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.
Hazardous voltage. Moving parts.
Will cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
areinplace.
DANGER
Air Cleaner. Check for a clean and installed air cleaner
element to prevent unfiltered air from entering engine.
Air Inlets. Check for clean and unobstructed air inlets.
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) according to the drive belt system
maintenance information.
Enclosure Doors, if equipped. Check that the service
access doors are closed and secured. Leaving the
doors open will create excessive noise.
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 keep the tank(s)
full to ensure adequate fuel supply.
Controller Check. Touch the controller screen to verify
that it turns on. The controller screen dims automatically
after a period of time with no activity.
Oil Level. Maintain the oil level at or near, not over, the
full mark on the dipstick.
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.
Radiator. Check that the radiator fins and air
inlets/outlets are clean of leaves, insects, dirt, and other
debris. Use compressed air to clear the obstructed
passages as needed.
Visual Inspection. Walk around the generator set and
look for leaking fluids, loose or dangling wiring, and
loose or missing hardware. Repair as needed before
starting the generator set. This visual inspection should
be routinely done while the unit is running.
