When cold-starting the engine, turn off all unnecessary equipment that uses
electrical power.
Keep the battery in a warm place when it is not in use.
Starting the tractor under very cold conditions is easier if the battery is kept in
a warm place when it is not in use.
Use the engine heater to ensure a successful start under cold conditions.
Warming up the engine for 2–3 hours before starting is sufficient.
When the engine heater is activated, you can hear a hissing sound.
If you start the engine under very cold conditions, keep the ignition switch in
the starting position until the engine has started.
IMPORTANT: Do not keep the ignition key in the starting position for more
than 60 seconds at a time.
If the temperature is below 0°C, first, warm up the engine and hydraulics oil
for a while at low engine speed.
Allow the engine to run for a few minutes before starting to drive or engaging
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
minutes.
Never race a cold engine.
Run the engine with a light load until it has reached its normal operating
temperature.

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.
WARNING: A fully charged battery connected directly to a dead
battery can cause a current surge capable of causing the batteries to
explode.
