Select one of the three downfeed rates
by pulling the knob of the auto-downfeed
rate selector out, position the selector over
the appropriate detent, then release the
knob. Make sure the pin is firmly seated
by attempting to move the selector without
pulling the knob out.
Note:
Refer to the illustration in Figure 43 when
selecting the downfeed rate.

Use the coarse downfeed lever to lower the
spindle slightly until you can pull the clutch
lever out to the left and it locks in place,
which will start the auto-downfeed spindle
travel.
To avoid the risk of gear damage, always
start spindle rotation before using the auto-
downfeed rate selector.

Spindle Brake
After turning the power to the spindle OFF,
move the brake lever back or forth to bring the
spindle to a full stop (see Figures 44–45).
To evenly wear the brake shoes, alternate the
direction you move the lever when braking.
To avoid premature wear of the brake system,
use the spindle brake ONLY after power to the
spindle has been turned OFF.
