ASSEMBLY AND OPERATION INSTRUCTIONS

Surface PreparationBefore starting any cleaning task, it is important to inspect the area for objects that could create a hazard. Remove any objects from the work area that could be tripped over, such as toys or outdoor furniture. Ensure that all doors and windows are closed tightly.

Water Supply (Cold Water Only)Only draw cold water through the washer. For use with cold water supply only. Water hose must be at least a 1/2” (13 mm) in diameter. Flow rate of water supply must not fall below 2 GPM (gallons per minute) [9.1 LPM (liters per minute)]. Flow rate can be determined by running the water for one minute into an empty 5-gallon (19 L) container. Measure the volume of water in bucket after one minute. The water supply temperature must not exceed 104°F (40°C).

CAUTION

Never use the pressure washer to draw in water contaminated with solvents (e.g. paint thinners, gasoline, oil, etc.).
Dirt in the water inlet will damage the pressure washer. To avoid this risk, we recommend checking
Always prevent debris from being drawn into the washer by using a clean water source and an additional accessory water filter if required.
To prolong the life of the washer, rest the washer for minutes after every 30 minutes of use.

Attach garden hose to cold water source and turn water on full. The water temperature must not exceed 104o F (40o C) and the supply pressure must be between 40 to 80 PSI.

CAUTION The pressure washer must only be used with clean water. Use of unfiltered water or corrosive chemicals will damage the pressure washer.This pressure washer is not intended to pump hot water. Never connect it to a hot water supply as it could cause injury and will significantly reduce the life of the pump.

OPERATION INSTRUCTIONS

WARNING Risk of injury, do not direct discharge stream at self or other persons.

WARNING Before cleaning any surface, an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results.

Make sure the On/Off switch is on the “Off” position before plugging in the pressure washer, press the switch with mark “O” to ensure it is off.

Completely unwind power cord by pulling and plug the Ground Fault Circuit Interrupter (GFCI) into a power outlet. Indicator should turn red. TEST BEFORE EACH USE. Press the “TEST” button. Red indicator should disappear. Press “RESET” button again for use. Do not use if above test fails.

Ensure the trigger safety latch is released by pushing it down and engage the trigger for a few seconds to discharge the residual pressure in the high-pressure hose.

Turn on the pressure washer by pressing the switch with mark “ “. The washer will run for a few seconds to build up pressure, then will stop on the function of total stop system (TSS).

Depress the trigger until there is a steady stream of water. Before changing spray tip, switch the washer off, depress trigger to release pressure and activate trigger handle safety latch. Change the spray tip as per the recommendation on page 7, if necessary.

CAUTION Make sure spray tip and wand is well locked. Do not move the spray tip while trigger is depressed.

CAUTION If painted surfaces are peeling or chipping, use extreme caution as pressure washer may remove the loose paint from the surface.For most cleaning applications, a forty degree (40o) spray angle is recommended to avoid damage to the surface being sprayed.The pressure of spray on the surface will increase when you move the wand closer to the surface.

CLEANING DETERGENTS DISPENSER

Only use cleaning detergents recommended for pressure washers. Always follow detergent manufacturer’s label recommendations for proper use of detergents or soap. Always protect eyes, skin and respiratory system from detergent if used.

Turn off the pressure washer by pressing the switch with mark “O”, set the trigger safety latch. For storage, drain washer after use by removing water connection, turning on the washer for a few seconds and depressing gun trigger to release remaining water in the pump. Turn off immediately.

CAUTION

Working with detergent ensures a quick soaking of the dirt, and allows the high-pressure water to penetrate and remove the dirt more effectively.To apply detergents you must be operating at low-pressure. This provides a gentle application of detergent, with the pressure equivalent to a garden hose. The high-pressure setting is used for cleaning; you cannot apply detergents when working at high-pressure. Always test detergent in an inconspicuous area before use.

Engage trigger safety lock
Attach the low-pressure spray tip (black) for soap or detergent application. Detergent application will only work with low-pressure spray tip.
Lift up to remove the cap of detergent tank, fill tank with detergent or soap and replace the cap. Apply detergent as instructed by the detergent manufacturer.
Turn on the pressure washer. Depress trigger to operate washer. The liquid detergent will automatically mix with water, and be discharged through the spray tip.
Allow detergent to remain on the surface for a short time before rinsing. Do not allow detergent to dry on surface
Rinse with clean water under high-pressure. On a vertical surface, rinse from the bottom up, then rinse from the top down to avoid streaking. Hold nozzle 6”-8” (15-20 cm) from the cleaning surface, at a 45° angle.
When you have finished using the detergent dispensing system, fill detergent tank with clean water to rinse the system clean. Depress the trigger for one minute at low-pressure so that all detergents remaining in the system are thoroughly flushed out. Remove detergent tank to empty the remaining water, and rinse it until it is thoroughly cleaned.

CAUTION Fail to follow detergent clean procedure will cause the dispensing system to become clogged.Damage may occur to painted surface if chemical is allowed to dry on surface.Wash and rinse a small section at a time. Avoid working on hot surfaces or in direct sunlight.

Never Use:

Bleach, chlorine products and other corrosive chemicals
Liquids containing solvents (i.e., paint thinners, gasoline, oils)
Tri-sodium phosphate products
Ammonia products
Acid-based products

These chemicals will harm the pressure washer and will damage the surface being cleaned.Failure to follow the above instructions will void product warranty

SHUT DOWN AND STORAGE

(If you are not using detergent, go directly to Step 2.) When you have finished using the detergent dispensing system, fill detergent tank with clean water to rinse the system clean. Depress the trigger for one minute at low-pressure so that all detergents remaining in system are thoroughlyflushed out. Remove detergent tank to empty the remaining water, and rinse it until it is thoroughly cleaned.
Turn off water supply and disconnect the garden hose from the faucet and the water inlet on the washer.
Depress the trigger for a few seconds to release any remaining water until water spray stops, turn off washer immediately.
Unplug the Ground Fault Circuit Interrupter (GFCI) from the power outlet and wrap power cord into the cable reel by rotating the reel with hand crank.
For storage, disconnect the high-pressure hose from the trigger handle and wrap hose into the hose reel by rotating the reel with hand crank.
Engage trigger handle safety latch and disconnect the quick – connect wand from trigger handle, disconnect and replace the spray tip to tip holder on the washer, insert the wand into the wand holder.
Store the washer and accessories in a room that does not reach freezing temperatures. Do not store near furnace or other sources of heat as it may dry out the pump seals.

WARNING Turn off water supply and depress trigger to depressurize the washer. Failure to do so could result in personal injury due to discharge of high-pressure water.

OPTIMUM WINTERIZING PROCEDURE

Winterizing your pressure washer will help protect and prolong its life. We strongly recommend you follow the below steps using pump saver*. This will keep the internal parts lubricated, protected from rust, and prevents the pump from freezing.

Connect the pump saver hose onto the inlet adaptor and quick-connect coupling.
Depress button on top of pump saver container.
Continue until fluid exits the pressure hose for 15 seconds.
Remove the hose from pump inlet.

NOTE: Pump saver is not supplied with your pressure washer. It can be purchased where you purchased this product and at most home center stores. For more information call: 1-866-902-9690.

CLEANING AND MAINTENANCE

Water Filter ScreenThe pressure washer is equipped with a water filter screen to protect the pump. If the screen is not kept clean, the flow of water to the pressure washer will be restricted and the pump may be damaged.

To clean inner water screen, remove the inlet adaptor and remove the filter screen from the pump inlet.
Rinse screen until it is free of debris and blockage.
Replace the filter screen and inlet adaptor immediately to prevent any foreign matter from entering the pump.

Main Body CleaningUse only mild soap and damp cloth to clean the main body.

WARNING Never use the pressure washer to clean itself

ConnectionsConnections on pressure washer hoses, trigger handle and spray wand should be cleaned regularly and lubricated with non-water soluble grease. Failure to do so could void the product warranty

Spray Tips OnlyClogging of the spray tips causes the pump pressure to be too high and cleaning is immediately required. Clean the spray tips by carefully inserting the tip cleaning needle provided, or a thin and sharp instrument (i.e. sewing needle) into the tip to remove any dirt deposited.

WARNING To assure product safety and reliability, repairs should be performed by authorized service technician or other qualified service personnel, always use manufacturer replacement parts. Service or repairs made by unauthorized personnel will void the product warranty
