Before connecting a water supply hose, be sure the water supply is capable of providing an uninterrupted source of clean, cold water at a minimum rate of 5 gallons per minute (GPM) and 20 pounds per square inch (PSI) of pressure. Once a proper water supply is secured, follow these steps:

1. Verify the inlet screen is free of any dirt or debris and is in place with the convex side facing out.

2. Turn on the water supply and run for 30 seconds to purge any debris from the supply hose. Then, turn off the water supply and thread the water supply hose into the pump inlet.

3. Thread the high-pressure hose onto the pump outlet.

4. Thread the high-pressure hose onto the spray gun.

Running a pressure washer pump without water will severely damage the pump seals and other internal components. Always purge the air from your pressure washer pump before starting the engine.

1. Connect all the hoses by following the steps outlined in the CONNECTING HOSES section of this manual then turn on the cold water source.

2. Aim the spray gun in a safe direction then squeeze and hold the trigger for at least 30 seconds or until the water runs steady and all the air is purged from the pump and hoses.

3. Check hoses and connections for leaks. If leaks are found, turn off the machine, aim the spray gun in a safe direction and squeeze the trigger to relieve any built up pressure in the system. Never attempt to touch a leak in a high-pressure hose or fitting. Never attempt to repair a high-pressure hose.

Using the incorrect nozzle can damage surfaces. Refer to the table below to select the correct nozzle before using the pressure washer. High-pressure spray can damage plants and other surfaces. To avoid causing damage, cover plants before spraying near them, refer to the table, and test surfaces before spraying to make sure they are strong enough to withstand high-pressure spray.

Nozzle Installation:

To place a nozzle into the spray wand, pull the quick-connect coupler back, insert the nozzle, then release the coupler allowing it to snap back in place. Once installed, pull on the nozzle to make sure it is secure.

Use only approved soaps and chemicals; do not attempt to pressure wash with volatile, flammable, or corrosive liquids, and NEVER use bleach.

1. Attach the open end of the soap hose to the barbed fitting on the pump.

2. Place the filtered end of the soap hose into a container of soap.

3. Insert the black nozzle into the spray wand per the Nozzle Installation section of this manual. NOTE: Soaps will not siphon if the black soap nozzle is not installed on the spray wand.

4. After using soap, place the filtered end of the soap hose into a container of clean water and run pressure washer drawing clean water through the hose and pump until the system is thoroughly rinsed. If soap or other chemicals remain in the pump, the pump could be damaged.

Place the pressure washer on a level surface outside in a well-ventilated area before operating. Keep all flammable materials at least five feet away from all sides of the product.

Engine exhaust contains carbon monoxide, an odorless, colorless, poisonous gas. Running an engine indoors will kill you in minutes.

• Never use pressure washer inside a house, garage, or any other kind of enclosure even if doors and windows are open. Run engine outside at least 20 feet (6 meters) away from windows, doors, and vents. Carefully consider wind direction and air currents when using pressure washer outside to avoid breathing in engine exhaust.

• Following the manufacturer’s instructions and recommendations, install battery operated carbon monoxide alarms in any occupied buildings near the running engine.

• If you experience headache, nausea, dizziness, sleepiness, or weakness while pressure washer is running, move to fresh air and seek medical attention immediately.

This engine will have proper engine performance and emission control when it is operated at or below an altitude of 5000 feet (1524 meters). This engine requires a high-altitude carburetor kit to ensure proper engine performance and emission control when operated at altitudes above 5000 feet (1524 meters). Operating the machine with the wrong engine configuration above 5000 feet (1524 meters) may increase its emissions, decrease fuel efficiency, and hurt performance. To obtain a high altitude carburetor kit, contact your nearest authorized service center.

Operating the engine with a high-altitude carburetor jet kit at an altitude below 5000 feet (1524 meters) will cause the engine to run too hot. Overheating the engine could result in serious engine damage. To avoid this hazard, make sure the correct carburetor kit is installed and the air/fuel mixture is set correctly for your altitude.

Before each use, check for loose or damaged parts, leaks, and/or any other condition that may affect proper operation. Repair or replace all damaged and/or defective parts immediately. Always keep all safety guards in place and in proper working order.

Before starting engine, remove any excessive dirt and debris from cooling vents, exhaust, and starter recoil areas. Always operate the pressure washer on a level surface and never move or tip the pressure washer while operating. Use pressure washer only for its intended purpose.

The engine is shipped from the factory without oil. Running the engine without oil will result in severe engine damage. Fill the engine with the recommended oil type before starting.

1. Check oil with pressure washer on a level surface and the engine off.

2. Unscrew the engine oil dipstick and pull it out, then wipe dipstick clean.

3. Place clean dipstick into filler neck but do not thread it in, leave it resting on the filler neck.

4. Remove the dipstick from filler neck and check oil level. Oil level should be at the upper oil limit on the dipstick.

5. If level is low, add the recommended oil to the crankcase until the level reaches the upper limit on the dipstick. See the engine manual for recommended oil.

6. Install the dipstick and tighten cap by threading it into the filler neck.

Refueling Precautions:

Gasoline is highly flammable and gasoline vapors are extremely explosive. Keep gasoline away from flames, sparks, and other ignition sources. Refuel outdoors in a well-ventilated area with the engine stopped and cool. Wipe up any spilled gasoline and allow engine to dry before starting. Keep a fire extinguisher handy while refueling. Do not operate engine with leaks in the fuel system. Do not store gasoline near other flammable materials.

Fuel Check and Fill Procedure:

1. Check fuel with the engine off and pressure washer on a level surface.

2. Remove fuel tank cap, check fuel level, then fill fuel tank if needed. For fuel cap location see the COMPONENT LOCATIONS section of this manual.

3. Do not use gasoline that is older than 30 days. Use only clean and fresh regular unleaded gasoline with a minimum octane rating of 87. Do not mix oil with gasoline. Do not use gasoline that contains more than 10% ethyl alcohol. E15, E20, and E85 are not approved fuels and should not be used.

4. Do not fill the fuel tank above the maximum fuel level to allow room for fuel expansion.

5. Replace fuel tank cap. Never run engine without fuel cap installed.

NOTE: Using a fuel stabilizer (sold separately) when storing gasoline can help prevent problems related to storing ethanol alcohol blended gasoline. Always follow the instructions provided by the fuel stabilizer manufacturer to mix and use correctly.

1. Complete the steps in the OPERATING CHECKLIST, CONNECTING HOSES, and PRIMING THE PUMP sections of this manual before starting the engine. Failure to do so could damage your engine and pressure washer pump. If needed, refer to the engine manual for model specific starting instructions.

2. Turn the engine ignition switch to the ON position.

3. Adjust choke as needed. NOTE: The starting position of the choke will vary depending on the engine temperature. If starting a cold engine, move the choke lever towards the closed position. If starting a warm engine, move the choke lever towards the open position.

4. Pull the recoil slowly until resistance is felt, then pull rapidly to start the engine.

5. Adjust choke as needed. NOTE: Once the engine starts, slowly move the choke lever to the OPEN position as the engine warms. If engine falters, move choke towards the CLOSED position until the engine is warmed up.

Turning off the water supply to your pump with the engine running will damage the pump. To avoid this hazard always turn off the engine before shutting off the water supply.

• PSI – Stands for pounds per square inch and measures the water pressure or stripping power produced by the pressure washer. The higher the PSI number, the greater the pressure and stripping power produced.

• GPM – Stands for gallons per minute and measures the flow rate of the water. The higher the GPM, the greater the flow or rinsing power produced.

• CU – stands for cleaning units. PSI x GPM = CU. Measures performance efficiency of the pressure washer. Generally, the higher the CU, the more powerful and efficient the machine is.

• Read all warnings and instructions in this and all other manuals that came with the pressure washer.

• Remove all toys, bikes, lawn furniture, etc. from the work area if they should not be sprayed.

• Sweep any loose dirt and debris from the surface you will be pressure washing.

• Cover nearby plants to avoid damaging them with pressure washer spray.

• Lay tarps down to collect paint chips and other debris that get blown off by spray. Exterior surfaces of houses built before 1977 may produce lead paint chips that will have to be collected and properly disposed of at a hazardous waste facility.

• Cover or avoid spraying windows as high-pressure spray can break them.

• A wider spray equals faster cleaning, while tighter spray equals deeper cleaning.

• Do not aim the nozzle straight at a surface. Hold the wand at a 45-degree angle to the surface at a distance that cleans well without causing damage.

• Keep the nozzle about 4-feet away from siding to prevent damage to surfaces.

• Start washing siding at the bottom and work your way up, then rinse from the top down.

• Avoid driving water up behind siding.

• Use overlapping strokes for even cleaning.

• Work in smaller areas and do not let soap dry on surfaces.

Always clean the pressure washer with the engine off and cool. To clean the pressure washer, first use an air compressor set at no more than 25 PSI to clear dirt and debris from the pressure washer surfaces, vents, and cooling slots. Then, wipe the exterior clean with a damp cloth.

NOTICE: Water can damage the pressure washer engine components if allowed to enter through cooling slots or other holes. To avoid engine water damage, do not use a pressure washer, garden hose, or any other sources of running water to clean the pressure washer engine, and never submerge the pressure washer engine in any liquids.

If a nozzle becomes clogged, the pump may pulsate and spray patterns could change. If the nozzle is not cleaned, excessive pressure may develop possibly damaging the pump, or other accessories. Inspect nozzles before using them and follow the instructions in this section for the proper nozzle cleaning procedure.

1. Shut off the pressure washer.

2. Turn off the water supply.
