FAN SERVICE

 

 

Motors used in GSI fan units are all standard NEMA frame motors and are specially designed for use in crop drying applications. Most of the replace- ment parts for these motors are handled by authorized service stations of the various motor manufacturers.

1.Always disconnect and lock out power before working on or around fan motor and electrical components.

2.Malfunctioning electrical components should be checked by a qualified electrician.

3.For extra motor life, any electric motor should be run for 30 minutes, once a month. This will help eliminate any damaging mois- ture build-up in the motor and bearings.

4.If excess vibration shows up at some point when the fan has been running smoothly, check the blade for these conditions:

a.Fans setting idle in the summer offer an excellent place for mud dobbers to build their nests. A mud dobber nest on the back of the fan blade will cause the fan to be out of balance and vibrate.

b.

Also, mice have been

known to

nest in

the back

of a blade.

When the fan is

started the centrifugal force kills the mice, but throws the blade out of balance.
