A Warning; Read Owner’s Manual. Do not attempt to operate equipment until you have read Owners Manualfor Safety, Operation, and Maintenance Instructions,
Note: Included with your unit is a video cassette that demonstrates how to operate your pressure washer. If you have a video cassette recorder you should view the video before operation.
A Warning: Never adjust spray pattern when spray ing. Never put hands in front of spray nozzle to adjust spray pattern because you could be injured.
How To Use Your Pressure Washer
On the end of your spray gun is a nozzle that you can twist from side to side. With the adjustable nozzle you can adjust the nozzln.to either high pressure or low pressure.
•Turn the nozzle in a counter clockwise direction to achieve low pressure. Turn nozzle clockwise for high
pressure.
•For most effective cleaning, keep spray nozzle between 8 and 24 inches of cleaning surface.
IMPORTANT; If you get spray nozzle too close, especially on high pressure, you may damage the cleaning surface.
•The pressure control knob Is located on the pump. You can increase the pressure by turning the knob clockwise or decrease the pressure by turning the knob counterclockwise.
NOTE: The maximum pressure for the unit is factory adjusted. Do not attempt to adjust beyond this factory setting.
Using Soaps/Chemicals
IMPORTANT: Use soaps and chemicals that are designed specifically for use with pressure washers, to apply soap/chemicals follow these steps: •
• Prepare the soap/chemical as required by your job.
insert soap/chemical tine into your container (soap/chemicals not included).
NOTE: The first step involves applying an appropriate soap/chemical solution to penetrate and loosen grime. The soap/chemical applied at low pressure to avoid splashing, over spray and waste. Leave the solution on surface for 3 to 5 minutes to allow solution to work.
NOTE: The second step involves cleaning the surface you have prepared with the pressure washer and then rinsing it clean.
•Turn the adjustable nozzle counter clockwise to low pressure mode. Soap/chemicals cannot be applied with nozzle in high pressure position.
•Review the use of the adjustable nozzle.
•Connect garden hose to water inlet (see ’To Start Your Pressure Washer”), check that high pressure hose is connected to spray gun and pump (see Assembly), and start engine.
•Apply soap/chemicals to dry surface, starting bottom and working up.
•Allow the soap/chemicals to soak in between 3-5 minutes before washing and rinsing.
•For cleaning, start at lower portion of area to be washed and work upward, using long, even over lapping strokes.
Your pressure washer is equipped with a chemical injector adjustment knob. With the knob fully opened you will get a 7 to 1 water to chemical ratio. With knob fully closed you will get no chemical draw. Turn knob in counterclockwise direction to achieve more chemical draw and clockwise for less chemical draw.
After using the pressure washer, it is recommended the pump, chemical injector and chemical line be flushed with clear water. To do so, simply place chemical injector hose in water and siphon for 1 tflH minutes.
stopping Your Pressure Washer
A CAUTION: Do not run pump without the water supply connected and turned on. Failure to do so will result in pump damage.
*To turn pressure washer off place the on/off switch to the OFF position.
•Simply shutting OFF engine will not release pressure in the system. Squeeze the trigger on the spray gun for about 3 seconds to relieve pressure. Spray stream wilt decrease in length.
IMPORTANT: This unit is equipped with a thermal relief valve. If unit is allowed tp run for several minutes without pressing the trigger on the spray gun, several drops of water may be released through this valve to cool the unit. The heated water will be purged from the bottom of the pump.
BEFORE STARTING THE ENGINE
To operate the engine you will need to do the following.
A CAUTION: Always check engine oil level before every start. Running engine low of oil or out of oil could result in serious damage.
A CAUTION: Always check pump oil level before every start. Running pump low on oil could result in pump damage.
Adding Pump Oil
Before running the high pressure washer, check the pump oil level by viewing the sight glass on the side of the pump. When properly filled, the oil will be at the half way point marked by the two triangles. Your pressure washer pump is shipped with oil. Add oil only if oil level is lower than the half way point on the sight glass. Do not overfill. Use 30 weight non-detergent oil If necessary.
A CAUTION: Do Not use engine oil that has been shipped with your unit in your pump. Engine oil is detergent and your pump uses a non-detergent oil Detergent oil can cause damage to your pump.
Engine Oil
Your unit has been shipped without oil in the engine. A bottle of SAE 30 weight oil is included in the carton. Remove oil dip stick located on the side of engine. The oil dip stick is clearly marked with a lines that tells you when unit has enough oil. Do not fill above this point. Pour slowly.
NOTE: When adding oil to the engine crankcase, use a high quality detergent oil classified “For Service SF, SG, SH rated SAE 30 weight Use no special addi tives. Select the oil’s viscosity grade according to your expected operating temperatures.

101K-3Ü
ftTAHUMGTCMPSaATURE WnCtWTEDSEFORCNEXTOtLCHWtQE
Air cooled engines run hotter than automotive engines. The use of multi-viscosity oil such as {10W-30, etc.) in ambient temperatures above 40“F (4*C) wilt result in higher than normal oil consumption. If multi-viscosity oil is used, check the oil level more frequently to prevent any posssible engine damage due to lack of lubrication.Use of SAE30 oil below 40“F (4*C) wilt result in hard starting and possible engine damage due to inadequate lubrication.
Gasoline
Your pressure washer engine is 4 cycle. Use unleaded fuel only.
A CAUTION: Do not overfill the fuel tank. Always allow room for fuel expansion.
A WARNING: Never fill fuel tank indoors. Never fill fuel tank when engine Is running or hot. Do not smoke or have open flame when filling fuel tank.
Use clean, fresh, regular unleaded gasoline with a minimum of 85 octane. Do not mix oil with gasoline. If unleaded fuel is not available, leaded fuel may be used-
IMPORTANT: it is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel filter hose or tank during storage. Also, experience indicates that alcohol-blended fuels (called gasoho! or using ethanol or methanol) can attract mois ture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
NOTE: Never start pressure washer without water source turned on and connected to pressure washer.
To Start Your Pressure Washer
Make sure fuel shutoff valve is turned to the open
position.
OPENED
CLOSED
•Remove gas cap
•Add unleaded gasoline, slowly, to fuel tank.
•Do not overfill.
Connect garden hose to the water inlet on the pressure washer. Tighten by turning water inlet counterclockwise.
Connect high pressure hose to discharge on pump. Connect the garden hose to the water spout
and turn water supply on.
Squeeze trigger on pressure washer wand to relieve air pressure caused by turning on the water. Water will spew out of the gun in a thin stream. This will make it easier to start the engine.
Engage the safety latch on the spray gun. This locks the trigger in place and keeps you from accidentally spraying a high pressure stream.
On the engine there is a choke/run lever. Place lever to the choke position.
CHOKE
LEVER
On the engine there is a throttle control lever. Place throttle to the rabbit position. Always start engine with throttle in the rabbit position. Place on/stop switch to the “on" postion.
Grasp the starter grip and pull slowly until resistance is felt, then pull firmly to start engine.
When engine starts, gradually move choke lever to RUN position.
If engine does not start after 5 pulls, place choke back to run position.
For hot engine starts make sure choke lever is in
the run position. Make sure fuel shut off valve is open and throttle is in the rabbit position.
NOTE: If any leaks are present shut unit down and tighten fittings.
