SAFETY PRECAUTIONS

1.Read and understand the operating manual before trying to operate the dryer.

2.Never operate the dryer while the guards are removed.

3.Power supply should be OFF for service of electrical components. Use CAUTION in checking voltage or other procedures requiring power to be ON.

4.Check for gas leaks at all gas pipe connections. If any leaks are detected, do not operate dryer. Shut down and repair before fur- ther operation.

5.Never attempt to operate the dryer by jumping or otherwise bypassing any safety devices on the unit.

6.Set pressure regulator to avoid excessive gas pressure applied to burner during ignition and when burner is in operation. See chart for operat- ing procedures. Do not exceed maximum recommended drying tem- perature.

7.Keep the dryer clean. Do not allow fine material to accumulate in the ple- num chamber. Also occasionally clean the outside screens of the dryer.

8.Keep auger drive belts tight enough to prevent slippage.

9.Use CAUTION in working around high speed fans, gas burners, augers and auxiliary conveyors which START AUTOMATICALLY.

10.Do not operate in any area where combustible material will be drawn into the fan.

11.Before attempting to remove and reinstall any propeller, make certain to read the recommended procedure listed within the servicing section of the manual.

12.Be certain that capacities of auxiliary conveyors are matched to dryer auger capacities.

13.Clean grain is easier to dry. Fine material increases resistance to airflow and requires removal of extra moisture.

READ THESE INSTRUCTIONS

BEFORE OPERATION AND SERVICE

SAVE FOR FUTURE REFERENCE

USE CAUTION

IN THE OPERATION OF THIS EQUIPMENT

The design and manufacture of this dryer is directed toward operator safety. However, the very nature of a grain dryer having a gas burner, high voltage electrical equipment and high speed rotating parts, does present a hazard to personnel which can not be completely safeguarded against, without interfering with effi- cient operation and reasonable ac- cess to components.

Use extreme caution in working around high speed fans, gas fired heaters, augers and auxiliary con- veyors, which may start without warning when the dryer is operating on automatic control.

KEEP THE DRYER CLEAN

DO NOT ALLOW FINE

MATERIAL TO ACCUMULATE IN THE PLENUM CHAMBER OR SURROUNDING THE OUTSIDE OF THE DRYER

Continued safe, dependable opera- tion of automatic equipment de- pends, to a great degree, upon the owner. For a safe and dependable drying system, follow the recom- mendations within this manual, and make it a practice to regularly in- spect the operation of the unit for any developing problems or unsafe con- ditions.

Take special note of the safety precautions listed above before at- tempting to operate the dryer.
