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:
1. Flush chemical injection hose by placing filter into a pail
of clean water while running pressure washer in low
pressure mode. Flush for one to two minutes.
2. Shut off engine and let it cool, then remove high
pressure and garden hoses. Disconnect spark plug wire
from spark plug.
3. Empty pump of liquids by pulling engine recoil handle
about 6 times. This should remove most liquid from
pump.
4. Use pump saver to prevent corrosion build up and
freezing of pump.
5. Store unit in a clean, dry area.
Protecting the Pump
To protect the pump from damage caused by mineral
deposits or freezing, use PumpSaver to treat pump. This
prevents freeze damage and lubricates pistons and seals.
NOTE: PumpSaver is available as an optional accessory. It is
not included with the pressure washer. Contact the nearest
authorized service center to purchase PumpSaver.
To use PumpSaver, make sure the pressure washer is
turned off and disconnected from supply water. Read and
follow all instructions and warnings given on the PumpSaver
container.
NOTE: PumpSaver will drip from pump after treatment
and will stain wood and concrete.
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.
STORING THE ENGINE
See the engine owner’s manual for instructions on how to
properly prepare the engine for storage.
CAUTION
• Failure to do so will permanently damage your pump and
render your unit inoperable.
• Freeze damage is not covered under warranty.
You must protect your unit from freezing temperatures.
• Always wear eye protection when using PumpSaver.
Read and follow all cautions and warnings on the
PumpSaver can label.

ABOUT YOUR EQUIPMENT WARRANTY
We welcome warranty repair and apologize 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 service would not
apply if equipment damage occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing or improper installation.
Similarly, the warranty is void if the manufacturing date or the serial number on the equipment has been removed or the equipment has been altered
or modified. During the warranty period, the Authorized Service Dealer, at its option, will repair or replace any part that, upon examination, is found to
be defective under normal use and service. This warranty will not cover the following repairs and equipment:
• Normal Wear: Outdoor Power Equipment, like all mechanical devices, needs periodic parts and service 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 and modification, misuse, negligence, accident, overloading, overspeeding, improper maintenance, repair or storage so as,
in our 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, lime, etc.).
• Other Exclusions: This warranty excludes wear items such as quick couplers, oil gauges, belts, o-rings, filters, pump packing, etc., pumps that
have been run without water supplied or damage or malfunctions resulting from accidents, abuse, modifications, alterations, or improper servicing
or freezing or chemical deterioration. Accessory parts such as guns, hoses, wands and nozzles are excluded from the product warranty. Also
excluded is used, reconditioned, and demonstration equipment; equipment used for prime power in place of utility power and equipment used in
life support applications.
