1. Replace the wheel and measure the distance between the backplate
of the drive unit and the pedestal as shown.
Note: If the wheel is bent or not running true, the distance will change
with the wheel position. Measure the smallest distance.
2. Cut the pin 11†mm (0.4†in) longer than dimension A. Remove any
burrs and fit the plastic cap (supplied) over the cut end.
3. Slide the wheel forward and place the pin end with the plastic cap in
Slot 1 if mounting the actuator on an unobstructed pedestal.
ïThe motor will be as shown in the first diagram.
ïControls mounted on the pedestal might prevent installation of
the actuator to Slot 1.
ïFit the pedestal bracket pin in Slot 2 ñ the motor will be on the
other side of the pedestal and higher up (as shown in diagram
two).
ïIf there is a compass mounted in the pedestal, check that
running the motor does not affect compass readings when Slot
2 is used.
