Note: All of the auger and me- tering roll bearings are lifetime lu- bricated and do not require service relubrication.
1.Remove and clean the gas line strainers. Make certain gas valves are closed and that gas is purged from the system before attempting disassembly.
2.Inspect the collector plate at the top of the burner casting and the burner cup for any accumu- lation of foreign material. Clean if required. Foreign material in the burner cup or casting will not burn out and will impair burner operation.
3.If required, inspect ignitor plug and clean the electrodes. Use an igni- tion point file to remove carbon and rust between the electrode sur- faces. Ignitor gap should be about 1/8 inch.
4.Inspect flame sensors for pos- sible damage or poor connec- tions. Flame sensor wires must be in good condition.
5.Inspect and manually rotate the top augerpaddleassembly.Thepaddle unit must rotate freely without any indication of sticking or binding.
6.Inspect the top auger and bottom auger drive lines for proper adjust- ment and condition. Readjust line tension as required.
Note: All of the auger and me- tering roll bearings are lifetime lu- bricated and do not require service relubrication.
7.Operate dryer clean out levers, and check cleanout hatch mecha- nism for proper operation. With hatch open, inspect and remove any accumulation of dirt, fines and foreign material from the bottom auger trough area.
Note: Do not allow high mois- ture material to collect within the trough area. It may adversely affect metal parts.
8.Inspect entire dryer for loose, worn or damaged parts. Include check of auger flighting, metering rolls and other internalparts. Check that tem- perature sensors within air ple- num chamber are secured within insulated clamps, and do not chafe on other metal parts.
9.Make sure all dryer guards and warning decals are securely in- stalled. Make certain guards do not interferewithmovingparts.Ifguards or warning decals are missing, con- tact your dealer for a free replace- ment.
10.Test fire the dryer several weeks ahead of the drying season. Check for possible gas leaks. See page 16 for burner test fire.
