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.
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.
Exhaust System. Check for exhaust leaks and
blockages. Check the muffler 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 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.
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.
