motor moves approx. 1/2 revolution and then remains in
closed position.
In this position, the wastegate flap must be completely closed. If necessary,
readjust using the adjusting screw (2). See 78-00-00 of the Heavy Mainte-

Check the wastegate lever (3) for free movement.
NOTES: If it does not move freely, lubricate the axle (lubrication hole)
of the wastegate with LOCTITE Anti-Seize 8151, ROTAX
part no. 297434.
