Operating Instructions Also read the operating instructions of the equipment this engine powers. Pre-Start Checklist Starting NOTE: This engine has been shipped without engine oil. Fill with oil, otherwise it will not start. 1. Turn fuel shut-off valve to ‘‘on’’ position. See Figure 6. • Check oil level. Add oil if low. Do not overfill. • Check fuel level. Add fuel if low. • Check cooling air intake areas and external surfaces of engine. Make sure they are clean and unobstructed.
WARNING: Accidental Starts! Disabling engine. Accidental starting can cause severe injury or death. Before working on the engine or equipment, disable the engine as follows: 1) Disconnect the spark plug lead(s). 2) Disconnect negative (-) battery cable from battery.

Warranty repairs must be performed by an authorized Kohler service outlet. WARNING: Accidental Starts! Disabling engine. Accidental starting can cause severe injury or death.
NOTE: Just because you can see oil in the crankcase doesn't mean the level is in the safe range. Bring the level up to the point of overflowing the filler neck. Filler Neck Bring Level Up To Point of Overflow NOTE: If the engine stalls or does not start, turn the engine switch to ‘‘on’’ position and then pull the recoil starter or attempt to start engine.

Reduction Systems 2:1 Reduction Systems All 2:1 reduction systems are lubricated by the crankcase oil of the engine through special openings in the closure plate. No special maintenance or service is necessary. Check and maintain the oil level as outlined on pages 8 and 9. 6:1 Reduction Systems CS4 and CS6: Use an internal pinion and ring gear system, independent of, and separated from the main crankcase lubrication. See Figure 12.
On Heavy Duty Air Cleaner Systems: Remove and clean the lower dirt/swirl chamber. Make sure the openings near the base of chamber and in the air cleaner cover/housing, are not blocked or restricted. See Figure 13. 4. Position the paper element on base and secure with wing nut, then install the precleaner over the element. If element is not secured with a wing nut, place the precleaner over the element and install it as an assembly into the cover/housing.
Check Spark Plug Battery Charging Annually or every 100 hours of operation, remove the spark plug, check condition, and reset the gap or replace with new plug as necessary. The original plug is an NGK BPR4ES. The Champion® equivalent of that NGK plug is RN14YC. The service replacement is Champion® RC14YC (Kohler part No. 66 132 01-S). Equivalent alternate brand plugs can also be used. 1. Before removing the spark plug, clean the area around the base of the plug to keep dirt and debris out of the engine.
Muffler Screen and Spark Arrestor Engines are equipped with a muffler screen and spark arrestor for operational and environmental safety. One of two configurations will be used, determined by the engine model involved. Every 100 hours of operation, remove and clean or replace the muffler screen and/or spark arrestor following the instructions below. Muffler Screen CS4,CS6 CAUTION! The engine and muffler will be very hot after the engine has been run.
Muffler Screen and Spark Arrestor CS8.5,CS10,CS12 CAUTION! The engine and muffler will be very hot after the engine has been run. Avoid touching the engine and muffler while they are still hot, with any part of your body or clothing. 1. Remove the muffler screen. 2. Remove the spark arrestor using a flatblade screwdriver. 3. Clean the carbon deposits out of the muffler screen and spark arrestor using a wire brush.
• Make sure fuel is reaching the carburetor. This includes checking the fuel lines and components for restrictions or problems. Replace as necessary. 2. Low Idle Fuel Needle Setting: Place the throttle into the ‘‘idle’’ or ‘‘slow’’ position. Turn the low idle fuel adjusting needle/cap in or out within adjustment range, to obtain the best low speed performance. • Make sure On-Off switch is functioning properly.
