Suggested Questions And Answer :


I have a delta contractors table saw that wont start. It has a Marathon Electric Motor 62-044 that hangs off the back. It has capacitors rather than brushes. When you turn on the swithch it does nothing. I checked the power to the saw an its good. I think it may be the capacitor(one or both). When you turn on the switch it does nothing no buzzing nothing. Is it the capacitors and do I have to split the motor(pull out the long bolts that run all the way thru the motor to get at the base of these capiaitor wires or not. Ideas????


Most likely to quit suddenly is the switch.My table saw switch broke recently, and at first I thought it was the motor.Over the years I remember seeing table saws fitted with a handy box and ordinary light switch to replace the table saw switch.Check for power at motor: Sometimes the wire connection from switch has access box on the motor where you can get in and check for power.

Stihl ts400 runs rich and wont idle


Sounds like it is leaking on the inlet needle, a pressure test of the carb will quickly tell you this, the needle will have a rubber tip, if dust has gone through the carb the needle seat may be worn, the needle is replacable unfortunatly the seat is not, the metering lever is also adjustable, if it is set too high the needle will leak, it is also important that on the metring side the gasket goes on first followed by the diaphram, the gasket acts as a spacer, the metering lever should be level with the sides of the carb body, if too high simply bend it down, if the metring lever is high this is a good sign the rubber tip of the needle is worn.

Dewalt Model D304-04 reciprocating saw wont run. I plug it in, pull the trigger and it wont start. What am I doing wrong or what could the cause be?


Hi Fred: Hmmmmm. - Confirm there is power in the plug. - use continuity meter to check that there is a complete circuit through the saw. - broken connection in plug? - broken wire between plug and switch? - switch not functioning? - switch set between forward and reverse? - Speed control potentiometer contacts dirty? - Bad brushes?

I have a Craftsman table saw a few weeks back had problems getting the saw to run....would have to hit the switch several times to make it run. Once it was running it was good until I shut it down, then I would have to hit the switch 5 or so times to get it to run again. Today it did the same thing and now just wont run. The blade turns freely by hand and is not binded or anything. Does this sound like a bearing? Brushes?


Replace the switch? Hello!

My tablesaw wont speed up and run. Bosch 4000 ten inch. It makes a klunk and starts to turn and slowly speeds up until its running, but still makes a knocking sound


Is it spinning the blade at all? If it is then it is unlikely to be an electrical fault. Have you considered a motor bearing fault? If the motor bearings are worn, it could turn freely by hand, but when powered up it would stutter and stall. The motor is basically a big electro-magnet so if the armature has enough lateral movement, when it is magnetized it could rub against the stator. If the machine is buzzing, but not spinning the blade it is more than likely going to be caused by a faulty capacitor as this is the component that gives the motor the initial 'kick' in the right direction to get it spinning.

Makita circular saw wont run properly


Something more sinister. I think the armature is bad. (The center part of the motor that spins) Look at the brass bars on the comutator...where the brushes ride....there should be a nice even dark stripe the width of the brush all the way around. If one or two bars a discolored beyond that it's not good. Or if there is heavy pitting in between bars it's also not good. And lastly the more obvious sign is bars missing from the comm..

My Brand new Stihl ts420 cut saw wont run full throtle, smokes white, and leaks fuel out of exhaust filter. it runs like the choke is half on.


This sounds like the carb is flooding, there is a rubber tipped needle under the metering side of the carb, this may be leaking, before replacing the needle make sure the air filter is not blocked, replace with a new filter and try again
