Seed Disk Maintenance
When removing seed disks, inspect for wear and
damage. If there is any seed dust or treatment
buildup in the cells (6), or along the raised wiper
ridges (7), clean the disks and reinspect.
Disk replacement is necessary if:
 Chips at the outer edge (8). These chips will leak air.
 Chips at the edges or in surfaces of the cell pockets
(6). These chips can leak air and/or adversely affect
singulation.
 Cracks over 2 inch (5 cm) long in the working face (9)
of the disk, or any cracks in the ridges or grooves on
the face.
 Warping which occurs when any part of the disk does
not press firmly on the seed drop brushes in
operation, replace the disk.
 Wearing along a wiper ridge (7).
 Any wearing on the cells.
 If the air ports (10) have enlarged.
Cleaning and Storing Seed Disks
Possible Chemical Hazard
Seed disks will have talc and graphite residue,
and may have residue of hazardous seed
treatments. Do not wash disks where food is
prepared or where cookware or dinnerware is
washed. Wear gloves when washing disks. Avoid
spray.
Use warm or hot water, mild soap, and a sponge or
soft brush to remove buildup on seed disks.
If disks are washed, allow to dry completely before
storage.
Keep original shipping cartons for disk storage.
Otherwise, store on edge (not leaning), or stacked
horizontally on a spindle, to eliminate any warping
risks.
