Operation

Load stabilizer (option)

The load stabilizer protects the machine against unstable oscillating movements.

DANGER!

When driving on public roads, the machine may become unstable if the load stabilizer is NOT turned on –

Accident risk.

☞ Always turn on the load stabilizer when driving on public roads.

☞ Follow these instructions

–see Before driving the machine on page48.

IMPORTANT!

Do NOT use the load stabilizer while performing heavy duty work.

Refer to the following table to determine when to use the load stabilizer:

Load stabilizer

Turned off Turned on May be turned on

• In general for heavy-duty work, e.g., picking up excavated material.

Turning on

• For driving on public roads.

• For lighter work with the loader unit.

• For light off-road transport.

☞ Press bottom of rocker switch 65, below A ➥ Indicator in rocker switch comes on.

Turning off

☞ Press top of rocker switch 65, above B ➥ Indicator in rocker switch turns off. Before working with the loader unit:

☞ Turn off the load stabilizer.

IMPORTANT!

The loader unit yields easily with the load stabilizer turned on, making it difficult to carry out any precise lifting movements. The lifting capacity of the loader unit is only about 60% of the rated capacity.

Backup

The backup warning system consists of backup alarm A, fitted onto the inside of the towing device cover, and a switch and wiring. The backup alarm generates an acoustic signal when you shift into reverse. The acoustic level is about 103dB(A) at a distance of 3’ (1 m) and at a frequency of 2800Hz.

WARNING!

When backing up with the machine –Accident risk.

☞ Make sure nobody is within the work area of danger of the machine.

☞ Do not rely exclusively on the backup alarm to alert others.

Differential lock

IMPORTANT!

A differential lock distributes traction evenly to the front and rear wheels. Both the front and rear axles of the machine are fitted with self-locking differentials. The lock value is 45% for each axle. The differential locks automatically and cannot be turned on or off by the operator.

Operation

Steering system

Synchronizing the steering system

WARNING!

DO NOT synchronize the steering system as you drive on public roads –Accident risk.

☞ Synchronize the steering system as described below before driving on public roads.

If the wheels on both axles are not running in the same track:

☞ Drive at a slow speed, turn the steering wheel slowly to the left and right maximum positions twice.

☞ Quickly turn the steering wheel back to the straight-ahead position.

☞ Contact your Mustang dealer if this does not synchronize the wheels.

Synchronizing the steering system (with 25 mph [40 km/h] high speed option)

After starting the machine, synchronize by turning the steering wheel to the left and right. Indicator 39/39 comes on as you turn the wheel. When both steering rams have passed through the straight-ahead position from both directions, synchronization is complete and Indicator 39/39 turns off.

Only the first drive range is active during synchronization. Use rocker switch 39/67 to select the second range, the machine shifts after it finishes synchronizing.

IMPORTANT!

You must synchronize if the wheels no longer follow the same track when driving straight-ahead on level ground.

☞ Proceed as follows:

• Machines with high speed (option): make sure high speed is turned off.

IMPORTANT!

The machine must be at a standstill.

• Select low drive range 67/A –see Forward-reverse control [71] on page56.

• Drive at walking pace on level ground and press tip switch 52/B.

• Steer to the left and right while driving until indicator 39 turns off.

• Complete a functional check of the steering system.

Changing steering mode (withhighspeed option)

Front-wheel steering

The machine actuates front-wheel steering when you shift to high speed (option)

➥ –see Drive range selection on page50.

➥ The machine shifts only after the rear axle is set to straight-ahead. Indicator 48 flashes as the machine shifts.

➥ Indicator 48 for front-wheel steering comes on.

Four-wheel steering

The machine actuates four-wheel steering when you disengage high speed (option)

➥ –see Drive range selection on page50.

➥ The machine shifts after the front axle is set to straight-ahead. Indicator 49 flashes as the machine shifts.

➥ Indicator 49 for four-wheel steering comes on.
