this manual. DO NOT connect the jumper cables to the machine battery terminals. Make sure no
persons are near the connecting points before starting the engine. Start the engine from the operator's
seat.

NOTICE: When using a auxiliary battery to start the en-
gine ensure that the polarity of the jumper cables are cor-
rect POSITIVE to POSITIVE NEGATIVE to NEGATIVE or
the alternator or battery may be damaged.
If you must use jumper cables to start the tractor:
1. Shield your eyes.
2. Connect the red end of the jumper cable to the positive
(+) battery terminal (1) on the tractor and connect the
other red end to the positive (+) battery terminal (2) on
the auxiliary battery.
3. Connect the black end of the jumper cable to the nega-
tive (-) battery terminal (3) on the auxiliary battery then
connect the other black end to a tractor frame ground
or engine ground (4). Finally start the tractor by fol-
lowing the safe starting procedures outlined under See
4-11 .
4. When the engine starts allow the engine to idle and
turn on all electrical equipment (lights etc.) This will
help protect the alternator from possible damage due
to changes in load when disconnecting the jumper ca-
bles.
5. Disconnect the jumper cables in reverse order discon-
nect the black end from the tractor frame or engine
ground (4) then disconnect the other black end from
the negative (-) battery terminal (3) on the auxiliary bat-
tery. Disconnect the red end from the positive (+) bat-
tery terminal (2) on the auxiliary battery then remove
the other red end from the positive (+) battery terminal
(1) on the tractor battery.
