jteagle77 Posted May 15, 2012 Report Share Posted May 15, 2012 Having problem raising top arm at times. Does anyone have a clue what maybe causing it to do that? Quote Link to comment Share on other sites More sharing options...
Ken O Posted May 15, 2012 Report Share Posted May 15, 2012 Is it stiff or just doesn't stay up? Mine doesn't stay up by itself so I attached a bungee cord up high on the wall to hold it when I release it. Quote Link to comment Share on other sites More sharing options...
jteagle77 Posted May 15, 2012 Author Report Share Posted May 15, 2012 When you release the blade and go to raise the arm up it has catch and won't go up. Mine has never gone up by its self, have always raised it and use a block of wood to hold it up. Quote Link to comment Share on other sites More sharing options...
WolfmoonCT Posted May 15, 2012 Report Share Posted May 15, 2012 Mine does that. I have mine on a foot pedal, and just tap it so that the arm lifts up all the way. Quote Link to comment Share on other sites More sharing options...
bubbaloo158 Posted May 15, 2012 Report Share Posted May 15, 2012 Mine too... although rarely... and I just do as Wolfmoon says. Just give the pedal a quick tap. Bobby Quote Link to comment Share on other sites More sharing options...
jteagle77 Posted May 16, 2012 Author Report Share Posted May 16, 2012 Thanks for all of the advice, so a pretty common thing with the 788. Thought it might be trying to tear up on me only 2 weeks old. Quote Link to comment Share on other sites More sharing options...
wombatie Posted May 16, 2012 Report Share Posted May 16, 2012 Wow, my arm as NEVER gone up. Marg Quote Link to comment Share on other sites More sharing options...
scrollingdesigns Posted May 17, 2012 Report Share Posted May 17, 2012 Have you taken the side cover off the ar and checked to see if it is anything to do with the blade tension wedge or rod? Quote Link to comment Share on other sites More sharing options...
edward Posted May 17, 2012 Report Share Posted May 17, 2012 I have an easy lift and no problem, when I change the blade I give it a little push upward, works fine. edward Quote Link to comment Share on other sites More sharing options...
qlty Posted May 23, 2012 Report Share Posted May 23, 2012 I have a long bunje cord from the arm up to a basement rafter that I adjust the tension of so the arm will just stay up,this works great for me . Quote Link to comment Share on other sites More sharing options...
sullyscroller Posted May 23, 2012 Report Share Posted May 23, 2012 They do make a arm lift for the 788 but i just use a bungie cord and it works great like the others said. sully Quote Link to comment Share on other sites More sharing options...
Moonie Posted May 28, 2012 Report Share Posted May 28, 2012 jimdandy.com has a lift system for the 788. I bought one and it works GREAT ! Quote Link to comment Share on other sites More sharing options...
amazingkevin Posted May 29, 2012 Report Share Posted May 29, 2012 My dewalt 788 has been acting strange.I hold down on the top arm and fasten the blade and when i tighten the tention some times it only goes to 2.4 and other times 5 & 6 on the tenstion knob.i'm sure the blade is straight and all the slack in drawn up before i tighten the blade.Any clues.???

Rubicon Posted June 14, 2012 Report Share Posted June 14, 2012 Mine lifts up and goes down smooth always. It has never had a catch of any kind. I wonder what could be getting in the way. Quote Link to comment Share on other sites More sharing options...
