OPERATING INSTRUCTIONS RH 40 F Inspection and servicing COOLING SYSTEM 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. 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 / 212° F. In case of higher temperatures warning lamp on satellite illuminated - locate cause and rectify.
If the cooling-liquid level is too low, a warning lamp on a satellite in the control column lights up. The cap (2) of the expansion reservoir is accessible from above. Risk of scalding from hot cooling liquid. Open radiator cap cautiously.
" Turn radiator cap (2) back to the first notch. " 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. Before refilling, allow engine to cool down to below 50° C / 122° F
For topping up of the cooling system use specially prepared cooling liquid CAT ELC, Terex|O&K Part No. 2482777 only. This gives an anti-freeze protection down to -37 °C / -34.6°F. For use at lower temperatures, ask the Terex|O&K Service or your CAT-dealer. Fig. 3-18:
Radiators and cooling liquid The radiator (1, Fig. 3-18:) is located on the superstructure. " After each working shift: examine radiator fins for dirt and clean, if required.
After filling in cooling liquid allow the engines to run for short period to eliminate air voids before topping up with cooling liquid to the lower edge of the filler tube. " Remove hose from express coupling. The express coupling closes automatically. " Screw on protective cap. " In case of significant cooling-liquid losses, the whole cooling system must be checked for leaks. Check regularly: " all lines for leaks and all hose clamps for tightness.
