6. Maintenance
Turn off the power switch before performing check
and adjustment work.
Eject all working screws from within the feeder before
proceeding with maintenance work.
A dirty rail groove could slow down the working screw transfer speed. If
the rail groove is found noticeably soiled, wipe it off with a thin cloth
impregnated with alcohol.
If the rail groove is difficult to clean, the rail can be detached from the
feeder for cleaning. Before detaching the rail from the feeder, turn off the
power switch and remove the screws from the scooping chamber (to
prevent screws from falling out).
Remove two front cover mounting screws and move the front cover.
Remove the cutting disc assembly mounting screw and then detach the
cutting disc.
(See 7.3, “Replacing the Cutting Disc Assembly.”
Then, loosen the rail longitudinal position setscrew and pull out the rail
assembly to front.
The rail should require replacement if its rail groove is soiled or flawed to
impair its successful use.
If the rail assembly has been removed from the feeder, it is necessary to
make positional adjustments with the tip of the rail and the cutting disc.
• Align the groove rail and the groove in the cutting disc with each other.
• Mount the cutting disc assembly to keep the top surface of the groove
in the cutting disc lower than the top surface of the rail groove.
• Turn on the feeder and then make adjustments with the longitudinal
position of the rail so its tip will not hit the cutting disc when the rail
vibrates.
