Battery Charging

WARNING:

Explosive

Gas!

Batteries produce explosive hydrogen gas while being

charged. To prevent a fire or explosion, charge

batteries only in well ventilated areas. Keep sparks,

open flames, and other sources of ignition away from

the battery at all times. Keep batteries out of the reach

of children. Remove all jewelry

when servicing

batteries.

Before disconnecting

the negative (-) ground cable,

make sure all switches are OFF: If ON, a spark will

occur at the ground cable terminal which could cause

an explosion if hydrogen gas or gasoline vapors are

present.

On engines equipped

with an alternator charging

system, disconnect

plug from rectifier-regula for prior to

charging battery.

Fuel Filter

Some engines are equipped with an in-line fuel filter.

Periodically

inspect the filter and replace when dirty.

Use a genuine Kohler filter.

Reduction Gear Units

On engines equipped with a reduction gear unit,

remove the oil plug on lower part of cover every

50 hours of operation to check oil level. With the

engine level, the oil level of the unit should be up to

the bottom of the oil plug hole. To add oil, remove the

vented plug at the top of theunit.

Use the same

weight and grade of oil as used in the engine

crankcase.

Carburetor Troubleshooting

and Adjustments

NOTE:

Carburetor

adjustments

should be made only

after the engine has warmed up.

Kohler K241 through K341 engines are equipped with

one of two basic types of carburetors

- Kohler or

Walbro - fixed main jet or adjustable

main jet.

The carburetor

is designed to deliver the correct

fuel-to-air

mixture to the engine under all operating

conditions.

The main fuel and idle fuel needles on

adjustable jet carburetors

are set at the factory and

normally do not require further adjustment.

On fixed

jet carburetors,

the low idle fuel needle is also set at

the factory and normally does not need further

adjustment.

The main fuel jet is calibrated

and

installed at the factory and is not adjustable*.

*NOTE:

K241 through K341 engines with fixed jet

carburetors,

operating

at altitudes above

approximately

6000 ft., may require a special

"high altitude" main jet. See your Kohler

Engine Service Dealer for further information.

Troubleshooting

If engine troubles are experienced

that appear to be

fuel system related, check the following

areas before

adjusting the carburetor.

Make sure the fuel tank is filled with clean, fresh

gasoline.

Make sure the fuel tank cap vent is not blocked

and that it is operating

properly.

If the fuel tank is equipped with a shutoff valve,

make sure it is open.

If the engine is equipped with an in-line fuel filter,

make sure it is clean and unobstructed.

Replace

the filter if necessary.
