Other Storage Tips
1. DO NOT store gasoline from one season to
another unless it’s been treated with fuel sta-
bilizer.

supply and components resulting in poor per-
formance and/or internal damage to engine.
Fuel should be stored in newer approved plas-
tic storage containers.
3. Cover pressure washer with a suitable cover
that does not retain moisture such as a plastic
or plastic coated tarp.
