Tipping up the operator's cab
For details see 5.1.1 “Tipping up the operator's cab” (5-3).
Two people for maintenance work when the engine is run-
ning
In order to avoid injury, do not carry out maintenance while the
engine is running. If maintenance must be carried out while the
engine is running, the work must be carried out by at least two
workers, observing the following.

One worker must always sit in the operator's seat and be
ready to stop the engine at any time. The workers must
always maintain contact with each other.

When working near the fan, fan belt or other rotating parts,
there is a risk of being caught in the device. Ensure that you
do not go too close to them.

Never allow tools or other items to fall into the fan or onto the
fan belt or stick tools or other items into other rotating parts.
There is a risk that they will come into contact with the rotat-
ing parts and break or be flung back out.

Lower the work equipment to the ground.

Engage the work equipment lock lever.

Do not touch the control lever or steering wheel. If it is nec-
essary to use the control lever or steering wheel, always
give a signal to your colleagues so that they can get into a
safe position.
