other electrical components. This is a stan-
dard plug-in type automotive fuse rated at 7.5 
amp.

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.

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 300 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-
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.

c.

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.

d.

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
