12. Inspect the entire dryer for loose, worn or damaged parts. Include check of auger flighting, metering
rolls and other internal parts. Check that temperature sensors within the air plenum chamber are
secured within insulated clamps and do not chafe on other metal parts.
13. Make sure all dryer guards and warning decals are securely installed. Ensure that guards do not
interfere with moving parts. If guards or warning decals are missing, contact your dealer for a
free replacement.
14. Test fire the dryer several weeks ahead of the drying season. Check for possible gas leaks.
(See Page 18.)
NOTE: If on site bearing lubrication is to be performed, see lubrication instructions for ball bearing
motors. To keep motor bearings properly lubricated and dispel any accumulation of moisture
within the windings, the fan and auger motors should be operated for 15 to 30 minutes
each month.
Lubrication Procedure
If the motors are equipped with an Alemite fitting, clean the tip of the fitting and grease with a grease gun.
Use 1 or 2 full strokes on motors in NEMA 215 frame and smaller. Use 2 to 3 strokes on NEMA 254 through
NEMA 365 frame. Use 3 to 4 strokes on NEMA 404 frames and larger. On motors with drain plugs, remove
drain plugs and operate motor for 20 minutes before replacing drain plug. On motors equipped with slotted
head grease screw, remove screw and apply grease tube to hole. Insert 5 to 8 cm length of grease string
into each hole on motors in NEMA 215 frame and smaller. Insert 8 to 13 cm length on larger motors. On
motors with grease drain plugs, remove plug and operate motor for 20 minutes before replacing drain plug.
NOTE:
All of the auger and metering roll bearings are lifetime lubricated and do not require service lubrication.
