Never use an undersized discharge nozzle.
Only adjust the unloader if needed. Turn the knob slowly counter-clockwise to reduce pressure, or clockwise to increase pressure.
Never operate the unit with broken or missing parts.
WHILE OPERATING
Always check and maintain proper oil levels described in the Maintenance section of this manual.
Always use water that is clear and free from particles
Always point the wand nozzle away from people and animals, the high pressure the unit generates is very dangerous.
Keep the pressure hose connected to the machine and wand while the unit is pressurized.
Never leave the wand unattended while the machine is running.
Always seek emergency medical immediately if any fluid penetrates the skin.
The cut may be deeper and more serious than it appears.
Do not run preheated water into machines not designed for hot water. For hot water, units run a maximum of 180° F water.
Do not secure the wand in the squeezed, “ON” position.
Never use the unit when under the influence of drugs, alcohol, or medication.
Only adjust the unloader if needed. Turn the knob slowly counter-clockwise to reduce pressure, or clockwise to increase pressure..
Do not move the unit by pulling on the hose or electrical cord.
Only operate the machine with sufficient water supply to the pump.
Do not let the machine run with the wand in the not-squeezed, “OFF” position for more than 2 minutes (30 seconds with the water temperature above 80° F).
This causes the bypass water temperature to increase which damages the pump.
Protect your machine from freezing during storage. Follow the instructions to protect your pressure washer from freezing storage temperatures.
Always follow all other guidelines and safety instructions described in this manual.

ASSEMBLY INSTRUCTION

PRE-ASSEMBLY CHECKLIST

The pressure washer should be as close as possible to the water supply.
Locate the pressure washer on a solid, level surface with a gentle slope to prevent water from building up in the work area. Excess water can make surfaces slippery.
Position the unit so the operator has easy access to the pressure washer and its controls.
To prevent damage and excessive hose wear, locate the pressure washer so the hose does NOT extend across traffic areas. Make sure there are no kinks or twists in the hose.
Use extension cords of at least 12-3 gauge for lengths up to 50 feet or 10-3 gauge for lengths up to 100 feet. Check the extension cord to make sure it is not damaged or frayed. The outlet should have an amperage rating of 20 amps or greater and be an independent receptacle.
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 the Buna-N and PVC (polyvinyl) or neoprene covering of the hose.
Do not run acids or hard caustics through the pump.
Check to determine if the water supply can exceed 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 the 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 for cold water units. Or no more than 180° F for hot water units.
ASSEMBLING

Connect the high-pressure hose to the pressure washer with the twist fast coupler and tighten it securely. Fasten the wand and gun together and connect the gun/wand to the high-pressure hose.
**** Tighten all connections and replace worn parts before starting the machine. The sudden release of high-pressure streams may result if connections detach during use. This can cause serious injury. Never disconnect any part of the unit while the machine is running or before relieving system pressure, it is dangerous. Seek medical attention if an injury ever occurs.
Remove the red plug from the pump crankcase and install the black dipstick. Always check that the oil level is full before operating.
Oil level can be checked in two places.
First, on the back side of the pump sight glass, the level should be halfway.
Second, on the dipstick, oil should read between the indentation on the dipstick.

OPERATING INSTRUCTIONS

BEFORE STARTING THE PRESSURE WASHER

Read all safety instructions throughout the manual.
Place the unit on dry, firm, level ground for optimum lubrication of the pump.
Check oil levels prior to each use.
Tighten all hoses and connections. Check parts and replace them if needed.
When the unit is attached to a pressure main and the nozzle is in the low-pressure setting, purge air from the system by squeezing the gun trigger before starting the machine. Let the water run until there is a steady stream of water coming out of the nozzle.

STARTING THE PRESSURE WASHER

Turn on the water supply to the proper GPM flow rate.
Plug the power cord into a properly grounded outlet.
Turn the nozzle to low pressure and squeeze the trigger.
Turn the “ON/OFF” switch to the “ON” position and wait until a constant stream of water comes out. Adjust nozzle sleeves to achieve proper pressure and coverage area.

DURING OPERATION

Observe all safety instructions through this manual.
Do Not allow the machine to run with the wand not squeezed, “OFF”, for more than 2 minutes (30 seconds with the water temperature above 80° F).
**** When the wand trigger is released the pump does not stop pumping. Water is routed through a bypass circuit which builds up heat. If the water temperature becomes too high, damage to the seals, packings, and other parts may result.
Check the pump, connections, and hose for water and oil leaks. Replace worn parts.

STOPPING THE PRESSURE WASHER

Rinse and close the downstream chemical injector.
Turn the motor power switch to the “OFF” position.
Turn off the water supply.
Squeeze the trigger on the wand to relieve the system water pressure and drain as much water as possible.
Spray the backside of the nozzle with a lubricant and work the nozzle back and forth from high pressure to low pressure. This will help keep the nozzle from sticking.
Follow this procedure each time the machine is stopped. Having the nozzle set at low pressure and squeezing the trigger on the gun when you start the unit will reduce the startup load of the unit.

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 the Allen key provided with the unit through the hole in the motor end housing and rotate the motor one revolution clockwise and counter-clockwise.
Remove the key and start the motor. It should start up easily.

MAINTENANCE

Change oil after the first 50 hours of use. Use a SAE20 or 30 non-detergent oil.
After that, change oil every 200 hours, once a year or when it looks milky, more frequently if used in demanding environments.
Changing oil is one of the most important and lease expensive maintenance items, it will prolong the life of your pressure washer.

ROUTINE CHECKS – DO THESE BEFORE EVERY USE

Check water inlet screens for signs of debris.
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 “OFF” and the pressure was relieved from the system!
Check all fittings and connections for leaks and worn areas.

CLEANING TIPS

The gun nozzle supplied with the pressure washer provides optimum cleaning for universal cleaning applications if used properly.
Cleaning agents are most effective when the surface is rinsed first to loosen dirt.
After pre-rinsing to loosen dirt, then clean with 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.
For best spraying results, hold the gun 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. Waving the spray gun aimlessly across the surface wastes water and expensive detergent and prolongs the cleaning process.
If the pressure washer is used to apply wax, the gun should be held further from the surface to optimize the “misting” effect when applying the wax.
For best results, follow the directions supplied by the wax manufacturer.

GUN, WAND AND NOZZLE

Hold the gun/wand in the normal operating position. Turn the nozzle sleeve clockwise for a fan spray and counterclockwise for a stream. (Pull the nozzle sleeve forward for high pressure while pushing the sleeve away from the gun for low pressure). After shutting down the unit and draining the hose, spray a lubricant, such as WD40, on the backside of the nozzle and work the nozzle back and forth from high to low pressure. This will help prevent the nozzle from sticking. Examine nozzle tip for blockage
only with the pressure washer “OFF” and pressure relieved from the systems.

SETTING NOZZLE PRESSURE / CHEMICAL INJECTOR

High Pressure

For high pressure pull back on the nozzle. Make sure to keep all parts of your hand away from coming water.
For low pressure and chemical, suction push the nozzle forward. Keep all parts of your hand away from the outcoming water.
For adjusting the water spray pattern turn nozzle clockwise for a wide spray fan pattern and counterclockwise for a narrow stream spray pattern.

USING THE SOAP INJECTOR

Your pressure washer is supplied with a downstream low-pressure soap/ chemical injector. Soap is added after the water flows through the pump.
The injector is used to add liquids to the water. The injector works only on low pressure.
Draw soap/chemical into the pressure washer, and insert the filter end of the pick-up hose into the soap/chemical. Adjust the nozzle to the low-pressure position. Do Not use powders, granular, high-viscosity detergents, or acidic- based detergents/chemicals in the injector.
To shut down the injector, remove the pick-up hose and filter from the detergent/ chemical tank and place it in a container of clear water. Run water through the entire system to wash out the chemical you were using.

STORING THE PRESSURE WASHER

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

Make sure the unit is “OFF”, the water supply is disconnected and the system pressure has been relieved.
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”.
Squeeze the gun trigger to relieve pressure from the 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.
When preparing the high-pressure hose assembly and water supply to the unit, turn the water on, and squeeze the trigger on the spray gun to send water through the system. Dispose of the anti-freeze/ water solution safely where it will not be harmful to the environment, people or animals.
