Header Lubrication & Maintenance
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” (91 -
102cm) mark as shown in Figure 3.
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).
Figure 2A Figure 2B
Insert Bin
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 as shown in Figure 3. 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 excessive chain
stretch and surging of the conveyor which will result in interrupted fl ow of material to the spinners.
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.
Only lubricate insert bin conveyor chain strands annually with Fluid
Film™ or equivalent.
NOTICE!
Do not allow lubricants to contact belting as they will cause
the belt to deteriorate and fail prematurely.
