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.

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 22 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 22 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

couple of times, and re-check the air-gap.

If it is not between the specs listed on page

22, repeat the adjustment procedure.

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-

ing 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 position and the engine

should stop. If the engine does not stop,

the parking brake switch must be reposi-

tioned or replaced.

Left and Right Steering Lever Switches:

Sit in the operator’s seat. With both steer-

ing levers opened-out in the neutral posi-

tion, the parking brake engaged and the

blade clutch switch “off”, swing the left

steering lever up to the operating position

and try to start the engine. The engine

should not start. If it does, the left steering

lever switch must be repositioned or per-

haps replaced. Open the left steering lever

to the neutral position and swing the right

steering lever up to the operating position

and try to start the engine. The engine

should not start. If it does, the right steer-

ing lever switch must be repositioned or

perhaps replaced. If the engine does not

start, Open the right steering lever to the

neutral position and start the engine.

Swing the left steering lever up to the oper-

ating position and the engine should stop.

If the engine does not stop, the left steering

lever switch must be repositioned or

replaced. Open the left steering lever out to

the neutral position and start the engine.

Swing the right steering lever up to the

operating position and the engine should

stop. If the engine does not stop, the right

steering lever switch must be repositioned

or replaced.

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
