Operating Instructions

Before Starting the Pressure Washer

1. Read all safety instructions throughout the manual.
2. Place the unit on dry, firm ground for optimum lubrication of pump.
3. The pressure washer should be as close as possible to the water supply.
4. Tighten all hoses and connections. Check parts and replace if needed.
5. Check oil levels prior to each use. Oil should cover the indicator line on the dipstick.
6. To prevent damage and excessive hose wear, position the pressure washer so the hose does NOT extend across traffic areas. Make sure there are no kinks or twists in the hose.
7. Check to determine if the water supply to the pressure washer exceeds the output of the pump. The output of this unit is 2.1 gpm (gallons per minute), so the water supply must deliver at least 2.5 GPM.

Calculate gpm flow rate by running the water supply into a pail for one minute. Measure the gallons in the pail. If it is at least 2.5 gallons in the minute, your supply is adequate. Your water supply must be clean and free of debris. Use water with a temperature of less than 140°F.

Note: This unit is supplied with a “Total Stop System” (TSS) that allows the pump to run only when the gun trigger is squeezed. Releasing the trigger will temporarily stop the machine. Squeeze the trigger on the gun to restart the machine. Avoid rapidly squeezing the trigger to prevent damage to the TSS.

Starting the Pressure Washer

1. Turn on the water supply to pump the inlet.
2. Plug the power cord into a properly grounded 20 Amp, 120-volt outlet.
3. Purge air from the system by removing the nozzle and squeezing the gun trigger before starting the machine. Let water run until there is a steady stream of water coming out of the nozzle.
4. Turn the power switch on Pump Unit to the “on” ( I ) position.
5. Squeeze the trigger on the gun to start the machine.

During Operation

• Position the unit so the operator has easy access to the pressure washer and its controls.
• Do not use the pressure washer outdoors if it is raining, and do not spray the motor or any of its connections.
• Do not use chemicals or agents which are not compatible with Buna-N, PVC (polyvinyl), or neoprene covering of the hose.
• Do not use acids or caustic material with this unit. Damage due to use with incompatible material will not be considered for warranty.
• Always test a small area to avoid possible damage to surfaces.

Using Soap Injector

• Your pressure washer Pump Unit is supplied with a downstream low-pressure soap/chemical injector. This is used for adding soap/chemicals to the water after it has flowed through the pump.
• Note: The injector works only with the supplied black soap nozzle. To draw soap/chemicals into the water stream, insert the filter end of the detergent hose into the soap/chemical. Do Not use powders, granular, high-viscosity detergents, or acidic-based detergents/ chemicals in the injector.
• Note: Follow the soap/chemical manufacturer’s instructions for correct dilution ratios.
• To flush the injector, remove the detergent hose and filter from the detergent/chemical tank and place it in a container of clear water. Run water through the entire system to flush out the soap/chemical you were using.

Cleaning Tips

• Chemicals: Cleaning agents are most effective when the surface is rinsed first to loosen dirt. After pre-rinsing to loosen dirt, then clean with the detergent.
• Detergent should be applied from the bottom to the top of the washing area. Apply detergent and allow the detergent to react with the dirt, then rinse from the top to the bottom. This detergent applying and rinsing technique will help to avoid streaks and skips in the washing area.
• Never use more detergent than is necessary to clean the surface.
• Always follow directions supplied by the detergent manufacturer on the container.
• Cleaning: For best results, hold the nozzle 6 – 12” away from the washing surface and use long, slow deliberate side-to-side strokes, similar to using a paint sprayer. This technique will provide the most effective cleaning impact and minimize streaks and skips in the cleaning process.
• Wax: If the pressure washer is used to apply wax, the gun should be held further from the surface to optimize the “misting” effect during application. For best results, follow the directions supplied by the wax manufacturer.

Stopping Pressure Washer

1. If the chemical/soap injector was used, rinse with clean water.
   Note: Flush the chemical line with a new container and clean water until the discharge is clear.

2. Turn the Pump Unit power switch to the “OFF” position.

3. Turn off the water supply.

4. Squeeze the trigger on the wand to relieve the system water pressure and drain as much water as possible.

5. Follow this procedure each time the machine is stopped.

Note: Squeezing the trigger on the gun when you restart the unit will reduce the startup load of the motor.

Maintenance

• Changing oil is one of the most important and least expensive maintenance items. It will prolong the life of your pressure washer.
• Change oil after the first 50 hours of the break-in period, and then every 200 hours or once per year. Demanding environments may require oil changes more frequently.
• To change the oil: Remove the 17mm oil drain plug on the bottom of the Pump Unit. Refill with 10 ounces of SAE20 or 30W Non-Detergent oil.
• Winterizing or long-time storage: Drain all water out of the pump. A flush pressure washer with a 50/50 mix of RV antifreeze and water. Relieve system pressure by squeezing the gun trigger. When ready to use again, flush the pressure washer with clean water to remove antifreeze.
• Note: See pg.12 “Storing the Pressure Washer”

Routine Checks Before Every Use

1. Check the water inlet screens for debris. Clean as needed using water and a toothbrush.
   Note: Damage can occur if run without a filter.

2. Check the nozzle for debris and signs of extensive wear. A worn nozzle will result in poor performance. Only check the nozzle with the motor turned to the “OFF” position and the pressure is relieved from the system!

3. Check all fittings and connections for leaks and worn sealing areas. Replace worn components.

Storing the Pressure Washer

• Severe damage could occur by water freezing inside the components. To prevent costly repairs, follow these steps:

1. Make sure the unit is “OFF,” the water supply is disconnected, and system pressure has been relieved by squeezing the trigger on the gun.

2. Install a suction hose from the pump inlet (garden hose fitting) into a gallon of NON-TOXIC RV anti-freeze. Following operating instructions start the machine and squeeze the trigger on the spray gun allowing the pump to draw anti-freeze through the entire system. Once the anti-freeze appears at the end of the wand, turn the machine “OFF”.

3. Squeeze the gun trigger to relieve pressure from system.
   Disconnect the high-pressure hose from the high-pressure outlet and put the hose, gun/wand and owner’s manual in a secure place to prevent unauthorized people from using the machine.

4. When ready to use the pressure washer again, reinstall the high-pressure hose and water supply hose. Turn the water on and squeeze the trigger on the gun to send water through the system. Dispose of the anti-freeze/water solution safely so that it will not be harmful to the environment, people, or animals.

Starting the Machine After a Period of Non-Use

Long periods of non-use can cause calcium and iron deposits inside the pump. Starting the machine could cause damage to the pump. Insert a flat blade screwdriver through the hole in the motor end housing and rotate the motor one revolution clockwise and
counter-clockwise. Remove the screwdriver and start the motor. It should start up easily.

Power off the machine before starting.
