35.2 Operate the pan brake between the 'ON' and 'OFF' positions. Ensure that in the 'ON' position the
brake is on, the head cannot be rotated and the brake lever is in the fully rearward position. Ensure that
in the 'OFF' position the brake is off, the head is free to rotate and the brake lever is in the fully forward
position.
35.3 Screw pin (14) in or out to achieve above condition.
Pan bearing (Fig 6.4)
36 The pan bearing is adjusted by tightening or slackening screw (24). Adjust the pan bearing as follows
36.1 Mount the head on a suitable mount that will support the head and payload and allow access to
screw (24). A Vinten HD1 heavy-duty tripod is recommended.
36.2 Fit a 70 kg payload to the head.
36.3 Apply the tilt brake.
36.4 Turn the pan drag knob fully counterclockwise.
36.5 Turn the head through 360 ° in both directions and ensure no noise or rumble is perceptible in the
pan bearing. Slacken screw (24) to achieve this condition if required.
36.6 With a finger on the gap between the four-hole mounting plate (22) and the brake reaction plate
(25), rock the head using the pan bar and ensure no movement is perceptible between the mounting
plate and the reaction plate. Tighten screw (24) to achieve this condition.
36.7 Repeat paras 35.5 and 35.6 until a position is reached where both conditions are achieved.
36.8 Remove the payload.
Balance mechanism bushes
37 The balance mechanism bushes (6) are retained in their housings and adjusted by M5 cap head
screws (3,33). Screws (3), in the platform pivot blocks (5), are accessible by moving the platform slide fully
rearwards. Screws (33) in the actuators (34, 42), are accessible when the platform is tipped fully back. Adjust
the balance mechanism bushes as follows:
37.1 Turn the tilt drag knob fully clockwise to apply maximum drag. Allow drag to stabilize.
37.2 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
38 Install the base cover plates as follows
38.1 Position PCB in base, carefully ensuring LED locates in hole and secure with screw (9). Route
battery connector into forward compartment.
38.2 Install switch cover plate assembly (8) and secure with two screws (5).
38.3 Connect the battery and position in forward LH compartment. Install LH cover plate (23) and
secure with three screws (5).
