2.10.4 OPERATION IN HIGH GRASS
OR BRUSH
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.

3.1 CHECKING THE ENGINE OIL
LEVEL
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.
3.2 CHANGING 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.
