Checking the Oil Level

Note: Check the oil when the engine is cold.

1. and set the parking brake.

2. Stop the engine, remove the key, and wait for all

moving parts to stop before leaving the operating

position.

3. Clean around the oil dipstick (Fig. 44) so dirt cannot

fall into the filler hole and damage the engine.

4. Pull the oil dipstick and wipe the metal end clean.

5. Slide the oil dipstick fully into the filler tube. Pull the

dipstick out and look at the metal end (Fig. 45). If oil

level is low, slowly pour only enough oil into the filler

tube to raise the level to the full mark.

Important Do not overfill the crankcase with oil

because this may cause engine damage. Do not run the

engine with oil below the low mark because the engine

may be damaged as a result.

Changing the Oil

1. Start the engine and let it run five minutes. This warms

the oil so it drains better.

2. Park the machine so that the drain side is slightly

lower than the opposite side to assure the oil drains

completely. Set the parking brake, and turn the ignition

key to off. Remove the key.

3. Place a pan below the oil drain. Remove the oil drain

plug to allow oil to drain (Fig. 46).
