Question 1

I want to sand my deck 8ft x 30ft.  Is this belt sander capable of doing the job, or do I have to rent a drum or floor sander?

Accepted Answer

It really depends how bad your deck is.  I refinished a hardwood floor with this sander (app. 15'x10') and it did really good. If I there had been more finish left before I started I would have rented.  The belts I used clogged up quick when sanding the old finish off. I think it's possible for sure but it is a lot of work. I wanted to do my job in steps so renting a floor sander for a month would have been expensive.

Question 2

Does this come with the attachment for mechanical dust extraction as shown in the photograph?

Accepted Answer

Yes, but I have never used this tiny bag.  That would be for small jobs only.  I have done my deck and now I am working on my dock.  I directly hook it to the small size shop vacuum hose (through a piece of single diameter tube adopter I improvised), and dump the dust into a 5 gallon construction bucket, through a piece of low thread count scrap bed sheet, held in place by a bungee cord.  It works just like a shop vacuum because the blower is so strong on the sander that you don't need the additional suction of a shop vacuum, or the weight of it to haul around.  This is still hard work, but you can't get a better tool.

Question 3

is the 9403 120v or 220

Accepted Answer

The 9403 belt sander is 120v electric AC.

Question 4

does this have auto tracking like the 21 inch model? if does it stay tracked?

Accepted Answer

Not sure if it has auto track or not.  However, I have used it for about 100 hours without any problems.  Once I center the new belt it stays there.  In fact it is probably the best 4" belt sander I have used.Its heavy, well built, removes stock quickly, and runs like a champ.  I use it to smooth rough sawn lumber that is too large to get through my planers.
