OneWASH™ Power Washer 29
• It is a violation of California Public Resource Code,
Section 4442, to use or operate the engine on any for-
est-covered, brush-covered, or grass-covered land
unless the exhaust system is equipped with a spark
arrester, as defined in Section 4442, maintained in
effective working order. Other states or federal jurisdic-
tions may have similar laws. Contact the original equip-
ment manufacturer, retailer, or dealer to obtain a spark
arrester designed for the exhaust system installed on
this engine.
• Replacement parts must be the same and installed in
the same position as the original parts.
6.18 — AFTER EACH USE
Water should not remain in the unit for long periods of
time. Sediments or minerals can deposit on pump parts
and freeze pump action. Follow these procedures after
every use:
1. Shut off engine, turn off water supply, point gun in a
safe direction, and squeeze trigger to relieve trapped
pressure, and let engine cool.
The high pressure stream of water that this
equipment produces can cut through skin and
its underlying tissues, leading to serious
injury and possible amputation. Spray gun
traps high water pressure, even when engine
is stopped and water is disconnected, which
can cause injury.
• Keep high pressure hose connected to pump and
spray gun while system is pressurized.
• ALWAYS point spray gun in safe direction and squeeze
spray gun trigger, to release high pressure, every time
you stop engine. Engage trigger lock when not in use.
2. 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 the hose.
3. Empty pump of all pumped liquids. Check that the
engine ON/OFF switch is in the OFF position. Then
pull the recoil handle about six times. This should
remove most liquid in pump.
4. Store unit in a clean, dry area.
5. If storing for more than 30 days, see the “Long Term
Storage” on page 29.

6.19 — WINTER STORAGE
NOTE:
You must protect your unit from freezing tempera-
tures.
• 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. Follow steps 1-3 in the previous section “After Each
Use”.
2. Use pump saver to treat pump. This minimizes
freeze damage and lubricates pistons and seals.
3. If pump saver is not available, connect a 3-foot sec-
tion of garden hose to water inlet adapter. Pour RV-
antifreeze (antifreeze without alcohol) into hose. Pull
recoil handle twice. Disconnect 3-foot hose.
4. Store unit in a clean, dry area.
6.20 — LONG TERM STORAGE
If you do not plan to use the power washer for more than
30 days, you must prepare the engine and pump for long
term storage.
