If the switch does not work try the carbon brushes.  I had similar problem with my hand grinder and tablesaw (skil model 3400). I discovered the wire holding the brushes fraid which caused intermitent power geting to the armiture.

What you are describing sounds like the power is being interrupted somewhere. In my experience, this is usually casued by a bad switch. Try replacing the trigger switch.

Table saw motor burning


Sorry, but my advice is to throw it away. With the 5380 anything more than a cord is not worth repairing.
My recommendation is to buy a Makita 5007 series and stay away from Skil.

Skilsaw wormdrive stops working but if I wiggle the cord at the handle it sometime starts and will run until I take my finger off the trigger. Now it won't start at all even after wiggling the co


Replace the cord. Cords get internal breaks by the handle or boot because that's where they have the most bending movement. The wires break inside where you can't see them. When you wiggle the cord the connection is remade, usually with a spark hot enough to hold them together for a short time. When the saw turns off and the cord moves again the weak point breaks again. You can test this by pluggin in the cord and checking for voltage where the cord attaches to the switch.

What capacitor should be on a table saw motor


The part number you reference is a start capacitor. (details can be seen here: http://www.superioressex.com/uploadedFiles/Distribution/North_America/Essex_Brownell/Downloads/Linecards_and_Catalogs/capacitors_w.pdf )

It appears that the component capacitors (there are 2) are not available as separate parts from Delta. They only reference the motor itself (part 220 in the diagrams listed below.)

http://www.ereplacementparts.com/delta-36650-type-table-saw-parts-c-3275_3334_13634.html

At this point, I would try to locate another saw of the same model and read any numbers that may appear on the original capacitors on the motor. Please note the location and connections of each. There should be a run cap and a start cap on the motor.

The differences between a 47uFD and 20uFD caps are not an issue in this application.

Skilsaw is 2 months old. sounds like the bearings are shot already. has an odd klunking sound


even its just a 2 mos.old if your power tool was over used there is the tendency to sound like krunkling sound.,particularly when the unit you bought is just an imitation.
now,if the skilsaw you have now is let me say genuine,not overused and you are not comfortable with the sound you hear from it,then there is the posibility that it has a factory defect.Now,becoz it is already unto you,you can open and check the bearings,and also the "half moon" between the power gear and the axle/rod of the armature,it might be loosen.If your skilsaw is genuine and branded,you can buy it for areplacement of the said bearings & half moon.
you can check the brush too,becoz when it was over used the brushes are surely shortened and not equally grined..and if that so,an uncomfortable sound or noise will hear from it.

The switch is intermittent. The saw has #5375 on the nameplate. I t has the two-handed safety switch where you have to push the red one with one hand and squeeze the trigger with the other hand. Sometimes...


Simply the switch will need replacing and this can be obtained from the mfr or you can get it repaired at a local tool repair center. Get it replaced asap.

Where is blade lock for my Skilsaw 5150 located


look for the button on the right side of the handle. Other models require you to put a phillips head screwdriver into a hole in the blade to hold it against the body of the saw.

Bosch table saw model 4000


It sounds like the pinion on the armature and or gear are stripped. The only way to find out is to tilt the blade and remove the motor housing from the diaphragm and check it. If replacing the armature I would recommend also replacing the bearings and brushes as preventative

Manual for Skil Saw model 77 type 17


I have a Skilsaw model 77 type 16. I have the original owners manual and would be willing to fax you a copy.
The manual only lists a part number for the gear oil, it is No. 249. This is for a 5-3/8 oz tube of gear oil. I checked with my local hardware store which services this saw and they called a factory rep. They told the hardware store with shipping and handling it would cost about $17 for the oil! However they also said that a 90 weight gear oil is close enough to solve the problem.
Hope this helps.
