by Kohler engine Warranty. We would recommend
that you identify the root of the problem and ad­
vise the engine owner of your findings.
The starter bendix drive used by Kohler is de­
signed and manufactured to withstand forces far in
excess of those required for normal operation
when the recommended starter procedures are
followed . Missing or damaged teeth on the bendix
drive gears are not being caused by a defect in
material or workmanshi p . Rather, our testing and
analysis of returned failed starter drives has shown
that bendix drive damage is being caused by en­
gaging the starting motor while the flywheel is in
motion . For this reason, warranty claims for a
failed bendix drive with damaged or missing teeth
will no longer be accepted .
· Overcranking - cranking the starter continuously
for more than the recommended period and/or not
allowing a sufficient cool down period between
starting attempts .
* * Parasitic Load at cranking - a load or force on
the engine at cranking that opposes normal engine
rotation .
Battery Service
A battery is supplied by the equipment manufac­
turer. The battery should be a 1 2 volt unit , rated
at 32 amp hours minimu m .
Battery Test
- I f t h e battery does not have enough
charge to crank the e ngine , recharge it .
NOTE : Do not attempt to jump-start the engine
with another battery. Starting with a battery larger
than recom mended can burn out the starter mo­
tor.
The battery is tested by connecting a DC voltme­
ter across the battery terminals and cranking the
engine. If the battery voltage drops below 9 while
crankin g , the battery is in need of a charge or
replacement .
Battery Charging -
WARNING: Dangerous Acid, Explosive
Gases!
Batteries contain sulfuric acid. T o prevent acid
burns, avoid contact with skin, eyes and clothing.
Batteries produce explosive hydrogen gas while be­
ing charged. Charge the battery only in a well­
ventilated area. Keep cigarettes, sparks, open flame
and other sources of ignition away from the battery
at all times.

T o prevent accidental shorting and the resultant
sparks, remove all jewelry before servicing the
battery.
When disconnecting battery cables, always discon­
nect the negative (--) cable first. When connecting
battery cables, always connect the negative cable
last.
Before disconnecting the negative (
sure all switches are OFF.
spark will occur at the ground terminal. This could
result in an explosion if hydrogen gas or gasoline
vapors are present.
Keep batteries and acid out of the reach of children.
Battery Maintenance
- Regular maintenance will
ensure that the battery will accept and hold a

WARNING: Ignition Coli Overheat!
Always turn the ignition switch OFF or disconnect
the battery cables before charging the battery. Fail­
ure to do this could result in overheating and explo­
sion of the ignition coil.
1 . Check the level of the electrolyte regularly.
distilled
Add water to maintain it at its recom­
mended level .
NOTE : Do not overfill the battery. Poor perform­
ance or early failure will result.
2 . Keep the cables , terminals and external bat­
tery surfaces clean . A buildup of corrosive
acid or dirt on the surfaces can cause the bat­
tery to self-discharg e . Wash the cables, termi­
nals and external surfaces with a baking soda
and water solution . Rinse thoroughly with clean
water.
NOTE : Do not allow the baking soda solution to
enter the battery cells . The solution will chemically
destroy the electrolyte.
