MAINTENANCE BASICS WORKING-AREA-DEPENDENT MAINTENANCE MUDDY OR WET WORKING AREAS Immediately clean the machine after work to protect the components against corrosion. Perform maintenance and lubrication measures more fre- quently when working in areas with unfavourable working conditions. If the machine is used in water, lubricate bolts daily - see "Lubrication". DUSTY WORKING AREAS Adhere to the following measures when working in dusty work- ing areas: Pay attention to the warning lamp of the air filter to detect a blocked air filter insert in time. In addition, clean the air filter insert more frequently than specified in the maintenance schedule.
Frequently clean the external surfaces of the radiator to en- sure unobstructed flow of air. Replace the fuel filter cartridge more frequently than speci- fied in the maintenance schedule. Clean all electrical components, especially the starter and the generator. 7-4
