When tighten the rollers, steady
the roller bolts with the sup-
plied screwdriver to prevent the
roller shafts from being twisted
off.
- Push the filament guide upward far
enough to ensure that the rollers do
not rub against the filament guide
and that the process material can slide
unhindered into the roller grooves
(fig. 5.2k center line).
