During transportation, storage or installation the grease inside the bearings will settle. If the spindle is suddenly run at high-speed excessive
heat will cause bearing damage. After installation, repair, initial operation, or long periods of non operation please follow the break-in

should not exceed 20 degrees C (36 degrees F) above ambient
temperature. Should the motor spindle exceed this limit, rest
the motor spindle for at least 20 minutes and re-start the break
in procedure from the beginning. If the housing temperature
rises again and exceeds 20 degrees C (36 degrees F) above
ambient temperature, check the motor spindle for proper
installation.
