Upper Feed Dog Timing
(Part 2)
1.
With the upper feed dial set at "0" the gap
between the two linkages should be 2.5mm.
You could use the blade on the 2.5 mm
tool as a gauge or the smallest step on the
left of the step gauge is 2.7mm, so it
should be a very tight fit inside the gap or
just not fit into the gap.
2. If an adjustment needs to be made, locate
and loosen the hex set screw that holds the
linkage in place with a 2.5mm hex tool.
3. Rotate your screwdriver up and down to
provide more or less gap between the
linkages. Insert the 2.7mm section of the step
gauge. Now, rotate your screwdriver down so it
is very snug against the gauge and tighten the
screw.
