Using a pipe cleaner (or similar) moistened with an isopropanol-based cleaner (3M VBH
or similar) clean the two vertical tracks [32]. Upward pressure on the balance
mechanism will allow the area of track under the vertical rollers to be cleaned.
Reinstall the platform [17] on the balance mechanism [31] and secure with six screws
[30] using Loctite 222E.
Using the slide plate adjustment knob (Tommy bar) [14] wind the slide plate [20]
forwards to the central position.
Refit the payload (if required).
Horizontal tracks
No dismantling is necessary to clean the horizontal tracks (Fig. 8).
Proceed as follows:
Remove the payload (if fitted).
Set the balance mechanism to its maximum setting by pushing in the Perfect Balance
adjustment knob [21] and turning it clockwise to its stop.
Tilt the platform [17] fully backwards and apply the tilt brake [4].
Pull down the flap guard [35] to reveal the bevel gear [33]. Access to the horizontal
tracks [34] is through the holes in the bevel gear, which may be rotated freely.
