OPERATION
3. Press the spindle speed range lever shown
in Figure 32 toward the head to release
the detent pin from the detent plate, move
selector so that the pin is over the other
detent, then release the selector.
— When the selector is pointing to the rear
and the front detent is engaged, the low
speed range is selected. Conversely, when
the lever is pointing toward the front and
the rear detent is engaged, the high speed
range is selected.
Note: If it is difficult to move the range selector,
rotate the spindle by hand to help mesh the
gears until the selector moves freely.
Setting SB1024 Spindle Speed Range
1. Make sure that the spindle rotation is

range that includes the required spindle
speed for your operation.
