10. Watch your balance and footing while using your
power washer. Surfaces become slippery when wet
and are extra slippery when using a detergent or
cleaner.
11. NEVER operate the power washer in bare feet,
sandals, or open-toed shoes.
12. When using the power washer near children, make
sure they are closely supervised by an adult to avoid
injury. NEVER let a child use the power washer.
13. Keep fingers, hands, feet and any part of your body
clear of the stream of high pressure water. The
powerful spray can cause blindness or blast holes in
the skin. It can break a window if you are too close
when you pull the trigger on the spray gun.
14. ALWAYS wear eye protection to prevent injury to
eyes when operating the power washer.
15. To avoid mishaps or injury, ALWAYS use the trigger
safety lock when not using the power washer even
if the spraying stops for a moment.
16. The power washer is equipped with a Ground Fault
Circuit Interrupter (GFCI) which greatly reduces the
chance of electric shock while the unit is in use. If
replacement of the plug or cord is needed, use only
identical replacement parts.
17. Point the spray gun in a safe direction when
beginning a power washing session.
18. NEVER spray directly at a person, animal, electrical
device or the unit itself.
19. When first using the spray gun, hold the spray
gun and lance with two hands when pulling the
trigger (one hand to pull the trigger and the other
to stabilize the gun assembly) until you get used to
the “kickback” from the spray gun.
20. When you press the power switch to turn off the
power washer, water pressure may remain in the
system. To discharge the pressure, point the spray
gun in a safe direction and pull the trigger.
21. NEVER spray flammable liquids.
22. NEVER use the power washer in areas that contain
combustible dust, liquids or vapors.
23. Avoid contact of the pressure hose with sharp
objects and examine the hose regularly. Replace
if damaged. Due to the high pressure involved, it
cannot be repaired if cut or damaged.
24. Only use detergent specifically formulated for
power washers and follow instructions on the
detergent’s label.
25. Protect eyes, lungs, and skin from exposure to
detergent. Dish or laundry soap is too thick and will
clog the nozzle of your detergent bottle.
prevent the water in the unit from expanding under
freezing conditions. When the water freezes and
expands, your power washer will be damaged and
become inoperable. Or, if storing outdoors, it is
recommended you use pump saver (not included) to
protect pumps.
26. NEVER use hot water with your power washer. It
will overheat and damage the high pressure pump.
27. NEVER leave the power washer unattended while
it is powered “ON”.
28. ALWAYS turn the water supply “ON ” before
turning the power washer power to “ON”.
Running the pump dry will cause damage to the
internal components.
29. NEVER use a water supply to your power washer
that exceeds 150 PSI maximum.
30. NEVER disconnect the high pressure hose from the
power washer while the system is pressurized.
31. NEVER permanently engage the trigger
mechanisms on the spray gun.
32. NEVER operate the power washer unless all
components are properly and securely connected.
33. NEVER allow the power washer pump to run for
more than one minute after you have turned off
the water supply. This can cause the motor and
pump to overheat and fail.
34. NEVER use lances or other parts that are not
compatible for this specific AR Blue Clean unit.
35. NEVER use an extension power cord since it
defeats the effectiveness of the GFCI and increases
the chance of electrocuting the operator.
36. NEVER spray any electrical outlet with your power
washer.
37. Inspect the power cord before using. DO NOT use
it if it is damaged.
KEEP THESE INSTRUCTIONS FOR FUTURE REFERENCE.
Servicing of a Double-Insulated Appliance
Ground Fault Circuit Interrupter Protection:
This pressure washer is provided with a ground-fault
circuit-interrupter (GFCI) built into the plugs 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.
In a double-insulated product, two systems of
insulation
are provided instead of grounding. Grounding means
are not provided for a double insulated product, nor
should grounding means be added to the product.
Servicing a double-insulated product requires extreme
care and knowledge of the system, and should only be
done by qualified service personnel.
Replacement parts for a double-insulated product must
be identical to the original parts.
A double-insulated product is marked with the words
“Double Insulation” or “Double Insulated”. Product
may also be marked with symbol shown here.
Before beginning assembly of product, make sure
all parts are present. Compare parts with package
contents list and hardware contents list. If any part is
missing or damaged, DO NOT attempt to assemble the
product.

OPERATING INSTRUCTIONS
You have now completed assembly and are ready to begin using your electric power washer. Read and observe all safety instructions.
• Turn on water supply at the faucet to completely
open.
• Make sure the “ON/OFF” switch is in the “OFF”
position. The power switch has international symbols for ‘on’ and ‘off’: On (|) Off (O).
• Unwind the power cord completely and plug the
GFCI into a grounded 120 volt outlet.
• Release safety push trigger lock up and back into
trigger. While pointing the spray gun in a safe direction, squeeze the trigger on the spray gun until there is a steady stream of water, letting the water and air out of the hose. Push trigger lock back down to lock back into place.
• Turn the power switch to the “ON” (|) position.
The unit will turn on for 1 - 2 seconds and shut
off. This is a normal function of the auto start
feature. Squeeze the spray gun trigger to begin
pressure washing.
• Begin power washing by squeezing the trigger on
the spray gun all the way into the handle.
• Release the spray gun trigger to stop the power
washer
• Allow the motor to come to a complete stop
before squeezing the trigger again.
• Squeezing rapidly will cause the auto start feature
to miss an on/off cycle that may prevent it from
turning on while squeezing trigger after rapid
squeezing. Use slow deliberate trigger pulls to
avoid such symptoms.

High Pressure Setting
Fan SprayPencil Stream
Using High/Low Nozzle
• High pressure spray is used for cleaning and low
pressure spray activates the detergent function.
• The adjustable spray nozzle had has two (2)
positions:
– IN position for high pressure spray. Twist the
nozzle counterclockwise until it stops and gap is
closed.
– OUT position for low pressure spray for detergent
function. Twist the nozzle clockwise until it stops
and gap is open.
• When using the high pressure setting, twist the
nozzle head clockwise or counterclockwise to
achieve the stream desired.
• When using the low pressure setting twist the nozzle
head clockwise to open the fan blades
all the way.
pressure spray, the variable spray head must be set for the “Pencil Stream”. This is when the metal blades in front of the nozzle are wide open so the detergent spray is not constricted.
• When using the detergent, fill it with a properly formulated detergent or cleaner with water ratio
• When removing the detergent tank remove lid and place finger in tank lifting up while pulling tank out.
according to instructions on the container.
• DO NOT use thick gel-like detergents, as they will clog the power washer and can cause damage.
• If you hear the motor run intermittently when the
trigger is not being squeezed, that is normal.
The pump is priming itself so it is ready to operate
when the trigger is squeezed. Turn off the power
washer if not being used after five minutes.
• The o-rings on the bayonet end of the nozzle lance
should be cleaned regularly and lubricated with nonwater soluble grease such as petroleum jelly.
• Keep the nozzle cleaning wire for use in unclogging
the nozzle. If you lose the cleaning wire, a straightened
paper clip also works.
How to Avoid Damaging Surfaces
• Damage to surfaces being cleaned occurs because
the impact force of the water pressure exceeds the
durability of the surface. Bare wood can be penetrated;
paint can be peeled off, etc. You can vary the force of
your power washer by controlling:
1. The angle of the surface being cleaned
2. The distance of the nozzle from the surface being
cleaned

• NEVER use a narrow high pressure stream of water on
soft surfaces susceptible to damage.
• Use the high/low nozzle lance when cleaning windows.
Be sure to adjust the nozzle to low spray and place
the nozzle approximately four to five feet away from
the window with the nozzle at forty five degree angle.
Squeeze the trigger and vary the spray pattern and
angle until optimum cleaning efficiency is achieved.
Using Power Cord
• Easily remove the power cord from side of unit by
swiveling the bottom blue cord hook to the right or
left until it faces up. The power cord then can be easily
slid off of the side of the power washer unit.
• Swivel blue, cord hook back down when ready to wrap
the cord back into place for storage.
• Use detergents designed for power washers. These
can be purchased online at our website www.
stanleyypressurewashers.com. Hardware stores or
home centers also have power washer detergents
for different cleaning projects. The cleaning solution
should be the consistency of water in order to
prevent clogging your detergent bottle and nozzle.
• This system applies detergent under low pressure.
The cleaning power of the detergents is enhanced
when applied with low pressure and enough
time is given to break down dirt and grime. The
combination of low pressure and chemical action is
very effective and can be better than scrubbing if
applied properly. ALWAYS spray detergent on a dry
surface. DO NOT pre-soak area. Wetting the surface
first dilutes
the detergent and reduces its cleaning ability. DO
NOT allow detergent to dry on surface. On vertical
surfaces being cleaned, apply detergent to lower
surfaces and work your way up to prevent detergent
from causing streaks in the dirt and grime. Rinse
detergent by pressure washing from bottom up for
same reason.
• If a stain is particularly tough, it may be necessary
to reapply the detergent and use a bristled brush to
scrub the stain. Subsequent power washing after
brushing should successfully complete your cleaning
job.
Cleaning Nozzles
• A clogged or partially clogged nozzle can cause
significant reduction of water pressure coming out
of the nozzle and/or cause the unit to pulsate while
spraying.
• Turn off the unit.
• Turn off the water supply to the unit.
• Relieve any pressure trapped in the hose by
squeezing the trigger 2-3 times, and then lock the
spray gun by pushing the lock button from left to
right.
• Remove the lance from the spray gun
• Using the nozzle tip cleaner provided (or an
unfolded paper clip), insert the wire into the
nozzle hole and move back and forth until debris is
dislodged.
• Tap quick connect end of lance on hard surface
several times
• Back flush water through the nozzles using garden
hose and highest pressure available (either standard
water nozzle or use your thumb over the nozzle to
create water pressure for back flush).
Cleaning Garden Hose Adapter
• The screens inside the clear garden hose adapter
should be cleaned periodically. Rinse it with clean
water, and then place it back in the adapter.
• When your pressure washing session has been
completed, turn off the power switch located on
the front of the power washer. Unplug the power
cord from the outlet. Turn off the water supply. Pull
the trigger on the spray gun 2-3 times to drain out
the excess water and to release any remaining water
pressure. Disconnect the garden hose adapter from
the water inlet. DO NOT allow the power washer to
run with no water flowing through it.
• Remove detergent bottle and clean completely.
Residual chemical will stick to the container and can
cause the detergent injector to clog and not function
properly.
• Remove high pressure hose from spray gun.
• Remove lance from the gun. Place the gun in the
holder on the side. Lances are placed into any of the
slots in the back of the unit. Make sure to discard any
remaining detergent from the bottle. Flush the bottle
and nozzle head with fresh water to prevent clogging.
• Hook the power cord around the L-shaped tabs on the
right side of the machine when facing it.
If you have any questions regarding the product, please call customer service at 1-866-508-1330.
PROBLEMCORRECTIVE ACTION
Unit will not turn on.1. The GFCI module on the end of the power cord must be plugged directly into an
outlet.
2. Do not use an extension cord.
3. With the GFCI Connected make sure the power switch is turned on.
Note: When power switch is turned on, the power washer will turn on by itself for 1-2
seconds and shut off. This is normal.
The high pressure
(HP) hose will
not connect/stay
connected to the
spray gun. Is this a
spray gun problem?
The unit is running
but there is no water
flow.
Why is water leaking
where the high
pressure hose connects
to the spray gun?
I can’t remove the
lance from the spray
gun. What should I
do?
1. In most cases, the spray gun is not the problem. The problem is the rubber sleeve
covering the fitting at the end of the high pressure hose. It has likely slipped up
toward the metal tip. To fix: wiggle, twist and/or pull the rubber sleeve down until the
entire tip is visible plus an 1/8 in. of the metal fitting below the tip. Now try to insert
the hose tip into the spray gun. It should “click” into place and will not come out until
the hose is released by pushing in the lever on the underside of the gun. You may cut
away the end of the sleeve with a sharp knife if unable to move the sleeve down. Be
careful not to cut or puncture the hose.
2. Do not push in the release button when connecting the high pressure hose.
1. Check the water source. Unclog the nozzle on the lance. (See nozzle cleaning
instructions under “Cleaning nozzles”.) Or take off the lance and just spray out of the
spray gun. This will indicate if the problem is with the lance.
1. Make sure there is an o-ring at the end of the metal tip of the high pressure hose.
If no o-ring is present, the connection between the hose and spray gun will leak.
O-Ring replacements are included in the package contents.
1. All lances and the detergent bottles are attached and removed from the extension
lance in the same manner. Insert the quick-release end of the lance/detergent bottle
into the extension lance. Press the extension lance and lance together (about a 1/8”)
and turn clockwise. The lance will lock in place. Remove the lance by reversing this
procedure. Press the extension lance and lance together and turn counter clockwise.
The lance will slide out.
2. Or, hold the extension lance and lance in an upright position with the nozzle end
on the floor. Push the whole assembly straight down to loosen the connection,
and then follow the removal process again. You may also spray soapy water or a
lubricant in the area where the lance connects to the extension lance.
The power washer
turns on for 2
seconds, shuts off,
and will not turn
back on. Do I have a
defective unit?
1. It sounds like your power washer is working just fine. When the water is connected,
the accessories are assembled properly, and the power switch is turned on, the power
washer may turn on for 1 - 2 seconds to prime the pump. It automatically shuts off
and waits for the spray gun trigger to be pressed. When the trigger is pressed, water
starts flowing through the pump. The water sensor in the pump “senses” the moving
water and automatically turns the power washer on.
2. Turn the power switch to off, hold in the trigger on the spray gun, so that you have a
steady stream of water. While you are holding the trigger open on the spray gun, at
the same time, turn the power switch on.
