4 Pedal sensitivity adjustment    

Pedal starts moving from the initial position ①(p.136) where the motor stops, slowing forward to the 

low speed point② (p.137) 

where the motor run as the minimum speed , continuing to the accelerated point (p.138) where the motor 

start to speed up,  until the max speed point (p.139) where the motor run up to the maximum speed. ②③ keep 

start sewing speed, ③④ is free adjust process. 

1; Pedal starts moving from the initial position ①(p.136), And when the pedal steps back to the foot lifter 

position ⑤(p.135), the presser foot lift. 

2: Pedal starts moving from the initial position ①(p.136),Continuing back to the auto trimming position

⑥ (p.134), the line is cut. 

3. all the parameter should confirm( p.134) <(p.135)<(p.136)<(p.137)<(p.138)<(p.139) 

4. It can be monitored in real time under the monitoring p.025 parameter, and the pedal sampling value 

at different locations is the reference value of each parameter. 

Adjusting the corresponding parameters, the action position of presser foot and front step or back step 

is also changed. If the machine is not running before stepping on a large distance, the 137 parameter can 

be reduced appropriately (Cannot less than parameter 136). It can improve the sensitivity of the front step; 

if the machine is too sensitive, the light touch pedal machine starts to run, and the 137 parameters can 

be increased properly; if it is not easy to fill the needle and step forward slightly, 

The speed increases rapidly to lead multiple needles, which can be properly increased by 138 parameters or 

reduced by 137 parameters (that is to increase the low speed range of the foot pedal), and the initial slit 

speed (100) can be properly reduced.
