Secure each knob with a screw (18) and washer (17) with Loctite 222E. Secure cap (19) to each knob
with Silcoset.
13.4 Lubricate the thrust washer components (10) with white bearing grease and install in outrigger
(9), ensuring orientation is as noted during disassembly.
13.5 Lubricate the tilt drag knob boss (11) with M204G grease and install, complete with drag knob
retaining shaft (14), in the thrust bearing (10). Secure with tilt drag retainer/stop (27) and three screws
(26).
13.6 Turn the tilt drag boss (11) clockwise until any slack is taken up, then turn the outrigger in both
directions to confirm that movement is smooth and quiet. Degrease thread in drag knob retaining shaft
(14).

Platform

15 To install the platform, proceed as follows
15.1 If removed, install dowel pin (40) in platform (39) to leave the end projecting 3.5mm. Loctite 601
may be used to secure the dowel pin if required.
15.2 Degrease two threaded holes in the top face of tilt housing (24), two threaded holes in the edge
of platform (39), two screws (23) and two screws (8).
15.3 Support the head securely in an upright position and set the top surfaces of the tilt drag housing
and the RH side plate approximately level.
15.4 Locate slide clamp strip (10) in the slot in the underside of the platform and hold it in position
using the rounded end of tool
release (26) downwards through the hole in the platform to locate in the underside of the platform.
Ensure that the slide release is free to move and is inserted with its slot towards the centre of the
platform.
15.5 Holding the slide release in the fully out position, tilt the RH edge of the platform down and
engage the lug on the side of the platform in the notch in the RH side plate. Lower the LH side of the
platform into position on the top face of the tilt unit housing, ensuring that the lugs on the underside of
the platform enter the corresponding slots in the top face of the tilt unit housing and the 2mm dia Spirol
pin in the top of the tilt unit housing enters the slot in the slide release. Remove tool 3390-909TL.
15.6 Position spring (28) on the cylindrical end of tool 3390-909TL. Holding the tool so that the
cylindrical end points slightly downward, lift the LH side of the platform just enough to allow the spring
to be introduced between the top face of the slide release and the underside of the platform. Use the
tool to guide the free end of the spring into the slot in the slide release, compress the spring against the
2mm dia Spirol pin until its outer end drops into the slot in the slide release, lower the platform to rest on
the tool and withdraw the tool.
15.7 Apply Loctite 222E to two screws (23) and two screws (8) and secure the platform to the RH side
plate and the tilt unit housing.
15.8 Confirm that the slide release operates freely and that the spring returns it to the outward
position.
