Cleaning balance mechanism track
4 The balance mechanism tracks are automatically cleaned by built-in wipers, but after use in particularly
adverse conditions the tracks may require cleaning. Some dismantling of the head is necessary and it is
recommended that this be carried out in clean workshop conditions.
Vertical tracks
5 To clean the vertical tracks it is necessary to remove the platform. Proceed as follows (Fig 4.1):
5.1 Remove the payload (if fitted). It is not necessary to remove the wedge adaptor.
5.2 Release the sliding plate clamp (9). Use the adjustment knob (10) to wind the sliding plate(3)
backwards until it is clear of fixing screws (1).
5.3 Level the platform.
5.4 Remove six screws (1) securing the platform (2) to the balance mechanism (4). Lift off the
platform.
5.5 Using a pipe cleaner (or similar) moistened with an isopropanol-based cleaner (3M VBH or
similar), clean the two vertical tracks (11). Upwards pressure on the balance mechanism will allow the
area of track under the vertical rollers to be cleaned.
5.6 Install the platform (2) on the balance mechanism (4) and secure with six screws (1), using
Loctite 222E.
5.7 Using the adjustment knob (10) wind the sliding plate forwards to the central position.
5.8 Refit the payload (if required) and rebalance the head.
Horizontal tracks
6 No dismantling is necessary to clean the horizontal tracks. Proceed as follow (Fig 4.1):
6.1 Remove the payload (if fitted). Set the balance mechanism to its maximum setting by pushing in
the knob (8) and turning it clockwise to its stop.
6.2 Tilt the platform fully backwards and apply the tilt brake (7).
6.3 Pull down the flap guard (6) to reveal the bevel gear (5). Access to the horizontal tracks is
through the holes in the bevel gear, which may be rotated freely.
6.4 Using a pipe cleaner (or similar) moistened with an isopropanol-based cleaner (3M VBH or
similar), clean the two horizontal tracks. Upwards pressure on the balance mechanism will allow the
area of track under the horizontal rollers to be cleaned.
6.5 Release the flap guard (6) and the tilt brake (7) and return the platform to the horizontal position.
6.6 Refit the payload (if required).
