LUBRICATION Back to Index The accuracy and very life of the machine depend on correct lubrication . The chart on the opposite page provides information regarding the points which require frequent attention, and it cannot be too strongly stressed to the operator to the daily attention is necessary to ensure efficient functioning of the machine. When a machine leaves our plant, the Headstock and Feedbox are filled to the proper oil gauge level with the recommended lubric ant.

Always stop the machine when checking the oil levels to give the oil an opportunity to settle so that a true reading may be taken. If this is not done overfilling may take place resulting in excessive heat and waste of oil by leakage. Oil levels should be checked weekly. Thirty days after the machine goes into operation the Headstock and Feedbox should be drained flushed with clean flushing oil and refilled with the recommended oil to the proper levels.
The motor bearings should be checked periodically to see that they are packed with grease of the grade recommended by the manufacturers of the motor on your machine. The Coolant Pump motor bearings should be checked periodically to see that they are packed with water repellant grease. WIRING TO POWER SUPPLY
