Maintenance Tips

• Clean the Exterior Regularly:
  Dust and debris can clog ventilation openings and cause overheating. Wipe down the motor housing and keep vents clear.

• Inspect Electrical Terminals:
  Ensure all wiring connections are tight and corrosion-free to prevent arcing, voltage drops, or motor failure.

• Verify Correct Voltage Supply:
  Operate only within the rated voltage range (208–230/460V). Over/undervoltage conditions can reduce efficiency and damage windings.

• Check for Overheating:
  Monitor temperature during operation. Excessive heat may signal overloading or poor ventilation.

• Lubricate Bearings (if applicable):
  If your motor requires it, use manufacturer-recommended lubricant and avoid over-greasing. Check schedule in user manual.

• Inspect Mounting and Alignment:
  Ensure the motor is firmly mounted and properly aligned with the driven equipment to prevent wear or vibration.

• Listen for Unusual Sounds:
  Humming, grinding, or knocking noises may indicate bearing or mechanical issues—address immediately.

• Check for Vibration:
  Vibrations can lead to fatigue or damage. Balance load and secure all mounting hardware to minimize movement.

• Protect Against Moisture and Contaminants:
  Operate the motor in a clean, dry environment to avoid rust, insulation failure, or electrical shorts.

• Schedule Routine Inspections:
  Periodically inspect motor windings, connections, and performance for early signs of wear or failure.
