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.
