ADJUSTING THE SPEED CONTROLLER AND AIR PRESSURE   

Speed controller A controls the speed when the 
thread trimming knife holder protrudes. 
Speed controller B controls the speed when the 
thread trimming knife holder retracts. 
If screw A is too loosened, the knife holder will 
protrude too fast and then the position of the knife 
holder will become unstable, causing cutting errors. 
If screw B is too loosened, the knife holder will 
retract too fast and then the looper thread may not 
be held properly (the speed controllers are 
factory-set).

< Note > 

Set the regulator at 4~5kg/cm

. 

To decrease the pressure, turn the adjusting knob 

clockwise.  Excessive pressure will give a shock to 

movable parts and cause damage and trouble. 

< Note > 

Do not connect the relay cord to the motor until the 

stop position of the needle is adjusted. 

Check to see if the thread trimmer knife is fully 

retracted.  Adjust the motor so that the machine 

pulley turns clockwise.
