GENERAL SAFETY RULES
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liquids,
gases or dust. Power tools create sparks which may ig-
nite the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never mod-
ify the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
4. Do not abuse the cord. Never use the cord for car-
rying, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of elec-
tric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respira-
tory mask, non-skid safety shoes and hearing protection
used for appropriate conditions will reduce the risk of
personal injury.
3. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites
accidents.
4. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key 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. This enables better control of the power
tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-
elry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

GENERAL SAFETY RULES
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
2. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained us-
ers.
5. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s opera-
tion. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situa-
tion.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.
SERVICE
1. Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is main-
tained.

1. Know Your Tool. Be thoroughly familiar with the con-
trols of your pressure washer. Know how to stop the wa-
ter pressure quickly by releasing the trigger, shutting off
the unit and turning off the water supply.
2. Use Suitable Components. This system is capable of
producing pressure up to 2000 PSI/13,800 kPa. To avoid
rupture and injury, do not operate this pump with com-
ponents rated less than 2000 PSI/13,800 kPa working
pressure (including but not limited to spray guns, hoses
and hose connections).
3. Operating Environment. Keep bystanders, children
and animals at a safe distance away from the work area.
Do not operate near flammable materials or explosive
vapors.
4. Wear Safety Equipment. For protection against in-
jury, wear safety goggles and ear protection. Wear rub-
ber-soled shoes during operation to reduce the risk of
electric shock.
5. Preliminary Unit Inspection. Thoroughly inspect the
unit and accessories prior to operation. Make sure all
the parts are secured and installed correctly. Do not use
plugs or cords that show signs of damage such as bro-
ken or cracked insulation. Have damaged items repaired
or replaced as necessary. Always perform a test run the
first time you use the tool or after replacing parts to en-
sure that the unit is functioning properly.
6. Malfunctioning Switch. Do not use the tool if the
switch does not turn on and off. Any electrical appliance
that cannot be controlled by the switch is not safe to use
and must be repaired.
7. Detergent Safety. Always be aware of the dangers as-
sociated with the detergents and chemicals that you are
working with. Follow the warnings and instructions that
come with your detergent for proper use.
WATER SUPPLY REQUIREMENTS
1. Cold water ONLY. Use the pressure washer with cold
water only. The water supply temperature must not ex-
ceed 104°F/40°C.
2. Potable Water Restrictions. When connecting the
water inlet to the water supply mains, local regulations
of your water company must be observed. In some ar-
eas the unit must not be connected directly to the pub-
lic drinking water supply. This is to ensure that there is
no feedback of chemicals into the water supply. If con-
nection is made to a potable water system, the system
MUST be protected against backflow. Direct connection
via a receiver tank or backflow preventer, for example, is
permitted.
3. Avoiding Dirt. Always prevent debris from being
drawn into the unit by using a clean water source. Dirt in
the feed water will damage the unit. Your washer is pre-
installed with a water filter inside the water inlet. Inspect
and clean the filter regularly. Never use the pressure
washer to draw in water contaminated with solvents,
e.g. paint thinners, gasoline, oil, etc.
4. Water Flow. The garden hose must be at least 5/8
inch in diameter. Flow rate of water supply must not fall
below 2 GPM (gallons per minute).
7

PRESSURE WASHER SAFETY WARNINGS
WARNING! Do not operate the power station until you have read and understood the following instructions
and the warning labels.
ELECTRICAL INFORMATION
IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and
should be done only by qualified service personnel using identical replacement parts. Always use original factory
replacement parts when servicing.
1. Polarized Plugs. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified electrician to install a proper outlet. Do not modify the machine
plug or the extension cord in any way.
1. Ground fault circuit interrupter Protection (GFCI). This pressure washer is provided with a ground-fault circuit-
interrupter (GFCI) built into the plug 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.
2. Service and repair. To avoid danger, electrical appliances must only be repaired by a qualified service technician
using original replacement parts.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
Use of an extension cord with this product is NOT recommended. If an extension cord must be used, use only a
UL-, CSA- or ETL-rated extension cord that are intended for outdoor use to prevent electric shock. These cords are
identified by a marking, “Acceptable for use with outdoor appliances, store indoors while not in use.”
1. Only use extension cords that can handle the voltage and amperage rating of this product. The extension cord
must be 14 gauge or heavier, and the length must not exceed 25 feet.
2. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition.
Always replace a damaged extension cord or have it repaired by a qualified person before using it.
3. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on
plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
4. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be
protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in
the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running
at a lower voltage will damage the motor.
DOUBLE-INSULATED TOOL
The tool’s electrical system is double-insulated where two systems of insulation are provided. This
eliminates the need for the usual three-wire grounded power cord. Double-insulated tools do not need
to be grounded, nor should a means for grounding be added to the product. All exposed metal parts are
isolated from the internal metal components with protecting insulation.

OPERATION
WARNING! To prevent serious injury, make sure all the warnings and instructions have been read and
understood before operating this tool.
PREPARING THE PRESSURE WASHER
1. Place the pressure washer on a secure, stable surface to prevent it from tipping during operation.
2. Check that all connections have been properly installed and secured according to the instructions on page 10.
• The high pressure hose is properly fastened to the machine water outlet and the gun hose connector.
• The spray lance is properly attached to the trigger gun.
• The garden hose is properly fastened to the pressure washer’s water inlet adapter.
CAUTION: This unit is intended to be used with cold water only. Do not use hot water in this pressure washer.
3. Turn on the water supply to its maximum flow.
4. It is very important to bleed all the air out of the pressure washer before using it. Release the safety lock and
pull the trigger for a few seconds until the water flow is steady. This will allow air to escape and discharge any pre-
existing pressure from the gun and the hose. Then turn off the water.
OPERATING THE PRESSURE WASHER
1. Make sure the on/off switch is in the off position. Plug the Ground Fault Circuit
Interrupter (GFCI) into a matching receptacle (see page 10 for important electrical
information). We recommend that you test the GFCI as part of your startup procedure
each time you use your pressure washer as instructed below.
Press the RESET button (top), and the power indication light should turn on. Press
the TEST button (bottom), and the power indication light should turn off. Do not use
if test fails. Press RESET button again after completing the test to enable operation
(Fig. 8).
2. Point the gun at a safe direction, aimed away from any bystanders or animals. Set
the ON/OFF switch to ON (Fig. 9).
3. Hold the gun firmly and pull the trigger to begin pressure washing. Beware of kick-
back when pressing the trigger.
WARNING! Never direct the water steam at people, animals or electrical
devices. The high-pressure spray can cause severe injury.
AUTOMATIC PUMP SHUTOFF/ TTS (TOTAL STOP SYSTEM)
The pressure washer is equipped with an automatic pump shutoff function that senses the water flow in the pump.
The pump will only run when the power switch is in the ON position and the trigger pulled. When the trigger is
released and no water is flowing through the pump, the motor will automatically shut off to protect the pump from
overheating, thus saving energy and prolonging pump life.
So don’t worry if the pump shuts off when the trigger is released. Your pressure washer is still okay. Simply squeeze
the trigger again to resume pressure washing.

OPERATION
THERMAL PROTECTOR
Your pressure washer is also equipped with a motor thermal protector. When the motor is experiencing overload
and over heats, the thermal protector will trip to shut down and protect the motor. Wait a few minutes for the motor
to cool down and the thermal protector will reset automatically.
PRESSURE WASHING TIPS
1. Before pressure washing any surface, test spray an inconspicuous area. Adjust the spray pattern and spraying
distance to achieve the optimal cleaning result and prevent damaging the surface.
2. Use caution when spraying clipped or peeling paint, as the high pressure may remove the loose paint from the
surface.
3. Pre-rinse the surface with fresh water before applying detergent.
4. When using detergent, follow the instructions that come with your detergent. In general, allow the detergent to
remain on the surface about 1-3 minutes. Do not allow detergent to dry on the surface.
5. Keep the spray nozzle approximately 6 inches from the cleaning surface. The spraying distance may vary accord-
ing to the treated surface (be sure to increase the distance when rinsing sensitive or fragile surfaces). Rinse the
surface in a long sweeping motion.
6. Clean from top to bottom. When moving on to a new section of the cleaning surface, overlap the previous section
to eliminate stop marks and ensure a more even cleaning result.
7. When pressure washing surfaces that may come in contact with food, flush surfaces with plenty of drinking water
after pressure washing. However, WEN does not recommend eating off of your driveway.
SHUTTING DOWN THE UNIT
When the pressure washing task has been completed, follow the steps below to shut down the unit.
1. Turn off the ON/OFF switch and unplug the power plug from the outlet.
2. Turn off the water supply.
3. Pull the high pressure gun trigger to relieve all the built-up pressure in the machine.
4. Release the trigger and engage the gun safety lock.
NOTE: To maximize safety, always engage the safety lock when the gun is not in use.
5. Disconnect the garden hose from the water inlet on the back of the unit.
6. Disconnect the high pressure hose from the pressure washer outlet.
7. Follow the instructions on the next page for properly maintaining and storing your pressure washer.

MAINTENANCE & STORAGE
NOTE: Replacement parts can be ordered from wenproducts.com by searching the part number (refer to the ex-
ploded view and parts list on pages 16 & 17). Use only identical replacement parts designated from your pressure
washer. Parts that wear down over the course of normal use (such as hoses, filters, nozzles, etc.) are not covered
by the two-year warranty.
HIGH PRESSURE HOSE
The high pressure hose (PW19-016) can be damaged easily and should be carefully stored. Do not kink the hose.
Do not drive vehicles or place heavy objects over the hose. Do not expose the hose to sharp objects. Don’t chew on
it either. Regularly inspect the hose for cuts, bulges, or leaks which can develop from kinking or wear. If damage is
found, replace the hose immediately to prevent serious injuries.
WARNING! Risk of electric shock - Always switch off the pressure washer, disconnect the power plug and
turn off the water before performing any adjustments or maintenance.
WATER INLET FILTER
Check the water inlet filter (PW19-025) periodically for deposits. Clean this
filter regularly for maximum performance. Remove the water inlet filter
(Fig. 10) and rinse it with warm water to clean out debris and buildup before
operating the pressure washer.
SPRAY NOZZLE
Regularly clean the spray tip on the spray lance and detergent bottle to pre-
vent the nozzle from clogging.
Make sure the power plug is disconnected, the water is turned off and all
pressure is relieved from the unit. Turn the adjustable nozzle counterclock-
wise to move the metal plates apart. Use a nozzle cleaner (Fig. 11) or a
needle to dislodge any foreign materials that are clogging or restricting the
spray tip.
STORING THE PRESSURE WASHER FOR EXTENDED PERIODS
1. Clean the spray nozzle and water inlet filter before storing the unit.
2. To protect and extend the life of your pressure washer, we recommended running the unit with a pump antifreeze
or pump protector or a pump conditioner before storing the unit for long periods of time. Follow the directions on
your preferred pump protector for proper use.
3. Store your pressure washer and accessories indoors where the temperature will stay above freezing (32°F/0°C).
Do not store it near the furnace or other sources of heat as it may dry out the pump’s seals.
4. Keep the pressure washer upright on a level surface. Cover the machine to protect it from dust. Do not allow high
pressure hose to become kinked during storage.
