Winter Storage
To protect the unit from freezing temperatures:
1. Empty all detergent reservoirs as follows:
a. Disconnect hose connected to chemical inject fitting
on pump. Place end of hose into suitable container.
b. Rotate one of the detergent shut-off valves to “
On
”
position and open that tanks cover. Gravity will
empty tank contents into container.
c. When first tank is empty, repeat step (b) for other
tank, using a different container.
d. Reconnect hose to detergent inject fitting on pump.
Add 0.5 liter of clean fresh water to each tank and
close tanks covers.
2. Flush detergent system by selecting one tank, turning
its detergent shut-off valve to “ On ” position and run
pressure washer with black spray tip. Flush until first
tank is empty. Turn its detergent shut-off valve to “
Off ”
position. Flush other tank the same way.
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-foot (1 m)
section of garden hose to water inlet adapter. Pour
RV-antifreeze (antifreeze without alcohol) into hose.
Pull recoil handle twice. Disconnect 3-foot (1 m) 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.
Change Engine Oil
While engine is still warm, drain oil from crankcase. Refill
with recommended grade. See
Changing Engine Oil in Engine
Maintenance .
Oil Cylinder Bore
• Remove spark plug and pour about 1/2 ounce (15 ml)
of clean engine oil into the cylinder.
• Install spark plug and pull starter handle slowly to
distribute oil.
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 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.
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.
