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 25 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 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.

c.Seat Switch: With both steering levers in the neutral position, the parking brake engaged and the blade clutch switch in the “off” posi- tion, start the engine. Now release the parking brake, hold down on the back of the operator’s seat against spring pressure. 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 in the neutral position, the parking brake engaged and the blade clutch switch in the “off” posi- tion, 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 stop when you dismount from the opera- tor’s seat, the seat switch must be replaced.

d.Electric PTO Clutch: This clutch operates when the engine is running, the operator is in the operator’s seat and the blade clutch switch is turned on.This electric clutch is a fairly trou- ble free device. If a problem develops and the blades do not turn, first check the 20 amp fuse in the yellow, 16-gauge wire between terminal “L” (for the Gasoline Engine) on the ignition switch and the hour meter and then investi- gate the wiring harness and the connections to the seat switch, the blade clutch switch and the electric blade clutch. Then check out the seat switch, the blade clutch switch and finally the electric blade clutch.

E.Tires

The two front wheels are caster wheels that are free to swivel to accommodate the direction of the Mower.

The two rear wheels are used to propel the Mower in the direction of input from the drive handles. Inflation pressure of the rear tires is important for stability while the Mower is in operation. If the tire diameter is not equal between the two tires, the Mower will pull to one side.

1.Inflation Pressure:

a.Traction Tires—20 psi max; 8-10 psi recom- mended

b.Front Caster Wheel—28 psi max; 20-25 psi recommended

c.Cutting Deck Ball Wheels—Solid Polyure- thane.

Use the Following guidelines for maintaining the tires:

a.Balance inflation pressure between the rear tires to help maintain straight travel (see tire side wall for proper inflation pressure).

b.Keep the valve caps tightened to prevent air pressure loss.
