Winter Storage
To protect the unit from freezing temperatures:
.
1. Use Pump Saver to treat pump. This minimizes freezing damage and
lubricates pistons and seals. Contact your local dealer for Pump Saver
Solution. To use Pump Saver, make sure the pressure washer is turned
off and disconnected from supply water. Read and follow all
instructions and warnings given on the Pump Saver container.
2. If pump saver is not available, connect a 3 ft. section of garden hose to
water inlet adapter. Pour RV-antifreeze (antifreeze without alcohol) into
hose. Pull recoil handle twice. Disconnect 3 ft. hose.
3. Store unit in a clean, dry area (heated area preferred).
Long Term Storage
If you do not plan to use the pressure washer for more than 30 days, you
must prepare the motor and pump for long term storage.
Storing the Motor
See the engine operator’s manual for instructions on how to properly
prepare the engine for 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.
Other Storage Tips
1. Cover unit with a suitable protective cover that does not retain
moisture.
WARNING
Storage covers can be flammable.
• DO NOT place a storage cover over a hot pressure washer.
• Let equipment cool for a sufficient time before placing the cover on
the equipment.
2. Store unit in a clean and dry area.
