Broken needle
• It is extremely dangerous to leave any pieces of
broken needle sticking in the material.
If the needle breaks, search for all pieces until the
whole of the needle is found again.
• Furthermore, we recommend that thorough steps be
taken to account for such needles to comply with
product liability regulations.
NOTE
Oil gauge (1) is not visible
in oil gauge window.
• Is the oil tank empty?
Fill the oil tank with oil.
See Lubrication on page 7.
Sewing machine does not
operate when power is
turned on and treadle is
pressed.
• Is the power supply for the control box
disconnected?
Insert the connectors securely.
See Connecting the cords
on page 9.
• Is the operation panel set to a screen other than a
screen where sewing is possible?
Switch the operation panel to a screen where sewing
is possible, such as the home screen.
Machine does not operate
at high speed.
• Is the sewing speed setting or backtack stitch speed
setting too slow?
Use the sewing speed key to set the high speed.
See Using the operation
panel (Basic operations)
on page 14.
Machine stops during
sewing.
• Has the sewing pattern been set to a fixed stitch
pattern?
In main sewing mode, set the sewing pattern to
something other than "Fixed stitch".
See Using the operation
panel (Basic operations)
on page 14.
• Is the power supply voltage too low?
Check the power supply voltage.
(If the power cord is too long or too many appliances
are being run from a single outlet, this may cause
voltage drops which will in turn cause the reset
function to activate and stop the machine, even if the
power supply itself is normal.)
