Mystery-Bosch4000

Laumonster | Posted in Tools for Home Building on June 7, 2006 10:36am

I don’t know where you were plugged in. But ,  one time we were on site and some thing similar happened ,my friend’s saw fired up like a jet airliner and fried itself. The reason was , that some rookie unplugged my friend  from the spider box and plugged him back into the 220.    uh, oops.

    Well, it couldn't be the belt slippin' because there ain't none.

    My bet is that it's a problem with the electronic feedback circuitry that is supposed to keep the speed constant, or the RPM sensor.  Also could be the soft start.  Good idea to get it taken care of under warranty.

    Did you get any results?

    Inquiring minds want to know.

    The circuit board for this model has been known to fail--do a search of these archives and you'll find others who had bad boards.  I would expect it to fail a month or so after the warranty expires...

      Did u buy it with a credit card. Both my gold and platinum has xtended warranty clauses which dbl manufactures warranty and has saved my butt several times.

    I recently had two Bosch 4000 saws both have problems with the circuitry.  The store finally gave me the new Makita and I must say its impressive.

    I have heard a few problems lately with the Bosch saws which is strange considering all the great reviews.

      My tool supply think it's the soft start module failing.  So far, no call backs or repair alerts.  If you were stuck w/o immediate recourse, bypassing the soft start would let you run.  Jumping somewhere in the brush connections could do it.A great place for Information, Comraderie, and a sucker punch.

      I know the Bosch tablesaw is a fan favorite around here, so I say this with some trepidation...... everytime I walk into the my tool supplier's store and mosy back near the repair shop, there are at least a 1/2 dozen Bosch tablesaws waiting for repair, compared with a random sampling of the other brands.  The majority of TS's in for repair are always Bosch. 

      I can't say I know why and never bothered to ask.  Maybe it's just a percentage game where more guys own the Bosch than any other brand so naturally there's more of them around to break down.  Never the less, I see what I see.

      That being said.  I'd probably still buy one if my Ridgid ever craps out!  I've come to believe that none of the tools available are perfect, or even great for that matter.  I just pick the ones that best fit what we do and have decent track record.  Shoot, my Hilti recip saw that I paid about $250 for just broke down to the tune of a $125 repair and I really can't say it's worked all that hard.  You take the good with the bad, I guess.View Image

        Another reason for reading here.  And don't feel intrepid, it's info on what's seen that pays off both to us and to the manufacturer once we get the word out.

        I've had nothing but good luck with my TS.  Few yrs old now and the only bad news I'll give is don't buy the dust bag, and keep an eye on cleaning the raise/lower gear.

        Z, the fella at Electric too mentioned hot use might be the culprit.  Never had a problem running alot of stock.If you can find that module, see if there's alot of sawdust caked around it.  Since they didn't change the saw much over the years, perhaps a different supplier for that switch.A great place for Information, Comraderie, and a sucker punch.

        Brian.  Go thru the repair shop regularly to say hello.  Amazing variety, some like anybrand sawzalls you can easily understand.  But I'll tell you what I see almost every time.  Most all the tools in the bins waiting for repair are beat to ####.  Man, bent this/broke that.  Really horrible care given to that equipment.  They do look better going back out the door, but all the missing (don't get in the way) shrouds and other safety apparatus missing is scary.  I'd wear full body armor and a full face shield working with some of this stuff.A great place for Information, Comraderie, and a sucker punch.

          True dat dude.  Some of the crap waiting to get repaired doesn't look like it'd be worth fixing, if you ask me.  Sometimes I wonder if they ran out of space in the bed of the truck and decided to just drag the tools home tied to the bumper.

          When you think about the fact that the tool repair guys legally can't (and don't) return tools without all the safety devices properly repaired I really wonder how cost effective it is to repair some of this stuff.  I'd have to guess that the bigger the company and the larger the number of employees is directly proportional to the floggings a tool takes on a given day.  I guess as an owner, you'd get to the "why bother" point and stop buying or trying to have nice tools.View Image
