4.Trouble Shooting
Phenomena
Possible cause
Remedy
④Foot groove not match
the needle
⑤Thread not through in
the correct way
⑥Needle not properly
fixed
Adjust the foot groove to match needle
Through in the correct way
Make sure needle groove point to the operator
Poor thread
tightening
①Differential ratio too
small
②The bottom of foot is not
paralleled to the feed dog
③The pressure of foot is
too heavy or too light
Increase differential ratio till the material flat
Parallel them
Adjust the pressure
1locked
respectively of
the layer
①Pressure of the foot too
much or not flat
Increase the pressure
②Resistance of foot too
much or not flat
Polish the foot or make it flat
③Feet dogs are not
parallel
②Knife blunt
Change the height of feet dog to make them parallel
Make knife sharp or replaced
Stitch is not
equably
①Thread through in wrong
way
②Thread bracket fixed in
wrong way
Make the thread through in the correct way
Adjust the thread bracket make thread pass easily
③Knife bottom fixed in the
wrong way
④Trimmer edge out of
order
Adjust the knife bottom
Skive lower knife or change upper knife
Noise
⑤Hole for thread broken
⑥Needle point broken
⑦Feeding device not in
the right height
①Parts loosen and collide
with each other
Polish the hole edge
Change to a new one
Adjust the height
Check the machine comprehensively then tighten all the loosen
parts
③Needle bracket is not
fixed in the right place
Adjust the needle bracket make thread 0.1mm away from needle
guide
④Knife can't cut
immediately
⑤Needle too big
Make it sharp or change a new one
Make needle match material
②Lubrication system
blocked
Clear the pump make oil get through fluently
⑥Width of locked part
less than needle plate
Change the width or replace the needle plate
Trimmer edge
not orderly
①Knife fixed wrong
Make the knife in the right position
⑧Pressure of foot too
heavy or light
Adjust the pressure
③Rubber mat out of palce
Make sure the mat put in the right place without noise uttered
①Oil prevent plate of feed
dog
Replace the broken part and tight the screw
Oil leak
