Maintenance, Engine Changing the Engine Oil

Maintenance & Adjustments

Maintenance

Warning! Before performing any maintenance or repairs, disengage the PTO, move the drive control levers fully outward in the neutral position, engage the parking brake, stop the engine and remove the key to prevent unintended starting.

Engine

Refer to the Kohler Owner’s Manual for all engine maintenance intervals, procedures, specifications and instructions.

Changing the Engine Oil

Warning! If the engine has been recently run, the engine, muffler and surrounding metal

surfaces will be hot and can cause burns to the skin. Exercise caution to avoid burns.

To complete an oil change, proceed as follows:

1.Run the engine for a short time to warm the engine oil. The oil will flow more freely and carry away more impurities. Use care to avoid burns from hot oil.

2.Locate the oil drain hose on the left side of the engine. Refer to Figure 6-1.

3.Route the free end of the oil drain hose toward an appropriate oil collection container with at least a 2.5 quart capacity, to collect the used oil. Remove the oil fill cap/dipstick from the oil fill tube.

4.While holding the free end of the oil drain hose over the oil collection container, unscrew the square head hose plug from the end of the hose. See Figure 6-1.

Drain the engine oil into the collection container.

5.After draining the oil, wipe any residual oil from the oil drain hose. Thread the square head plug into the drain hose fitting and fully tighten the plug.

6.Replace the oil filter, and refill the engine with new oil as instructed in the Kohler Owner’s Manual.

Air Cleaner

Service the pre-cleaner and cartridge/air cleaner element as instructed in the Kohler Owner’s Manual.

Spark Plug

The spark plugs should be cleaned and the gap reset once a season. Refer to the Kohler Owner’s Manual for correct plug type and gap specifications.

Hydrostatic Transmission

The zero turn tractor is equipped with dual integrated hydrostatic pumps/transaxles that are sealed and are maintenance-free. Fluid levels cannot be checked and fluid cannot be added or changed.
