PREPARING THE UNIT
FOR STORAGE
Water should not remain in the unit for long periods of
time. Sediments or minerals can deposit on pump parts and
“freeze” pump action. If you do not plan to use the
pressure washer for more than 30 days, follow this
procedure:
1. Flush chemical injection hose by placing filter into a pail
of clean water while running pressure washer in low
pressure mode. Flush for one to two minutes.
2. Shut off engine and let it cool, then remove high
pressure and garden hoses. Disconnect spark plug wire
from spark plug.
3. Empty pump of liquids by pulling engine recoil handle
about 6 times. This should remove most liquid from
pump.
4. Use pump saver to prevent corrosion build up and
freezing of pump.
5. Store unit in a clean, dry area.
Protecting the Pump
To protect the pump from damage caused by mineral
deposits or freezing, use PumpSaver to treat pump. This
prevents freeze damage and lubricates pistons and seals.
NOTE: PumpSaver is available as an optional accessory. It is
not included with the pressure washer. Contact the nearest
authorized service center to purchase PumpSaver.
To use PumpSaver, make sure the pressure washer is
turned off and disconnected from supply water. Read and
follow all instructions and warnings given on the PumpSaver
container.
NOTE: PumpSaver will drip from pump after treatment
and will stain wood and concrete.
NOTE: If PumpSaver is not available, draw RV antifreeze
(non-alcohol) into the pump by pouring the solution into a
3-foot section of garden hose connected to inlet adapter
and pulling recoil handle twice.
STORING THE ENGINE
See the engine owner’s manual for instructions on how to
properly prepare the engine for storage.
CAUTION
• Failure to do so will permanently damage your pump and
render your unit inoperable.
• Freeze damage is not covered under warranty.
You must protect your unit from freezing temperatures.
• Always wear eye protection when using PumpSaver.
Read and follow all cautions and warnings on the
PumpSaver can label.
