7. Pedal stroke 1 for starting thread trimming (U047)
By setting the U068 to the selection 1, can be adjust the stroke until the U069 (1st presser lifting
height).
Setting range : −1000 to −100
⑥ Foot lift function after thread trimming (U055)
This function can automatically lift the presser foot after thread trimming.
0 : OFF Function of automatically lifting the presser foot is not provided.
(Presser foot does not automatically go up after thread trimming.)
1 : ON Function of automatically lifting the presser foot is provided.
(Presser foot automatically goes up after thread trimming.)
⑦ Reverse revolution to lift the needle after thread trimming (U056)
This function is used to make the sewing machine rotate in the reverse direction after thread trimming to
lift the needle bar almost to highest position. Use this function when the needle appears under the press-
er foot and it is likely to make scratches on the sewing products of heavy-weight material or the like.
0 : OFF Function of making the sewing machine rotate in the reverse direction to lift the needle after
thread trimming is not provided.
1 : ON Function of making the sewing machine rotate in the reverse direction to lift the needle after
thread trimming is provided.
(Caution) The needle bar is raised, by rotating the machine in the reverse direction, almost to the
highest dead point. This may result in slip-off of the needle thread. It is therefore necessary
to adjust the length of thread remaining after thread trimming properly.

Manual operation of the presser lifter (U068)
By setting the U068 to the selection 1, it is possible to change the height of the presser lifter in response
to a stroke for stepping the pedal backward.
Default 0
0: Two-step operation
By stepping a pedal backward, the current height becomes changes to the 1st presser lifting
height (U069).
1: Manual operation depending on the amount of a reverse step
The presser foot operates up to the 1st presser lifting height (U069) according to the stroke
for stepping the pedal backward.
⑨ Height of the presser lifter (U069 and U070)
By stepping the pedal backward until the end position of the presser lifter lifting (U047), the presser foot
is positioned at the 1st presser foot lifting height (U069).By stepping the pedal more backward before the
start of sewing and stepping the pedal backward until the start position of thread trimming, the presser
foot is positioned at the 2nd presser foot lifting height (U70).
U69 1st presser foot lifting height Default 5.0 Setting range 0.1 to 8.5
U70 2nd presser foot lifting height Default 8.5 Setting range 8.5 to 13.5
⑩ Reverse feed stitching speed (at start) switching function between Auto and Manual by pedal
directions (U059)
Select whether to perform a reverse feed stitching (at start) at a speed set with a memory switch U008 at
once or perform a reverse feed stitching (at start) at a pedal stepping speed.
0: Manual Manual sewing with the directions to pedal operation
1: Auto Automatic sewing at a setting speed
(Cautions) 1. The maximum of the reverse feed stitching speed (at start) is restricted at the speed
set with a memory switch U008 irrespective of a pedal.
2. At the time of selecting the selection "0," there is a possibility that one reverse stitch
does not come to go with the other reverse stitch.
