MAINTENANCE
NOTE: Before any maintenance or service is performed, be sure that unit is disconnected from power source to
prevent accidental starting.
MOTOR MAINTENANCE
Removing dust and dirt: Blow off motor with low pressure air to remove dust or dirt. Air pressure above 50 P.S.I. should
not be used, as high pressure may damage insulation and blow dirt under loosened tape. The operator performing this
cleaning function should always wear appropriate eye protective goggles. Built-up dust can cause excessive insulation
temperatures, thereby affecting motor life.
