In case of the optional doublelever, it is possible, if required, by changing from the first steering lever tothe second steering lever (1), to move the left wheel in reverse direction; thisreduces the turning circle in a way that the one-axle host vehicle can turnaround its own axis. The two functions of the steering lever behaveproportionally. This means that the further the second steering lever is pulledthrough, the faster the left wheel turns away from the blocked status in theopposite direction.• If the two first steering levers (2 and 4) are actuated simultaneously, thedrive unit will stop, and it moves in the reverse direction when the secondsteering lever (1 and 5) is actuated simultaneously.• The steering unit with two steering levers on each side is also a safetydevice, because a conscious change of grip is required on the two steeringlevers, to change the direction of turning of the respective wheel.If dangerous situations suddenly occur:• Release the dead man lever (3). The drive connection to the attachment isdisconnected and the wheels are braked. At maximum speed the machinecomes to a standstill after a few metres.6.5 Switching off of combustion engineDANGERDanger to life or risk of injury due to escaping flue gases in confinedspaces!There is danger to life or a risk of injury due to escaping flue gases as well as arisk of property damage on the machine or system!• The engine may not be operated within confined spaces• When starting the engine, do not step in front of the one-axle tractor or theattachment• Do not use starting aid fluids when using an electrical starting aid (startingaid cable)• Generally, provide for sufficient ventilation
