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 spray gun
in a safe direction, press red button and squeeze trigger
to relieve trapped pressure, release trigger on spray
gun and let engine cool.
2. Disconnect hose from spray gun and high pressure
outlet on pump. Drain water from hose, spray gun, and
nozzle extension. Use a rag to wipe off the hose.
3. Empty pump of all pumped liquids by pulling 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 Long Term
Storage on next page.
Winter Storage
To protect the unit from freezing temperatures:
1. Empty all detergent tanks as follows:
a. Rotate both detergent shut-off valves to “Off”
position.
b. Disconnect detergent siphon hose connected to
barbed hose fitting on pump. Place end of hose into
suitable container.
c. Rotate one of the detergent shut-off valves to “On”
position and open that tanks cover. Gravity will
empty tank contents into container.
d. When first tank is empty, repeat step (c) for other
tank, using a different container.
e. Reconnect hose to barbed hose fitting on pump.
Add 1 pint (0.5 liter) of clean fresh water to each
tank and close tanks covers.
2. Flush cleaning system by selecting one tank, turning its
detergent shut-off valve to “On” position and run
pressure washer with black nozzle. 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.
WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK
• Store away from furnaces, stoves, water heaters, clothes dryers,
or other appliances that have pilot light or other ignition source
because they can ignite fuel vapors.
WARNING
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, press red button and
squeeze spray gun trigger, to release high pressure, every time
you stop engine.
NOTICE
You must protect your unit from freezing temperatures.
• Failure to do so will permanently damage your pump and render
your unit inoperable.
• Freeze damage is not covered under warranty.
