Maintenance

To clean or replace paper air filter:

Figure 20 - Spark Arrestor

Remove air cleaner cover; then remove foam pre-filter (service if necessary) and remove paper filter.

Clean paper filter by tapping it gently on a solid surface. If the filter is too dirty, replace it with a new one. Dispose of the old filter properly.

Clean air cleaner cover then slip pre-cleaner over filter. Next insert new

paper filter into the base of the air cleaner. Re-install air cleaner cover.

NOTE:

To order a new air filter, please contact the nearest authorized service center at 1-800-333-1322.

3.6CLEAN SPARK ARRESTOR SCREEN

The engine exhaust muffler has a spark arrestor screen. Inspect and clean the screen at least once each year (Figure 20). 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:

Remove the screen retaining bracket by removing the screw.

Slide the spark arrestor screen out from the tail pipe.

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 screen and the retaining bracket.

3.7ADJUSTING VALVE CLEARANCE

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 insure longest life for the engine.

To check valve clearance:

Make sure the engine is at room temperature (60° - 80° F).

Make sure that the spark plug wire is removed from the spark plug and out of the way.

Remove the four screws attaching the valve cover.

Make sure the piston is at Top Dead Center (TDC) of its compression stroke (both valves closed). To get the piston at TDC, remove the intake screen at the front of the engine to gain access to the flywheel nut. Use a large socket and socket wrench to rotate the nut and hence the engine in a clockwise direction while watching the piston through the spark plug hole. The piston should move up and down. The piston is at TDC when it is up as high as it can go.

Insert a 0.002 - 0.004 inch (0.05 - 0.1mm) feeler gauge between the rocker arm and valve stem. Correct clearance is when a slight drag is felt when sliding the gauge back and forth. If the clearance is either excessively loose or tight the rocker arms will need adjusting.

To adjust valve clearance:

Loosen the rocker jam nut (Figure 21). Use an 10mm allen wrench to turn the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge. Correct clearance is 0.002-0.004 inch (0.05-0.1 mm).

NOTE:

The rocker arm jam nut must be held in place as the pivot ball stud is turned.
