Section 3 – Maintenance

5.Wrap the foam precleaner in a clean cloth and gently squeeze it dry.

6.Saturate the foam precleaner in clean engine oil. Gently squeeze it in a clean cloth to remove excess oil and to distribute oil (DO NOT TWIST).

7.Install the foam precleaner into the cover, fol- lowed by the paper filter.

8.Install the cover, foam precleaner and paper fil- ter.

9.Tighten the two screws to retain the filter in place.

‹3.3.2 CLEANING OR REPLACING THE PAPER FILTER

Once each year or every 100 hours of operation (whichever comes first), clean or replace the paper filter. The new replacement filter must be flame retardant. Service the paper filter more frequently if operating the generator in extremely dusty or dirty conditions. Use the following procedure (Figure 3.2):

1.Follow steps 1-3 in the "Cleaning the Foam Precleaner" section; service the foam precleaner if necessary.

2.Remove the paper filter.

3.Clean the air 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.

4.Clean the air cleaner cover then reassemble following steps 7-9 in the "Cleaning the Foam Precleaner" section.

3.4CLEAN AIR INTAKE

Clean all foreign material from the air intake (Figure 3.3) at least once every 100 hours of operation. Clean more often if necessary.

Inspect the area around the generator exhaust muf- fler periodically and remove all grass, leaves, dirt, etc., from this area.

3.5CHECKING THE ENGINE

SPARK PLUG

Clean the spark plug and reset the spark plug gap every 100 hours of operation.

1.Clean the area around the base of the spark plug to keep dirt and debris out of the engine. Clean by scraping or washing using a wire brush and commercial solvent. Do not blast the spark plug to clean.

2.Remove the spark plug and check the condition. Replace the spark plug if worn or if reuse is ques- tionable.

3.Check the spark plug gap using a wire feeler gauge. Adjust the gap to 0.030 inch (0.76 mm) by carefully bending the ground electrode (Figure 3.4).

Sparking can occur if the wire terminal does not fit firmly on the spark plug terminal end. If nec- essary, re-form the wire terminal to obtain a tight fit.
