Motor won't shut off unless unplugged

Whenever I plug in the saw, the motor starts up automatically. Is there a short in it or anything? The only way to shut it off is by unplugging the saw.

My Mitre Saw won't start when trigger pulled, seams like a safety is on can't fine it thou.,

most saws have a breaker switch built into the motor.
check on the end of the motor close to where the power cord is attached.
there should be a small button that will pop out if it is popped, usually if the saw is overloaded.
when saw is cooled, push in on button, it will click & stay in when reset.

Have a de walt mitre compound saw 712xe; it has been stored for some time, and does not go when I squeeze the switch.. there is definitely power on the plug.

there is few blocks (physical) which restrain it's movement, but electrical is only and only switch.

check cord to the saw, if power is positively on and no joy, you need
om-meter (resistance) and if you have, continuity meter (i made one from 1.5v battery, 1.5v bulb and about 3m of speaker wire, i done that in 1964 and i am still using it...)

!. unplug power supply
2. rotate blade by hand and check if it rotates freely
3. tap gently on the sides of motor where brushes are
4. remove brushes cover and check they status (sometime bit of dust get there and it is stuck preventing contact)
5. using compressed air - blow all dust from brushes and brushes mounts
6. replace brushes and covers
7. try to start machine again,

if no joy, to exclude cabling and switch:

!. unplug power supply
2. lift the switch cover (of the memory i think it is six screws)
3. check for obvious burns or acrid smell
4. check now for cable to the plug continuity
5. check switch working on both sides
6. replace cover
7. try to start machine again,

if all of these were ok - it will indicate problem with motor, check therefore motor electrical continuity and flows

i hope you will find this little instruction helpful, do not forget to vote :-)

Make sure pump is submerged i water
Remove tubing from pump discharge and see if pump is pumping water/ If so your tubing is clogged between pump and saw. Remove tubing and rinse out with hose.

Circular saw won't start after having cut pavers

You fried the motor and most of the time it isn't worth repairing, since the parts will cost you more that a replacement saw.

If you are going to continue to cut pavers, suggest you either take it very slow and cut 1 or .5 paver and then let it cool down. But a water cooled tile saw would be better.

Craftsman 10 in miter saw just stopped working...not getting any power. Any ideas?

Check the brush under the black caps on the side of the motor. Make sure the plug is unplugged while you are checking it out.

How do you change the blade on a GMC 10 inch cmpund miter saw?

With the saw unplugged, push the spindle lock in on the motor side of the saw (a short black rod) while turning the blade by hand. The spindle lock will seat and hold the blade still so that you can use a wrench to loosen the nut that holds the blade on. Use the spindle lock again for tightening a new blade on the saw.

Ryobi circular saw --it keeps tripping my breaker

Possible bad circuit breaker. If on a ground fault sensing circuit, the saw may have electrical leakage from it's internal wiring/motor to case ground (a possible problem if you have been using a metal cutting blade)(test by using a 3-pin to 2-pin adapter [no ground pin]). The circuit breaker may not be rated for the starting load of the saw (check the saw load rating against the breaker current rating--the breaker rating should be at least 25% higher). Possible excess current draw in the saw if any of the motor windings have shorted together for whatever reason. Hope this helps!

Manual for #103.0205 circ. saw

Earlier comment 103.0205 Table Saws does not need lubrication is simply wrong.

The103.0202, 103.0203, 103.0305 Craftsman Companion Table Saws main Arbor axle DOES have to lubricated or else the axle bearing will quickly loosen side-to-side or vertically and fail to provide accurate saw cuts.

FWIW, Sears no longer sells Arbor Axle replacement parts... The Table Saw Arbor axle and Bearing Housing cannot use sealed bearings unless the saw case is re-milled and extensively modified. There are 2 Oil Hole Plugs (part# 475-32) that need to be opened and oil applied so the Arbor axle shaft does not get scored or worn.

I use 30wt motor oil to relube the Arbor Axle Shaft depending on amount of use, temperature, and axle rotation stiffness.

Remember, the higher the RPM speed of the table saw motor and/or the longer the use, the more frequently you may need to relube the Arbor Axle Bearing!

Radial saw motor just buzzes.

It sounds like the start circuit is shot on the motor of the radial saw. It is trying to start, (the buzzing sound), but the start is not is burnt out, and therefore the run winding is drawing excessive amperage trying to start the motor (a job it is not designed to do) and eventually builds a amp draw in excess of the circuit. You will have to determine which is cheaper a new motor, or a new saw.

Hope this helps

Sears 10 inch Radial Saw wont run

Try blowing out the motor with compressed air, while rotating the blade by hand. (unplug it first.) Then press really hard on the reset, as sometimes they won't move much at all but will have popped. Use a center punch gently if you have to to push on it. If that doesn't yield results, I'd try spinning the blade by hand a bit and then pulling the start switch to turn the motor on. I once got one to crank up again by doing this, and it continued to work afterwards. (Be careful!) Seems like they are like old starters sometimes that get dead spots in the windings....
I know those are pretty basic ideas, but I have one I've managed to keep running for years as well, and would hate the thought of having to replace it... Also seems to me once I had to remove the cover from the motor and repair a shorted wire inside that was touching metal somehow. And that was only apparent after a similar jam of some sort, as I recall...
Best of luck and encouragement, anyway!
