  2.8.3  Filling Grease to Reduction Gear 
  When the reduction gears are used under the normal operating conditions, regular 
greasing of them is unnecessary.    Replace the reduction gears at the time of 
overhauling.    For the axes 1 and 2, however, if the reduction gears are used under 
the conditions of high operation duty and heavy load, fill the grease to them every 
10,000 hours (i.e., approximately two (2) years).    Greasing of the axis 4 reduction 
gear is unnecessary. 
 
•  When the grease has run short, cut or scratch will be caused on the reduction 
gear interior or gear, resulting in drop of the performance.    To avoid this, take 
careful precautions to prevent shortage of the grease. 
•  Be sure to use the grease designated by Toshiba Machine. 
•  Increase in internal pressure will adversely affect the starting torque and 
damage the internal seal.    To avoid this, be sure to observe the grease filling 
volume.
