With the motor head unit on
the edge of the steel tube,
align the two drive hooks
on the driving wheel, so that
it will brace against one of
the spokes of the spool
wheel.
With the motor gearbox
disengaged, push the
motor onto the tube until it
is supported on the tube.
Do not yet push it against
the spool wheel.
