Carbon monoxide detectors. Carbon monoxide can cause severe nausea, fainting, or death. Install carbon monoxide detectors on each level of the building. Locate the detectors to adequately warn the building’s occupants of the presence of carbon monoxide. Keep the detectors operational at all times. Periodically test and replace the carbon monoxide detectors according to the manufacturer’s instructions.

CAUTION

Hazardous noise.

Can cause hearing loss.

Never operate the generator set without a muffler or with a faulty exhaust system.

At the interval specified in the service schedule, inspect the exhaust system components (exhaust manifold, exhaust outlet, exhaust line, exhaust clamps, and muffler) for cracks, leaks, and corrosion.

Exhaust System Inspection Points

DCheck for corroded or broken metal parts and replace them as needed.

DCheck that the exhaust outlet is unobstructed.

DCheck the exhaust gas color. If the exhaust is blue or black, contact your local authorized Kohler distributor/ dealer.

DVisually 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.

DCheck that all covers and doors are undamaged, in place, and locked.

DCheck for the installation and operation of carbon monoxide (CO) detectors on each level of any building near the generator set.

4.6 Cooling System

WARNING

Hot coolant and steam.

Can cause severe injury or death.

Before removing the pressure cap, stop the generator set and allow it to cool. Then loosen the pressure cap to relieve pressure.

Allow the engine to cool. Release pressure from the cooling system before removing the pressure cap. To release pressure, cover the pressure cap with a thick cloth and then slowly turn the cap counterclockwise to the first stop. Remove the cap after pressure has been completely released and the engine has cooled. Check the coolant level at the tank if the generator set has a coolant recovery tank.

4.6.1Checking and Filling Coolant

Maintain the coolant level in the coolant overflow bottle between the Hot and Cold markings. See Section 1, Service Views, for the coolant overflow bottle location.

Note: Periodically check the coolant level by removing the radiator’s pressure cap. Do not rely solely on the level in the coolant overflow bottle.

Ethylene glycol-based long-life coolant is recommended. Use a coolant mixture of 50% long-life coolant and 50% clean, softened water to inhibit rust/corrosion and prevent freezing. Add fresh coolant until the level is just below the overflow tube opening.

A coolant solution of 50% ethylene glycol-based coolant provides freezing protection to --37°C (--34°F) and overheating protection to 149°C (300°F). A coolant solution with less than 50% ethylene glycol may not provide adequate freezing and overheating protection. A coolant solution with more than 50% ethylene glycol can cause engine or component damage. Do not mix long-life coolant and conventional coolants. Do not mix different types and/or colors of long life coolants.
