c. Store the battery with a full charge. A dis-
charged battery will freeze (refer to the
table below).
d. Recharge battery when ever the specific
gravity value is less than 1.225
3. Battery Removal
Warning:
When removing the cables from the battery
follow these steps to avoid a short between
the wrench and the frame.
a. Remove the Negative (black) cable.
b. Remove the Positive (red) cable.
c. Release the hold down straps.
d. Remove the battery without tipping.
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
battery.
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.

Fuses:
There are two fuses located in the wir-
ing between the ignition and start switch and
other electrical components. This is a stan
-
dard plug-in type automotive fuse rated at 20
amp for the main harness and 10 amp for the
digital fuel injector and fuel pump.

Safety Switches:
There are five 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
and (5) 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
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.

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 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). See page 24 for air gap
adjustment specs. There are three inspec
-
tion slots in the brake cover. To adjust, suc-
cessively tighten each of the three gap
adjustment nuts an equal amount. Insert a
feeler gage (see page 24 for specs) into
