Carefully read personal and machine SAFETY INSTRUCTIONS (at the beginning of this manual)

SECURING THE MACHINE
Work on the working equipment
should only be carried out if the ma-
chine has been secured as described
in the chapter "Securing the ma-
chine".

SELECTING THE WORKING
EQUIPMENT
The machine can be fitted with a va-
riety of working equipment. The
working equipment components are
assembled with hydraulic cylinders
and connectors. The components
can be combined in a variety of ways
so that the working equipment can
be best adapted to the specific task.

Operate the machine only with equip-
ment and component combinations
approved by the Manufacturer for
this machine.

Install and commission equipment
and component combinations only
after the Manufacturer has checked
the proposal and given its approval
in writing.

Attachments from other manufac-
turers subject to the EC Machine Di-
rective 89/392 EEC may be mounted
and put into operation only if:
- the manufacturer’s declaration of

conformity, 

- the declaration of compatibility

from CNH are at hand.

SECURING THE MACHINE

Secure the machine as described below:
• Before carrying out any servicing or repair work

on the machine.

• Before fitting or changing the working equipment.
• Park the machine on level, firm ground.
• Set working equipment down on the ground.
• Apply parking brake.

• Turn off engine.
• Remove key from the key switch in the electrical

system.

• Depressurize the hydraulic system.
• Lock the pivot joint.
• Secure open hood.
• Secure the machine from rolling away by placing

chocks under the wheels.

• Switch off battery main switch and remove

switching lever.

• Disconnect batteries before work on the electrical

system or before welding work.

• When doing welding jobs on the machine, observe

"Repair work - Welding operations”.

RISK OF INJURY
The machine must not be started by
unauthorised persons.
Therefore, secure the machine.

Never shut off the engine out of full
load, but continue running for ca.
three minutes at idling speed to cool
down.
