Lubrication & Maintenance
NOTICE!
The conveyor will move away from the bottom panel if material accumulates under the conveyor or
on the sprockets� The more material that accumulates, the closer the chain will come to the chain
shields� If the conveyor should catch a chain shield, it could permanently damage the conveyor, the
chain shields or the unit� Do not remove material while conveyor or spinner is running!
Lubrication
Make sure unit is clean and completely dry�
Lubricate conveyor chain via display at an interval
of 10 hours of spreading, or at the end of each
day of usage�
Tension
Proper chain tension is a factor in chain and sprocket
life� Measuring from rear of unit, conveyor should
touch at 36” - 40” (91 - 102cm) mark, and top of
chain should appear between MIN and MAX lines
in sight window (Figure 1)� If manual adjustments
need to be made, on valve block, loosen jam nut,
turn counterclockwise to lower tension, or turn
clockwise to increase tension (Figure 2)� All tension
adjustments must be made when machine is
unloaded and conveyor running 15-20 RPM�
NOZZLE

Figure 2B
Over-tensioning of conveyor chain will lead to excessive load on the system which will cause 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 flow of material to the spinners.
