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).

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.
