Using the Makita 191X78-9 is a breeze. First, make sure you have the Makita 40V max XGT® High-Speed Dust Blower model GSA01. Attach the nozzle quickly and easily to the blower. Then, point the nozzle into the anchor hole you want to clear. Turn on the blower, and the high - speed air will do the job of getting rid of the dust. When you're done, turn off the blower. As for maintenance, it's simple. After each use, wipe the nozzle clean with a dry cloth. Store it in a dry place to prevent rust or damage. Just be careful not to drop or hit the nozzle hard, as it could affect its performance. Also, always follow the safety instructions of the dust blower when using this nozzle.
