If your unit is to be stored for a period of time:
1. Clean the entire unit before lengthy storage.
2. Store in a clean dry area.
3. Lightly oil external metal surfaces.

Run engine at least 5minutes after adding stabilizer.

2. Clean air filter.
3. Check entire unit for loose screws, nuts, and bolts. Replace any damaged, broken, or worn parts.
