Maintenance

Servicing the Spark Plug

Service Interval: Every 200 hours/Every 2 years (whichever comes first)

Every 500 hours—Replace the spark plug.

As stated in the maintenance intervals, remove the spark plug, check condition, and reset the gap or replace with a new plug as necessary.

The spark plug is RFI compliant. Equivalent alternate brand plugs can also be used.

Type: Champion XC92YC (for Briggs & Stratton)

Champion RC12YC or QC12C may be used if your area does not require compliance with Canadian ICES-002, ISO 14982, or EN 55012.

Type: Champion RC12YC (for Kohler Command)

Air Gap: 0.030 inch (0.76 mm)

Removing the Spark Plug

1.Disengage the blade control switch, move the motion controls outward to the park position, stop the engine, and remove the key.

2.Pull the wire off of the spark plug (Figure 31). Clean around the spark plug to prevent dirt from falling into the engine and potentially causing damage.

Note: Due to the deep recess around the spark plug, blowing out the cavity with compressed air is usually the most effective method for cleaning. The spark plug is most accessible when the blower housing is removed for cleaning.

3.Remove the spark plug and metal washer.

Checking the Spark Plug

1.Look at the center of the spark plug (Figure 32). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty.

Important: Never clean the spark plug. Always replace the spark plug when it has a black coating, worn electrodes, an oily film, or cracks.

2.Check the gap between the center and side electrodes (Figure 32). Bend the side electrode if the gap is not correct.

2.Tighten the spark plug to 15 ft-lb (20 N-m).

3.Push the wire onto the spark plug (Figure 31).

Cleaning the Blower Housing

Service Interval: Every 100 hours/Yearly (whichever comes first) More often under dirty conditions.

To ensure proper cooling, make sure the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times.

1.Remove the blower housing and any other cooling shrouds.

2.Clean the cooling fins and external surfaces as necessary.

3.Make sure the cooling shrouds are reinstalled
