Using the DeWalt DCCS670B chainsaw is straightforward. First, make sure the chain has enough oil by checking the oil level through the sight window and using the quarter - turn oil cap to refill if needed. Before starting, ensure the chain brake is engaged for safety. To adjust the chain tension, use the tool - free chain tensioning and bar tightening knob to get the right clamping force. When cutting, hold the saw firmly with both hands and let the saw do the work. Don't force it. For maintenance, clean the saw after each use, especially the bar and chain. Check the chain regularly for wear and replace it if necessary. Also, keep the air filter clean. Remember, this saw comes with a 3 - year limited warranty, a 1 - year free service contract, and a 90 - day money - back guarantee. Always follow safety guidelines to prevent accidents.
