REFUELLING AND TOPPING UP OF OIL
Spilled fuel or oil involves danger of slipping and fire. For this reason,
immediately remove any spilled liquid.
Always refuel and top up oil in a place that is sufficiently ventilated.
After refuelling and topping up, 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. Dis-
pose of used substances according to the relevant environmental
regulations.
If the machine is provided with a fuel sieve in the tank opening, do not
remove this fuel sieve before you start refuelling.
COOLANT
The machine is provided with an aluminium cooling system. Apply
only coolants in the prescribed mixing ration.
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.
USE OF LIGHTING
Always use explosion-proof lighting when checking fuel, oil, coolant, or
battery acid.
