and fix it with the set screw
At that time, the needle thread clamp sensor cord
should be passed beneath the lubrication pipe
and
the oil drain pipe
.
If the needle thread clamp sensor cord
is located above them, this can be a cause of abrasion or cable
breakage in the crosswise feed main
.
4. Using the harness band
and the lubrication pipe holder
, stretch and fix the lubrication pipe
along
the wall side of the frame.
At that time, make sure not to permit the lubrication pipe
to touch the needle thread clamp connector link.
5. Bundle the needle thread clamp sensor cord
, the lubrication pipe
, and the oil drain pipe
