6.20.1 — Protect Fuel System
Fuel can become stale when stored over 30 days. Stale
fuel causes acid and gum deposits to form in the fuel sys-
tem or on essential carburetor parts. To keep fuel fresh,
use a 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.
Hearing Protection Recommended.
6.20.2 — Protect Engine
1. Change engine oil.
2. Remove spark plug.
3. Pour a tablespoon (5-10 cc) of clean engine oil into
the cylinder.
4. Pull the starter rope several times to distribute the oil
in the cylinder.
5. Reinstall the spark plug.
6. Pull the starter rope slowly until resistance is felt.
This will close the valves so moisture cannot enter
the engine cylinder. Return the starter rope gently.
6.20.3 — Change Oil
Allow the engine to cool down and then drain oil from
crankcase. Refill with recommended grade. See “Chang-
ing Engine Oil” on page 27.
Hot oil may cause burns. Allow engine to cool
before draining oil. Avoid prolonged or
repeated skin exposure with used oil. Thor-
oughly wash exposed areas with soap.
6.20.4 — Protecting the Pump
To protect the pump from damage caused by mineral
deposits or freezing, use PumpSaver or RV-antifreeze to
treat the pump. This prevents freeze damage and lubri-
cates pistons and seals.
• 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” on page 29.
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.
6.21 — OTHER STORAGE INSTRUCTIONS
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.
Storage covers can be flammable.
• DO NOT place a storage cover over a hot power
washer.
• Let equipment cool for a sufficient time before placing
the cover on the equipment.
4. Store unit in a clean and dry area.
6.22 — TRANSPORTING/TIPPING OF THE
U
NIT
Do not operate, store or transport the unit at an angle
