Operating Instructions
Read the ENTIRE IMPORTANT
SAFETY INFORMATION section at the
beginning of this manual including
all text under subheadings therein
before set up or use of this product.
Work Piece and Work
Area Set Up
1. Designate a work area that is clean and welllit. The work area must not allow access by
children or pets to prevent distraction and injury.
2. CHECK THE WATER SUPPLY. Prior to using the
Pressure Washer for the rst time, it is ESSENTIAL
to verify that the water supply is adequate. The
Pressure Washer needs TWICE the water supply
(or volume) than the stated water output (1.3 GPM).
This Pressure Washer will need about 2.6-3 GPM to
operate correctly and efciently. If the water is being
supplied by a well/pump, make certain that the well/
pump produces enough water to keep up with the
Pressure Washer’s water demands. Water supply
hoses should be heavy duty to withstand the forces
involved. Water hoses up to 25' long must be 5/8" ID.
Water hoses up to 50' long must be 3/4" ID. Do not
use hoses longer than 50'. The more minerals in the
water (the harder the water) you use, the more often
mineral buildup will need to be cleaned out from the
nozzles. The ow rate of the water supply must never
be allowed to fall below 2.6 GPM.
To determine the water supply’s ow rate: Run the
water at full for one minute into a 5 gallon container,
and measure the amount of water in the container.
CAUTION! If the Pressure Washer is run
with an inadequate water supply, the pump
will cavitate. Cavitation causes the pump
to operate loudly and will damage it.
3. ARRANGE FOR A PROPER ELECTRICAL SUPPLY.
This unit uses a large amount of current, especially
during start-up. Turn off power switch, then connect
this unit only to a dedicated household circuit
capable of providing ample current to it. A dedicated
circuit has no additional loads (running devices)
connected to it; shut off any appliances that slow
down or lights that dim while the washer is running.
For best results, connect the plug to that circuit’s
outlet that is nearest to the circuit breaker panel.
4. PLAN OUT THE JOB: Plan out what areas will be
cleaned, how many sessions will be necessary,
and how long the individual sessions of work will
need to be. Plan to clean the higher portions rst,
because the higher portions will typically remain
cleaner while the other areas are cleaned. Plan a
safe direction for runoff to ow while the job is being
performed, and plan on working your way in that
Page 8 For technical questions, please call 1-800-444-3353. SKU 68333
direction. You will have a clearer idea of the time
involved to clean the area after doing a test run.
5. Clear the cleaning area of all objects that
are not being cleaned. If any water prone or
delicate items cannot be moved, protect them. If
detergent is to be used, cover or remove any
plants or animals that may be damaged by the
detergent. Disconnect power to and protect any
nearby electrical wiring from water and spray.
6. Place the Pressure Washer in a location which is
protected from any water from the cleaning area.
Select a location higher than the cleaning area. The
pressure washer’s location should be close enough
so that the hose will reach every portion of the job to
be done with some slack for movement. Also, select
an area with proper access to a dedicated circuit.
7. Route the power cord along a safe route to reach
the work area without creating a tripping hazard or
exposing the power cord to possible damage. The
power cord must reach the work area with enough
extra length to allow free movement while working.
c.
Insert the Extension Nozzle into the large end
of the Dispenser cap, pressing until it clicks into
place.

General Operating Instructions
1. Point the Nozzle in a safe direction and
squeeze the trigger to check that all pressure is
released from the unit. Release the Trigger.
2. Turn on the water supply, then
turn on the Power Switch.
Note: If the unit does not turn on or turns off
suddenly, check and reset the GFCI.
3. Unlock and squeeze the Trigger to start
the stream. Be aware that when it is rst
started, the gun will kick back.
4. Test spray the edge of the surface to be cleaned
to make sure that the stream is not too strong for
the surface. Adjust the pressure by squeezing
the Trigger more or less, and by changing your
distance from the surface. Adjust the stream from
a fan to a direct stream by turning the nozzle.
5. When nished using the Pressure Washer,
release the Trigger, turn the Power Switch off,
unplug the unit, and turn off the water supply.
6. Point the Nozzle in a safe direction and squeeze
the trigger to check that all pressure is released
from the unit. Release and lock the Trigger.
7. Clean, then store indoors, out of children’s reach.
Operating Tips
Use Proper Pressure Washer Operation Techniques:
The machine may suddenly stop and require a rest
period from time to time; this is normal and does
not indicate a problem (See Troubleshooting
Section). However, certain operating techniques
may help reduce or even prevent the need for
such rest periods, increasing efciency:
a. Do not release the trigger between sweeps.
Release the trigger as few times as possible
during use. Interrupted or sporadic spraying
will cause the unit to heat up quickly and
will increase the need for rest periods.
b. Make sure that all obstacles have been moved
and the entire area is ready before starting.
c. For small jobs, try to nish an entire portion
of the job before taking a break.
Cleaning Recommendations
5. Clean an inconspicuous test area rst. Always begin
with the fan spray at a distance of about 3-5 feet from
the surface being cleaned to avoid damaging it. Clear
the test area of people and water-sensitive objects.
If a pressure washing detergent is to be used, apply
the detergent to this area as well. After cleaning this
area, switch off the pressure washer and inspect
the area carefully for any damage or discoloration.
If any damage is noted from the pressure setting,
use a lighter setting when cleaning the rest of the
area. If damage or discoloration is noted from
the detergent, do not use it when cleaning.
Become Familiar With your Machine:
1. Before beginning work, set aside enough
time to familiarize yourself with this machine’s
cleaning rate and capacity along with all
instructions and precautions contained in this
section, along with the Operating Instruction
and Controls and Features sections.
2. This unit is intended for various light to moderate
cleaning applications. If deeper cleaning is desired, it
can be attained at times, however this is done at the
expense of speed. This unit is not intended for paint
stripping or deep concrete cleaning applications.
3. Clean a test area to satisfaction before
proceeding with the entire area, as stated
in Cleaning Recommendations.
4. This unit has several settings and adjustments
that effect the speed of cleaning and the
water force applied to cleaning. Good
guidelines to keep in mind are:
WIDE STREAM =
QUICKER COVERAGE BUT
LIGHTER CLEANING.
NARROW STREAM =
DEEPER CLEANING BUT
SLOWER COVERAGE.
6. First, pass over the area with a light cleaning,
and then more thoroughly clean it.
For a vertical or sloped surface:
a. Wash from the top down.
b. If possible, direct the stream in the same
direction as the slope towards a draining
area. This will enable better drainage
and therefore better cleaning.
For a at surface:
a. If a thin layer of water accumulates on
the surface, periodically use the stream to
direct this water towards the drainage.
b. After the major cleaning is done, sweep
the surface with the stream to help direct
loose debris toward the drainage.
7. If detergent is to be applied: Only use pressure
washing detergent in the soap dispenser; other
detergents will clog the dispenser. Do not add
detergent to the body of the pressure washer.
Spray the surface with detergent until evenly
covered, then turn off the machine and water
source, release pressure, and remove the soap
dispenser. Allow the detergent several minutes to
sit and soak into the work surface; this will improve
Page 10 For technical questions, please call 1-800-444-3353. SKU 68333
cleaning efciency. Turn on the water source and
power, and rinse off all detergent completely.
8. Hold the Water Gun at about a 45° angle and
steadily sweep the stream back and forth; if a
severe, head-on angle is used, dirt may imbed
in the surface being cleaned. Follow a steady,
consistent pace during cleaning; this will help prevent
stripes or discoloration afterwards. If streaking or
uneven cleaning is noted at the end of a project,
go over the edges of the streaks with a wide fan
pattern to help blend these lighter areas in.
9. If several different surfaces are to be cleaned,
be careful not to damage any of the less solid
surfaces while trying to clean the harder ones.
This is especially a concern when cleaning tile and
grout, bricks and mortar, or stones and mortar.
10. If wood is being cleaned, be careful to avoid damage.
Wood will usually require resurfacing (Sanding)
and re-coat with a surface protectant (wood, stain,
varnish) after it has dried. Try to avoid leaving water
on a wooden surface; doing so can harm the surface.

may affect its safe operation. If abnormal noise or
vibration occurs, have the problem corrected before
further use. Do not use damaged equipment.
any remaining water on all parts and ttings.
Remove mineral deposits from the nozzle using
a thin, stiff wire. The more minerals that are
dissolved in the water (the harder the water)
you use, the more often mineral buildup will
need to be cleaned out from inside nozzle.
3. In areas that have hard water (water rich in minerals
such as calcium) the unit will need to be cleaned
periodically to remove calcium buildup which can clog
the system. To clean off calcium buildup: Unplug the
unit and lay it face down. Fill the body at the water
inlet tting with calcium remover and allow at least 5
hrs for calcium deposit to break down. Rinse and dry.
4. STORAGE: When storing, empty the Pressure
Washer of water. Frost will damage the Pressure
Washer if the unit contains water. Store the Pressure
Washer in a dry, frost-free room. Flush the unit with
automotive antifreeze prior to long-term storage.
