Changing the Engine Oil
1. Start the engine and let it run for 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 ensure that the oil
drains completely.
3. Disengage the PTO, set the parking brake, lower the
attachment lift, stop the engine, and remove the
ignition key.
