Can I use this blower as a vacuum?

This unit is a blower/dryer, not a vacuum. It has a blower end and a suction end, but it is designed to blow air. If you need suction, you can attach the hose to the suction end, but the manual warns that if it doesn't clean, the hose may be clogged and should be blown out.

How do I replace the carbon brushes?

Carbon brushes (ABC-3) should be replaced after about 500 hours of use. You will need a long Phillips and long flathead screwdriver. Remove the front endcap, loosen the tab on the wire, remove the mounting bracket, install the tab into the new brush, and replace the bracket. The front motor must be removed to access the rear motor.
