2) Shift the 2nd pin to the left.
3) Bring the feed driving eccentric cam into contact with
the positioning cam.
4) Tighten two setscrews of the feed driving eccentric
cam.
5) To return the timing to the standard adjustment, return
the 2nd pin to its home position. Assemble the feed
driving eccentric cam and the 2nd pin so that they
come in contact with each other. (To obtain the timing
of the standard adjustment, the 2nd pin should be
positioned at the rightmost end of the hole.)
* To prevent the setscrews from loosening, make sure
that the positioning cam comes in contact with the
feed driving eccentric cam.
Note that, however, the 2nd pin can move to the
right or left. It is therefore necessary to make sure
that a clearance is provided between feed driving
eccentric cam and positioning cam before checking
the timing.
16. Adjusting the feed locus
The timing of feed driving eccentric cam of the feed
mechanism can be retarded from the timing obtained
by the standard adjustment.
1) Loosen two setscrews of the feed driving eccentric
cam.
Carry out the adjustment when the hole in the feed
driving rod aligns with the screw of the feed driving
eccentric cam.
