IMPORTANT SAFETY INSTRUCTIONS
WARNING!
When using this product basic precautions should always be
followed, including the following:
Read all the instructions before us-
ing the product.
To reduce the risk of injury, close su-
pervision is necessary when a prod­uct is used near children.
Know how to stop the product and
bleed pressures quickly. Be thor­oughly familiar with the controls.
Stay alert – watch what you are do-
ing.
Do not operate the product when fa-
tigued or under the influence of alco­hol or drugs.
Keep operating area clear of all per-
sons.
Do not overreach or stand on unsta-
ble support. Keep good footing and balance at all times.
Follow the maintenance instructions
specified in the manual.
This Product Is Provided With A
Ground Fault Circuit Interrupter Built Into The Power Cord Plug. If Re­placement Of The Plug Or Cord Is Needed, Use Only Identical Re­placement Parts.
Risk of Injection or Injury – Do Not
Direct Discharge Stream At Per­sons.
High pressure jets can be dangerous
if misused. The jet must not be di­rected at persons, animals, electrical devices, or the machine itself.
Wear safety goggles.Do not use acids and solvents in this
product. These products can cause
physical injuries to the operator and irreversible damage to the machine.
To reduce the risk of electrocution,
keep all connections dry and off the ground. Do not touch plug with wet hands.
The Trigger Gun Safety Lock PRE-
VENTS the trigger from accidentally being engaged. This safety feature DOES NOT lock trigger in the ON position.
Do not use extension cord with this
unit.
WARNING
Do not spray electrical apparatus and wiring. Do not use with flammable liquids and toxic chemicals. Injection hazard: equipment can cause serious injury if the spray penetrates the skin. do not point the gun at anyone or any part of the body. In case of penetra­tion seek medical aid immediately. This system is capable of producing 12400 kPa /1800 PSI to avoid rupture and injury, do not operate this pump with components rated less than 12400 kPa /1800 PSI working pressure (including but not limited to spray guns, hose and hose connections). Before servicing, cleaning or removing any parts, shut off power and relieve pressure.
4 English
GROUNDING INSTRUCTIONS
This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resis­tance for electric current to reduce the risk of electric shock. This product is equipped with a cord having an equip­ment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in ac­cordance with all local codes and ordi­nances.
DANGER
Improper connection of the equipment­grounding conductor can result in a risk of electrocution. Check with a qualified electrician or service personnel if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the product - if it will not fit the outlet, have a proper outlet in­stalled by a qualified electrician. Do not use any type of adapter with this prod­uct.
GROUND FAULT CIRCUIT IN-
TERRUPTER PROTECTION
This product is supplied with a Ground Fault Circuit Interrupter (GFCI) built into the power cord plug. This device pro­vides additional protection from the risk of electric shock. If power is interrupted in the line, the GFCI will automatically re-close the circuit to the load after pow­er is restored. Depending on the GFCI model, it may be necessary to manually operate the reset button to restore pow­er to the GFCI load circuit. If replace­ment of the plug or cord is needed use identical replacement parts.
WATER SUPPLY
(Cold Water Only)
CAUTION
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. Direct connection via a receiver tank or backflow preventer, for example, is permitted. Dirt in the feed water will damage the unit. To avoid this risk, we recommend fitting a water filter.
Garden hose must be at least 1/2
inch or 5/8 inch in diameter.
Flow rate of water supply must not
fall below 2 GPM (gallons per minute).
Flow rate can be determined by run-
ning the water for one minute into an empty 5-gallon container.
The water supply temperature must
not exceed 104°F/40°C.
Never use the pressure washer to
draw in water contaminated with sol­vents, e.g. paint thinners, gasoline, oil, etc.
Always prevent debris from being
drawn into the unit by using a clean water source.

Deck Cleaning
(with or without detergent). Pre-rinse
deck and surrounding area with fresh water. If using detergent, apply to sur­face at low pressure. For best results, limit your work area to smaller sections of approximately 25 square feet. Allow detergent to remain on surface 1-3 min­utes. Do not allow detergent to dry on surface. Rinse at high pressure in a long sweeping motion keeping the spray nozzle approximately 3-6 inches from the cleaning surface. Always clean from top to bottom and from left to right. When moving on to a new section of the cleaning surface, be sure to overlap the previous section to eliminate stop marks and ensure a more even cleaning result.
House Siding

cleaning surface with fresh water. If us­ing detergent, apply to surface at low pressure (for best results, limit your work area to sections of approximately
6 feet and always apply detergent from bottom to top). Allow detergent to re­main on surface 1-3 minutes. Do not al­low detergent to dry on surface, if surface appears to be drying, simply wet down surface with fresh water. If needed, use special wash brush attach­ment (not included) to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 6 inches from the cleaning surface.
Cement Patios, Brick and Stone
(with or without detergent). Pre-rinse
