surface.  
• Be extremely careful if you must use the pressure washer from  
a ladder, scaffolding or any other relatively unstable location.  
WARNING  
• The cleaning area should have adequate slopes and drainage to  
reduce the possibility of a fall due to slippery surfaces.  
High pressure spray can cause paint chips or  
other particles to become airborne.  
• Operate this unit on a stable surface.  
• Always wear eye protection when you use this equipment or  
when you are in the vicinity where the equipment is in use.  
WARNING  
DANGER  
Running engine gives off carbon monoxide, an  
odorless, colorless, poison gas.  
Unintentional sparking can result in fire or  
electric shock.  
Some chemicals or detergents may be harmful if  
inhaled or ingested, causing severe nausea,  
fainting or poisoning.  
Breathing carbon monoxide will cause nausea,

• Make sure the black nozzle is installed.  
NOTE: Detergent cannot be applied with the high  
pressure nozzles (White, Green, Yellow, or Red).  
• 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 and 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. Do Not allow the  
detergent to dry on (prevents streaking).  
• Apply a high pressure spray to a small area and then  
check the surface for damage. If no damage is found, you  
can assume it is okay to continue cleaning.  
• Start at the top of the area to be rinsed, working down  
with same overlapping strokes as you used for cleaning.  
• Allow the detergent to soak in between 3–5 minutes  
before washing and rinsing. Reapply as needed to prevent  
surface from drying.  
Automatic Cool Down System  
(Thermal Relief)  
Pressure Washer Rinsing  
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. At this temperature, the system  
engages and cools the pump by discharging the warm  
water onto the ground. This system prevents internal  
damage to the pump.  
WARNING! Be extremely careful if you must  
use the pressure washer from a ladder, scaffolding  
or any other relatively unstable location. Hose  
water pressure builds as you climb. When you press  
the trigger, the recoil from the initial spray can be  
very strong. The high pressure spray could cause  
you to fall if you are too close to the cleaning  
surface.

Nozzle Maintenance  
A pulsing sensation felt while squeezing the spray gun  
trigger may be caused by excessive pump pressure. The  
principal cause of excessive pump pressure is a nozzle  
clogged or restricted with foreign materials, such as dirt,  
etc. To correct the problem, immediately clean the nozzle  
using the tools included with your pressure washer and  
follow these instructions:  
O-ring  
1. Detach spray gun and nozzle extension from high  
pressure hose. Detach nozzle extension from spray  
gun and remove o-ring and screen from nozzle  
extension. Flush the screen, spray gun, and adjustable  
nozzle extension with clean water to clear debris.  
2. If the screen is damaged, the o-ring kit contains a  
replacement in-line filter screen and an o-ring. If  
undamaged, reuse screen.  
1. Shut off the engine and turn off the water supply.  
2. Remove the nozzle from the end of the nozzle  
extension (Figure 17).  
3. Place the in-line filter screen into the threaded end of  
the nozzle extension. Direction does not matter. Push  
the screen in with the eraser end of a pencil until it  
rests flat at the bottom of the opening. Take care to  
not bend the screen.  
Figure 17 — Nozzle Maintenance

PREPARING THE UNIT  
FOR STORAGE  
Water should not remain in the unit for long periods of  
time. Sediments or minerals can deposit on pump parts and  
“freeze” pump action. If you do not plan to use the  
pressure washer for more than 30 days, follow this  
procedure:  
6. Reinstall the nozzle and in-line filter into the nozzle  
extension. Do Not overtighten the nozzle with the  
allen wrench.  
1. Flush detergent siphoning tube by placing the filter into  
a pail of clean water while running pressure washer in  
low pressure mode. Flush for one to two minutes.  
7. Reconnect the nozzle extension to the spray gun.  
8. Reconnect the water supply, turn on the water, and  
start the engine.  
2. Shut off the engine and let it cool, then remove all  
hoses. Disconnect spark plug wire from spark plug.  
9. Test the pressure washer by operating with each of the  
Quick Connect nozzles.  
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.  
O–Ring Maintenance  
Through the normal operation of your pressure washer,  
o–rings, which keep the connections of the hoses and spray  
gun tight and leak–free, may become worn or damaged.  
4. Use PumpSaver to treat pump. This prevents freeze  
damage and lubricates pistons and seals.  
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.  
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

* The warranty period begins on the date of purchase by the first retail consumer or commercial end user, and continues for the period of time  
stated in the table above. "Consumer use" means personal residential household use by a retail consumer. "Commercial use" means all other  
uses, including use for commercial, income producing or rental purposes. Once equipment has been used commercially, it shall thereafter be  
considered to be in commercial use for purposes of this warranty. Used equipment, demonstration equipment and equipment used for prime  
power in place of a utility are not warranted. Accessory parts such as guns, hoses, wands and nozzles are excluded from the product warranty.  
** The gasoline engine and starting batteries are warranted solely by the manufacturers of those products.  
WARRANTY REGISTRATION IS NOT NECESSARY TO OBTAIN WARRANTY ON GENERAC PORTABLE PRODUCTS  
EQUIPMENT. SAVE YOUR PROOF OF PURCHASE RECEIPT. IF YOU DO NOT PROVIDE PROOF OF THE INITIAL  
PURCHASE DATE AT THE TIME WARRANTY SERVICE IS REQUESTED, THE MANUFACTURING DATE OF THE  
EQUIPMENT WILL BE USED TO DETERMINE THE WARRANTY PERIOD.  
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.  
To locate your nearest authorized Generac Portable Products Service Dealer, look at our dealer locator map on  
www.generac-portables.com or call 1-877-544-0982. To speak with a Customer Service representative, call 1-800-317-7833.
