2.3.3 Attachment of Transported Objects
y Attach a transported item on the threaded area on the tip of the rod. Keep in mind of the
incomplete thread.
y When tightening, hold two faces with an open-end wrench so torque would not be applied on
the rod. Applying excessive torque to the rod may damage the components inside.
y The material of the rod is aluminum. Tighten the Enclosed nut with the Recommended
tightening torque described below. Excessive tightening torque may damage the threaded area.
