PRESSURE WASHER SAFETY RULES
WARNING: To avoid mistakes and serious injury, do not plug in your tool until you have read and
understood the following safety rules. Learn the tool’s applications, limitations, and possible hazards to
maximize your safety and the lifetime of the tool.
BEFORE OPERATION
1. KNOW YOUR TOOL. Be thoroughly familiar with the controls of your pressure washer. Know how to stop
the water 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 components 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 injury, wear safety goggles and ear protection. Wear
rubber-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
broken 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 ensure 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 ap-
pliance 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 associated 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 exceed 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 areas the unit MUST NOT be connected directly
to the public drinking water supply. This is to ensure that there is no feedback of chemicals into the water supply.
If connection is made to a potable water system, the system MUST be protected against backflow. Direct connec-
tion 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).

PRESSURE WASHER SAFETY RULES
Safety is a combination of common sense, staying alert and knowing how your tool works.
SAVE THESE SAFETY INSTRUCTIONS.
OPERATING THE PRESSURE WASHER
1. STAY ALERT. Watch what you are doing and use common sense when operating your tool. Do not use the
tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention during
operation may result in serious bodily injury.
2. INJECTION HAZARD. The high pressure stream of water can cut through skin and cause serious injury. Keep
clear of the nozzle. Never direct the discharge stream at any bystanders, animals or your foot.
3. RISK OF EXPLOSION. Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Do not spray flammable liquids.
4. RISK OF ELECTRIC SHOCK. Do not spray electrical apparatus and wiring. Do not spray the power source or
the outlet. Don’t pressure wash the pressure washer.
5. TOOL PURPOSE. Learn your tool’s applications and limitations as well as the specific potential hazards related
to this machine. Only use the pressure washer for its intended purposes. Otherwise, you may cause mechanical
defects, serious damage or personal injury.
6. DO NOT OVERREACH. Keep proper footing and balance at all times. This enables better control of the unit
in unexpected situations and will also prevent you from falling down and embarrassing yourself in front of your
cool neighbor Greg. When stepping backwards, be cautious about any obstacles beneath your feet or behind you
in order to avoid falling.
7. AVOID ACCIDENTAL START-UPS. Make sure the power switch is in the OFF position before connecting
the plug to a power source or carrying the tool. Engage the gun safety lock whenever the machine is not in use.
8. GUN KICKS BACK. Hold the gun firmly with both hands. Kickback from operation can cause the user to fall
down. Always operate the pressure washer on a level and non-elevated surface to prevent the risk of falling.
9. SHUT DOWN THE UNIT. Never leave your unit running while unattended. Unplug the unit before leaving
for extended periods of time.
10. MAINTENANCE. Before cleaning, changing accessories, or performing any maintenance, shut off and
disconnect the unit from the electrical supply, then relieve pressure in the washer by squeezing the trigger to
empty the washer of any residual water.
11. STORAGE. Store your machine and accessories indoors. Never store the pressure washer outdoors. If the
pump freezes, permanent damage may result. Always keep tools clean and in good working order.
12. REPLACEMENT PARTS. Use only identical replacement parts. Use of any other part can cause personal
injury and damage to the tool. Only have your power tool serviced by a qualified repair person.
5

IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and
should be done only by a 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
extension cord, reverse the plug. If it still does not fit, use a correct polarized extension cord or contact a qualified
electrician to install the proper outlet. DO NOT modify the machine plug or the extension cord in any way.
2. 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.
3. SERVICE AND REPAIR. To avoid danger, electrical appliances must only be repaired by qualified service
technician using original replacement parts; otherwise this may result in considerable damage to the user.
GUIDELINES 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. Run-
ning at a lower voltage will damage the motor.
DOUBLE-INSULATED TOOLS
Your pressure washer electrical system is double insulated, where two systems of insulation are pro-
vided instead of grounding. Double insulated tools do not need to be grounded, nor should a means
for grounding be added to the product.

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 8.
• 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.
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.
WARNING: To prevent serious injury, make sure all the warnings and instructions have been read and
understood before operating this tool.
