Winter Storage; Long Term Storage - Briggs & Stratton PowerBoss Operator's Manual

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 its detergent shut-off
valve to "On" position and run pressure washer with
black spray tip. Flush until tank is empty. Turn its
detergent shut-off valve to "Off" position.
3. Follow steps 1-4 in the previous section After Each Use.
4. Use pump saver, Model 6039, to treat pump. This
minimizes freeze damage and lubricates pistons and
seals.
5. If pump saver is not available, connect a 3 ft. (92 cm)
section of garden hose to water inlet adapter. Pour
RV-antifreeze (antifreeze without alcohol) into hose.
Pull recoil handle twice. Disconnect 3 ft. (92 cm) 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.
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.

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.
NOTICE PumpSaver is available as an optional accessory. It
is not included with the pressure washer. Contact the nearest
authorized 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 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.
WARNING Storage covers can be flammable.
• DO NOT place a storage cover over a hot pressure washer.
• Let equipment cool for a sufficient time before placing the
cover on the equipment.
4. Store unit in a clean and dry area.
