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.
