Operation
Starting the engine
The ignition lock is located on the right-hand side control lever console.
☞ Apply the parking brake to the last notch
☞ Turn the ignition key (preheating start switch 19) to position “1”
☞ The following telltales must come on
• Engine oil pressure telltale 82
• Telltale 81 if the parking brake is applied
• Alternator charge function telltale 80
• Automatic preheating telltale 85, comes on for about 30 – 60 seconds at normal
temperatures (up to 0°), and for about 60 – 90 seconds at low temperatures
(below 0°)
➥The intake air is preheated via a temperature-dependent time lag relay, and telltale
85 goes out once the temperature is reached
After telltale 85 (automatic preheating) has gone out:
☞ Start the engine as follows:
• Press the accelerator pedal through about 1/4 of its travel
• Turn the ignition key to position “3” and hold it in this position until the engine starts
• Release the ignition key
• Check that the following telltales have gone out:
➥Engine oil pressure telltale 82
➥Alternator charge function telltale 80
➥Cold starter telltale 85
In order to avoid damage to the engine and the exhaust turbocharger due to
insufficient lube oil supply:
☞ Do not run the cold engine at full throttle when starting
☞ Let the engine warm up at low idling speed (for about 30 seconds)
☞ Replace defective telltales immediately
