SAFETY MEASURES DURING OPERATION 10.1.3 IN-DOOR OPERATION Do not operate machines in-door unless these areas are suffi- ciently ventilated (e.g. workshops). Caution - Danger of intoxication! 10.1.4 GAS, DUST, AND INFLAMMABLE VAPOURS Do not operate combustion engines in an environment that may contain inflammable gases or vapours. These gases, dusts, or vapours may ignite or be sucked in by the suction system, thus causing a rise in engine speed or an exceeding of the engine's maximum rpm. This may lead to a fire, an explosion, and major damage to property. It may also happen that the engine cannot be switched off anymore. Also refer to chapter "10.1.3 In-Door Opera- tion".
10.1.5 MIRRORS, WINDOWS, AND LIGHTING Clean the windows and the headlights to ensure maximum sight. Adjust the rear-view mirror in such a way that you have an excellent view of the rear from the driver's seat. Keep the mirrors clean. Ensure that the complete lighting system operates properly and that it is correctly adjusted. Immediately replace broken window panes by new ones. 27
