d.Recharge battery when ever the specific gravity value is less than 1.225
4.Installing the Battery
Note: The battery is delivered from the fac- tory fully charged and filled with electrolyte.
a.Attach the positive (red) cable.
b.Attach the negative (black) cable.
c.Attach the rubber battery strap.
5.Jump Starting
Warning:
Failure to use this starting procedure can cause sparking, and the gases in the battery to explode.
a.Attach the end of the red jumper cable to the positive terminal (+) of the charged bat- tery.
b.Attach the other end of the red jumper cable to the positive terminal (+) of the low charge battery.
c.Attach the end of the black jumper cable to the negative terminal of the charged bat- tery.
d.Attach the other end of the black jumper cable to the frame of the unit with the low charge battery.
6.Fuses: There is one fuse located in the wiring between the ignition and start switch and other electrical components. This is a stan- dard plug-in type automotive fuse rated at 7.5 amp.
7.Safety Switches: There are seven safety switches in the electrical circuit which control the engine. They are (1) the blade clutch switch, (2) the parking brake switch, (3) the left and (4) the right steering lever switches,
(5) the seat switch, (6 and 7) the no cut in reverse switches.They operate so that in order to start the engine, the blade clutch switch
must be off, the parking brake must be engaged, and both steering levers must be opened-out to the side in the neutral position. Once the engine is started, the seat must be occupied and the parking brake must be released before either of the steering levers is folded up to the operating position or the engine’s electronic ignition will be grounded out and the engine will stop. Also, the seat must be occupied before the blade clutch switch can cause the blades to rotate.
8.Safety Switch Operation Checks: The fol- lowing operational checks should be made daily.
a.Blade Clutch Switch: Sit in the operator’s seat. With both steering levers opened-out in the neutral position and the parking brake engaged, turn the blade clutch switch “on” and try to start the engine. The engine should not start. If it does, the blade clutch switch must be replaced. If the engine does not start, turn the blade clutch switch “off” and start the engine. Now turn the blade clutch switch “on” and the blades should rotate. If the blades do not turn, the blade clutch switch must be replaced, the seat switch must be replaced or the elec- tric PTO clutch must be repaired. The air- gap should be checked every 200 hrs. (or less, if severe operating conditions exist such as when there are many on/off cycles, mulching operations, material col- lection systems used, and dusty/dirty con- ditions), and the air-gap adjusted if more than 0.035". To inspect, remove the “nega- tive” cable from the battery and all spark- plug wires. The air-gap should be checked with feeler gages in the three slots of the BBC. The air-gap should be adjusted to 0.013" to 0.015". There are three inspec- tion slots I the brake cover. To adjust, suc- cessively tighten each of the three gap adjustment nuts an equal amount. Insert a feeler gage (0.013" to 0.015") into each slot as the air gap adjustment nut are tight- ened. The correct adjustment occurs when slight contact with the feeler gage occurs. Engage the BBC a couple of times, and re- check the air-gap. If it is not between 0.013" and 0.015", repeat the adjustment procedure.
b.Parking Brake Switch: Sit in the opera- tor’s seat. With both steering levers opened-out in the neutral position and the blade clutch switch “off”, release the park- ing brake and try to start the engine. The engine should not start. If it does, the park-
