PRECAUTIONS TO BE TAKEN BEFORE STARTING THE ENGINE

deadly.

Remove any trace of dirt from the lights, in such a way as to ensure perfect visibility on the work area.
q
Make sure that the work lights have been correctly installed. Make also sure that they come on correctly.

2.3.6 CAB WINDOWS

If a cab window breaks on the side facing the work equipment, this may hit the operator. Therefore, it is advisa-
q
ble to stop the machine immediately and to replace the broken glass.
Check the level of the detergent for the front windshield which has to be an ethyl alcohol based detergent.
q
Do not use a methyl alcohol based detergent as it may irritate the eyes.
2.3.7 CLEANING THE WINDOWS AND CHECKING THE WINDSHIELD
WIPER BLADES
Remove any trace of dirt from the cab windows; this will optimize visibility.
q
Check the conditions of the windshield wiper blades; the scraping wire must be smooth, with no indentations and
q
attached to the rubber back of the blade.
In case of doubt on the efficiency of the scraping wire, change the blades.
