STORAGE
Winter Storage
To protect the unit from freezing temperatures:
1. Follow steps 1-5 in the previous section After Each Use.
2. Use pump saver, Model 6039, to treat pump. This
minimizes freeze damage and lubricates pistons and seals.
3. If pump saver is not available, connect a 3 ft. section of
garden hose to water inlet adapter. Pour RV-antifreeze
(antifreeze without alcohol) into hose. Pull recoil handle
twice. Disconnect 3 ft. hose.
4. 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.
Protect Fuel System
Fuel Additive:
Fuel will become stale when stored over 30 days. Stale fuel
causes acids and gum deposits to form in the fuel system or on
essential carburetor parts. Prior to storage, if gasoline has not
been treated with a fuel stabilizer, it must be drained from the
engine into an approved container. Then run engine until it stops
from lack of fuel.
When fuel stabilizers are used according to their instructions, there
is no need to drain the gasoline from the engine prior to storage.
Use Briggs & Stratton FRESH START™ fuel stabilizer. Run the
engine for a short time to circulate stabilizer throughout the fuel
system. Engine and fuel can then be stored up to 24 months.
If gasoline is drained, the use of a fuel stabilizer in the storage
container is still recommended to maintain freshness.
Storing the Engine
See the engine operator’s manual for instructions on how to
properly prepare the engine for storage.
Protecting the Pump
To protect the pump from damage caused by mineral deposits or
freezing, use PumpSaver, Model 6039, 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 dealer 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.
Other Storage Tips
1. DO NOT store fuel from one season to another unless it has
been treated as described in Protect Fuel System.
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.
