LR IMPORTANT NOTE: Procedure involves parts with limited reusability. Check parts list below
before starting job!
PRECAUTIONS AND SAFETY MEASURES
WARNING: Wear eye protection and mind FOD when removing attachment hardware!
WARNING: Object is heavy! Inadequate handling could cause injury. Use proper lifting techniques or
assistance!
WARNING: Never place the rotor system on a dirty or grainy surface and avoid bending moments at the
blade attachments!
WARNING: When handled incorrectly the rotor system can be damaged irreparably. If undetected this
may have catastrophic consequences!
CAUTION: When removing or disassembling make sure to mark all parts so that each and every part of
the component is re-assembled and installed in exactly the same location and orientation!
IMPORTANT NOTE: Some rotor blades have loose washers in them which are required as balance
weights. Do not remove or restrain if present!
PROCEDURES
1 Secure the gyroplane on level ground by engaging the parking brake, adjust the rotor system lengthwise and
pump up the rotor brake to its maximum.
2 Remove and discard split pin and unscrew the castellated nut (4). The rotor system has to be tilted onto the
black rotor teeter stop.
3 The teeter bolt (1) has to be extracted by using only the hand, not a hammer. If needed tilt the rotor blades
carefully onto the teeter stop, in order to prevent the bolt from jamming. Make sure that the rotor stays level
in the teeter axis, if not the teeter bolt will damage the Teflon coated bushes, while being pushed out.
4 A supervised second person has to hold the rotor system in flying direction.
5 Lift the rotor system carefully out of the teeter tower and be aware of the position of the shim washers (2).
Their thicknesses may differ and it is essential that they are reinstalled on the correct side! They are marked
with dots to identify the correct side.
6 Remove the rotor system to one side by letting it rest on your shoulder and take care not to collide with
stabilizer or propeller.
7 The shim washers and the teeter block in the hub are marked on each side with one or two engraved dots.
Directly after the disassembly the shim washers need to be fixed on their respective side with cable ties.
8 If possible, handle with two persons while holding approximately in the middle of each blade. When
supporting the system use two stands each positioned in about 2 metres distance from the hub.
9 The rotor system must not be placed on a dirty or grainy surface, as the blades can scratch and damage
easily. The best way is to place the rotor blades centrally onto two stands, supporting the rotor at
approximately 2 m distance from the hub.
