Note :
When applying or removing the finger attachment to the finger, hold the finger attachment
with a tool such as a wrench to support it to tighten the attachment screws to avoid load or
stress applied to the guide part.
The heat of the unit is conducted from the fingers to the work part via the finger attachments.
To block heat from being conducted to the work part, use a material with low heat
conductivity such as polyacetal for the finger attachment.
(Reference)
When operated with duty 50%, the temperature rises in approximately 40C at the unit
attachment surface (side surface) and finger attachment surfaces.
[Refer to 6.4 Temperature Rises on Main Body and Finger]
