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 six positive
cable connections, 2, before c leaning. 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.
