GENERAL SAFETY RULES
IMPORTANT SAFETY INSTRUCTIONS!
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
1. Keep your work area clean and well lit. Cluttered and dark work areas invite
accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence
of flammable liquids, gases, or dust. Power tools create sparks which may ignite
the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
SKU 47761 PAGE 3
For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual.
ELECTRICAL SAFETY
1. Grounded tools must be plugged into an outlet properly installed and grounded
in accordance with all codes and ordinances. Never remove the grounding
prong or modify the plug in any way. Do not use any adapter plugs. Check
with a qualified electrician if you are in doubt as to whether the outlet is properly
grounded. If the tools should electrically malfunction or break down, grounding
provides a low resistance path to carry electricity away from the user.
2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
3. Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
4. Do not abuse the Power Cord. Never use the Power Cord to carry the tools or
pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp
edges, or moving parts. Replace damaged Power Cords immediately. Damaged
Power Cords increase the risk of electric shock.
5. When operating a power tool outside, use an outdoor extension cord marked
“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the risk
of electric shock.
PERSONAL SAFETY
1. Stay alert. Watch what you are doing, and use common sense when operating
a power tool. Do not use a power tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry,
or long hair can be caught in moving parts.
3. Avoid accidental starting. Be sure the Power Switch is off before plugging in.
Carrying power tools with your finger on the Power Switch, or plugging in power
tools with the Power Switch on, invites accidents.
4. Remove adjusting keys or wrenches before turning the power tool on. A wrench
or a key that is left attached to a rotating part of the power tool may result in personal
injury.
5. Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
SKU 47761 PAGE 4
For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual.
6. Use safety equipment. Always wear eye protection. Nonskid safety shoes, hard
hat, or hearing protection must be used for appropriate conditions. Always wear
ANSI approved safety impact goggles and thick rubber boots during use and
maintenance.
TOOL USE AND CARE
1. Use clamps (not included) or other practical ways to secure and support a
smaller workpiece to a stable platform. Holding the work by hand or against your
body is unstable and may lead to loss of control.
2. Do not force the tool. Use the correct tool for your application. The correct tool
will do the job better and safer at the rate for which it is designed.
3. Do not use the power tool if the Power Switch does not turn it on or off. Any
tool that cannot be controlled with the Power Switch is dangerous and must be
replaced.
4. Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.
5. Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
6. Maintain tools with care. Keep tools clean. Properly maintained tools are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.
7. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have the
tool serviced before using. Many accidents are caused by poorly maintained
tools.
8. Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous when
used on another tool.
SERVICE
1. Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow instructions
in the
unauthorized parts or failure to follow maintenance instructions may create a risk of
electric shock or injury.

GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord plug provided with
the tool. Never remove the grounding prong from the plug. Do not use the
tool if the power cord or plug is damaged. If damaged, have it repaired by
a service facility before use. If the plug will not fit the outlet, have a proper
outlet installed by a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1. Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If the
tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of electric
shock. (See Figure A,
next page.)
2. The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the only
wire connected to the tool’s grounding system and must never be attached to an
electrically “live” terminal. (See Figure A.)
3. Your tool must be plugged into an appropriate outlet, properly installed and grounded
in accordance with all codes and ordinances. The plug and outlet should look like
that in the following illustration. (See Figure A.)
3-PRONG PLUG
ELECTRICAL OUTLET

SKU 47761 PAGE 8
For technical questions, please call 1-800-444-3353;
Troubleshooting section at end of manual.
EXTENSION CORDS
1.
Grounded
tools require a three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a serious
drop in voltage, resulting in loss of power and possible tool damage. (See Table A.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
WARNING! Do not use 16 or 18 AWG extension cords on this product.
4. When using more than one extension cord to make up the total length, make sure
each cord contains at least the minimum wire size required. (See Table A.)
5. If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Table A.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified
electrician before using it. Protect your extension cords from sharp objects, excessive
heat, and damp or wet areas.

CONTROLS AND SETUP
Note: Familiarize yourself with the location and function of all of the machine’s
controls before proceeding to setup of the machine.
CONTROLS AND FEATURES
1. The Pressure Washer features an automatic On/Off Micro Switch. The Motor (C)
of the Pressure Washer does not run continuously, but only when the Trigger (23A)
is squeezed. When spraying water through the unit stops, the Motor will automatically
shut off. However, the unit will build up heat while idle. If the unit is left to sit, then
the electrical circuit’s beaker will eventually trip. For this reason, if the unit is not to
be used for longer than 2 minutes, shut the Switch to “OFF”.
2. The Pressure Washer features a 3-Prong, Ground Fault Circuit Interrupter
(GFCI) Power Plug (95). The GFCI
Power Plug provides additional
protection from the risk of electrical
shock. Make sure that the Trigger (23A)
is released before plugging in. Plug the

SETUP
1. CHECK THE WATER SUPPLY. Prior to using the Pressure Washer for the first 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 (1.6 GPM).
This Pressure Washer will need about 3-4 GPM to operate correctly and efficiently.
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
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 nozzle.
Flow rate of the water supply must never be allowed to fall below 3 GPM.
To determine the water supply’s flow 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.
2. ARRANGE FOR A PROPER ELECTRICAL SUPPLY. This unit uses a large amount
of current, especially during start-up. 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 or lights that dim or
slow down while the washer is running. For best results, connect the plug to that
circuit’s outlet that is nearest to the circuit breaker panel.

3. MAKE SURE THE WASHER IS CLEAN AND READY FOR USE. Ensure the inlet
water strainer, nozzle, and the rest of the Washer are totally free of buildup or debris.
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 first, because the higher portions will typically
remain cleaner while the other areas are cleaned. Plan a safe direction for runoff to
flow while the job is being performed, and plan on working your way in that direction.
You will have a clearer idea of the time involved to clean the area after doing a test
run, as explained on page 15, #3.
5. PREPARE THE CLEANING AREA. Clear the cleaning area of all objects that are
not being cleaned. If any water prone or delicate items cannot be moved, protect or
move them. If detergent is to be used, cover or remove any plants or animals that
may be damaged by the chemicals in the cleaner.
6. PLACE THE PRESSURE WASHER IN AN APPROPRIATE LOCATION. The
location should be protected from any water from the cleaning area; if possible,
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 that can be reached with as short an extension cord as possible.

OPERATION
1. Make sure the Power Switch is in the “OFF” position. Attach the heavy duty
hose to the Pressure Washer, using the Heavy Duty Hose Adapter (G).
3. Attach the Spray Lance (K) or Detergent Bottle (H) into the Spray Wand Extension
(I), and press and twist the Wand into the Extension until the Wand locks in place.
(See Figure C, page 10.)
NOTE: The Pressure Washer will not pressurize if the Nozzle is not completely
assembled. It will not work properly with only part of the Wand installed.
4. Connect the High Pressure Hose (26A) to the Pressure Washer. (See Figure D.)
Make sure all connections are tight. Then, open the water supply valve fully. If
leaks occur, shut off water and retighten connections.
5. IMPORTANT! Prior to turning on the Pressure Washer, connect the unit to the
water supply. Turn on the water, disengage the safety, and squeeze the Trigger
(23A) until water flows out of the Gun Assembly (E) without sputtering. This
removes air from the system and allows the unit to properly perform.
follow this step can damage the Pump.
6. Test the cleaning capabilities and the run before starting your cleaning project, as
explained on page 16, #1. Turn the Power Switch to the “ON” position. The motor
will briefly run when the switch is first turned on to build up pressure and then
go to standby until the trigger is squeezed. DO NOT ALLOW THE UNIT TO REMAIN
IDLE FOR MORE THAN A MINUTE OR TWO; the unit will build up heat when it
is on standby mode.

OPERATING TIPS
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 Operating Controls
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 on the next page. Use this area to approximate the
amount of time required for the project. Be certain to factor in time for touch-ups and
cleanup after the general cleaning is finished.
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.
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
However, certain use techniques may help reduce or even prevent the need for such rest
periods, increasing efficiency:
a. SHUT OFF THE MACHINE IF THE UNIT IS TO SIT IDLE FOR MORE THAN 2
MINUTES. Heat will build up within the unit as it draws current while
recirculating the water. If left for long enough, it will overload the circuit it is
powered by and trip the circuit breaker.
b. 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.
c. Make sure that all obstacles have been moved and the entire area is ready before
starting.
d. For small jobs, try to finish an entire portion of the job before taking a break.
(see Troubleshooting, page 22).

CLEANING RECOMMENDATIONS
1. Clean an inconspicuous test area to help avoid damaging the surface: Always
begin with the fan spray at a distance of about 3-5 feet from the surface being cleaned
to avoid damaging the surface of the object. Make sure that the test area is clear of
people and water prone/delicate 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.

4. If detergent is to be applied: Only use pressure washing detergent; other detergents
might clog or damage the pressure washer. Apply the detergent at low pressure by
using the Detergent Bottle (H). Allow the detergent several minutes to sit and soak
into the work surface; this will improve cleaning efficiency. Make certain to rinse off
all detergent completely.
5. Hold the Gun Assembly 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

6. 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.
7. If wood is being cleaned, be careful not to damage it. Wood will usually require
resurfacing (sanding) and re-coat with a surface protectant (wood, stain, varnish)
after it has dried again. Try to avoid leaving water on a wooden surface; doing so
can harm the surface.

INSPECTION, MAINTENANCE, AND CLEANING
1. WARNING! Make sure that 1) the Trigger is locked in its off position, 2) the
Power Switch of the Pressure Washer is in its “OFF” position, 3) the plug is unplugged
from its electrical outlet, 4) that the water supply is shut off, and 5) all residual water
pressure is safely expelled before performing any inspection, maintenance, or
cleaning procedures. Point the Gun Assembly (E) in a safe direction and discharge
all remaining pressure. Then, disconnect the Heavy Duty hose from the unit.
2. Before each use, inspect the general condition of the Pressure Washer. Check for
loose screws, misalignment or binding of moving parts, damaged electrical wiring,
damaged High Pressure Hose, damaged accessories, and any other condition that
may affect its safe operation. If abnormal noise or vibration occurs, have the problem
corrected before further use.
Do not use damaged equipment.
3. To clean, remove excess water from the Pump by tipping the unit on both sides to
drain any remaining water from the inlet and outlet fittings. Drain the Detergent
Dispenser and flush with running water. Use only a clean cloth and mild detergent
to clean the body of the Pressure Washer. Do not use solvents. Remove the Inlet
Filter and run water through it backwards to remove any debris.
Do not immerse any part of the tool in liquid. Dry off any remaining water on all
parts and fittings. Then engage the Trigger Safety Lock.
Use the included Wire Tip Cleaner (I) to help remove mineral deposits from the
nozzle. 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 the
nozzle.

4. STORAGE: When storing, always completely empty the Pressure Washer of water.
Frost will damage the Pressure Washer if the unit contains water. Store the Pressure
Washer indoors in a dry, frost-free room. Minerals in the water can harden inside the
workings. Flush the unit with automotive antifreeze prior to long-term storage. Always
dispose of antifreeze in accord with local ordinances.
