2. Long-term: Drain fuel completely or add fuel stabilizer.
3. Run engine dry: After adding stabilizer, run engine for 5 minutes.
4. Clean thoroughly: Remove sawdust, dirt, and resin.
5. Remove chain: Clean and oil chain, store separately.
6. Storage location: Cool, dry place away from ignition sources.
