Fore and aft balance
When positioning the payload it is important to be aware of the potential danger of an unbalanced
payload falling away suddenly. Before disengaging the centre lock, push in and turn the balance
adjustment knob (8) to its mid point setting. Depending on the payload weight, it may be necessary
to increase or decrease this setting to enable the payload to be correctly balanced fore and aft.
Balance the payload fore and aft as follows:
Ensure that the centre lock is engaged (see Locking the platform) and that the camera and
all accessories are fitted.
Turn the tilt drag adjustment knob (16) to its minimum setting.
