| Question | Answer |
|---|---|
| What is the correct fuel/oil mix for my gas chainsaw? | Most McCulloch gas models require a 40:1 ratio (3.2 oz of 2-cycle oil per 1 gallon of fresh unleaded gasoline). Always check your manual. |
| How often should I sharpen the chain? | Sharpen the chain whenever you notice it producing fine sawdust instead of chips, or when you have to push harder to cut. This could be every few hours of use. |
| My chain keeps coming loose. Why? | New chains stretch. Re-tension frequently during the first half-hour of use. Also, check for a worn drive sprocket or bar. |
| Can I use any bar and chain oil? | Use high-quality, specially formulated bar and chain oil for its adhesive properties. In a pinch, vegetable oil is preferable to motor oil, which can be harmful. |
| Where can I buy replacement parts? | Genuine parts are available through authorized McCulloch dealers, some major hardware stores, and reputable online parts suppliers. |
