Scheppach track saw, stopped working, must be an easier way to repair?

It does not belong to me, but I do use it where I volunteer, so when it became unresponsive, I took it home to repair it.

The brushes easy to get to, so meter on brushes, and showed as OK, but brush to plug, open circuit. So next thing to look at was switch.

Having been caught out before with non available spares, first found some details, and it uses a bog standard V3 micro switch, so worth having a look.

But two screws in the handle, one can't get to without dismantling most of the saw, the first problem was to remove circlip from hinge, and then some plate had to be hammered off, it was not easy to dismantle.

Finally got to the two hidden screw heads, and got at the switch, tested it seemed A1, so though field windings, tested seemed OK, so part rebuilt and tested, it worked, not a clue what was wrong, can't really test for a fault once it has gone.

As to why it was built so no access to switch I don't know, I will guess build up of saw dust had stopped the full travel of the trigger, so the cleaning while working on it has cured the problem.

But what a nightmare to work on. Missed out two screws in handle, so next time will be easy.

But are all power tools like this today?

Yes, they are sold cheap and intended to be disposable. Repairs may be possible but don't expect it to be easy.

Only way around that is to go to the likes of Hilti, where tools are leased for a monthly price including any repairs or replacements. Of course the price is vast, and only suitable for those with so much money that they no longer care.

I do not like the track saw, when I came to use it, it took two of us, pushing the track down so the saw could go over the joins, but it has had 5 years of use, and rather heavy use at times.
