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 flammables.
1. Keep your work area clean and well lit. Cluttered benches and dark areas
invite accidents.
WORK AREA
ELECTRICAL SAFETY
3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
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
fromthe 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 immedi-
ately. 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 oper-
ating a power tool. Do not use a power tool while tired or under the influ-
ence of drugs, alcohol, or medication. A moment of inattention while operat-
ing 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/Trigger, 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.
6. Use safety equipment. Always wear eye protection. Non-skid 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 or other practical ways to secure and support the workpiece to
a stable platform. Holding the work by hand is unstable and may lead to loss of
control. Only work on a workpiece that is properly secured. Holding any object
while it is pressure washed can cause serious personal injury by the high pres-
surestream.
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. Do not use
small equipment, tools, or attachments to do the work of larger industrial equip-
ment, tools, or attachments. Do not use this product for a purpose for which it was
not intended.
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.

SKU 92146 For technical questions, please call 1-800-444-3353. PAGE 5
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. 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 main-
tained 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 “Inspection,Maintenance, And Cleaning” section of this

3-PRONGPLUG
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
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 Figure B, next page.)
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.
(See Figure B.)
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 Figure B.)
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 Figure B.)
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.)
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.)

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.
8. Protect your extension cords from sharp objects, excessive heat, and damp or wet
areas.
9. If an extension cord is needed, only use a cord with the proper gauge wire.
(See Figure B.)

PRODUCT FEATURES AND PRECAUTIONS
NOTICE: Prior to using the pressure washer for the first time, it is IMPORTANT
that it has been determined that there is an adequate water supply.
The Pressure Washer needs TWICE the volume of the stated water
output (1.7 GPM). This Pressure Washer will need 3.4 GPM to oper-
ate correctly and efficiently. If the water is supplied by a well, make
certain that the well produces enough water to keep up with the Pres-
sure Washer’s water demand. FLOW RATE OF THE
WATER SUPPLY MUST NEVER FALL BELOW 3 GPM. Flow rate
can be determined by running the water at full pressure (valve com-
pletely open) for one minute into an empty 5 gallon container, then
measuring the amount of water in the container.
CAUTION! If the pump is run without an adequate water supply, the Pres-
sureWasherwillcavitate. Cavitationcausesthepumptovibrate
and operate loudly, and will damage the pump.
1. IMPORTANT! Prior to turning on the PressureWasher connect the unit to the
water supply. Turn on the water and squeeze theTrigger (23A) until water flows
out of the Wash Gun. This removes air from the system and allows the unit to
properly perform. Failure to follow this Step will damage the Pump.
2. The Pressure Washer features an automatic ON/OFF Micro Switch (27). The
Motor (33) 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.
3. The Pressure Washer features a 3-Prong,
Ground Fault Circuit Interrupter (GFCI)
Power Plug (59). The GFCI Power Plug pro-
vides additional protection from the risk of
electricalshock. Makesure theTrigger(23A) is
released before plugging in. Plug the GFCI
Power Plug into a grounded, 120 volt, electri-
cal outlet. Press theTEST button and then the
RESETbutton. Theindicator onthePowerPlug
should appear red. If the indicator is not red
after several tries, have both the Power Plug
and receptacle inspected by a qualified electri-
cian. Should replacement of the GFCI Power
Plug become necessary, only a qualified tech-
nician should perform the service. Never
attempttoalter or disablethe GFCI PowerPlug.
