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 o 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.
