Hi all, In November I added a Dust Deputy to my shop, using a large (5.5 hp) Craftsman shop vac. The vac is about 5 yrs old but has little use. I've been noticing a smell of something hot when running it, as if wood were burning. It doesn't smell like burnt/worn electric motors I have smelled int the past.

I have definitly narrowed it to the vacuum. Is this normal wood dust causing this odor as it goes through the vac, or is the vac dying? I am using 2.25 hose and there is no vacuum system, I just move the hose to each machine. When I emptied the vacuum to dump the dust, it had little to no sawdust in it. This odor has only been happening the last week or 2.

I realize it is most likely a bad vac, but don't want to replace it if this a normal thing with the dust collector.

Thanks

I'm sure you know, a vacuum will labor if something is blocking the hose. I would check to see that the hoses and the dust deputy are clear. You might have sucked up a rag or a slow moving apprentice and it has partially plugged it.

I have a Dust Deputy hooked up to a big Ridged shop vac and haven't had any troubles in three years except when ( like BlasterStumps mentioned ), was when my hose was partially blocked. That only happens when I get carried away with my planer and forget to check it when full.

If the smell is like wood burning could it be fine dust has gotten inside the motor compartment through the cooling vents and is cooking from the motor heat. The coating of dust also contributes to the build up of heat in the motor.

I regularly blow out the motor compartments of my tools that are exposed to fine dust using an air compressor. It is surprising how much dust comes out.
