Question about Singer 7462 Mechanical Sewing Machine
Remove the top cover (grasp and lift straight up), spray with "Tri-Flow, liberally inside. Pay attention to the right 1/2 and behind the front dials.
In Front, each dial has a small square opening on the side, use the tube included with the "Tri-flow" to squirt lube inside them. DO NOT use WD-40.
Run the machine daily for 5-10 minutes (set the dial "C" [top front that goes up to 8] to 0 also set the dial on top of the case to 0. Move the Zig-Zag lever (upper right) from 0 to 4 and back again. Respray with Tri-flow. After a couple of days, if it is still stuck place a hair-dryer or light nearby to warm it up to skin temp.
Between the temp and the oil, it should begin working.

I just fixed this on my pfaff 230-the problem is the needle position dial-the middle dial with the chrome lever on the right-has froze up .
remove the dial-it doesn't come off by the screwhead in the middle of the dial ,the screw you need to loosen is the one under the wider end of the part of the dial you hold-you will need a glasses screwdriver.
once it is off ,heat the exposed shaft with a heat gun while turning the shaft back and forth with pauses for dripping 3 in 1 oil on the shaft so the heat melts the hardened grease and draws the 3 in1 in to flush out the old grease and lube the shaft.
eventually you will be able to turn the shaft easily-then when it cools off replace the plastic dial.make sure your upper dial is on "0" there is a cam on it that will push down the other end of the chrome lever.
This will work-there is no plastic in the shaft and arm assembly to melt and you don't have to dissasemble from the top-that sucks.
