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
NOTE: Do not apply 12 volt DC to kill terminal of ignition module.
Fuel System
WARNING: Fuel System Under Pressure! The CH26 fuel system operates under high pressure, and the fuel filter and fuel line used must be approved system components only. Use of substitute parts can result in system failure, gasoline leakage and possible explosion.
Fuel Filter
CH26 Engines: A special, high volume, high pressure filter with greater filtration capabilities and internal surface area is used. See Figure 12.
Fuel Filter
Fuel Line
Figure 12. CH26 Fuel Filter and Line.
Replacement is recommended every 1500 hours, or more frequently under extremely dusty or dirty conditions. When replacement is necessary, always use genuine Kohler parts.
Fuel Line
CH26 Engines: A special fuel line capable of withstanding the high pressure of the EFI fuel system is used (must meet SAE R9 specifications). See Figure
12.If fuel line must be replaced, see your Kohler Engine Service Dealer.
