3.4.6 REPLACING THE SPARK PLUG

Use spark plug F6TC. Replace the plug every 100 hours of

operation. This will help the engine start easier and run better.

1. Stop the engine and pull the spark plug wire off of the spark

plug.

2. Clean the area around the spark plug and remove it from the

cylinder head.

3. Set the spark plug's gap to 0.76 mm (0.030 in.). Install the

correctly gapped spark plug into the cylinder head and torque

to 15 ft/lbs. (Figure 15).

3.4.7 SPARK ARRESTOR

The engine exhaust muffler has a spark arrestor screen. Inspect

and clean the screen at least once each year (Figure 16). If unit is

used regularly, inspect and clean more often.

NOTE:

If using the generator on any forest-covered, brush-covered

or grass-covered unimproved land, it must equipped with a

spark arrestor. The spark arrestor must be maintained in good

condition by the owner/operator.

Clean and inspect the spark arrestor as follows:

1. Remove clamp and spark arrestor from muffler.

2. Inspect screen and replace if torn, perforated or otherwise

damaged. DO NOT USE a defective screen. If screen is not

damaged, clean it with commercial solvent.

3. Replace the spark arrestor and clamp.
