Using the DeWalt 60V MAX FlexVolt Blower and Chainsaw Combo Kit is a breeze. For the blower, just attach the battery, select your desired speed with the variable speed trigger, and start clearing debris. You can use the flat concentrator nozzle for stubborn messes. The speed lock feature lets you keep a consistent speed without holding the trigger all the time. When using the chainsaw, make sure you're in a safe position. Check the chain tension before each use using the tool - free tensioning system. Engage the chain brake when not in use to prevent kickback. For maintenance, keep the blower clean from debris buildup. After each use, wipe it down. For the chainsaw, regularly check the oil level and refill using the quarter - turn oil cap. Also, make sure the bar and chain are properly lubricated by the auto - oil system. When storing, keep both tools in a dry place and charge the battery periodically to maintain its life.
