Changing The Feed Rolls - Kemppi Kempact 251R Operating Manual

Changing the feed rolls

Kempact RA machines are factory fitted with wire feed rolls as part of the delivery packages.
However, it may be necessary to select alternative feed rolls to suit different filler wire sizes
used. So you may occasionally need to replace the feed rolls. Kemppi feed rolls and gun liners
are colour-coded in order to make identification easy.
