IMPORTANT TIPS FOR CARE OF THE KOHLER
ENGINE
Fuel System
● Fuel must be clean - free from water, dirt, and
organic material.
● Change fuel lter on a regular basis and when
contamination is suspected or found in the fuel.
● The fuel injection system is pressurized. Do not
attempt to service this fuel system. Contact your
Walker dealer or authorized Kohler service dealer
for work on the fuel system.
Starting/Stopping
● Start engine with the throttle advanced off idle
(1/4 to 1/2 throttle). This will aid starting, especially
in cold weather.
● Keep the battery fully charged.
● Match crankcase oil viscosity to the ambient
tem perature, allowing the engine to crank faster and
start easier.
● Allow engine to run at idle for a few seconds
be fore stopping engine to avoid run-on or backring.
Cooling System
CAUTION
If a pressure washer is used on the ex-
posed working parts, avoid water on the
electrical parts and the engine cooling
system.
● Fill the cooling system with a pre-mixed solu-
tion of 50/50 antifreeze (ethylene glycol) and dis-
tilled water.
IMPORTANT: Solution must be pre-mixed before
putting it in the engine (adding pure antifreeze into
the radiator may cause damage to the engine by
causing overheating).
● Maintain proper uid levels in the radiator and
overow tank.
● Operate the engine at full speed when mowing.
This will allow the engine to produce full horsepower
and move more cooling air through the radiator.
Air Cleaner System
● Use only Donaldson air cleaner elements.
After market elements may not seal in the air cleaner
housing, allowing dirt to enter the engine. Also, af-
termarket lters often skimp on the ltration media
and require more frequent replace ment (see follow-
ing instructions).
● Use the air lter restriction gauge to indicate the
need to service the air lter.
● Do frequently check the Turbine Precleaner for
free movement of the internal fan.
● DO NOT overservice or frequently “disturb” the
air lter. A dirty air lter actually cleans better than
a new one. Changing and cleaning the air lter too
often can actually reduce lter efciency and in-
crease the opportunity for traces of dust to enter the
engine. Wait until the element really needs servicing
as indicated by the air lter restriction gauge.
● When the air lter element is removed or re-
placed, make sure all dust is cleaned out of the air
cleaner housing and hose. Use a damp cloth and
wipe the interior of the canister and hose clean (a
lit tle dirt left here will be sucked into the engine and
reduce engine life). When the lter is reinstalled,
make sure the element is held tight and straight
in the canister for proper seating and sealing.
● Periodically check the air intake hose for cuts,
nicks, etc., and the hose clamps for tightness.
Oil
● Use only multi-viscosity oils as specied with
the viscosity matching ambient temperatures for the
en gine operating conditions. This will aid starting
in cold weather and assure proper lubrication in hot
weather.
● Use only Kohler oil lters. Aftermarket lters
may not seal properly and/or have the incorrect
pressure relief valve for proper lubrication.
