Possible Cause
1. Restriction in tubing
2. Tubing was not broken-in
properly before calibrating.
3. DC Pump circuit board is
going bad.
1. Blown Fuse
2. Bad HP Resistor
3. Bad DC Pump Board
1. Seed Treater surge hopper is
not staying full.
2. Restriction in the supply
hopper.
3. Build-up in the atomizing
chamber.
1. Drum is wet
2. The seed treater is set too
level
3. Chains are too loose
1. Overload is tripped
2. Incoming power is incorrect
or has been disconnected.
3. Cord has been cut or is dis-

Solution
1. Flush tubing and check filter
for any restrictions.
2. Allow pump to recirculate for
15 minutes before checking
calibration.

any fluctuations. The pump
board may have to be
replaced.
1. Check fuses
2. Check HP Resistor
3. Change the DC Pump Board

1. Make sure the supply hopper
is staying full. May have to
slow down seed wheel in
order to have a consistant
flow of seed.
2. Check supply hopper for any
debris, and remove.
3. Remove atomizing housing
and clean out any build-up of
material.
1. Dry off any moisture that may
have collected on the outside
of the drum.
2. Adjust the slope of the seed
treater to at least a 3" drop
from front to back. If desired,
more slope can be applied.
3. Check and tighten the drive
chains. Also check the chain
alignment.
1. Hit reset button on Overload
inside control panel
2. Test incoming power.
3. Check cord to motor.
