SERVICE
FAN MOTOR REMOVAL AND INSTALLATION
In the event of motor failure, remove the motor as described, and take it to the nearest service station. An authorized service station is the only place that can provide possible mo- tor warranty. Motor service and re- pair at other places will be at own- ers expense.
If the service station determines motor failure is caused by faulty ma- terial or workmanship within the warranty period, repair will be cov- ered under the warranty. Motor fail- ure caused by external sources will result in a charge to the owner for repair.
1.Make certain power is shut off and locked out. Remove fan guard and propellor.
