IMPORTANT TIPS FOR CARE OF THE KOHLER

ENGINE - MODEL MBK

Fuel System

• Fuel must be clean - free from water, dirt, and organic material.

• Change fuel filter on a regular basis and when contamination is suspected or found in the fuel.

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 temperature, 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 backfiring.

Cooling System

  CAUTION

DO NOT use a pressure washer to clean the cooling system on an air-cooled engine, mud may form under the cooling shroud on the cylinder head and cooling fan.

• Keep engine air intake screen and cylinder head fins free of grass clippings, chaff, and dirt. Inspect intake screen and cooling fins for cleanliness and no damage.

• Periodically remove two access panels in the engine shroud to inspect and clean cylinder head cool ing fins.

• Check performance of the cooling system by starting the engine, holding a hand adjacent to the cylinder head, and feeling the cooling airflow.

  DANGER

Make sure to keep hands clear of exhaust pipe, muffler, and moving parts when checking airflow.

KOHLER TIPS

• Operate the engine at full speed when mowing.

This allows the engine to produce full horsepower and move more cooling air through the engine cool ing fins.

Air Cleaner System

• Use only Cummins/Fleetguard air cleaner elements. Aftermarket elements may not seal in the air cleaner housing, allowing dirt to enter the engine.

Also, aftermarket filters often skimp on the filtration media and require more frequent replacement (see following instructions).

• Use the air flow restriction gauge to indicate the need to service the air filter.

DO NOT overservice or frequently “disturb” the

air filter. A dirty air filter actually cleans better than a new one. Changing the air filter too often can ac tually reduce filter efficiency and increase the oppor tunity for traces of dust to enter the engine. Wait until the element really needs servicing as indicated by the air flow restriction gauge.

• When the air filter 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 filter 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 specified with the viscosity matching ambient temperatures for the engine operating conditions. This will aid starting in cold weather and assure proper lubrication in hot weather.

• Use only Kohler oil filters. Aftermarket filters may not seal properly and/or have the incorrect pressure relief valve for proper lubrication.
