Driving on slopes

DANGER Danger of accident Uphill • Driving on a slope is dangerous because the vehicle can tip over if the centre of gravity exceeds the tipping limit • Use the vehicle only if slipping, crashing or falling over is out of the question

The following factors reduce the risk: Figure_183 – proper loading – low centre of gravity – low driving speed – no climbing – proper tyre pressure depending on the load – large track width

ADVICE The driving comfort and traction of the vehicle can be increased by reducing the tyre pressure. We recommend the type of driving described in the figure for turning on a slope.

ADVICE Adjusting volume flow 0 to 25 l/min If the master switch (13) is switched off, the hydraulic functions are 14 14 blocked. This prevents an inadvertent actuation of hydraulic switches or the joystick from moving the attachment. Use transport protection when travelling on roads.

C270_079a You can control the volume flow for all hydraulic functions that are operated by buttons jointly using the potentiometer (14). Other than joystick movements; they are proportional. 1. Turning potentiometer (14) to the left throttles the volume low. 2. Turning potentiometer (14) to the right increases the volume flow.

General warnings for operating the hydraulic floating position

DANGER Danger of accident When the floating position is switched on, a lifted implement falls quickly or slowly to the ground, depending on the weight. • Never stand underneath attachments or tipping systems

ADVICE If floating position is switched on, the attachment can be moved by outside influences or move out of the way of obstacles. The attachment is guided on the ground.

Operating the joystick

ADVICE The functions of the attachments that are connected to the front lift or to the hydraulic couplings at the front or the rear are controlled with the joystick. The couplings are colour-marked, i.e., an identical colour corresponds to an identical assignment.

DANGER Danger of accident • Because of the variety of attachments and connection possibilities, check functions by a test run before use • Carry out the test run at a secure location

ADVICE The joystick can be moved down (forward) and up (backward), as well as to the right and the left. Additional functions can be activated by pressing various keys
