4.8

Actuating the emergency
stop switch

Danger

Danger of accident!

In events of emergency and in case of danger
actuate the emergency stop switch immediate-
ly.

Start travel operation of the machine only after
the danger that caused the actuation of the
emergency stop switch has been eliminated.

Caution

Do not use as service brake. The deceleration
is extremely high. In case of frequent use the
wear on the multi-discs brakes will be very
high.

Note

The machine is equipped with three emergency
stop switches.

Fig. 91

Press the button of the emergency stop switch
(Fig. 91) completely down, it automatically
locks in fully pressed position.

Note

Shuts the engine down and closes the brake.

Turn the button clockwise to unlock the emer-
gency stop switch.

Start the engine again, see chapter "Starting
the engine".

4.9

Emergency exit

Fig. 92

If the machine has turned over and the cabin
door is jammed, the central rear cabin window
(Fig. 92) can be used as emergency exit.
