Seasonal Inspection and Service
The dryer is made of weather resistant material, and is designed to require a minimum of service.
However, each season we recommend the following 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 operation of the equipment.
1. Shut OFF 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 damaged or deteriorated wiring.
2. Check propeller for freedom of rotation and uniform tip clearance. It should also be inspected for
dirt and grain dust, especially inside the hub. Any additional weight can seriously affect the balance,
and result in harmful vibrations and a short bearing life.
3. Check propeller for free play. Any side play is an indication of defective motor bearings, which
should be replaced to prevent a complete motor failure. Make sure motor mount bolts are tight.
4. Motor bearings should be lubricated periodically, depending on operating conditions. Under normal
usage it is desirable to have the motor cleaned, checked and bearings repacked by an authorized
service station every two to three seasons. If the unit is operated continuously through most of the
year, this service should be performed each year.
NOTE: If on site bearing relubrication 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.
