Fuel Recommendations
Explosive Fuel can cause fi res
and severe burns.
If a gaseous odor is detected,
ventilate area and contact an
authorized service technician.
Propane is extremely fl ammable and is
heavier than air and tends to settle in low
areas where a spark or fl ame could ignite
gas. Do not start or operate this engine in
a poorly ventilated area where leaking gas
could accumulate and endanger safety of
persons in area.
To ensure personal safety, installation and
repair of propane fuel supply systems must
be performed only by qualifi ed propane
system technicians. Improperly installed and
maintained propane equipment could cause
fuel supply system or other components to
malfunction, causing gas leaks.
Observe federal, state and local laws
governing propane fuel, storage, and
systems.
This engine is certifi ed to operate on
commercial propane (per GPA STD 2140). If
you have any questions, contact your propane
supplier.
This engine requires propane fuel in a gaseous/
vapor source from a supply tank designed for
use with gaseous/vapor draw.
Propane from an appropriate propane fuel tank
(supplied separately) is required to operate this
engine.
Vaporizer/Regulator
In compliance with government emission
standards, vaporizer/regulator is preset
at factory to provide proper supply of fuel.
No adjustment or resetting of vaporizer/
regulator is to be made. All service relating to
vaporizer/regulator must be performed by a
Kohler authorized dealer or qualifi ed propane
personnel only.
Vaporizer/regulator can change propane from
supply tank to a gaseous/vapor state.
Lock-Off assembly opens and closes controlling
fuel fl ow from supply tank before reaching
vaporizer/regulator.
Over time, fuel deposits can accumulate inside
vaporizer/regulator. Removing these deposits
is recommended. Follow steps below to drain
vaporizer/regulators.
1. Turn fuel supply valve off , run engine out of
fuel, and turn off ignition switch.
2. Disconnect and ground spark plug leads.

gap, see specifi cation table for adjustment.
2. Install plug into cylinder head.
3. Torque plug to 20 ft. lb. (27 N·m).
Electronic Fuel Injection (EFI) System
EFI is an electronically-controlled fuel
management system which is monitored by an
Electronic Control Unit (ECU). A Malfunction
Indicator Light (MIL) will illuminate if problems
or faults are detected. Servicing by a Kohler
authorized dealer is necessary.
Fuel System Components
Engines are equipped with special EFI fuel
fi lters. See Maintenance Schedule.
