Guardian Technologies 004270-3 Checking the Engine OIL Level, Operation in High Grass or Brush

Section 3 – Maintenance

QUIETPACT™ 75D Recreational Vehicle Generator

◆2.8.4 OPERATION IN HIGH GRASS OR BRUSH

Never operate the generator while the vehicle is parked over high grass, weeds, brush, leaves, or 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.

◆2.8.5 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 reduces insu- lation resistance and will eventually cause problems. Dirt will make the problem worse, since it tends to hold moisture in contact with windings. Salt (as from sea air) will also worsen the problem, since it tends to absorb moisture from the air. Salt and moisture, when combined, form a good electrical conductor.

3.1CHECKING THE ENGINE OIL

LEVEL

After the 25-hour break-in period, check the engine crankcase oil level every eight hours of operation, or at least once daily, before using the generator. For oil capacities and requirements, see “Engine Oil Requirements,” Section 1.5.3. To check the engine oil level, proceed as follows (see Figure 3.1):

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

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

3.Install the dipstick, and fully seat the T-handle; then, remove it again. The oil level should be at the dipstick “Full” mark.

4.If necessary, remove the oil fill plug and slowly add oil until it reaches the dipstick “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 the oil-fill plug and the dipstick before operating the engine.

3.2CHANGING THE ENGINE OIL AND/OR OIL FILTER

Never operate the engine with the oil level

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

Change the engine oil and oil filter after the first 25 hours of operation (after the 25-hour break-in peri- od, see Section 2.8.1). See the “Service Schedule,” Section 3.13, for subsequent oil and filter changes. Change the oil more frequently, if operating consis- tently under heavy load or at high ambient tempera- tures.

To change the oil and/or oil filter, proceed as follows (see Figure 3.1):

1.Run the engine until it is thoroughly warmed up (for at least five minutes) then shut OFF the engine.

2.Immediately after the engine shuts OFF, remove the front service door, located beneath the unit, by retracting the two latches and pivoting the door downward.

3.Remove the air filter (see Section 3.3).

4.Remove the oil-drain plug and drain the oil into a suitable container. Removing the oil-fill plug will allow the crankcase to drain faster.

5.After the oil has drained, replace the oil-drain plug.

Go to step 9 if changing oil only.

6.With the oil drained, remove the old oil filter by turning it counterclockwise.

7.Apply a light coating of clean engine oil to the gas- ket of the new filter.
