Lubrication & Maintenance
Lubrication
Make sure unit is clean and completely dry. With spreader empty, shut
down spinners and run conveyor at 20 RPM. Lubricate conveyor chain
via display through two full revolutions of conveyor. Lubricate every 10
hours of spreading, or at the end of each day’s use.
Tension
Proper chain tension is a factor in chain and sprocket life. Measuring
from rear of unit, top of chain should appear between MIN and MAX
lines in sight window (Figure 2A), and conveyor should touch bottom
sill
fl
ange at 36” - 40” (762 - 1016mm) mark as shown in Figure 3.
NOZZLE
Figure 1
If manual adjustments need to be
made: With spreader unloaded, run
conveyor at 15 - 20 RPM. On valve
block, loosen conveyor tension
valve jam nut. Turn counterclockwise
to lower tension, or turn clockwise to
increase tension (Figure 2B).

INSERT BIN
WARNING
Keep hands, feet, hair and clothing away from moving parts while system is operating as there
may be danger of entanglement!
Using a 3/4” wrench, turn idler extenders at rear of unit to adjust tension. Turn clockwise to increase
tension, and turn counterclockwise to decrease tension. Measuring from rear of insert bin’s sill, conveyor
chain should touch bottom sill
fl
ange at 30” - 34” (76 - 86cm) mark. Measurements must be equal between
each side.
NOTICE!
Over-tensioning of conveyor chain will lead to excessive load on the system, causing excessive chain
and sprocket wear and can cause extremely high starting pressures. Under-tensioning allows conveyor
chain to “wrap” around drive sprockets and not exit sprocket freely, causing excessive chain stretch
and surging of the conveyor which will result in interrupted
fl
ow of material to the spinners.
