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, press the display actuator button and push in and turn the
counterbalance crank to increase or 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 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.
Pan and tilt locks
The pan and tilt friction locks are operated by levers on the left of the head. The locks should be
applied whenever the camera/head is left unattended.
Rotate the pan lock lever clockwise (toward the front of the head) to engage the lock.
Rotate the tilt lock lever counter clockwise (upwards) to engage the lock.
If the lock does not fully engage at the end of the lock lever travel, refer to "Adjusting The Lock
Levers" in the Servicing section of this manual.
NOTE: If the correct digital balance setting of the payload is known, tilt the platform to
the horizontal position, press the display actuator button and push in and turn
the counterbalance crank until the digital display shows the correct setting.
