Using the DeWalt DWOAS8HT Hedge Trimmer Attachment is easy. First, attach it to your compatible power head. Then, you can start trimming hedges at different angles thanks to the 135° articulating head. When using it, make sure to wear proper safety gear like gloves and goggles. For maintenance, after each use, clean the blade to remove any debris. You can use a brush to get rid of dirt. Store the attachment in a dry place to prevent rust. The full - metal case is durable, but avoid hitting it against hard objects. Also, if you want to convert it into other outdoor tools, just use the available additional attachments as per the instructions.
