MAINTENANCE

Ignition System

The engine is equipped with an electronic ignition system. Only the spark plugs require maintenance.

1.For recommended spark plugs, see Technical Data.

2.Remove the ignition cable boot and clean around the spark plug.

3.Remove the spark plug with a spark plug socket wrench.

4.Check the spark plug. Replace the spark plug if fouled, the electrodes are burned or if the insulation is cracked or damaged. Clean the spark plug with a steel brush if it is to be reused.

5.Measure the electrode gap with a gapping tool. The gap should be .030" (0.75 mm). Adjust as necessary by bending the side electrode.

6.Reinsert the spark plug, turning by hand to avoid damaging the threads.

7.After the spark plug is seated, tighten it using a spark plug wrench so that the washer is compressed. A used spark plug should be turned 1/8 of a turn from the seated position. A new spark plug should be turned a ¼ turn from the seated position.

8.Reconnect the ignition cable.

Safety System

The machine is equipped with a safety system that prevents starting under the following conditions.

The engine can only be started when:

1.the blades are disengaged.

2.the speed control is in the start position.

Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met.

If the machine starts when one of these conditions is not met, turn the machine off and repair the safety system before using the machine again.

Function Check

Check the function of the safety electrical system on a regular basis.

1.Engine must stop if blades are engaged without operator presence levers held down.

2.Engine must stop if the speed control is taken out of the start position without holding down operator presence levers.

3.Engine must not start unless blades are off and the speed control is in the start position.

IMPORTANT INFORMATION

Fitting the wrong spark plug type can damage the engine.

Inadequately tightened spark plugs can cause overheating and damage the engine. Tightening the spark plugs too hard can damage the threads in the cylinder head.
