3.3.6 REPLACING THE SPARK PLUG

Use spark plug F6TC, NGK BP6IS or Champioin RN11YC. Replace the plug once each year. 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 13).

Maintenance

3.4 SERVICE AIR FILTER

The engine will not run properly and may be damaged if using a dirty air filter. Clean the air filter every 25 hours (Figure 15). Clean or replace more often if operating under dusty conditions.

•Remove air filter cover.

•Wash in soapy water. Squeeze filter dry in clean cloth (DO NOT TWIST).

•Clean air filter cover before re-installing it.

and clean the screen at least once each year (Figure 14). If unit is used regularly, inspect and clean more often.

NOTICE:

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:

•Remove clamp and spark arrestor from muffler.

•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.

•Replace the spark arrestor and clamp.

3.5 VALVE CLEARANCE

•Intake — 0.10 ± 0.02mm (cold), (0.004" ± 0.0008" inches)

•Exhaust — 0.15 ± 0.02mm (cold) (0.006" ± 0.0008" inches)

After the first 50 hours of operation, check the valve clearance in the engine and adjust if necessary.

Important: If feeling uncomfortable about doing this procedure or the proper tools are not available, please take the generator to the nearest service center to have the valve clearance adjusted. This is a very important step to ensure longest life for the engine.

3.6 GENERAL

The generator should be started at least once every seven days and be allowed to run at least 30 minutes. If this cannot be done and the unit must be stored for more than 30 days, use the following information as a guide to prepare it for storage.

NEVER store engine with fuel in tank indoors or in enclosed, poorly ventilated areas where fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer or other gas appliance.
