NOTE: Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or
cooling shrouds removed, will cause engine
damage due to overheating.
Ignition System
This engine is equipped with a dependable electronic
magneto ignition system. Other than periodically
checking/replacing the spark plug, no maintenance,
timing, or adjustments are necessary or possible with
this system.
In the event starting problems should occur which are not
corrected by replacing the spark plugs, see your Kohler
Engine Service Dealer for trouble analysis.
Check Spark Plug
Every 200 hours of operation, remove the spark plug,
check its condition, and reset the gap or replace with a
new plug as necessary. A high-performance spark plug,
®
Champion
Platinum 3071 is standard on PRO Series
engines (Kohler Part No. 25 132 12-S). Some engines
use standard spark plug Champion
Part No. 12 132 02-S). Equivalent alternate brand plugs
can also be used.
1. Before removing the spark plug, clean the area
around the base of the plug to keep dirt and debris
out of the engine.
2. Remove the plug and check its condition. Replace
the plug if worn or reuse is questionable.
NOTE: Do not clean the spark plug in a machine
using abrasive grit. Some grit could remain
in the spark plug and enter the engine
causing extensive wear and damage.
3. Check the gap using a wire feeler gauge. Adjust
the gap by carefully bending the ground electrode.
See Figure 11. Gap plugs to 1.02 mm (0.040 in.).

4. Reinstall the spark plug into the cylinder head.
Torque the spark plug to 24.4-29.8 N·m

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.
Fuel Filter
Most engines are equipped with an in-line fuel filter.
Periodically inspect the filter and replace with a genuine
Kohler filter every 200 operating hours.
Fuel Line
In compliance with CARB Tier III Emission Regulations,
these engines with a Family identification number
beginning with "6" or greater (see Figure 12), must use
Low Permeation SAE 30 R7 rated fuel line; certified to
meet CARB requirements. Standard fuel line may not be
used. Order replacement hose by part number through a
Kohler Engine Service Dealer.
