OPERATING IN COLD WEATHER
Make sure the engine oil viscosity is appropriate for
the cold weather temperatures. See ENGINE OIL
RECOMMENDATIONS (Page 6). Be sure to
change the oil if a sudden drop in temperature oc-
curs.
OPERATING IN HOT WEATHER
Pay particular attention to the following items when
operating the genset in hot weather:
1. Make sure nothing blocks airflow to and from
the genset.
2. Make sure engine oil viscosity is appropriate for
the ambient temperatures. See ENGINE OIL
RECOMMENDATIONS (Page 6).
3. Keep the genset clean.
4. Perform maintenance due. See PERIODIC
MAINTENANCE SCHEDULE (Page 13).
OPERATING AT HIGH ALTITUDE
For the effect of altitude on maximum power, see
LOADING THE GENSET (Page 9).
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.
See PERIODIC MAINTENANCE SCHEDULE
(Page 13).
3. Change engine oil more often. See PERIODIC
MAINTENANCE SCHEDULE (Page 13).
4. Keep containers of engine oil that have been
opened tightly closed to keep out dust.
BREAKING IN A NEW ENGINE
Proper engine break-in on a new genset or on one
with a rebuilt engine is essential for top engine per-
formance and acceptable oil consumption. Run the
genset at approximately 1/2 rated power for the first
2 hours and then at 3/4 rated power for 2 more
hours. See LOADING THE GENSET (Page 9).
Proper engine oil and oil level are especially critical
during break-in because of the higher engine tem-
peratures that can be expected. Change the oil if not
appropriate for the ambient temperatures during
break-in. See ENGINE OIL RECOMMENDATIONS
(Page 6). Check oil level twice a day or every
4 hours during the first 24 hours of operation and
change the oil and oil filter after the first 50 hours of
operation.
EXERCISING THE GENSET
Exercise the genset at least 2 hours each month if
use is infrequent. Run the genset at approximately
1/2 rated power. See LOADING THE GENSET
(Page 9). A single two hour exercise period is bet-
ter than several shorter periods.
Exercising a genset drives off moisture, re-lubri-
cates the engine, replaces stale fuel and removes
oxides from electrical contacts. The result is better
starting, more reliable operation and longer engine
life.
