As you tighten the tensioning bolt, the 

shafts will straighten and apply more 
tension to the belts. The correct amount of 
belt tension is when there is approximately 

1

" deflection with moderate pressure 

applied to the belt between the pulleys (see 
Figure 50).

Do not overtighten the belts—this 

could cause the machine to run hot and 
cause damage to the motor and bearings.

When spindle rotation is started with the spindle 
switch, the spindle speed is selected by rotating 
the spindle speed dial (see Figure 51) until the 
tachometer display shows the desired spindle 
speed.

The rate that the carriage moves when engaged 
with the longitudinal leadscrew for power feed 
or threading operations is controlled by the 
configuration of the timing belts and pulleys (see 
Figure 52).

The timing belt and pulley configurations for 
the available feed rate and threading options 
are displayed in the chart on the front of the end 
cover (see Figure 53).
