FIXING ASSEMBLY

DISPLACEMENT OF SCREW SECURING RECIPROCATING SHAFT BUSHING

This bulletin communicates measures to take in the filed to prevent quality problems caused by
displacement of the screw used to secure the reciprocating shaft bushing.

It was found, different models , that the scre w used to fix t he reciprocating shaft bushi ng in place
becomes loose because of heat or vibration, ultimately falling off the bushing.
In the worst case, the screw falling between the thermal switch and the reciprocating shaft can short­circuit the power line of the fixing heater.
This bulletin contains measures for preventing such a problem as a precautio n for the GP605, which is
deigned based on the same co ncept.

Servicing :

< Factory measure >
Tentative Measures: The screw used to secure the reciprocating shaft bushing is replaced with a

W-sems screw, which tends to remain firmly tightened.
XB1-2400-609 (binding screw) ->XB2-8400-809 (W -sems scr ew)

Permanent Measures: The screw (6mm- lo ng) used to secure the reciprocating shaft bushing is

replaced with an 8mm-long screw. Further, tightening of the nut is added to
the work.

As part of a servicing visit, replace the 6mm-long screw used to secure the reciprocating shaft bushing
with an 8mm-long screw. In addition, tighten the nut.
