OPERATING INSTRUCTIONS Inspection and servicing If the cooling-liquid level is too low, a warning lamp on satellite I lights up.
COOLING SYSTEM 2804253
The cap (2) is accessible from above.
Read and observe: "Inspection and servicing - Safety instructions".
Secure the machine as described in the "Securing the machine" section. Shut off the engine and allow to cool down. Risk of scalding from hot cooling liquid. Collect escaping cooling liquid and discard without polluting the environment. Protect the skin from contact with cooling liquid. Skin contact with cooling liquid is a potential health hazard.
Risk of scalding from hot cooling liquid. Open radiator cap cautiously.
Ü Turn radiator cap (1) back to the first notch. Ü When the pressure has been released turn cap into the "open" position and remove. The cooling-liquid level should reach up to the lower edge of the filler tube. Top up with cooling liquid, if required. Fill cooling liquid into the cooling system through the filler tube. Do not fill in cold cooling liquid when the engine is at operating temperature.
Wear protective gloves and firm working clothing.
Temperature The cooling-liquid circuit is controlled by a thermostat. The maximum admissible temperature is ca. 100° C. In case of higher temperatures - warning lamp on satellite I illuminated - locate cause and rectify.
Before refilling, allow engine to cool down to below 50° C
For topping up of the cooling system use specially prepared water only. Specially prepared water must consist of: §
calcium-free water, distilled water, rain water
§
anti-freeze compound The mixing ratio of anti-freeze / cooling water must be at least 50 % : 50 % (anti-freeze protection down to -40 °C).
§
For use at lower temperatures, the amount of anti-freeze must be increased accordingly.
Ü After filling in cooling liquid allow the engine to run for short period to eliminate air voids before topping up with cooling liquid to the lower edge of the filler tube. Fig. 3-18:
Radiators
Ü In case of significant cooling-liquid losses, the whole cooling system must be checked for leaks.
The radiator (1, Fig. 1) is located on the superstructure.
Check regularly:
Ü After each working shift: examine radiator fins for dirt and clean, if required.
3-42
Ü all lines for leaks and all hose clamps for tightness.
