1 Machine speed & direction in which the machine pulley runs    

Refer to the table below for maximum and standard 
speeds of the Series.  To extend machine life, run 
the machine approximately 15~20% below the 
maximum speed for the first 200 hours of operation 
(approx. 1 month).  Then run the machine at the 
standard speed.  The machine pulley turns 
counterclockwise as seen from the end of the 
machine pulley.

Motor    :    3-phase, 2-pole, 400W clutch motor 
Belt 

  :    M type V belt 

Select the proper motor pulley according to the 
machine speed (refer to the motor pulley outer 
diameter on the table below).  Adjust where to 
position the motor by pressing the finger onto the 
middle of the belt so that 1~2cm deflection can be 
obtained (see the illustration on the right).
