Need Advice DeWalt 735 Planer GO then NOGO issues

[charlessenf]

The thing just sits there most of the time. Months go by w/o a need to plane a thing. Then I have to plane a few boards and all is well. Then, not too many days (or 24 hours) later, I come back and it will not start.

First time this happened I thought I might have switch speeds while it was off, so I too it apart and found the gears involved but could not determine such was the case. And, yes, I checked the power first and all was 120VAC. I bolted it back together and it started.

The next time it didn't start up, I took it apart and tried rotating the pulley/belt/motor, pt it back together and it started. Once it started 9each time) I was able to complete the intended planing.

But, the next time I went to start it, it would not.

This machine has a nice wooden stand on rollers and rests most of the time in a quiet corner of the shop - no AC , but a propane forced air heater in the dead of Winter as needed (less so as I age). So the life of Riley. A little sawdusty maybe, but nothing to sneeze at.

Has anyone else experienced this sort of thing?

It must be eight years old or more. I think I posted a gloat about how I got the extension tables free way back when - and one or two of the corporate members got on me about that then.

Sounds like you need to replace the reset button. You can buy the part and watch how to videos on line, or drive it down to the repair facility in charlotte

Possibly the on/off switch? I had an old Craftsman table saw that acted up for a while and then quit altogether.

The switch had fine sawdust in it that eventually would not let it make contact.

Tore the switch apart, cleaned it, and used the saw for another year or so before giving it away when I got the Unisaw

The reset function on these players is the weakest link. They have a limited life of about 25 resets

Thank you all for the feedback

1. replace the reset button
2. switch had fine sawdust in it
3. The reset function

So far, the 'fix' has been "rotating the pulley/belt/motor, put it back together and it started"

I'm cannot recall the location of a reset button. Could be A.G.E. disease, but likely 'cause I've not used it? Seems as if either the switch or the reset button (mechanical devices; switches, actually), would either work or not. Why rotating the motor has a salutatory effect seems 'the clue.'

I have yet to try it again as taking the cover off is a four-bolt PITA

I will find the reset switch and examine it and the power switch nonetheless and report.

Thanks again

Reset on mine is to the immediate right of the power switch

If rotating helps, take the brush caps off and ensure that you don’t have a sticky brush.

Only had mine about a yr, will keep switch & reset in mind for future if it gets hinkie. So far no need to reset.

FWIW, I got the tables and extra blades essentially free in a roundabout way - a price match plus a $50 Lowe’s gift card I had won from AARP.

Charles, if you bought the unit used, you unfortunately have no idea how many times the reset button has been used. But, if you get on line and google it, you will find plenty of posts confirming that this part of the device is the weak link and it needs to be replaced after ~30 resets. It is usually triggered by taking too heavy a cut on too wide a board. I doubt it is the power switch. Dewalt's service depot in Charlotte is top notch if you dont wish to replace that part.

"if you bought the unit used"

Nope, bought it brand new sealed box from LOWES!

No, the reset button theory bothers me because, if I've never pressed it, yet the machine recovers when I rotate the belt a bit, how does my (belt moving) action impact a reset switch?

I know how they work - got one on my Craftsman TS. Push a piece of hard wood too aggressively and the motor cuts out. Wait seven minute, press the red reset button and all is well again.

Please don't get me wrong, I appreciate the applicable experiences of others. I'm just not sure I've conveyed my experience sufficiently.

Is there anything online about TESTING the reset switch? By passing it?

FYI: There is also a switch activated when the cover is removed. It is easily by-passed with a stick. I've tested it and it seems to work fine.

If it starts after rotating the motor, it sounds like a bad spot in the armature. I've seen that happen many times on engine starters.
Or sticking brush as Mike stated.

 

[charlessenf]

take the brush caps off

Are they readily accessible? I've never looked for them to date.
Is there a place (link) where I could get an exploded diagram and parts listing?
Replacing the brushes on some motors is really simple - might do it 'just in case/can't hurt.'

What worried me was the WARNING not to change speeds unless the tool was on and turning. I figure there must be some mechanical thing that could impact the operation and - maybe I moved that speed lever once when I shouldn't a done it.

No idea where the owner's manual got to. I put it away where it belongs - sure of that. Just not sure of where I was certain it belonged ten years ago.

DW735 brush replacement...

 

[ChemE75]

Not sure on ease of access to brushes, but agree @Pop-pop’s suggestion to check brushes, worth a look. But then I believe a flaw that might be simply due to age, vibration, etc in the reset switch could interrupt power to the motor, so I’d try to check that out as well.

A while back I found brushes for my ‘60s p-c router on Amazon - just in case.

A while back I found brushes for my ‘60s p-c router on Amazon - just in case.

Right found a pair on Amazon and they are 'on the way.' Figure to replace them and see if that does it. Replacing the armature or entire motor is ten times and twenty times the cost and the labor - hope the brushes do it!

Did you determine it was the brushes? I would take a leaf blower to mine, open up whatever covers i could and blow it out first.

"I would take a leaf blower to mine, open up whatever covers i could and blow it out first."

OK, but how's that fix my planer?

OK, I can try that, too. Before I replace the brushes Amazon's sending me (tomorrow?)

If, after the blowing out the planer, it starts, I can always return the new brushes.

Arrived at four, installed and tested by 4:30
Note the PRC Label - for a 735 TableSaw!

Right, I used a compressor and a shop vac to blow it off and suck the dust out.. Used a shorty Screwdriver inside (after removing the one tall bolt that held the cover on. Hindsight: After looking at the old brushes, next time I'd just pull them out of the back and put that one inside and do the same with the one from the inside - bet a buck it would have worked!
