    Default Saw won't cut

    So I bought 2nd hand a Dewalt DWE560-XE circular saw, bought as a "runner and yes I tested it before purchase and spooled up and cut off as it should.

    So get it home and have an electrician mate cut off the 6 taped up joins in the power line and it runs well until you put it under load then the blade just stops, to motor is still running but the blade isn't

    Its been in the too hard cupboard for 13 months or so. Does anyone have any thoughts or it a bin job.

    Thanks

    Scott

    Do you mean the blade is spinning on the shaft? If so I would be checking that the blade clamping washers are actually clamping on the blade; if it is a thin kerf blade it’s possible that it’s too thin. Another possibility is if the blade has a reducing bush fitted then make sure it isn’t made from thicker material than the blade itself.

    I'm also pretty sure the inner flange is reversible, depending on what dia arbor hole the chosen blade has.

    If the wrong way around, the blade may be 'pinched' and the bolt feel tight when fitting, only for the blade to drop into place (and consequently be too loose) under first load.
    I may be weird, but I'm saving up to become eccentric.

    If none of the above suggestions work, then first check the carbon brushes to see if they are worn out and need replacing.
    If they are OK then run the motor and watch to see how much sparking the carbon brushes are doing.
    If there is a lot of sparking, then it is likely one or more of the rotor windings are burnt out = sorry, put in electronic waste recycling collection.

    I don't know if this picture is just a generic photo or if these saws have a gear drive. If it does then that might be your problem, stripped gears. You should be able to rotate the blade slowly by hand and you will feel the teeth jump if it is a gear drive and it has damaged teeth otherwise it will have smooth rotation (ensure it is unplugged when you do this!!).
    If not then it sounds like the blade is not being clamped properly when the bolt is tightened and you will need to determine why.
