Winter Storage

NOTE: If pump saver is not available, connect
a 3-foot section of garden hose to water inlet
adapter. Pour RV-antifreeze (antifreeze with-
out alcohol) into hose. Pull recoil handle twice.
Disconnect 3-foot hose.
• Store unit in a clean and dry area.
NOTE: If not using power washer for more
than 30 days, prepare engine and pump for
storage.

Prepare Fuel System for Storage

Fuel stored over 30 days can go bad and
damage fuel system components. Keep fuel
fresh, use fuel stabilizer.
If fuel stabilizer is added to fuel system, pre-
pare and run engine and pump for long term
storage. Run engine for 2 minutes to circulate
stabilizer throughout fuel system. Adequately
prepared fuel can be stored up to 24 months.
NOTE: If fuel has not been treated with fuel
stabilizer, it must be drained into an approved
container. Run engine until it stops from lack
of fuel. Use of fuel stabilizer in fuel storage
container is recommended to keep fuel fresh.
Prepare Engine for Storage
1. Change engine oil.
2. Remove spark plug.
3. Pour tablespoon (5-10cc) of clean engine
oil or spray a suitable fogging agent into
cylinder.
4. Pull starter recoil several times to distrib-
ute oil in cylinder.
5. Install spark plug.
6. Pull recoil slowly until resistance is felt.
This will close valves so moisture cannot
enter engine cylinder. Gently release
recoil.

Change Oil

Change engine oil before storage. See
Change Engine Oil.

Prepare Pump for Storage

Protect unit from freezing temperatures. Fail-
ure to do so will permanently damage pump
and render unit inoperable. Freeze damage is
not covered under warranty.
Protect unit from freezing temperatures as fol-
lows:
1. Shut engine OFF.
2. Turn water supply OFF.
3. Point spray gun in a safe direction, and
squeeze trigger to relieve trapped pres-
sure.
4. Let engine cool.
5. Disconnect hoses from spray gun and
high-pressure outlet on pump. Drain water
from hoses, spray gun, and lance. Use a
rag to wipe off components.
6. Empty pump of all remaining liquids.

7. Turn engine start switch and fuel valve to
OFF.
8. Pull recoil handle approximately six times
to remove remaining liquid from pump.
9. Winterize pump with pump saver. This
minimizes freeze damage and lubricates
pistons and seals.
10. Store unit in a clean and dry area.
NOTE: If pump saver is not available, connect
a 3-foot section of garden hose to water inlet
adapter. Pour RV-antifreeze (antifreeze with-
out alcohol) into hose. Pull recoil handle twice.
Disconnect 3-foot hose.
