halfway up the dipstick
or below, refill with SAE
10W -30 oil through the dipstick hole
until the oil level reaches 3/4 up the
dipstick or until it reaches the bottom
lip of the dipstick hole as shown.

nozzles provide a wide array of spray
widths from 0° to 40° and are easily
accessible when placed in the conve-
nient nozzle holder.
0° spray angle = Red nozzle

ing with low pressure.
High pressure in nozzle area. Risk of
injury caused by improperly locked
nozzle.
Make sure you hear the "click" when
inserting the nozzle tip into the quick
connection.
Pull the nozzle to make sure it is
seated properly before operating your
unit.
To avoid serious injury never point

or animals.
Detergents can only be applied with
the black detergent nozzle.
Install the black detergent nozzle for
detergent application at low pressure.
Fill the detergent tank with Detergent.
With the engine running, pull trigger to
operate unit.
Liquid detergent is drawn into the unit
and mixed with water.
Apply detergent to work area.
Do not allow detergent to dry on
surface.
Always flush the detergent tank with
fresh water when the cleaning job is

detergents from the injection system.
NOTE: For best results see Cleaning
Tips for specific information on how to
clean different surfaces.
Never use:
Bleach, chlorine products or other
corrosive chemicals.
Liquids containing solvents (i.e., paint
thinners, gasoline, oils.)
Tri-sodium phosphate products.
Ammonia products.
Acid-based products.
These chemicals will harm the unit and
will damage the surface being
cleaned.
Use of these items will void the warran-
ty.
Move the engine stop switch to the
OFF position.
Release trigger and engage safety
lock.

holder assembly.
It is highly recommended to use a
small amount of antifreeze before
winter storage and during the cleaning
season to protect the pump from freez-
ing and premature wear.
Turn engine switch to the OFF position
Disconnect all hoses.
Unscrew cap from Pump Guard bottle.
Remove internal seal.
Reattach cap to Pump Guard bottle
and remove black protective cap.
Screw bottle into water inlet on pres-
sure washer pump and squeeze.
With ignition OFF, pull starter rope until

Cars, Boats& Motorcycles
Carry out maintenance tasks for the
engine according to the specifications
provided in the operating instructions
provided by engine manufacturer.
With or Without Detergent
Pre-rinse deck and surrounding area
with fresh water. For best results, limit
your work area to smaller sections of
approximately 25 square feet. Allow
Deck Wash 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.
With or Without Detergent
Pre-rinse vehicle with fresh water. For
best results, clean one side of vehicle
at a time and always apply detergent
from bottom to top, do not allow deter-
gent 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-strip-
ing 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.
With or Without Detergent
Pre-rinse cleaning surface with fresh
water.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.

high pressure in a sweeping motion
keeping the spray nozzle approximate-
ly 3-6 inches from the cleaning
surface. Always clean from top to
bottom and from left to right. For
removing extremely stubborn stains,
use a DirtBlaster® Spray Nozzle (sold
separately).
With or Without Detergent
Pre-rinse cleaning surface with fresh
water. Allow Pressure Wash 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.
With or Without Detergent
Pre-rinse furniture and surrounding
area with fresh water. If using Pressure
Wash, apply to surface at low pres-
sure. Allow Pressure Wash to remain
on surface 1-3 minutes. Do not allow
detergent to dry on surface. If needed

motion keeping the spray nozzle
approximately 3-6 inches from the
cleaning surface. For best results,
clean from top to bottom and from left
to right.
Before cleaning any surface, an incon-
spicuous 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 pres-
sure washer may remove the loose
paint from the surface.
When using on surfaces which might
come in contact with food, flush surfac-
es with plenty of drinking water.
