Section 2 Operation
2.1 Prestart Checklist
To ensure continued satisfactory operation, perform the
following checks or inspections before or at each
startup, as designated, and at the intervals specified in
the service schedule. In addition, some checks require
verification after the unit starts.
Air Cleaner. Check for a clean and installed air cleaner
element to prevent unfiltered air from entering the
engine.
Battery. Check for tight battery connections. Consult
the battery manufacturer’s instructions regarding
battery care and maintenance.
Coolant Level. Check the coolant level according to the
cooling system maintenance information.
Note: Block heater damage. The block heater will fail
if the energized heater element is not immersed
in coolant. Fill the cooling system before turning
on the block heater. Run the engine until it is
warm, and refill the radiator to purge the air from
the system before energizing the block heater.
Drive Belts. Check the belt condition and tension of the
radiator fan, water pump, and battery charging
alternator belt(s).
Exhaust System. Check for exhaust leaks and
blockages. Check the silencer and piping condition and
check for tight exhaust system connections.
Inspect the exhaust system components (exhaust
manifold, exhaust line, flexible exhaust, clamps,
silencer, and outlet pipe) for cracks, leaks, and
corrosion.
D
Check for corroded or broken metal parts and replace
them as needed.
D
Check for loose, corroded, or missing clamps and
hangers. Tighten or replace the exhaust clamps and/
or hangers as needed.
D
Check that the exhaust outlet is unobstructed.
D
Visually inspect for exhaust leaks (blowby) . Check
for carbon or soot residue on exhaust components.
Carbon and soot residue indicates an exhaust leak.
Seal leaks as needed.
Fuel Level. Check the fuel level and fill the tank(s)
regularly to ensure adequate fuel supply.
Ignition System. Ensure that the ends of all spark plug
wires are properly seated onto the coil/distributor and
the spark plug.
Lamp Test. Press the lamp test button, if equipped, to
verify that all controller LEDs illuminate.
Oil Level. Maintain the oil level at or near, not over, the
full mark on the dipstick. Keep the oil level in the
mechanical governor, if equipped, at or near the full
level.
Operating Area. Check for obstructions that could
block the flow of cooling air. Keep the air intake area
clean. Do not leave rags, tools, or debris on or near the
generator set.
2.2 Generator Set Exercising
Operate the generator set under load once each week
for one hour. Perform the exercise in the presence of an
operator if the generator set does not have a
programmed exercise mode or an automatic transfer
switch with an exercise option.
During the exercise period apply a minimum of 35% load
based on the nameplate standby rating, unless
otherwise instructed in the engine operation manual.
The operator should perform all of the prestart checks
before starting the exercise procedure.
Start the
generator set according to the starting procedure in the
controller section of this manual. While the generator
set is operating, listen for a smooth-running engine and
visually inspect the generator set for fluid or exhaust
leaks.

Controller Features
2.3.1 Normal Operation
Local Starting. Move the generator set master switch
to the RUN position to start the generator set at the
controller.
Note: The alarm horn sounds and the Not in Auto lamp
lights when the generator set master switch is not
in the AUTO position.
Note: The transient start/stop function of the 16-light
controller prevents accidental cranking of the
rotating engine.
If the generator set master
switch is momentarily placed in the OFF/RESET
position and then is returned to the RUN position,
the generator set slows to 750 rpm (25 Hz) and
recranks before returning to rated speed.
