nance Instruction Manual for the
engine.
Risk of injury from rotating or hot en-
gine components.
Shut off the engine and wait for it to
cool down.
Do repair work only if the machine is
secured as described under "Se-

Carefully read personal and machine SAFETY INSTRUCTIONS (at the beginning of this manual)
SAFETY INSTRUCTIONS
Assisted starting (with jumper cables), safety
instructions
EXPLOSION HAZARD
Battery gases contain hydrogen and
are highly flammable. Keep potential
ignition sources such as unshielded
lights or lighted cigarettes away from
the batteries.
Risk of injury from acid splashes and
battery gases.
Never lean over the batteries when
starting the machine from another
vehicle.
Wear goggles.
Never use assisted starting if the bat-
teries are defective or frozen.
Never connect batteries (battery as-
semblies) unless they have the same
voltage.
Use only tested jumper cables with
insulated terminal clips and an ade-
quate lead diameter.
Ensure that the bodies of the sup-
plying and receiving machines are
not in contact. Otherwise a current
flow could result from connecting
the positive poles. Risk of short-
circuiting.
Never use assisted starting involving
overvoltage, e.g. two or three bat-
teries connected in series or auxil-
iary devices generating higher
voltages than 12V.
Never use welding generators or
welding transformers as a source of
current.
Position the jumper cables in such a
way that they cannot be caught by
rotating engine components.
Read and observe: "Inspection and
Servicing, Safety Instructions",
paying special attention to the sec-
tion "Handling batteries".
