HANDCRANKS (CONT)
WARNING
Before performing any maintenance on the platform, lower the front and rear
support legs or injury to personnel may result.
When lowering the support legs, make sure that feet and hands are clear of the
support leg foot as it nears the ground or serious injury to personnel may result.
CAUTION
The socket head screw on the rear landing leg adjusting nut must be positioned
outboard before the cover is closed or damage to equipment will result.
REAR SUPPORT LEG HANDCRANK (2). The rear support legs each contain an adjusting nut (2) and require a ratchet
and socket to lower or raise the support leg lower tube and foot. To lower the support leg, the cover is raised and the
ratchet and socket are used to rotate the adjusting nut (2) counterclockwise to lower the leg to the desired position.
Clockwise rotation of adjusting nut (2) raises the leg. Access to the adjusting nut (2) is obtained by releasing the cover
latch and raising the metal cover sufficiently to engage the adjusting nut with the ratchet and socket. Upon completion of
the rear support leg adjustment, the cover must be put back into position and secured with the cover latch. To prevent in-
transit vibration from rotating the adjusting nut and lowering the rear support leg, a socket head screw is installed on the
adjusting nut which contacts a bar on the cover, preventing movement. Any time the cover is to be closed, ensure the
socket head screw is positioned outboard prior to closing.
