MAINTENANCE
Maintenance & Repair:
Use only genuine Allegro approved, replacement parts for maintenance and repair.
Use of parts manufactured by others can result in property damage and/or personal
injury.
Follow the service instructions as outlined in the Maintenance section of this Users
Manual.
Always properly maintain the blower. Frequently check all fasteners and individual
parts. Built-in safety features are effective only if they are maintained in good
working condition. Keep the blower clean and properly serviced. Heavy
accumulations of dust and dirt will result in overheating and premature failure of the
blower motor. Clean the motor surfaces and all ventilation openings periodically.
Always stop the motor and disconnect the power source to prevent the accidental
starting and/or the possibility of receiving an electrical shock working on the blower.
Do not energize the electric motor with the shaft key exposed on the open shaft.
Personal injury can result from being struck by a shaft key thrown from the motor
shaft.
DANGER!
Always stop the motor and disconnect the power source to prevent the accidental
starting and/or the possibility of receiving an electrical shock.
Do not attempt any maintenance or repair work not described in this Users Manual!
Electric Motor Maintenance:
The electric motor is capable of operating for many years with minimum
maintenance.
Before attempting to service the motor, disconnect the blower from the power
supply.
Clean the motor surfaces and ventilation openings periodically, preferably with a
vacuum cleaner. Heavy accumulation of dirt and lint will result in overheating and
premature failure of the motor.
The electric motor is equipped with ball bearings, and under normal service and
ambient temperatures, should not require re-lubrication for 9 to 10 years. If you feel
that the motor requires re-lubrication, contact the local service representative of the
motor manufacturer for specific information.
