SETTING THE LOOPER (CONT.)
If more or less looper avoid motion is required, remove cylinder
side cover (A, fig. 8) located at the lower front left side. For plain
feed use a screwdriver to loosen looper avoid link ball joint (B).
For differential feed use Union Special wrench TT85 and loosen
screw stud (C) Moving ball joint down in the lever slot increases
the amount of looper avoid motion, moving it up acts the
reverse. Retighten ball joint (B), or screw stud (C) securely.
NOTE: Whenever looper avoid is changed looper clearance to
needle must also be reset.
SETTING HEIGHT OF NEEDLE BAR
The height of the needle bar is correct when the top of the
needle eye is 1/16" (1.6mm) below the underside of the looper,
with the looper point even with the right side of the needle. To
make adjustment loosen screw (A, Fig. 9) and move needle bar
(B) as required to attain dimension.
NOTE: Care must be taken not to disturb the alignment of the
needles when moving the needle bar either up or down.
SETTING THE FEED DOGS FOR PLAIN FEED
Assemble the main feed dog and throat plate. Main feed dog
(A, Fig. 11) at its highest position, should be set to project above
the throat plate, the depth of its teeth. The feed dog mounting
screw (B) and front support screw (C) should be set to maintain
this setting.
The feed should be set so there is equal clearance between the
front of the feed dog and the front of the feed slot in the throat
plate when the feed dog is at its most forward travel. The same
amount of clearance should be between the back of the feed
dog and the back of the feed slot in the throat plate when the
feed dog is at its most rearward travel. To attain this setting
loosen screws (A and B, Fig. 10) and remove plug screw (D).
Using a screw driver turn eccentric pin (C) clockwise or counter-
clockwise to obtain proper setting. Tighten screws (A and B),
reinstall plug screw (D).
SETTING THE FEED DOGS FOR DIFFERENTIAL FEED
Before assembling the main and differential feed dogs, set the
feed bar eccentric pin (A, Fig. 10A) located in the left side near
center of cylinder, so that the slot in the head is in a horizontal
position for the 35800DLU, DNU, and DZ style machines and
turned counter clockwise to an approximate 45° for the
35800DWW style of machine. The pin can be used to slightly tilt
both feed dogs if necessary. The feed bar pin is retained in
position by set screw (B). Assemble differential feed dog (A, Fig.
11A), main feed dog (B) and throat plate. Both the main and
differential feed dogs can be individually adjusted to height.
Main feed dog (B) at its highest position, should be set to project
above the throat plate, the depth of its teeth. If adjustment is
necessary loosen screw (D) and move feed dog (B) up or down
to attain correct setting. Feed dog support (C) should support
front of feed dog.
NOTE: If eccentric pin (A, Fig. 10A) is used to tilt the feed dogs,
make sure that the looper does not interfere with the rear
needle guard and that the needle guard does not pinch
the needle loops on the back side of the needles.
