33.1 Turn the pan drag knob fully counterclockwise.
33.2 Operate the pan brake lever (16) from the OFF to the ON position.
33.3 Brake pressure should be felt after approximately one-third of the lever travel. Turn the pin (5)
clockwise to decrease the amount of lever travel, counter-clockwise to increase.
33.4 Operate the pan brake lever (16) to the OFF position and ensure that the head is free to rotate.
Pan bearing
34 The pan bearing is adjusted by tightening or slackening nut (47), using pan bearing nut key (Vinten Part
No. 3448-902TL). Adjust the pan bearing as follows
34.1 Fully tighten nut (47).
34.2 Fit a 70 kg payload to the head.
34.3 Apply the tilt brake.
34.4 Turn the pan drag knob fully counterclockwise.
34.5 Turn the head through 360° in both directions and ensure no noise or rumble is perceptible in the
pan bearing. Slacken nut (47) to achieve this condition if required.
34.6 With a finger on the gap between the mounting plate (20) and the brake reaction plate (22), rock
the head using the pan bar and ensure no movement is perceptible between the mounting plate and
the reaction plate. Tighten nut (47) to achieve this condition.
34.7 Repeat paras
34.8 Remove the payload.
Balance mechanism bushes
35 The balance mechanism bushes (6) are retained in their housings and adjusted by M5 cap head
screws (3, 30). Screws (3), in the platform pivot blocks (5), are accessible by moving the platform slide fully
rearwards. Screws (30) in the actuators (32, 40), are accessible when the platform is tipped fully back. Adjust
the balance mechanism bushes as follows:
35.1 Turn the tilt drag knob fully clockwise to apply maximum drag.
35.2 Using the pan par, attempt to move the platform and examine each bush (6) for slackness.
Tighten the appropriate screw until all slackness is eliminated, without compromising overall movement
quality
Base cover plates
36 Install the base cover plates as follows
36.1 Position PCB in base, carefully ensuring LED locates in hole and secure with screw (12). Route
battery connector into forward compartment.
36.2 Install switch cover plate assembly (8) and secure with two screws (6).
34.5 and 34.6 until a position is reached where both conditions are achieved.
