318 Engine Problems when tilting the cab Engine Starting and stopping the engine with the cab tilted Breakdown assistance G WARNING Certain components in the engine compart- ment could be very hot, e.g. the engine, the radiator and parts of the exhaust system. There is a risk of injury when accessing the engine compartment. As far as possible, allow the engine to cool down and only touch the components descri- bed in the following. Before starting and stopping the engine X Turn the key to position 2 in the ignition lock. G WARNING There are moving components in the engine compartment.
Certain components may con- tinue to move or suddenly move again even after the ignition has been switched off, e.g. the radiator fan. There is a risk of injury. If you have to carry out work in the engine compartment: X Tilt the cab forwards ( Y page 314). X Shift into neutral. Starting the engine X Press external engine start/engine stop : until the engine starts. Starting the engine and increasing the engine speed R never touch the dangerous areas surround- ing moving components, e.g. the rotation area of the fan R switch off the ignition X Hold down external engine start/engine stop : until the desired engine speed is achieved. After about three seconds, the engine speed increases.
After external engine start/engine stop : has been released, the engine continues to run at the speed currently set. The engine speed can be increased up to the limiting speed. R remove jewellery and watches R keep items of clothing and hair, for exam- ple, away from moving parts. Be aware of the road and traffic situation when working on public roads and secure the parking spot accordingly. Problem Possible causes/consequences and M Solutions The cab cannot be til- ted. The hydraulic pump valve lever is in the "tilt back" position. X Set valve lever on hydraulic pump to the "tilt forwards" position (Y page 314). The tilting hydraulics are leaking or have failed.
