ADJUStING the foot PreSSer
• Enough pressure must be used to hold the work firmly in the
needle plate. light work will not require as much pressure as
heavy work. Too much pressure will cause the presser-foot
to mark you material. If the pressure is too light, the work will
move and irregular stitching or a broken needle may result.
• To apply more pressure on the foot, open the nut (UL-15) on
the top of the spring (UL-101) and turn the spring adjusting
screw (Ul-103) clockwise for more spring pressure on the
foot.
• When you have enough spring pressure on the foot, tighten
the nut on top of the spring.
ADJUStING the foot LIft
• The foot should lift just high enough to clear the work.
If the foot doesn't lift high enough, the work not move
effectively causing smaller stitches or the awl will cut the
leather.
• Turn the balance wheel, until the foot lift adjusting arm
Ul-116 (on the top left of the machine, if the operator is
sitting in front), is turned with the 2 screws facing to the left
of the machine.
• To make the foot lift higher, loosen the inside screw UL-
117 and tighten the outside screw.
• If the foot is lifting to high, loosen the outside screw and
tighten the inside screw.
• NOTE: Never put oil in the foot lift area, parts UL-120 to
UL-127. Oiling in this area will prevent the mechanism
from lifting.
