14.3 Install the illumination PCB (9.3) into the support plate (9.2) ensuring that the plastic retaining
tabs secure the PCB.
14.4 Install the battery (9.4) into the holder on the PCB, ensuring the correct polarity (Fig 6.2).
14.5 Install the complete illumination module (9) into the centre housing (8.2), pushing down so that it
“snaps” into place.
Left-hand side cover, tilt drag and tilt brake mechanisms
15 Install the left-hand side cover, tilt drag and tilt brake mechanism as follows (Fig 6.5):
15.1 Place the tilt drag shaft (2.6) inside the tilt brake shaft (2.5). Using an M7 allen key, secure the tilt
brake shaft (2.5) into the centre housing (2.4).
15.2 If necessary, lubricate the tilt drag adjuster arm (1) with Kluberlub BE41-501 grease and screw
the tilt drag shaft (2.6) into the tilt drag adjuster arm (1) so the end of the shaft (2.6) is flush with the
adjuster arm (1).
15.3 Install the wave washer (4.1) onto the tilt brake shaft (2.5), and the friction ring (4.2) into the
centre housing (2.4).
15.4 Install two springs (3.3) and two drag adjustment shoes (3.2) in the slots in the centre housing
(2.4).
15.5 If necessary, lubricate the tilt brake sleeve (4.4) with AGIP PV grease and install into the left-hand
side cover (4.3).
15.6 If necessary, separate the adjustable drag disc (3.5) from the fixed drag disc (3.6), clean the
components and apply 4.5 grams of Optalus A0 140 drag fluid (part no. R116,23). Reassemble the two
halves of the drag module (3).
15.7 Install the drag module (3) into the left-hand side cover (4.3) ensuring that the spigots on the
fixed drag disc (3.6) engage with the mating features on the inside of the left-hand side cover (4.3).
15.8 Install the left-hand side cover(4.3) / drag module (3) assembly over the tilt brake shaft (2.5), with
the legs of the adjustable drag disc (3.5) through the slots in the centre housing (2.4) and aligned to the
two drag adjustment shoes (3.2).
15.9 Place two washers (3.4) between the legs of the adjustable drag disc (3.5) and the drag
adjustment arm (1). Install two screws (3.1) and secure the drag adjuster arm (1) to the adjustable drag
disc (3.5).
15.10 If necessary, lubricate the tilt brake nut (5.2
) with Kluberlub BE41-501 grease, install the bearing
(5.1) and screw the left-handed tilt brake nut (5.2) onto the tilt brake shaft (2.5).
15.11 If necessary, lubricate the lock ring (5.3) with Kluberlub BE41-501 grease and using a (UNI 5752)
M 16 pin spanner, screw the (UNI/ISO 2982, 2983) lock ring (5.3) fully onto the tilt brake shaft (2.5).
15.12 Turn the tilt brake nut (5.2) counterclockwise until the tilt brake is fully applied.
15.13 Install the tilt brake lever (5.5) on to the nut (5.2) with the lever approximately 30° - 45° past
vertical, pointing downward toward the rear of the head, or as suitable to the operator.
