Safety Rules
Leaving the machine
1. When leaving the machine, ensure that it will
not roll away (apply parking brake, chock
blocks). Shut off the engine, remove the main
switch key (ignition key) and lock the operator’s
cab (if installed)! – Turn off the battery isolating
switch!
2. Never leave the machine unattended as long as
the engine is still running!
3. Lower the front attachments to the ground
before leaving the combine-harvester.
Compressor-type air conditioner
1. The air conditioning system is filled with HFC
refrigerant R 134 A. HFC refrigerants must not
be vented to the atmosphere! – Therefore,
please take appropriate precautions when
working on the compressor-type air conditioner.
2. Maintenance and repairs are only to be carried
out by competent, professional service centres
qualified to handle refrigerants. Refrigerants
must always be discharged by use of the
correct recovery equipment and disposed of for
recycling.
Maintenance
1. Repair, service and cleaning work and the
elimination of malfunctions should only be
performed with the drive and the tractor engine
switched off – remove the ignition key!
2. Escaping fluid (fuel or hydraulic oil) under high
pressure can penetrate the skin and cause
serious injury. In such a case, consult a doctor
immediately as otherwise serious infections
may result!
3. Always turn off the battery isolating switch
before carrying out any electrical repairs on the
machine.
4. Be careful when opening the radiator cap.
The radiator is under pressure when the engine
is hot!
5. Dispose of oil, fuel and filters in a way that is
harmless to the environment and in accordance
with existing anti-pollution regulations!
6. Do not attempt to mount a tyre unless you have
the proper equipment and experience to
perform the job safely.
7. Retighten the wheel nuts and wheel bolts
regularly!
8. Only have qualified workshops carry out repair
work on the hydraulic system!
9. Always turn off the battery isolating switch
before carrying out any maintenance work on
the machine and on the engine.
Basic rule
Always check the operating and road safety of the
machine before using it.
Pressure accumulator
Be especially careful when working on the pressure
accumulators! Pressure accumulators are under
high pressure!
With valve-controlled pressure accumulators – as
for example on the CLAAS Autopilot – first slacken
the short-circuit bolt before carrying out any repair
work at the pressure accumulator. This is necessary
to dump the hydraulic pressure.
