Track saw guidance?

I bought my ATF55 in the 80's and had the same racing/sudden loss of power. With mine if I turned the speed control to the max possible it would come good, which indicated a dirty pot.

It's a good chance your's is the same, pull the top off the pot and clean nit out, and sand the contacts a little if needed.

I’ll check it out, when I discover which stack it’s hiding in. The Mafell gets used a lot more because the red on the Sys makes it easier to find.

Does a quick shot of DeoxIT clean the pot?

Depends how dirty/carbonised the contacts have become and how much dust has accumulated. On some tools I've also had to bend the wiper arm for better contact to get them working as the springyness had gone over time.

While you have it open a little scrape to expose some fresh metal in part wouldn't hurt.

So your first answer is a good one.

On the 2nd issue of rebending the brush arm to ensure better contact, that seems to be a temporary solution at best as metal fatigue will ultimately prevail.

As much as I enjoy owning "older items" I've learned that the maintenance issues can be extreme...almost to a fault. I want to be a Jay Leno but, I don't have his financial resources.

It actually takes very little to bend it so more pressure/contact is applied if it's warranted. I've never needed to do this more than once on any tool, and some of my tools are ancient! ;-)
