If the brake hoses (7), (8), (9) and (10) on the abs control unit are changed or removed, ensure that the fittings on the control unit are positioned correctly.
Warning
If incorrectly positioned, the hose can affect brake operation and foul moving parts. Position the hose as shown in the figure.

Pipes (7), (8), (9) and (10) fixing must be carried out by placing new gaskets (11) between the couplings.
Tighten the screws (17) to the torque of 23 nm +/- 10% (sect. 3 - 3, Frame torque settings).

Check that there are vibration dampers (22) and spacers (13) on the abs supporting bracket (12).
Refit the abs control unit (6) on the supporting bracket (12), and fix it by starting and tightening the retaining screws (16) to a torque of 10 nm +/- 10% (sect. 3 - 3, Frame torque settings).

Connect the connector (a) of the abs control unit (6).

If removed, refit the front rubber pad (15) applying the recommended threadlocker to the pin (c) and the rear face of the pad. Fit the pad inserting pin (c) into the corresponding hole (d).

If removed, refit the rear rubber pad (15) applying the recommended threadlocker to the cover of the exhaust valve motor until achieving engagement.
Note
The rubber pad (15) must be aligned with the corresponding reference notch (h) as shown.

To fill up the system, carry out the instructions for replacement of fluid of the front and rear braking system master cylinder or calliper to which the pipe is connected (sect. 4 - 3, Changing the brake fluid).
Important
If the abs control unit is replaced, this must be supplied with secondary circuit already full of fluid; the control unit must Be fitted and the system filled and bleeded as a traditional system.

The exhaust side can be identified by the three threaded holes on the flange.
The intake side can be identified by the presence of four threaded holes on
the flange.

Changing and cleaning the air filters
The air filter must be replaced at the intervals described in the "scheduled
maintenance chart" (sect. 4 - 2).
Work on the vehicle right side, loosen screws (1) that secure the intake duct
(2) to the filter box, and the radiator
