The spindle direction switch controls a three-phase
motor. The motor can be switched from forward to
reverse and back with the motor running, and will
reverse direction when the switch setting is
changed. At higher speeds, this may put strain on
the timing belt but there will be no damage to motor
or gear mechanism. However, it is recommended
that switch be placed at neutral position and spindle
allowed to come to a stop, then switch moved to
opposite direction.
