After Each Use; Winter Storage - Husqvarna Pressure Washer Operator's Manual

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. Flush detergent system by turning its detergent shut-off
valves to "Off" position and run pressure washer with
black spray tip. Flush for one to two minutes.
WARNING The high pressure stream of water that
this equipment produces could cut through skin
and its underlying tissues, resulting in serious
injury and possible amputation.
Spray gun traps high water pressure, even when engine is
stopped and water is disconnected, which could result in
serious 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.
2. Shut off engine, turn off water supply, point gun in a
safe direction, press red button and squeeze trigger to
relieve trapped pressure, and let engine cool.
3. Disconnect hose from spray gun and high pressure
outlet on pump. Drain water from hose, gun, and nozzle
extension. Use a rag to wipe off the hose.
4. Place spray gun, nozzle extension, and spray tips in
accessory holders. Coil high pressure hose on hose
wrap.
5. Empty pump of all pumped liquids by pulling recoil
handle about six times. This should remove most liquid
in pump.
6. Store unit in a clean, dry area.
7. If storing for more than 30 days, see Long Term
Storage on next page.
WARNING Fuel and its vapors are extremely flammable
and explosive which could cause burns,
fire or explosion resulting in death,
serious injury and/or property damage.
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 could ignite fuel vapors.

Winter Storage

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.
To protect the unit from freezing temperatures:
1. Empty all cleaning tanks as follows:
a. Disconnect hose connected to barbed hose fitting
on pump. Place end of hose into suitable container.
b. Rotate one of the detergent shut-off valves to "On"
position and open that tanks cover. Gravity will
empty tank contents into container.
c. When first tank is empty, repeat step (b) for other
tank, using a different container.
d. Reconnect hose to barbed hose fitting on pump.
Add 0.5 liter of clean fresh water to each tank and
close tanks covers.
2. Flush detergent system by selecting one tank, turning
its detergent shut-off valve to "On" position and run
pressure washer with black spray tip. Flush until first
tank is empty. Turn its detergent shut-off valve to "Off"
position. Flush other tank the same way.
3. Follow steps 2-5 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.
