ELECTRICAL

ELECTRICAL CONNECTION

This product has a precision-built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC only (normal household current). Do not operate this product on direct current (DC). A substantial voltage drop will cause a loss of power, and the motor will overheat.

DRIP LOOP

To prevent water from flowing along the power cable and possibly reaching the electrical outlet and plug, we recommend using a simple drip loop.

CONNECTING THE GARDEN HOSE

CAUTION

Always observe all local regulations when connecting hoses to the water main. Some areas have restrictions against connecting directly to the public drinking water supply to prevent the feedback of chemicals into the drinking water supply. Direct connection through a receiver tank or backflow preventer is usually permitted.

• Uncoil the garden hose.

NOTE: There must be a minimum of 10 feet of unrestricted garden hose between the water inlet and the garden hose faucet or shut-off valve (such as a “Y” shut-off connector).

• Run water through the garden hose for 30 seconds to clean any debris from the garden hose.
• Inspect the screen in the water inlet (10).
• If the screen is damaged, do not use the machine until the screen has been replaced.
• If the screen is dirty, clean it before connecting the garden hose to the machine.

APPLICATIONS

You may use this product for the purposes listed below:

Cleaning boats, cars, trucks, motorcycles, outdoor furniture, grills, house siding, driveways, patios, and decks.

DETERGENT ADDING AND USE

Use only detergents designed for pressure washers; household detergents, acids, alkalines, bleaches, solvents, flammable material, or industrial-grade solutions can damage the pump. Many detergents may require mixing prior to use. Prepare cleaning solution as instructed on the solution bottle.

SOAP APPLICATION

Soap is applied under low-pressure, high-volume conditions for optimum performance.

Soap can not be applied under high pressure with this machine.

Soap/detergent can only be applied with this machine when the black (75-degree) soap tip is installed.

To add detergent:

• Place the pressure washer upright on a flat surface.
• Remove the cap from the detergent tank.
• Pour detergent into the tank.
• Reinstall the cap.

CAUTION

Use only approved pressure washer cleaners. Do not use bleach, chlorine, or any cleaners containing acids.

To use:

• Connect the low-pressure black soap spray tip to the wand connector.
• Squeeze the trigger, and the detergent will automatically be mixed with the water and dispensed from the spray tip.

NOTE: Use a funnel, if needed, to prevent accidental spilling of the detergent outside the tank. If any detergent is spilled during the filling process, make sure the unit is cleaned and dried before proceeding.

STARTING AND STOPPING THE PRESSURE WASHER

CAUTION

Do not run the pump without the water supply connected and turned on.

• Connect the garden hose.
• Turn the water supply on, then squeeze the trigger and run the water hose with the motor in the OFF position until a steady stream of water appears. This helps drain air from the tank and lines.

NOTE: If the pressure washer pulsates and the water stream is intermittent, turn the pressure washer off and continue to bleed air out of the system. Ensure to check that the garden hose is fully turned on and not kinked.

• After ensuring the On/Off switch is in the OFF ( O ) position, connect the pressure washer to the power supply.
• Press the switch to the ON ( I ) position to start the motor.
• To stop the motor, release the trigger and press the switch to the OFF ( O ) position.

NOTE: The pressure washer may be on and the system may have pressure even when the pump and/or motor cannot be heard running. Always use caution around the pressure washer.

CAUTION

Hold the trigger handle securely with both hands. Expect the trigger handle to move when the trigger is pulled due to reaction forces. Failure to do so could cause loss of control and injury to yourself and others.

NOTE: AUTO ON/OFF SWITCH: This pressure washer is equipped with an auto start/stop feature. To operate: Set the power switch to the On (I) position. The pump will pressurize and shut down immediately. Once the trigger of the gun is depressed, the unit will turn on. The unit will shut off and be in standby mode when the trigger is released.

USING THE SPRAY TIPS

Each of the spray tips has a different spray pattern. Before starting any cleaning job, determine the best spray tip for the job. The following chart offers some general guidelines to help you choose the best spray tip for your application.

OPERATING THE PRESSURE WASHER

Use only detergents designed for pressure washers. Many detergents may require mixing prior to use. Prepare cleaning solution as instructed on the solution bottle.

To clean:

• Pour detergent into the detergent tank.
• Install the black soap tip on the spray wand.
• Start the pressure washer and spray the detergent on a dry surface using long, even, overlapping strokes. To prevent streaking, do not allow detergent to dry on the surface.

To rinse:

• Using the 25° spray tip, spray away from the rinsing surface for approximately 10 seconds to allow any remaining detergent to be flushed from the line.
• Start at the top of the area to be rinsed and work down, overlapping the strokes.

For the most effective cleaning, the spray tip should be between 8 in. and 24 in. from the surface to be cleaned. If the spray is too close, it can damage the surface.

MOVING THE PRESSURE WASHER

To move the pressure washer:

• Turn the pressure washer off. Point the spray wand in a safe direction and pull the trigger to release water pressure.
• Tilt the machine toward you until it balances on the wheels, then roll the machine to the desired position.
