STEERING WITH THE JOYSTICK CONTROL The machine will travel in the direction the lever is moved. When the lever is released, it will return to the neutral, center position. Use caution when turning the machine, as the machine can turn sharply if the joystick steering lever is used abruptly. When executing a turn, move the lever gradually in the direction of the desired turn. Steering can be returned instantly to standard steering if the steering wheel is moved from its stationary position.

Before moving the machine in any reverse direction, you must confirm that the area is clear of personnel and/or other objects and equipment. Failure to comply could result in machine damage, serious injury or death. CE-NA000

Reverse Right: With the transmission in reverse, move the lever gradually to the right for a right reverse turn. An abrupt movement to the right reverse will cause the machine to turn sharply to the right. Be sure to move the lever in a careful, gradual shift. Reverse Left: With the transmission in reverse, move the lever gradually to the left for a left reverse turn. An abrupt movement to the left reverse will cause the machine to turn sharply to the left. Be sure to move the lever in a careful, gradual shift. The steering speed of the wheel loader is the same in both directions and will increase gradually with the position of the joystick.

WARNING

W170M017

Figure 19

The joystick steering lever moves on an angle of 20° in either direction with a tolerance of ± 5°. This prevents unintentional operation either by erratic movement of the wheel loader or by unintended movement of the driver.

Be cautious when turning with joystick steering. Abrupt movements of the joystick to the left or right could cause the machine to turn more sharply than acceptable. Take necessary precautions. Do not use the joystick for primary steering. It is intended for short repetitive operations. Failure to comply could result in machine damage, death or serious injury. M1336

The lift arm and bucket control lever will operate as it would with conventional steering. Practice with the joystick steering in a clear area unobstructed by people and other equipment.

1. F-N-R SWITCH

A. Forward B. Neutral C. Reverse An F-N-R (forward-neutral-reverse) switch is located on the left arm rest as a convenience feature when using the joystick steering option. The features and functions of the switch are identical to the standard F-N-R switch. This FNR switch is only active when the joystick steering has been activated. To actuate the armrest F-N-R switch the following conditions MUST be met:

Figure 21

BS10C001

2. KICK DOWN SWITCH

The kick down switch is used to shift down through the gears in single steps. Each time the switch is pressed, the transmission will shift down one gear range until first gear is reached. Once the kick down switch has been pressed down, the transmission maximum gear allowed is lowered. It will return to the automatic mode when the transmission control lever gear changes, or the transmission control lever is moved to NEUTRAL and then to FORWARD or to REVERSE. When the Automatic Mode has been chosen by the operator, the Automatic Mode indicator will be shown in the multi-function display.

1. The machine must be stopped. 2. The engine must be running. 3. The armrest F-N-R switch must be in neutral. 4. The standard transmission control lever must be in neutral. 5. The parking brake must be released. NOTICE: The gearshift lever located on the steering column always has priority.

WARNING Do not use joystick steering if operating at speeds over 20 km/h (12.4 mph). This limit depends on the actual ground conditions in which it operates. Always use the primary steering wheel at higher speeds for optimum control of the machine. Failure to comply could result in machine damage, death or serious injury. M1349
