My leaf blower model#LH4500 was packed without the instructions . Can I get instructions from you.

Try a different outlet, maybe the ground fault interrupter tripped on the circuit.

look up the manual for the model you have
it tells you in it what it is ....

I removed the safety switch and banged it on a workbench multiple times while working the switch. Small amounts of dirt came out each time. I did this until I saw no more dirt. I tested the switch periodically during this procedure with a multi-meter. Switch worked intermittently when I first checked it, then worked consistently after "cleaning." Reassembled and the unit started right up!

most leaf blowers usually just plug in to an extension cord and you push the button and away you go, without seeing your specific model, would be hard to say. Some are gas powered

Well, B & D only offer the run of the mill parts for this model.

These guys only have a selection of general parts also. Sorry. Techs consider these tools "disposable" and even the manufacturer and parts suppliers treat it as such.
