11. Fully engage the platform release lever to secure the payload in position. The red safety
button should engage the platform release lever.
12. If there is insufficient movement in the sliding plate to achieve balance, determine which
direction the mounting plate needs to be moved to achieve correct balance. Remove the
payload from the head, reattach the mounting plate to the camera in the required position,
remount the load and repeat the horizontal balancing procedure.
13. The sliding plate is marked and the platform has graduations. Make a note of the "balanced"
position to simplify rebalancing this particular payload.
Payload Weight and C of G Height Adjustment
The fore and aft balance must be set before adjusting the payload weight and C of G height
adjustment.
1. Using the handle, tilt the platform downwards and upwards. When correctly balanced, there
should be no perceptible tilting force on the handle at any angle of tilt and the head should
remain in any tilt position to which it is set.
2. If the head tends to fall away when the platform is tilted, the counterbalance will need to be
increased. If the head tends to spring back when the platform is tilted the counterbalance
will need to be decreased.
3. Set the platform level, unfold the counterbalance crank handle and turn it clockwise to
increase or counter-clockwise to decrease the counterbalance setting as required.
4. Using the handle, tilt the platform upward and downward to recheck the balance. Readjust
counterbalance until balance is achieved.
5. Make a note of the final numeric counterbalance setting to simplify rebalancing this particular
payload.
6. When the payload weight and C of G height adjustment is complete, check that the fore and
aft balance is still correct. Re-adjust the position of the sliding plate if necessary.
7. After balancing, exercise the head through the full range of pan and tilt to confirm that it
operates smoothly.
Locking the Platform
The tilt lock pin mechanism is operated by a flip lever on the left-hand side of the head. To
engage the pin, hold the platform in the horizontal position and flip the lever over from the green
position to the red position. If necessary, use the handle to rock the head slightly to achieve the
fully locked position. The pin and flip lever will snap towards the platform as the pin engages.
To release the tilt lock pin, flip the lever over from the red position to the green position. If the
platform is not balanced this may require force. If so, make sure that the tilt lock lever is rotated
clockwise to hold the platform in place.
NOTE: If the correct numerical balance setting of the payload is known, tilt the
platform to the horizontal position and turn the counterbalance crank until the
numerical display shows the correct setting.
