up. Fill with new oil until oil reaches bottom
of threads. Allow 2 minutes for oil to be
absorbed by fi lter material.
4. Apply a thin fi lm of clean oil to rubber gasket
on new fi lter.

Fuel Recommendations
WARNING
Explosive Fuel can cause fi res
and severe burns.
Do not fi ll fuel tank while engine
is hot or running.
Gasoline is extremely fl ammable and
its vapors can explode if ignited. Store
gasoline only in approved containers, in
well ventilated, unoccupied buildings, away
from sparks or fl ames. Spilled fuel could
ignite if it comes in contact with hot parts or
sparks from ignition. Never use gasoline as a
cleaning agent.
NOTE: Any fuel grades above E85
are NOT
approved and should NOT be used;
eff ects of old, stale or contaminated
fuel are not warrantable.
NOTE: When switching fuel grades, fi ll up on
partial tank; run engine for at least 20
minutes under normal use, for system
to learn new fuel.
NOTE: If switching fuel grades with an empty
fuel tank, expect a couple of 20 minute
run sessions for system to fully learn
new fuel; performance may be reduced
while engine adapts to change in
ethanol concentration.
Fuel must meet these requirements:
● Clean, fresh, unleaded gasoline; fuel grades
from E0 to E85.
● Octane rating of 87 (R+M)/2 or higher.
● Research Octane Number (RON) 90 octane
minimum.
● Methyl Tertiary Butyl Ether (MTBE) and
unleaded gasoline blend (max 30% MTBE by
volume) are approved.
● Do not add oil to gasoline.
● Do not overfi ll fuel tank.
● Do not use gasoline older than 30 days.
Fuel Line
High pressure fuel line meeting SAE R9 or R12
standard, with high ethanol compatibility, must
be installed on Kohler Co. engines equipped
with an EFI system.
Spark Plugs
CAUTION
Electrical Shock can cause injury.
Do not touch wires while engine
is running.
Clean out spark plug recess. Remove plug and
replace.
1. Check gap using wire feeler gauge. Adjust
gap, see specifi cation table for adjustment.
2. Reinstall plug into cylinder head.
3. Torque plug to 20 ft. lb. (27 N·m).
Jump Starting
Follow all safety guidelines and procedures
provided by battery manufacturer and/or
original equipment manufacturer (OEM). Failure
to follow proper procedures may result in
serious personal injury and/or non-warrantable
damage to engine’s EFI components.
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) may illuminate if electrical
problems or faults are detected. Servicing by a
Kohler authorized dealer is necessary.
