6. STANDARD OF REPLACING TIME OF THE GAS SPRING
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 130N 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. : 40023177).
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 clean-
ing of the sewing machine.
CAUTION
:
• Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.
• When tilting/raising the machine, be careful not to allow your hands, fingers or any other part of
your body to be caught in the related parts.
