WINTER STORAGE
NOTICE:
You must protect your unit from freezing
temperatures.
• Failure to do so will permanently damage your pump and render
your unit inoperable.
• Freeze damage is not covered under warranty.
To protect the unit from freezing temperatures:
1. Empty cleaning tank as follows:
a. Disconnect hose connected to injection fitting on
pump. Place end of hose into suitable container.
b. Rotate detergent shut-off valve to “ On ” position and
open the tanks cover. Gravity will empty tank
contents into container.
c. Reconnect hose to injection fitting on pump. Add
0.5 quart of clean fresh water to cleaning tank and
close tanks cover.
2. Flush detergent system by turning detergent shut-off
valve to “
On ” position, rotate PrecisionSpray™ Selector
to a low pressure position and run pressure washer.
Flush until cleaning tank is empty. Turn its detergent
shut-off valve to “
Off ” position.
3. Follow steps 2-5 in the previous section After Each Use .
4. Use pump saver, available at Sears retail item
7174403GS, to treat pump. This minimizes freeze
damage and lubricates pistons and seals.
5. If pump saver is not available, connect a 3-foot section
of garden hose to water inlet adapter. Pour
RV–antifreeze (antifreeze without alcohol) into hose. Pull
recoil handle twice. Disconnect 3-foot hose.
6. Store unit in a clean, dry area.
LONG TERM STORAGE
If you do not plan to use the pressure washer for more than
30 days, you must prepare the engine and pump for long
term storage.
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.
Protect Fuel System
Fuel Additive:
Fuel can become stale when stored over 30 days. Stale fuel
causes acid and gum deposits to form in the fuel system or
on essential carburetor parts. To keep fuel fresh, use Briggs
& Stratton FRESH START® fuel stabilizer, available as a
liquid additive or a drip concentrate cartridge.
There is no need to drain gasoline from the engine if a fuel
stabilizer is added according to instructions. Run the engine
for 2 minutes to circulate the stabilizer throughout the fuel
system. The engine and fuel can then be stored up to
24 months.
If gasoline in the engine has not been treated with a fuel
stabilizer, it must be drained into an approved container. Run
the engine until it stops from lack of fuel. The use of a fuel
stabilizer in the storage container is recommended to
maintain freshness.
Change Oil
While engine is still warm, drain oil from crankcase. Refill
with recommended grade. See
Changing Engine Oil .
Protect Pump
To protect the pump from damage caused by mineral
deposits or freezing, use PumpSaver, retail item 7174403GS,
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 your local
Sears service center to purchase PumpSaver.
NOTICE:
You must protect your unit from freezing
temperatures.
• Failure to do so will permanently damage your pump and render
your unit inoperable.
• Freeze damage is not covered under warranty.
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.
Other Storage Tips
1. DO NOT store fuel from one season to another unless it
has been treated as described in

2. Replace fuel container if it starts to rust. Rust and/or dirt
in fuel can cause problems if it’s used with this unit.
3. Cover unit with a suitable protective cover that does not
retain moisture.
4. Store unit in a clean and dry area.
STORAGE
WARNING: Storage covers can be flammable.
• DO NOT place a storage cover over a hot pressure washer.
