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.

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
use all of the parts in the kit.
5. Store unit in a clean, dry area.
STORING THE ENGINE
See the engine owner’s manual for instructions on how to
properly prepare the engine for storage.
To remove a worn or damaged o–ring:
• Use a small flathead screwdriver to get underneath the
o-ring and pry it off.
ENGINE MAINTENANCE
See the engine owner’s manual for instructions on how to
properly maintain the engine.
CAUTION! Avoid prolonged or repeated skin
contact with used motor oil. Used motor oil has
been shown to cause skin cancer in certain
laboratory animals. Thoroughly wash exposed areas

CONSEQUENTIAL DAMAGES UNDER ANY AND ALL WARRANTIES ARE EXCLUDED TO THE EXTENT EXCLUSION IS PERMITTED BY
LAW. Some states do not allow limitations on how long an implied warranty lasts, and some states do not allow the exclusion or limitation of

* 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.
