When the motor is hanging in the lifting
accessory, and the pinion no longer is
mated to the gear, let the outer end of the
motor hang lower so that it will hang in an
angle. This position makes it easier to re-
move the axis-3 motor with the axis-4 mo-
tor still fitted.
CAUTION
The pinion must have been parted from
the gear before the motor is angled. If not
there is a risk of damaging the pinion and
gear.
