the power take-off. When first starting to use hydraulic functions, use the
predefined factory setting M2 to set the maximum flow to 50% for the first few

Starting with an auxiliary battery

You can start the engine with an auxiliary battery (jump starting).
IMPORTANT: Never use jump leads that are damaged or otherwise inadequate.
Use only well protected heavy-duty jump leads with strong clamps.
IMPORTANT: Never try to start the engine by short-circuiting leads.
1. Check that the auxiliary battery has the same voltage as the standard
battery.
2. Connect the jump lead between the (+) terminal on the auxiliary battery and
the (+) terminal on the tractor battery.
3. Connect another jump lead between the (-) terminal on the auxiliary battery
and the (-) terminal on the tractor battery.
4. Start the engine.
5. When the engine has started, disconnect the jump leads in the following
order:
• Remove the jump lead between the (-) terminals.
• Remove the jump lead between the (+) terminals.
WARNING: A fully charged battery connected directly to a dead
battery can cause a current surge capable of causing the batteries to
explode.
WARNING: Make sure that the jump leads are properly connected
to the terminals. Otherwise the jump leads can cause a short
circuit, which might lead to the explosion of the battery.
