Hi all, my little Sentinel has been running great for some time but I have now noticed a few issues.
The wheels seem to have lost their plating, not a great issue but notable all the same.
More worryingly the pickups seem to be adrift, when wheel cleaning for example I find one or two wheels don't pick up solidly, looking at the pickups they don't look to be making good contact with the backs of the wheels.
Is it a big job to lift off the bottom plate, free the wheels and reset the pickups?
Thanks
