Ensure that the centre lock is engaged (see Locking the platform on page 20) and that the cam-
era and all accessories are fitted.
Turn the tilt drag adjustment knob (18) to minimum.
Push in and turn the balance adjustment knob (5) to its mid point setting.
WARNING! Be prepared to prevent the head falling away suddenly when disengaging
the centre lock. In the event of the head falling away violently, increase the
setting on the balance adjustment knob (5).
Holding the pan bar to steady the platform, disengage the centre lock (see Locking the platform
on page 20).
Release the sliding plate clamp (16) and pull out the sliding plate adjustment knob (2) until it en-
gages with the platform drive. Turn the knob to move the sliding plate fore and aft to achieve hor-
izontal balance.
NOTE: The sliding plate is graduated to facilitate balancing. If the balance setting of the payload
is known, turn the knob until that setting is reached.
The horizontal balance is correct when no perceptible tilting force can be felt on the pan bar with
the platform level. Apply the sliding plate clamp (16) and push in the adjustment knob (2) to its
stowed position.
If there is insufficient movement in the sliding plate to achieve balance, reposition the wedge adap-
tor (see Repositioning the wedge adaptor on page 23), refit the load and repeat the horizontal
balancing procedure.
The sliding plate is graduated. Make a note of the position to facilitate rebalancing this particular
payload.
Payload weight and C of G height adjustment
When fore and aft balance has been achieved, carry out the payload weight and C of G height adjustment
as follows:
NOTE: If the digital balance setting of the payload is known, push in and turn the balance knob
(5) until the digital display (11) shows that setting.
Using the pan bar, tilt the platform forward and backward. When correctly balanced, there should
be no perceptible tilting force on the pan bar at any angle of tilt and the head should remain in any
tilt position to which it is set.
NOTE: Setting the platform level will facilitate adjusting the balance setting
If the head tends to fall away when the platform is tilted, set the platform level and push in and turn
the balance adjustment knob (5) clockwise to increase the balance setting. If the head tends to
spring back to centre, set the platform level and push in and turn the balance adjustment knob (5)
counter-clockwise to decrease the balance setting.
When the payload weight and C of G height adjustment is complete, check that the fore and aft
balance remains satisfactory. Re-adjust the position of the sliding plate if necessary.
The digital display (11) will display the balance setting while balance is being adjusted. Make a note
of the final setting to facilitate rebalancing this particular payload.
After balancing, exercise the head through both axes to confirm that it operates smoothly.
