Lubrication Procedures
If the motor is equipped with an alemite fitting, clean the tip of the fitting and apply 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 having drain plugs, remove drain plug 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 2" to 3" length of grease string into each hole on motors in NEMA 215 frame and smaller. Insert 3" to 5" length on larger motors. On motors having grease drain plugs, remove plug and operate motor for 20 minutes before replacing drain plug.

Additional Checks
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.If required, inspect ignitor plug and clean the electrodes. Use an ignition point file to remove carbon and rust between the electrode surfaces. Ignitor gap should be about 1/8''.
3.Inspect flame sensor for possible damage or poor connections. Flame sensor wire must be in good condition.
4.Inspect and manually rotate the top auger paddle assembly. The paddle unit must rotate freely without any indication of sticking or binding.
5.Inspect the top auger and bottom auger drive lines for proper adjustment and condition. Readjust line tension as required.
