DANGER • Oil spilled on the floor may cause it to become slippery; immediately clean any dirty area.
• Oils, filters, the coolant and the battery are considered special waste and must be collected and disposed of ac- cording to the anti-pollution regulations in force. Before changing the braking system oil, it is advisable to brake a few times in order to warm up and fluidize the oil and therefore facilitate draining. The oil change and the bleeding of the braking system must be carried out with the machine positioned on level ground and locked by means of the parking brake. Drain the oil and wash the system, proceeding as follows: 1 - Apply a small pipe for the collection of the oil to the drain screws (1) and loosen them. Use a 13 mm spanner.
2 - Open the engine hood (See “3.5.1 ENGINE HOOD”) and re- move the cap (2) of the tank (3). 3 - Operate the brake pedals (connected with each other) until the oil contained in the tank (3) runs out. 4 - Fill the tank (3) with new oil and keep pumping; fill the tank (3) more than once, until the used oil (about 0.8 l.) has been changed completely; bleed the residual air. (See “4.7.1.c BLEEDING THE BRAKING CIRCUIT”). For details on the oil to be used, see “4.3 FUEL, COOLANT AND LUBRICANTS”.
