3. Shut off the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Wait for the engine and hydraulic system to cool for
10 minutes.
Note: The oil level on the dipstick is incorrect if you
check the oil when the machine is hot.
5. Move the seat forward.
