3.2.1Enter or leave the cab Climb up Caution!

Entering or leaving the cab incorrectly could lead to injury.

Proceed with the same attention on exit or entry of the cab, as while climbing the machine.

Ensure that the safety lever is always in its highest position when entering or leaving the cab.

Always use the handholds provided for the purpose when entering or leaving the machine.

Face the machine when getting in or out and always use three-point support, i.e. two hands and one foot or two feet and one hand must always be in contact with the access system at the same time.

Never use the control elements as handles. Never jump from the machine.

Getting in

If the access ladder is in its lowest position and the excavator is not running, you can climb up on the machine.

Climb in with the ladder and with your face towards the ladders and use the provided handholds.

On the cabin catwalk, open the door.

Go in the cabin and take place on the operator seat. Adjust the seat if necessary.

Getting out

Switch to off the machine and push the safety lever up. Open the door fully.

Go out of the cabin on the cabin catwalk. Close the door.

Go down with your face towards the ladders, and use the appropriate handholds.

Access ladder

The access ladder can be moved into:

Control and operation

The access and the outfit of the cab

Before operating the excavator, the access ladder must be fully lifted to the uppercarriage and locked in upper position.

The access ladder can be automatically extended and retracted from the uppercarriage with the control box E1022, which is located on the catwalk near the cab door.

Danger!

Never actuate the 45° access ladder if you or a third person are on the ladder or in immediate proximity of the ladder.

Move the ladder into lower position

If the principal batteries are connected, you can move the access ladder in lower position with the electric motor on or off.

Push the button S158 to extend the ladder until it is at the lowest position.

Move the ladder into upper position (working position)

Make sure that the electric motor is running.

Push the button S155 until the ladder is at the top position (working position). When the ladder gets its top position, it is locked and warning light H67 goes off.

Caution!

For safety reason, the excavator can only be operated if the ladder is locked in its top position. This means that the swing and travel movements remain locked.

This safety measure can be momentarily by-passed by pushing and holding the but-
