    I have the current Elektra Beckum saw, which has an induction motor.

    While using it yesterday, noticed the brake didn't kick in and the blade span for over 3 minutes until it eventually came to a stop, the brake normally stops the blade within 4 seconds. Also found out today its not working:(

    The saw was purchase second hand around 8 years ago.

    The older Electra Becksum (green model), didn't have the brake feature.

    Anyone have any ideas? Don't want to open it up, last time I tried to repair my Metabo SDS drill, couldn't fit back together again - over engineered :oops:

    I think it is a capacitor that is used as a brake and this may have blown.
    That's what the problem was on my table saw.

    Thanks Chippie, will have a look at tomorrow, don't want to replace the saw as it been very good, a little heavy thought due to the motor.

    Can understand why the older models without the brake were replaced, as you can barely hear the blade spinning.

    I think they stopped making them in about 2008.

    My model was manufactured in 2001.

    At that time they retailed at around £600.

    The model I have is actually the KGS311 ( i think all that is differnt is that it came with all the dust extraction connectors).

    This is essentially a worksthop saw, as it is quite heavy due to the motor, also it can only cut max thickness of about 55mm, due the motor positions

    Metab now make the KGS254, whch is the lates model, the motor is located above the handle.

    It is actually working now, so will wait until the next use as have put it in storage.

    I open up the switch cover today.

    Checked to see if switch was working using tester - OK.

    Checked all the wrings in the terminals blocks and tightened up.

    Checked PCB for any signs of component failure - all looks OK.

    Machine still not working - just the odd occasion start up- without the brake function.

    Then checked the 1.5mm H07 rubber cable flex for continuity, earth OK, live OK. Neutral intermittent. Checked the flex along it's length and found a break just where the rubber clam is to secure the cable. Cut cables twisted and end soldered.

    All sorted now, less a foot of cable flex :)

    Check this out:

    The word 'Jitendra' is actually originated from 'Jitendriya' which means "one who has conquered the senses".

    This is all making sense now, need to live up to my name!

    Ordered some 3x1.5mm HO7RN-F CABLE, cable was to short and had to use an extension lead which gets in the way.

    Purchased these Freud blades for the saw this blade set from SF.

    Really good cut and the saw is much quieter now, blades seem to be whisper quiet.

    If anyone hasn't tried these blades, worth a try ideal for studwork.

    Good make Freud, just usually settle for trend as price tag is less.
