PRECAUTIONS TO BE TAKEN BEFORE STARTING THE ENGINE
37
2.3.4 ROOM VENTILATION
q
Before starting the machine in confined or poorly ventilated
places, provide for proper ventilation or connect the engine
exhaust pipe to a suction duct. The engine exhaust gases
can be deadly.
2.3.5 CLEANING WINDOWS, MIRRORS AND LIGHTS - CHECKING THE
WINDSHIELD WIPER BLADES AND THE BULBS
q
Remove any trace of dirt from the cab windows and the lights and clean the rear-view mirrors; this will ensure
good visibility on the work area.
q
Adjust the rear-view mirrors if they have moved, so that the operator seated in the driving position can clearly
see the area behind the machine.
If any window, light or mirror is damaged, change it.
q
Make sure that the road lights, stop lights, direction indicators and work lights are properly working. If necessary,
change the faulty bulbs with new ones, making sure that their power is correct.
q
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 doubt on the efficiency of the scraping wire, change the blades.
