2. Front handle with stiffener Front handles will be reinforced with a stiffener
(arrow) in future. The present IS-P6 x 19 spline
socket head screws will be replaced by the longer
IS-P6 x 21.5 screws due to the extra thickness.
To ensure trouble-free replacement, the longer
screws will be supplied with the replacement front
handles.
2.1 Which replacement front handle is needed
A for machines with heated handles?
There are two replacement front handles for
machines with heated handles. The only difference
between them is the resistance of the heating
element.
B The correct replacement front handle can be
identified on the basis of the heating element in the
rear handle or by measuring the resistance. The
145TI038 KN
resistances in the following table are measured at a
temperature of 25°C (77°F).
A: Front handle without stiffener
B: Front handle with stiffener

Most of these PDFs embed fonts with a shifted character map, so the text above was recovered rather than copied — read it as a faithful but imperfect transcription, and treat the page image above each block as the authority where the two disagree — the figures exist only there, because they are vector drawings that text extraction cannot keep.
