This section contains Instructions for the safe use of the Ground Handling Wheels Assembly under usual conditions. The
instructions presented in this section include preparation for use, installing wheels assembly on helicopter, lifting the
helicopter, lowering the helicopter, and removal of wheels assembly from helicopter. Unusual operating conditions are
defined and described in Section IV of this Chapter.
2-10. PREPARATION FOR USE.
Perform all Before PMCS procedures in Table 2-1 before using the Ground Handling Wheels Assembly. The DA Form

Wheels Assembly can be safely used to raise a helicopter off the ground.
2-11. INSTALLING GROUND HANDLING WHEELS ASSEMBLY ON A HELICOPTER.
The Ground Handling Wheels Assembly is installed on a helicopter as follows:
The lifting lugs are located on the helicopter skids just aft and forward of the center of
gravity of the helicopter, to provide a "near balance" condition for ground handling
and/or moving the helicopter.
Position the Ground Handling Wheels Assembly over the helicopter skid tube, and insert the nose pin into
rear lifting lug.
Rotate the cradle downward until the forward helicopter lifting lug is fully seated in the rear cradle clevis.
Press and hold in the locking button of the quick release pin. Insert the pin into the cradle making sure the
pin passes through both sides of the rear clevis and the helicopter lifting lug. When locking balls are
visible, release the locking button.
2-12. LIFTING THE HELICOPTER FOR GROUND HANDLING.
The Ground Handling Wheels Assembly is used to lift the helicopter as follows:
Grip only the pump handle when operating the hand pump. Never operate the hydraulic
pump without the metering valve installed in the pump outlet. This valve controls the
rate of descent when lowering a helicopter after use Lack of a metering valve could cause
damage to the helicopter and/or injury to personnel.
