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.
Air Shrouding.
Check for securely installed and
positioned air shrouding.
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 Belt(s). Check the belt condition and tension of
the water pump and battery charging alternator belt(s).
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 for cracks and
corrosion (exhaust manifold, exhaust line, exhaust
clamps, and muffler).
Check for corroded or broken metal parts and replace
D
them as needed.
Check for loose, corroded, or missing clamps and
D
hangers. Tighten or replace the exhaust clamps
and/or hangers as needed.
Check that the exhaust outlet is unobstructed.
D
Check the exhaust gas color. If the exhaust is blue or
D
black, contact your local distributor/dealer.

indicates an exhaust leak. Seal leaks as needed.
Ensure that the carbon monoxide detector is (1) in the
D
vehicle, (2) functional, and (3) energized whenever
the generator set operates.
For your safety: Never operate the generator set
without
monoxide detector(s) for your
safety and the safety of others.
Fuel Level. Check the fuel level and keep the tank(s)
full to ensure adequate fuel supply.
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.

2.3 Load Profile
Whenever operating the generator set, Kohler Co.
recommends maintaining the minimum load profile
indicated in Figure 2-2. Maintaining the load profile
prevents corrosion formation on internal engine
components when they're exposed to the breakdown of
exhaust gases.
