1. Make sure engine oil viscosity is appropriate for
the ambient temperatures. Change oil if there
is a sudden drop in temperature. See ENGINE
OIL RECOMMENDATIONS (Page 1-3).
2. Check the altitude setting (Figure 2-2).
3. Perform spark plug maintenance (Page 3-6).

3. Keep the genset clean.
4. Perform maintenance due. See PERIODIC

5. Check the altitude setting (Figure 2-2).
ALTITUDE ADJUSTMENT
Gasoline Models − For best fuel economy and gen-

tude (Figure 2-2). Look at road maps and road
signs. For the effect of altitude on maximum power,
see LOADING THE GENSET (Page 2-2).
CAUTION
Operating the genset at low altitude
with a high altitude setting can cause power
loss, overheating and engine damage. Always
reset when returning to lower altitudes.
OPERATING IN DUSTY ENVIRONMENTS
Pay particular attention to the following items when
operating the genset in dusty environments:
1. Do not let dirt and debris accumulate inside the
genset compartment. Keep the genset clean.
2. Perform air cleaner maintenance more often
