PRECAUTIONS TO BE TAKEN BEFORE STARTING THE ENGINE 2.3.4 ROOM VENTILATION Before starting the machine in confined or poorly ventilated places, provide for proper ventilation or connect the engine ex- haust pipe to a suction duct. The engine exhaust gases can be deadly. RWA01050 2.3.5 CLEANING WINDOWS, MIRRORS AND LIGHTS - CHECKING THE WINDSHIELD WIPER BLADES AND THE BULBS Remove any trace of dirt from the cab windows, lights and rear-view mirrors, in order to ensure perfect visibility. Adjust the rear-view mirrors if they have moved, so that the operator sitting in the driving position can clearly see the back of the machine. If any window, light or mirror is damaged, change it.
Make sure that the road lights, stoplights, direction indicators and working lights are properly working. If neces- sary, change the faulty bulbs with new ones, making sure that their power is correct. Check the conditions of the windshield wiper blades; the scraping wire must be smooth, with no indentations and attached to the rubber back of the blade. In case of doubts on the efficiency of the scraping wire, change the blades. 34
