4. Maintenance 9-2010
Always:
1. Keep the battery case and terminals clean and dry and the terminals tight.
2. Remove battery cables with a battery terminal puller. Torque threaded stud battery
terminals as recommended by the battery manufacturer.
3. Make sure which terminal is positive (+) and which is negative (-) before making battery
connections, always removing the negative (-) cable first and reconnecting it last to reduce
arcing.
NOTE: If the battery needs to be replaced, be sure that the replacement battery
specs match those found in the Specifications Table in this manual.
4.7 Spark Plugs
WARNING: Before working on the generator set, move the Switch (S2) to the Stop
Position, disconnect the remote harness (P7) to disable the ATS mounted
charger, and remove the negative (-) battery cable from the battery to prevent
starting.
Set the genset control to the Off position before checking the spark plugs.
Refer to the Periodic Maintenance Table for scheduled spark plug replacement.
The genset has two spark plugs: one on each side of the engine. 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.
To prevent cross threading a spark plug, always thread it in by hand until it seats. Torque the
spark plug to 15 lb-ft (20 N-m).
Return the genset control to Auto when finished performing maintenance.
