Clean the Battery Connections
The battery connections must be cleaned and tightened
to maintain proper operation of the electrical system
of the tractor.
Remove the three battery ground cable connections,
(1) first, and then the three positive cable connections,
(2) before cleaning. Each connection has a rubber
boot covering it for protection. The connections are
loosened by turning the nut counterclockwise and
pulling the connection from the battery mounting
stud.
Clean the battery stud, battery cable and mounting
nut thoroughly with a brush and reinstall the cables.
Attach the positive cables first and the ground cables
last.
CAUTION: WHEN SERVICING THE BATTERIES,
DISCONNECT THE NEGATIVE (BLACK) CABLES
BEFORE THE POSITIVE (RED) CABLES. WHEN
CONNECTING THE CABLES, CONNECT THE
POSITIVE CABLE FIRST, THEN THE NEGATIVE. THIS
WILL REDUCE THE POSSIBILITY OF SPARKING
AND BATTERY EXPLOSION.
WARNING: ALL BATTERIES GENERATE HYDROGEN
GAS, WHICH IS HIGHLY FLAMMABLE. IF
IGNITED BY A SPARK OR FLAME, THE GAS MAY
EXPLODE VIOLENTLY CAUSING A SPRAY OF ACID,
FRAGMENTATION OF THE BATTERY, AND POSSIBLE
SEVERE PERSONAL INJURY, PARTICULARLY TO
THE EYES.
THEREFORE, AS A SAFETY PRECAUTION:
• WEAR PROTECTIVE CLOTHING AND GOGGLES.
• DO NOT SMOKE OR EXPOSE THE BATTERY TO
OPEN FLAME.
• DO NOT CONNECT OR DISCONNECT LIVE
CIRCUITS.
If the batteries require removal, disconnect the cables
as previously detailed. Loosen the wing nuts (3) and
lower the clamps (4) downward. Lift the battery to be
removed from the battery tray.
