SAFETY MEASURES DURING MAINTENANCE 11.3.5 REFUELING AND TOPPING OFF OIL Spilled fuel or oil involves danger of slipping and fire. For this reason, immediately remove any spilled liquid. Always refuel and top off oil in a place that is sufficiently venti- lated. After refueling and topping off, close the filling openings with cover caps. Do not use fuel for rinsing or cleaning of components. Ensure that neither oil nor fuel can seep into the soil or water. Dispose of used substances according to the relevant environ- mental regulations. If the machine is provided with a fuel sieve in the tank opening, do not remove this fuel sieve before you start refueling.
11.3.6 COOLANT The machine is provided with an aluminium radiator. Use cool- ants only in the prescribed mixing ratio. Caution, antifreeze is highly inflammable. To check the coolant level, first switch off the engine and wait for the cooling system to cool down. Then, check the coolant level in the expansion tank. Slowly unscrew the cap to let the pressure escape. If required, top up water in the expansion tank. 39
