Went to clean a piece and the flexshaft handle got incredibly hot very
fast and stayed that way.
G’day; I suggest you remove the handpiece from the shaft, and the flex
shaft from the outer flex tube, and soak the lot in kerosene and wash it
well; use an old paint brush. Dry it all out as best you can with tissues
of rags, allow it to drain thoroughly - overnight preferably - then
relubricate the lot with fresh low viscosity MINERAL oil. (Vegetable oils
oxidise and goo up - and I have me doubts about three-in-one too!) She’ll
run like a box of fluffy birds! And cheers!
