WARNING :
To prevent electric shock or personal injury caused by abrupt start of the sewing machine, turn
OFF the power and remove the cover after an elapse of 5 minutes or more. To prevent personal
injury, be sure to turn OFF the power and replace the fuse with one with same capacity after remov-
ing the cause of blown-out of the fuse when the fuse has blown out.
(13) Replacing the fuse
1) Turn OFF the power with the power switch after
confirming that the sewing machine has stopped.
2) Draw the power cord from the power receptacle
after confirming that the power switch is turned
OFF. Then wait for more than 5 minutes.
3) Remove six screws fixing the rear cover of the
control box. Then slowly open the rear cover.
4) Grasp the glass section of the fuse to be replaced
and remove it.
5) Use the fuse with the specified capacity.
The machine uses the
following four fuses.
and
For servo-motor power protection
15 A each
(Standard melting fuse pcb direct-installing
type)
For control power and active tension
protection
10 A (Time-lag fuse)
For stepping motor protection
6.3 A (Time-lag fuse)
(14) Standard of replacing time of the gas spring
1) Gas spring is one of the consumables. Gas inside
the gas spring will be gone naturally even when
the frequency of use is low and the spring cannot
display the thrust to secure the safety.
In case a force of 156N or more is necessary when
passing strings through the front end of machine
bed and lifting the sewing machine as shown in
the left-hand figure, quickly replace the spring with
JUKI genuine gas spring (Part No. : 40061247).
Gas spring is a component that can be used
with ease. However, there is a flaw on the rod
section or a section that is weak in the side
load when the gas spring is fully stretched.
Be very careful when performing maintenance
or cleaning of the sewing machine.
DANGER :
There is a risk of pinching of hand, fingers and arms to cause a serious injury if you raise it when
the gas spring does not function, since the sewing machine is very heavy in weight.
In order to prevent an accident, be sure to replace the gas spring with a new one before it is too
late according to the standard of replacing time (as described below).
