3.5ENGINE AIR CLEANER

Paper Filter: Once every 25 operating hours or once each year (whichever comes first), clean or replace the paper filter (Figure 3.3). Follow the steps on page 12.

3.7ENGINE SPARK PLUG

Clean engine spark plug and set gap to 0.030 inch (0.76mm) every 100 hours of operation (Figure 3.5). Clean by scraping or wire brushing and washing with commercial solvent. DO NOT BLAST CLEAN SPARK PLUG.

•Remove air cleaner cover, then remove paper filter.

•Clean air filter by gently tapping it on a solid sur- face. If the filter is too dirty, replace it with a new one. Dispose of the old filter properly.

•Clean air cleaner cover then insert new paper filter into cover and assemble to the base of the air cleaner.

Sparking can occur if wire terminal does not

!fit firmly over spark plug terminal end. If nec- essary, reform wire terminal to obtain a tight fit.

3.8INVERTER

All repairs of the inverter must be handled by an authorized service dealer (see Figure 3.7).

3.9 CLEANING THE GENERATOR

Keep the generator set as clean and dry as possible. Dirt and moisture that are permitted to accumulate on electrical windings have an adverse affect on the insulation resistance of those windings.

Moisture that is allowed to remain in contact with windings will be retained in voids and cracks of the windings. Dirt makes the problem worse, since it tends to hold the moisture into contact with the windings. Salt, as from sea air, worsens the problem since it tends to absorb moisture from the air. The combination of salt and moisture makes a good elec- trical conductor.
