REPLACING SPARK PLUGS
Refer to Table 4 for scheduled spark plug replace-
ment. (The genset has two spark plugs, Figure 14.)
The spark plugs must be in good condition for
proper engine starting and performance. A spark
plug that fouls frequently or has heavy soot deposits
indicates the need for engine service. See Trouble-
shooting (Page 22).
To prevent cross threading, always thread a spark
plug in by hand until it seats and then torque to
10 lbs-ft (13 N-m).
