Using this DeWalt chainsaw is easy. First, make sure the DCB609 battery is fully charged using the DCB115 charger. Then, put on safety gear like gloves and goggles. Attach the bar sheath when not in use for protection. When starting a job, use the onboard wrench for quick chain adjustment. Keep in mind that the chain brake is there to protect you from kick - back, so always be aware of it. During use, the auto - oiling feature will keep the chain and bar lubricated, but check the oil level regularly. For maintenance, after each use, clean the chainsaw to remove any sawdust or debris. Also, check the chain tension and sharpness. If the chain is dull, it's time to replace it. Store the chainsaw in a dry place to prevent rust.
