For machines have HP function only.
【 ALT 】mode : Presser foot lifting stroke changed by each time of the HP switch pushed on.
【 MON 】mode : Presser foot lifting stroke must be remained by the HP switch kept on.
M : Magnetic type.
A : Air type.
Note : When set at A type, 【064. FO 】and【065. FC 】setting will be invalid. It will be full on.
64 FO Full-On time setting for foot lifting solenoid 0 - 990 ms 250 Only valid when【063. FTP】set at『 M 』mode. For solenoid pulling torque adjustment.
65 FC Duty cycle time setting for foot lifting solenoid 10 - 90％ 40
Only valid when【063. FTP】set at「M」mode. For solenoid's switching power adjustment.
Note : Wrongly adjustment will cause the solenoid unable to lift or over-heating.
66 FD Running-Delay time setting 0 - 990 ms 80 If foot lifter is installed, set 100 ms min. to ensure the presser foot will come down first.

69 HD Sensitivity adjustment for half-heeling pedal 0 - 990 80
Use this setting as foot lifter delay time at half heeling the pedal. If foot lifter is installed, set 100 ms min.
1.If timing set to short, it will cause foot lifter started once before trimming at full heeling the pedal.
2.If timing set to long, it will cause foot lifter started too slow or laggard at half heeling the pedal.
ON : No foot lifting at half-heeling. (but full-heeling can operate foot lifter )
OFF : Operate foot lifting at half-heeling.
Note : When【134.KLK】= ON for interlock-stitch machine, this function can be controlled by A key on the control box
panel.
ON : No foot lifting at heeling pedal.
OFF : Has foot lifting at heeling pedal.
ON : No function at heeling pedal. ( foot lifter and need up function are also invalid)
OFF : Trimmer is functioned at heeling pedal.
When the pedal is returned to neutral position, trimming works automatically.
O N : Enable. Only valid when【072.FHC】= OFF
OFF：Disable.
