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 battery and ignition start switch.
This is a standard plug-in type automotive
fuse rated at 20 amp.
7. Safety Switches: There are three safety
switches in the electrical circuit which control
the engine. They are (1) the blade clutch
switch, (2) the parking brake/lap bar switch,
(3) the seat switch.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 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 can be moved. 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 in the neu-
tral 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 100 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 0.025". 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 (PTO Clutch). The air-gap should be
adjusted to 0.012" to 0.015". There are
three inspection slots in the brake cover. To
adjust, successively tighten each of the
three gap adjustment nuts an equal
amount. Insert a feeler gage (0.012" to
0.015") into each slot as the air gap adjust-
ment nut are tightened. The correct adjust-
ment occurs when slight contact with the
feeler gage occurs. Engage the BBC (PTO
Clutch) a couple of times, and re-check the
air-gap. If it is not between 0.012" and
0.015", repeat the adjustment procedure.
b. Parking Brake Switch: Sit in the opera-
tor's seat. With both steering levers in the
neutral position and the blade clutch switch
"off", release the parking brake and try to
start the engine. The engine should not
start. If it does, the parking brake switch
must be repositioned or perhaps replaced.
If the engine does not start, engage the
parking brake and start the engine. Swing
one steering lever up to the operating posi-
tion and the engine should stop. If the
engine does not stop, the parking brake
switch must be repositioned or replaced.
c. Seat Switch: With both steering levers
opened-out to the neutral position, the
parking brake engaged and the blade
clutch switch in the "off" position, start the
engine. Now release the parking brake,
hold down on the back of the operator's
seat against spring pressure, and swing
one of the steering levers up to the operat-
ing position. Release the operator's seat
and the engine should stop. If the engine
does not stop, the seat switch must be
replaced. With both steering levers folded
out in the neutral position, the parking
brake engaged and the blade clutch switch
in the "off" position, sit in the operator's
seat and start the engine. Turn the blade
clutch switch to the "on" position and the
blades should start to rotate. Raise up
slightly off the operator's seat and the
blades should stop. If the blades do not
