be felt on the handle with the platform level and with the tilt lock pin
disengaged.

position. The red safety button should engage the platform release
lever.
11. If there is insufficient movement in the sliding plate to achieve balance,

the mounting plate to the camera in the required position, remount the
load and repeat the horizontal balancing procedure.
