b.Clean the battery before storing. A dirty bat- tery will lose its charge over time.

c.Store the battery with a full charge. A dis- charged battery will freeze (refer to the table below).

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 factory 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 bat- tery.

c.Attach the end of the black jumper cable to the Negative terminal of the charged battery.

d.Attach the other end of the black jumper cable to the frame of the unit with the low charge battery.

6.Fuses: There are two fuses located in the wiring between the ignition and start switch and other electrical components. This is a standard plug-in

type automotive fuse rated at 20 amp for the main harness and 10 amp for the digital fuel injector and fuel pump.

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 steering lever/park brake switche and (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 following operational checks should be made daily.

a.Blade Clutch Switch: Sit in the operator’s seat. With both steering levers 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 electric 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 collection sys- tems used, and dusty/dirty conditions), and the air-gap adjusted if more than 0.025". To inspect, remove the “negative” cable from the battery and all sparkplug 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 inspection slots in the brake cover. To adjust, successively tighten each of the three gap adjustment nuts an equal amount. Insert a feeler gage (see page 25 for specs) into each slot as the air gap adjustment nut are tightened. The correct adjustment occurs when slight contact with the feeler gage occurs. Engage the BBC (PTO Clutch) a cou- ple of times, and re-check the air-gap. If it is not between the specs listed on page 25, repeat the adjustment procedure.

b.Steering lever/Parking Brake Switch: Sit in the operator’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
