Starting
Actuating the preheating system too long can damage the preheater.

After you have completed the starting preparations:
☞ Insert the starting key in the starter
☞ Turn the starting key to position “1”
☞ Check whether all indicator lights illuminate.
☞ Turn the starting key to position “2” and hold it in this position until indicator light 3-6
goes out.
➥ The intake air is preheated
☞ Turn the starting key to position “3” and hold it in this position until the engine starts
➥ If the engine does not start after 10 seconds, interrupt the start procedure and try
again after about 1 minute
➥ If the engine still does not start after the second try, contact a Wacker Neuson
service center for troubleshooting.
➥ As soon as the engine runs:
☞Release the starting key
In order to avoid damage to the engine and the exhaust turbocharger due to
insufficient lube oil supply, handle the engine as follows as you start it:
☞ Do not run the cold engine at full throttle.
☞ Let the engine warm up at low idling speed (for about 30 seconds).
☞ Do not stop the engine from full throttle.
☞ Let the engine run at idling speed for about 2 minutes.
☞ When the engine runs smoothly, check that indicator lights 31 and 29 have
gone out.
☞ Replace malfunctioning indicator lights immediately.
In general, a battery delivers less energy in cold conditions. Therefore ensure that
the battery is always well charged
The engine will possibly not start if High Flow is switched on!
