Using your DeWalt 60V MAX 18-inch Brushless Cordless Chainsaw is easy. First, make sure the battery (DCB609, sold separately) is fully charged. Then, attach the bar sheath and use the tensioning tool to adjust the chain if needed. When you're ready to cut, hold the chainsaw firmly and start it. Use the onboard wrench for quick chain adjustments during use. For safety, always wear protective gear like gloves and goggles. The chain brake provides extra protection against kickback, so be aware of its function. To maintain your chainsaw, keep it clean and dry after use. The auto - oiling feature ensures continuous lubrication, but check the oil level regularly. If the saw is not going to be used for a long time, store it in a cool, dry place. Also, make sure to follow all safety instructions provided by DeWalt.
