Position 1 = operating voltage. Pilot lamps (1) and (2) light up. z Push the key in and turn further clockwise against spring pressure. Level 2 = no function. Level 3 = start. z release the key as soon as the engine starts up. The pilot lamps will go out. Without cold start aid Before starting, make sure that nobody is standing in the immediate vicinity of the en- gine or work machine. After repair work: Check that all guards have been replaced and that all tools have been removed from the engine. When starting with the flame glow plug/ glow plug/heating flange system do not use any other starting aid (e.g. injection with start pilot). Risk of accident!
If the engine fails to fire and the error lamp lights, the electronic engine control has ac- tivated the start lock to protect the engine. The start lock is released by switching off the system with the ignition key for about 30 seconds. Do not actuate the starter for more than 20 seconds. If the engine does not start up, wait for one minute and then repeat the starting process. If the engine does not start up after two at- tempts, determine the cause as per fault ta- ble ( 61 ). Do not run up the engine immediately to high idling speed / full load operation from cold. Disconnect the engine by uncoupling de- vices to be driven where possible.
