failure
ry 2 to 3 more times after power down
- if it still does not work, please replace the controller and inform the manufacturer.

4 Pedal sensitivity adjustment
Pedal movement starts from the initial position (p.136) where the motor stops, slowly stepped forward to the
low speed point (p.137) where the motor runs at the minimum speed (p.100), proceeding to the accelerated point
(p.138) where the motor start fasten, until the max speed point (p.139) where the motor run up to the maximum
speed (p.101). And when the pedal steps back to the foot lifter position (p.135), the automatic presser foot lifting.
Continuing back to the auto trimming position (p.134), thread trimming is completed automatic. The parameter
value is set for an assurance (No. 134 parameters) < (No. 135 parameter) <( No. 136 parameters) <( No. 137
parameters) <( No. 138 parameters) <( No. 139 parameters). Adjusting the corresponding parameters, user can
acquire the proper pedal response to fit the personal habit.
