Battery Charging
A
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.
l
Make sure the fuel tank cap vent is not blocked
and that it is operating
properly.
l
If the fuel tank is equipped with a shutoff valve,
make sure it is open.
l
If the engine is equipped with an in-line fuel filter,
make sure it is clean and unobstructed.
Replace
the filter if necessary.
