3.3.7Uncoupling the transmission

Danger!

The parking brake no longer functions when the transmission is uncoupled. The machine could roll away if another brake (operating brake) is disabled. When the diesel engine is not running and the transmission is uncoupled, all of the brakes (operating brake, parking brake) on the machine are disabled. The machine could roll away and steering is only possible by applying increased effort.

Make sure that the machine is properly secured to prevent it from rolling away (towing rod and wedges), before uncoupling the transmission.

The machine may only be towed out of the immediate danger area!

A Travel direction 1B Lines

1 Lubrication nipple 2 Bleeder

3 Pressure relief valve

It is possible to release the parking brake and uncouple the transmission by injecting grease into lubrication nipple 1 via line 1B

Use a grease gun to inject grease into lubrication nipple 1 until it exits from pressure relief valve 3

The transmission is hydraulically uncoupled, the parking brake is released. The machine can be towed out of the danger area.

If the diesel engine is running, the machine can be slowed down using the operating brake (foot pedal) and steered with the assistance of the servo steering. If the diesel engine is not running: all brakes on the machine are disabled.

Caution!

The transmission may be damaged if it is used in the uncoupled state. Do not select a gear and do not use the travelling pedal when the transmission has been mechanically uncoupled.

Close the clutch:

Open the emergency controls for bleeder 2

Select the on-road gear. Close bleeder 2 again. The transmission has been coupled up again.

3.3.8Oscillating axle lock

3-43 Oscillating axle lock

Locking the oscillating axle

Turn switch S75 to position 1

The indicator light H311 lights up. The oscillating axle is permanently locked. The stability of the machine is increased.

Turn on the oscillating axle automatic

Danger!

When the automatic oscillating axle lock automatic is turned on (switch S75 in position A), releasing the operating brake will release the oscillating axle lock. This results in a reduction of the stability of the machine and can cause the machine to tip over when a load is lifted and the uppercarriage is turned.

For safety reasons, the oscillating axle cannot be unlocked when the system is overloaded.

If the machine has to be moved with a raised load (e.g. filled bucket, load suspended on safety hook), you must turn off the automatic oscillating axle lock and permanently lock the oscillating axle (switch S75 in position 1) before taking on the load.

Turn switch S75 to position A.

The indicator light H176 lights up.

When the operating brake is applied, the oscillating axle is automatically locked in the current position and is automatically unlocked again when the operating brake is released.

Note!

When working with the excavator, we recommend to lock the oscillating axle. If possible, unlock the oscillating axle before travelling (without a load): Turn switch S75 to position 0

3.3.9Support

Fig. 3-44 Support variations

The machine can be equipped with different support systems:

1 Blade support

2 Blade support, front and rear

3 Outriggers

4 Blade and outrigger support

It is possible to combine the support variations on the front and / or at the rear, depending on installation kit. The outrigger support can be expanded to include the individual control function (option).

3.3.9.1Operating the blade / outrigger support

Fig. 3-45 Operating the blade support

The support is operated using control lever 5

To extend the outriggers or the blade, move the control lever 5 forward a

To retract the outriggers or the blade, move the control lever 5 backward a

If the machines is also equipped with a blade, in addition to the blade / outrigger support, then it must be separately activated with switch S335.

If necessary, press switch S355 down. The blade support is activated. The indicator light in the switch lights up.

To extend the blade, move the control lever 5 forward a

To retract the blade, move control lever 5 backward b

3.3.9.2Individual outrigger control (option)

Fig. 3-46 Individual outrigger control

The selection of the individual outriggers to be used is made via switches S204S207 in the control panel A.

S204 = Outrigger, left front S205 = Outrigger, right front S206 = Outrigger, left rear S207 = Outrigger, right rear

Each outrigger can be controlled individually or together with the other outriggers. Press the corresponding switch

The indicator light in the corresponding switch lights up.

To extend the outrigger(s), move the control lever 5 forward a.

To retract the outrigger(s), move control lever 5 backward b
