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:
I. Flush detergent siphoning tube by placing the filter into
a pail of clean water while running pressure washer in
low pressure mode. Flush for one to two minutes.
2. Shut off the engine and let it cool, then remove high
pressure and garden hoses. Disconnect spark plug wire
from spark plug.
3. Empty the pump of liquids by pulling the engine recoil
handle about 6 times. This should remove most of the
liquid in the 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 PumpSaverto treat pump. This
prevents freeze damage and lubricates pistons and seals.
NOTE: PumpSaver,model number 01559, is availableasan
optional accessory.It is not includedwith the pressurewasher.
CAUTION
• Failure to do so will permanently damageyour pumpand
render your unit inoperable.
• Freeze damage is not covered under warranty.
CAUTION
Always wear eye protection when using 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: PumpSaverwill drip from pump after treatment
and will stain wood and concrete.

(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.
