Maintenance
Before performing any maintenance on the motor, disconnect electrical power and allow the motor to come
to a complete stop. For safety, wait four (4) minutes. This allows sufficient time for the capacitors to
discharge any residual voltage.
Periodically inspect the installation. Check for dirt accumulation, unusual noises or vibration, overheating,
worn or loose couplings, high motor amps, poor wiring or overheated connections, loose mounting bolts or
guards, and worn motor starter contacts. Check the wiring harnesses and control connectors. Inspect for
shorts, detached wiring, or loose connections.
Remove dirt accumulation, particularly in and around vent openings by vacuuming. Dirt accumulation can
cause motor overheating and is a fire hazard.
Do not
use solvents! Some solvents may attack motor insulation, finish, or bearing lubricants. Solvents are
highly flammable.
Ball bearing motors are permanently lubricated. No maintenance is required.
