Converting the Black + Decker blower into a leaf vacuum (and vice versa) is easy. In blower mode, the fan is covered with a grill cover. This is removed by pressing the spring-loaded release button and pulling the grill cover away from the unit. Then snap the vac tube in place.
Over time, the spark arrestor can become clogged with soot. If the spark arrestor is clogged, the engine may not start. To unclog the spark arrestor, remove it and clean it with a wire brush. You may also replace the spark arrestor.
There are many different reasons why a leaf blower may fail to start, including stale fuel, engine flooding, dirty air filters, faulty spark plugs, defective batteries, blown fuses, and contact issues of the power switch.
Vacuum won`t turn on

Make sure the battery is fully charged, with the vacuum turned off while charging. After many cycles of use or after intense wear, the battery may lose charge over time or wont function at all. Contact Black and Decker for warranty coverage or replace the battery(!!!

If your battery is not charging and the charger is rapid flashing and the battery is warm, it may be too hot- particularly after heavy or continued use. If so, please allow the battery to cool, then reinsert the battery on charger to try charging again.
So who can take advantage of a leaf blower vac? If you have a small yard and are diligent about keeping up with leaves as they fall—or if you want to surgically suck up leaves from around bushes and flower beds—the vacuum mode on your leaf blower can save time and effort.
