Fore and aft balance

1.

Make sure the tilt lock is engaged and that the camera and all accessories are installed 
in their operating positions.

2.

Set the tilt drag adjustment knob to ‘1’ (lowest setting).

3.

Initially, set the counterbalance quite low. 

4.

Holding the handle to steady the platform, disengage the tilt lock. 

5.

Tilt the platform forwards and backwards and determine whether the camera payload is 
front or back heavy. Depending on the payload weight, it may be necessary to adjust the 
counterbalance to enable the payload to be correctly balanced fore and aft.

6.

If it is not in balance, re-engage the tilt lock.

7.

Disengage the platform release lever by pulling it away from the platform.

WARNING!

When positioning the payload, it is important to be aware of the potential 
danger that an unbalanced payload will fall away suddenly. 

Always be prepared for this by maintaining a firm hold of the handle, until 
the balance is set correctly.

WARNING!

In the event of the head falling away violently, increase the counterbalance 
setting.
