Payload Weight And Counterbalance; Pan And Tilt Locks - oConnor 1030D Operator's Manual

Operators Guide
8. Carefully slide the camera payload and platform forwards or backwards, until the
payload is balanced fore and aft. The horizontal balance is correct when no perceptible
tilting force can be felt on the handle with the platform level and the tilt lock disengaged.
9. Lock the platform to secure the balanced camera payload in position. Engage the
platform release lever by pushing it firmly towards the platform.
10. If there is insufficient movement in the platform to achieve balance:
Determine in 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.
11. The camera mounting plate is marked and the head has scales on both sides; make a
note of the "balanced" position to simplify rebalancing this particular payload.

Payload weight and counterbalance

The fore and aft balance must be set before adjusting the payload weight and counterbalance.
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 necessary, adjust the counterbalance as follows:
• If the head tends to fall away when the platform is tilted, set the platform level and
turn the crank handle clockwise to increase the counterbalance.
• If the head tends to spring back when the platform is tilted, set the platform level and
turn the crank handle counterclockwise to decrease the counterbalance.
3. Using the handle tilt the platform upwards and downwards to recheck the balance.
Adjust the counterbalance, until balance is achieved.
4. When balancing is complete, check that the fore and aft balance is still correct. Readjust
the position of the platform, if necessary.
5. Exercise the head through the full range of pan and tilt to confirm that it operates
smoothly.

Pan and tilt locks

The pan and tilt friction locks are operated by levers on the left side of the head.
Rotate the pan lock lever clockwise to engage the pan lock.
Rotate the tilt lock lever counterclockwise to engage the tilt lock.
CAUTION! The locks should be applied whenever the camera/head is left unattended.
If a lock does not fully engage at the end of the lock lever travel, refer to 'Adjusting the lock levers'
on page 16 in the Servicing section.
