pressure.

7. Let the pressure washer cool down.

8. Disconnect the high-pressure hose and water inlet

hose.

9. Drain the hoses, spray gun and nozzle extension.

10. Engage the trigger lock on the spray gun.

11. Wipe off remaining water with a clean, dry rag.

LONG-TERM STORAGE

WARNING

Never store a pressure washer with
fuel in the tank indoors or in a poorly
ventilated area where the fumes can
come in contact with an ignition source
such as a: 1) pilot light of a stove, water
heater, clothes dryer or any other gas
appliance; or 2) spark from an electric
appliance.

NOTICE

Gasoline stored for as little as 60 days can go bad,
causing gum, varnish and corrosive buildup in fuel
lines, fuel passages and the engine. This corrosive
buildup restricts the fl ow of fuel, preventing an engine
from starting after a prolonged storage period.

Proper care should be taken to prepare the pressure
washer for any long-term storage.

Storage Procedure for 1 – 3 Months

1. Clean the pressure washer as outlined in After

Each Use on page 45.

2. Add a gasoline fuel stabilizer to the fuel tank. Follow

the recommended procedure of the fuel stabilizer
manufacturer for correct amount of stabilizer to add.

Storage Procedure for Greater Than 3
Months

1. Clean the pressure washer as outlined in After

Each Use on page 45.

2. Drain all gasoline from the fuel tank as best as

possible.

3. Connect a hose to the water inlet fi tting and turn on

hose.

4. Start the engine and allow the pressure washer to

run until all the remaining gasoline in the fuel lines
and carburetor is consumed and the engine shuts
off.

5. Clean the pressure washer as outlined in After

Each Use on page 45.

6. Change the oil (see Adding Engine Oil on page

38).

7. Remove the spark plug (see Spark Plug Maintenance

on page 43) and place about 1 tablespoon of oil
in the spark plug opening. While placing a clean rag
over the spark plug opening, slowly pull the recoil
handle to allow the engine to turn over several times.
This will distribute the oil and protect the cylinder wall
from corroding during storage.

8. Replace the spark plug (see Spark Plug

Maintenance on page 43).

9. Move the pressure washer to a clean, dry place for

storage.

WINTER STORAGE

1. Follow steps 1 through 11 in After Each Use on

page 45.

2. Store the hoses, spray gun and nozzle extension.

4. Connect a 3-foot (1-meter) section of garden hose

to the water inlet hose fi tting.

5. Using a funnel, pour 6 oz (177 mL) of RV antifreeze

into the hose.

NOTICE

Use only RV antifreeze. Any other antifreeze can
damage the pump.

6. Slowly pull the recoil handle several times, until

antifreeze comes out of the high-pressure fi tting of
the pump.

7. Remove the 3-foot (1-meter) garden hose.

8. Reconnect the spark plug wire.

9. Store the pressure washer in a clean, dry place.
