SEASONAL INSPECTION AND SERVICE

The dryer is made of weather resis- tant material, and is designed to re- quire a minimum of service. However, each season we recommend the fol- lowing items be checked before the unit is used, and any damaged or questionable parts replaced. These checks will help eliminate possible failures, and assure dependable op- eration of the equipment.

1.SHUTOFF electrical power. OPEN power box and control box, and inspect for moisture, rodent damage or accumulated foreign material. Remove any foreign material present. Inspect and tighten any loose terminal connections. Replace any dam- aged or deteriorated wiring.

2.CHECK propellor for freedom of rotation and uniform tip clear- ance. It should also be in- spected for dirt and grain dust, especially inside the hub. Any additional weight can seriously

effect the balance, and result in- harmful vibrations and a short bearing life.

3.CHECK propellor for free play. Any side play is an indication of defective motor bearings, which should be replaced to pre- vent a complete motor failure. Make sure motor mount bolts are tight.

4.Motor bearings should be LU- BRICATED periodically, de- pending on operating condi- tions. Under normal usage it is desirable to have the motor cleaned, checked and bearings repacked by an authorized ser- vice station every two to three seasons. If the unit is operated continuously through most of the

year, this service should be per- formed each year.

Note: If on site bearing relubrication is to be performed, see lubrication instructions for ball bearing motors.

To keep motor bearings properly lu- bricated, and dispel any accumula- tion of moisture within the windings, the fan and auger motors should be operated for 15 to 30 minutes each month.

LUBE PROCEDURES

If the motor is equipped with an alemite fitting, CLEAN the tip of the fitting and apply 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 equipped with slot- ted head grease screw, remove screw and apply grease tube to hole. Insert 2 to 3 inch length of grease string into each hole on motors in NEMA frame and smaller. Insert 3 to 5 inch length on larger motors. On motors having grease drain plugs, remove plug and operate motor for 20 minutes before replacing drain plug.
