Plugged electric sawzhall in, no power. checked cable -- ok, checked both brushes, still have about 3/8in in each of them. What should I do next? Just replaced the blade, but I do not think that has anything to do with electrical problem.

    K step by step on the power cord is it twist lock and if so can you see where one of the pins has pulled out? Next on the brushes did you notice anything unusul between the 2 of them. How was the saw working up until you replaced the blade? Could be a couple other problems like a flag terminal loosened up at the brush tube to a loose wire at the switch. Let me know and give me the model number and I will get a wiring schematic and breakdown and see what we can do.

I would say its either in your cord(an open wire from wear) or the switch on the sawsall.
Try plugging it in and hold in the switch (dont have a blade in) move the cord around in different places to try to get it to work if thats not it and your brushes are ok its probably the switch. I ve replace bad switches in sawsalls before from wear. You can either go to your local electrical supply store that sells milwaukee and order one or I ve purchase them at Grainger parts too.

My hand held oreck xl has no power it worked yesterday but I plug it in and nothing cleaned it out what else can I do?

The most common problem when a vac is working perfectly and then won't work the next time is a bad plug. You can get a replacement plug at a hardware store and replace it or take it to your local vac shop for repair. The plug that you put into the wall outlet is what I am referring to.

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 :-)

Will not run when trigger pulled .

Obviously, make sure the machine is unplugged before carrying out any electrical work.
You will need to test/check a few things to eliminate possible causes of the problem. Best thing to check first is the brushes. There should be a small screw cover on either side of the back end of the motor. The may be stuck with sawdust so remove the covers and gently pull the brush out. The running face should be nice and shiny where it runs against the commutator/armature. If these are fine, before replacing them, check the wiring inside the plug. Next, check the continuity along the cable from the plug to where it enters the switch. If you only have continuity along one side there is a break in the inner core. This normally occurs near the plug or near the handle where the cable is under most tension. Remove the cable from the plug and pull the faulty core to see if it comes out, if not, do the same at the switch end. If it does come out you can just shorten the cable and hey presto. If there is no continuity and the core is fine at both ends you will have to replace the whole length.
If the cable isn't the problem then test from the switch to the brush holders. One side will go to one holder and the other side to the other holder. If the brushes are back in place you may not get a true reading as they will complete a circuit through the motor.
If this is also ok then you can check the switch by going to opposing terminals and switching it on and off. If in doubt, most switches will have a basic diagram on them showing what terminals switch against each other.

Dc25 animal brush is not spinning,belt is ok,and thers no strainge noises or smells from it.

Hi Kevin,

Thank you for your inquiry. I am sorry to hear about this issue with your DC25 brush bar. Assuming you have already tried cleaning the brush of any obstructions, following the instructions below may resolve the issue:

1) Plug your machine into the power outlet
2) Locate the grey brush bar button next to your power button
3) With the machine turned off, press and hold the brush button down for 10 seconds
4) Release the grey brush button, step on the foot pedal to recline the machine
5) Press the power button to power on the machine
6) Check to see if the brush rotates

If you have any additional questions or require further assistance, please contact our US Dyson Helpline toll-free at 1-(866) 693-9766 or our UK support colleagues at 0800 298 0298. Thank you very much for your time.

No power

Check fuse in plug if fitted, possibly cores in cable have broken, this is most likely to happen at plug and where cable enters body of saw.
You will probably have to open the handle of the saw and do a continuity test with a continuity meter or multimeter from the pins of the plug to where the cores of the cable enter the trigger switch. If this checks out ok, then check brushes haven't worn, check for any overheating on armature.

My trusty PC 7 1/4",15 amp after many years simply stopped running .no electric/burniing smell. hoe do i diagnos burnt out motor versus cord/switch break?

Check the carbon brushes by removing the black cover on the end of the motor. The brushes should be long enough so the spring can hold them firmly against the armature. The end of the brushes should be slightly concave and smooth/shiney. If they are worn down too short or look broken and don't touch the armature replace them. If the brushes are OK, take the right half of the handle off, should be five or six screws. Look for any burn marks or melted wires along the cord and switch wires. Use an electrical multimeter set to AC in the 200V range. Plug the cord in and check for voltage where the cord goes into the switch. If no voltage, replace cord; voltage, move on. If the switch can be locked on do so, otherwise you'll have to have someone hold it on while you check for voltage on the out side of the switch. Again no voltage, replace the switch; voltage move on. If you have power going into and coming out of the switch and the brushes are OK you may have a problem with the armature or field. These have to be tested with a growler to check for shorts. Most electronic shops have one.

Plug in the hammer and no response when you push the trigger

To trouble shoot, easiest to hardest:
1. Check both brushes, they should be 1/4" long or more and evenly worn, the spring should push carbon firmly against armature. If there is a small pin pushing out of the center of the brush it is worn too far and needs to be replaced. The pin is designed to push excessively worn brushes off the armature so as not to damage it. >
2. Check for power at cord going into the switch with a multimeter, if 0V replace the cord, if 110V; push trigger and check for power coming out of the switch, if 0V replace the switch, if 110V >
3. If these are all OK you need to check the armature on a growler to see if it's OK.

We have a Mantis electric cultivator that won't start. it's only a couple of years old

Electric tiller, and it will not run ?
I would check the cord that you plug into.
You must remove the plastic housing, by removing the screws.
Next look at the plug, is it in good shape, has anything been pulled out of it ?
The motor brushes should also be inspected.
Please let us know, we repair all Mantis equipment.
