QUIETPACT 40G Recreational Vehicle Generator

◆2.10.4 OPERATION IN HIGH GRASS OR BRUSH

3.1CHECKING THE ENGINE OIL LEVEL

Never operate the generator while the vehicle is parked over high grass, weeds, brush, leaves or any other combustible substance. Such materials can ignite and burn from the heat of the exhaust system. The generator exhaust system becomes extremely hot during operation and remains hot for a long time after it has shut down.

◆2.10.5 EFFECTS OF MOISTURE AND DIRT

Keep the generator set as clean and dry as possible. Protect the unit against excessive dust, dirt, corrosive vapors, road splash, etc. Permitting dirt and mois- ture to accumulate on generator windings will have an adverse effect on the insulation resistance of those windings.

When moisture is allowed to remain in contact with windings, some of the moisture will be retained in voids and cracks in the insulation. This causes a reduced insulation resistance and will eventually cause problems. Dirt will make the problem worse, since dirt tends to hold moisture in contact with windings. Salt (as from sea air) also will worsen the problem since it tends to absorb moisture from the air. Salt and moisture, when combined, form a good electrical conductor.

For oil capacities and requirements, see “Engine Oil Requirements,” Section 1.5.4 (Page 6). Check the engine crankcase oil level at least every eight hours of operation, or before you use it. To check the engine oil level, proceed as follows (see Figure 3.1):

1.Be sure the generator is as level as possible.

2.Remove the dipstick and wipe it dry with a clean, lint-free cloth.

3.Install and tighten the dipstick cap; then, remove it again. The oil level should be at the dipstick “Full” mark.

4.If necessary, remove the oil fill cap on the rocker cover and slowly add oil until it reaches the dip- stick “Full” mark. DO NOT FILL ABOVE THE “FULL” MARK.

Never operate the engine with the oil level

!below the “Add” mark on the dipstick. Doing this could damage the engine.

5.Install and tighten the oil fill cap and the dipstick before operating the engine.

3.2CHANGING THE ENGINE OIL

AND/OR OIL FILTER

•Change the engine oil after the first 25 hours of operation (after the 25-hour break-in period, see Section 2.10.1, Page 10). Thereafter, change the oil every 100 operating hours. Change the oil more frequently if operating consistently under heavy load or at high ambient temperatures.
