Fuel  
IMPORTANT: It is important to prevent gum deposits  
from forming in essential fuel system parts, such as the  
carburetor, fuel filter, fuel hose or tank during storage.Also,  
experience indicates that alcohol–blended fuels (called  
gasohol, ethanol or methanol) can attract moisture, which  
leads to separation and formation of acids during storage.  
Acidic gas can damage the fuel system of an engine while in  
storage.  
• Before you connect your garden hose to the water inlet,  
inspect the inlet screen (Figure 5). Clean the screen if it  
contains debris or have it replaced if damaged. DO NOT  
RUN THE PRESSURE WASHER IF THE SCREEN IS  
DAMAGED.  
Figure 5 — Connect the Garden Hose to Water Inlet  
Inspect inlet  
screen, Do Not  
use if damaged;  
clean if dirty.  
To avoid engine problems, the fuel system should be  
emptied before storage of 30 days or longer. See “Storage”  
on page 12. Never use engine or carburetor cleaner  
products in the fuel tank or permanent damage may occur.  
Connect Hose and Water Supply to  
Pump  
IMPORTANT:You must assemble the nozzle extension  
to the spray gun and attach all hoses before you start the  
engine. Starting engine without all hoses connected and  
water supplied will damage the pump.  
• Run water through your garden hose for 30 seconds to  
clean out any debris.  
IMPORTANT: Do Not siphon standing water for the  
water supply. Use ONLY cold water (less than 100°F).  
• Uncoil the high pressure hose and attach one end of the

• Allow the detergent to "soak in" for 3-5 minutes before  
How to Use theTurbo Nozzle  
washing and rinsing. Reapply as needed to prevent  
surface from drying. Do Not allow the detergent to dry  
on (prevents streaking).  
The turbo nozzle rotates the high pressure stream in a  
rapid circular pattern.The high pressure spray is most  
effective when the tip of the nozzle extension is held  
between 8 to 24 inches from the surface being cleaned.  
IMPORTANT:You must flush the chemical injection  
system after each use by placing the filter into a bucket of  
clean water, then run the pressure washer in low pressure  
for 1-2 minutes.  
Always start the turbo nozzle at a distance, gradually  
getting closer to the surface until you get the cleaning  
force you want.  
Pressure Washer Rinsing  
WARNING!The turbo nozzle produces an  
extremely high pressure spray which is capable of  
removing paint and cutting holes through surfaces if  
held too close.Always make sure the surface you  
will clean will not be damaged by the high pressure  
spray by testing in a hidden area.  
WARNING! Be extremely careful if you must use  
the pressure washer from a ladder, scaffolding or any  
other relatively unstable location. Pressure in a  
running washer builds as you climb.When you press  
the trigger, the recoil from the initial spray could  
cause you to fall.The high pressure spray could also  
cause you to fall if you are too close to the cleaning  
surface.  
NOTE:You cannot apply detergent with the turbo nozzle.  
Applying Detergent with the  
Adjustable Nozzle  
IMPORTANT: Use soaps designed specifically for  
pressure washers. Household detergents could damage the  
pump.  
For Rinsing:  
• Slide the nozzle backward to high pressure, press the  
trigger and wait for the detergent to clear.  
NOTE:You can also stop detergent from flowing by simply  
removing detergent siphoning tube from bottle.  
CAUTION!You must attach all hoses before you start  
the engine. Starting the engine without all the hoses  
connected and without the water turned ON will damage  
the pump.  
• Keep the spray gun a safe distance from the area you  
plan to spray.  
• Apply a high pressure spray to a small area, then check  
the surface for damage. If no damage is found, it is okay  
to continue cleaning.  
To apply detergent, follow these steps:  
• Review the use of adjustable nozzles.  
• Prepare the detergent solution as required by the job.  
• Start at the top of the area to be rinsed, working down  
with same overlapping strokes as you used for washing  
and applying detergent.  
• Place the filter end of the detergent siphoning tube into  
the detergent container.  
CAUTION! Keep the detergent siphoning tube from  
coming in contact with the hot muffler.  
Automatic Cool Down System  
(Thermal Relief)  
If you run the engine on your pressure washer for  
3-5 minutes without pressing the trigger on the spray gun,  
circulating water in the pump can reach a temperature  
between 140–145°F.When the water reaches this  
temperature, the automatic cool down system engages and  
cools the pump by discharging the warm water onto  
the ground. This system prevents internal damage to the  
pump.  
• Slide the adjustable nozzle forward to low pressure  
mode. Detergent cannot be applied with the nozzle in  
high pressure position.  
• Make sure the garden hose is connected to the water  
inlet. Check that the high pressure hose is connected to  
the spray gun and the pump. Start the engine.  
• Apply the detergent to a dry surface, starting at lower  
portion of area to be washed and work upward, using  
long, even, overlapping strokes.

the high and in the low positions.  
2. Shut off the engine and let it cool, then remove high  
pressure and garden hoses. Disconnect spark plug wire  
from spark plug.  
O–Ring Maintenance  
Through the normal operation of your pressure washer,  
o–rings are used to keep the connections of the hoses and  
spray gun tight and leak–free.These o-rings may become  
worn or damaged.  
3. Empty the pump of all pumped liquids by pulling the  
recoil handle about 6 times.This should remove most  
of the liquid in the pump.  
4. Use PumpSaver to treat pump.This prevents freeze  
damage and lubricates pistons and seals.  
An O–Ring Maintenance Kit is provided with your pressure  
washer. It includes replacement o-rings, rubber washer and  
water inlet filter. Refer to the instruction sheet provided in  
the kit to service your unit’s o-rings. Note that you will not  
use all of the parts in the kit.  
NOTE: If PumpSaver is not available, draw RV antifreeze  
(non-alcohol) into the pump by pouring the solution into a  
3-foot section of garden hose connected to inlet adapter  
and pulling recoil handle twice.  
To remove a worn or damaged o–ring:

About your equipment warranty:  
Generac Portable Products welcomes warranty repair and apologizes to you for being inconvenienced.Any Authorized Service Dealer may perform  
warranty repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service may not be appropriate. For example,  
warranty would not apply if equipment damage occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing or improper  
installation. Similarly, warranty is void if the serial number of the equipment has been removed or the equipment has been altered or modified.  
If a customer differs with the decision of the Service Dealer, an investigation will be made to determine whether the warranty applies.Ask the  
Service Dealer to submit all supporting facts to its Distributor for review. If the Distributor decides that the claim is justified, the customer will be  
fully reimbursed for those items that are defective.To avoid misunderstandings that might occur between the customer and the Dealer, listed  
below are some of the causes of equipment failure that the warranty does not cover:  
Normal wear:  
Outdoor Power Equipment, like all mechanical devices, needs periodic parts, service and replacement to perform well.This warranty  
does not cover repair when normal use has exhausted the life of a part or the equipment.  
Installation and Maintenance:  
This warranty does not apply to equipment or parts that have been subjected to improper or unauthorized installation or alteration,  
misuse, negligence, accident, overloading, overspeeding, improper maintenance, repair or storage so as, in Generac Portable Products'  
judgment, to adversely affect its performance and reliability.This warranty also does not cover normal maintenance such as adjustments,  
fuel system cleaning and obstruction (due to chemical, dirt, carbon or lime, etc.).  
Other Exclusions:  
Also excluded from this warranty are wear items such as quick couplers, oil gauges, belts, o-rings, filters, pump packing, etc., pumps  
which have been run without water supplied or damage or malfunctions resulting from accidents, abuse, modifications, alterations, or  
improper servicing or freezing or chemical deterioration.  
Warranty is available only through service dealers authorized by Generac Portable Products.This warranty does not apply to  
service by any other entity.
