MAINTENANCE AND STORAGE
Engine Stored for Over 30 Days

4. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.

Winter Storage

Protect your semi-trash pump parts from freezing.

2. Make sure semi-trash pump hose is free of all water
before storing for winter.

cm) of garden hose or equivalent. See diagram below.
5. Pour the antifreeze into the funnel, then pull on the
engine recoil starter to create suction in the pump
housing. Pull the recoil several times until antifreeze
comes out of the pump outlet.
