Important: Keep inside of dryer clean! Do not allow chaff and other
combustible material to accumulate within air plenum chamber. Make
certain to turn off and lock out the main power before entering dryer!

1. Read and understand the operation manual

before attempting to operate the unit.

2. Keep ALL guards, safety decals, and safety

devices in place. Never operate dryer while
guards are removed.

3. Keep visitors, children, and untrained person-

nel away from dryer at all times.

4. Never attempt to operate the dryer by jump-

ing or otherwise bypassing any safety
devices on the unit.

5. Always set the main power supply disconnect

switch to OFF and lock it in the OFF position
using a padlock before performing any ser-
vice or maintenance work on the dryer or the
auxiliary conveyor equipment.

6. Before attempting to remove and reinstall the

propeller, make certain to read recommend-
ed procedure listed in Section 7 - SERVICE.

7. Keep the dryer and wet holding equipment

CLEAN. Do not allow fine material to accu-
mulate.

8. Set pressure regulator to avoid excessive

gas pressure applied to a burner during igni-
tion and when burner is in operation. See
Table 2-1 for operating gas pressures. Do

not exceed maximum recommended drying
temperatures.

9. Do not operate the dryer if any gas leak is

detected. Shut down and repair before fur-
ther operation.

10. Clean grain is safer and easier to dry. Fine

material can be highly combustible, and it
also increases resistance to air flow and
requires removal of extra moisture.

11. Use CAUTION in working around high speed

fans, gas burners, augers, and auxiliary con-
veyors which start automatically.

12. Be certain that capacities of auxiliary convey-

ors are matched to dryer auger capacities.

13. Do not operate in an area where combustible

material will be drawn into the fan.

14. The operating and safety recommendations

in this manual pertain to the common cereal
grains as indicated. When drying any other
grain or products, consult the factory for addi-
tional recommendations.

15. Routinely check for any developing gas

plumbing leaks. Check to ensure that vapor-
izer on LP models does not come into contact
with burner vanes.

War ning! Dr yer Must Be Kept

Clean for Safe Oper ation.
