ASSEMBLY INSTRUCTIONS
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 should have a Ground Fault Circuit Interrupter (GFCI).
- 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 is capable of exceeding 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.
ASSEMBLING
-
Connect the high pressure hose to the pressure washer with the twist fast coupler and tighten securely. Fasten wand and gun together and connect gun/wand to high pressure hose.
Tighten all connections and replace worn parts before starting the machine. 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 back side of pump sight glass, level should be half way. Second, on dip stick oil should read between the indentation on the dip stick.
OPERATING INSTRUCTIONS
Before Starting the Pressure Washer
- Read all safety instructions throughout the manual.
- Place unit on dry, firm, level ground for optimum lubrication of pump.
- Check oil levels prior to each use.
- Tighten all hoses and connections. Check parts and replace if needed.
- When the unit is attached to a pressure main and the nozzle is in the low pressure setting, purge air from system by squeezing gun trigger before starting machine. Let 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 power cord into properly grounded outlet.
- Turn nozzle to low pressure and squeeze trigger.
- Turn “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 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 theseals, packings and other parts may result. -
Check 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 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 nondetergent
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 least 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 nozzle for debris and signs of extensive wear. Worn nozzle will result in poor performance. Only check nozzle with the motor turned “OFF” and the pressure 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 pressure washer “OFF”
and pressure relieved from system.
Setting Nozzle Pressure / Chemical Injection
High Pressure
-
For high pressure pull back on nozzle. Make sure to keep all parts of hand away from out coming water.
Diagram A
Low Pressure -
For low pressure and chemical suction push the nozzle forward.
Keep all parts of hand away from out coming water.
Diagram B
Fan Spray -
For adjusting the water spray pattern turn nozzle clockwise for wide spray fan pattern and counter clockwise for narrow stream spray pattern.
Diagram C
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.
To draw soap/chemical into the pressure washer, 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, granulars, high viscosity detergents or acidic
based detergents/chemicals in the injector.
To shutdown the injector, remove pick up tube and filter from
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”, water supply is disconnected and 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 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 gun trigger to relieve pressure from system. Disconnect the high pressure hose from the high pressure outlet and put the hose, gun/wand and owners manual in a secure place to prevent unauthorized people from using the machine.
- When preparing to use the pressure washer again, simply reconnect 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.
