Changing the Engine Oil
Note:
Dispose of the used oil at a recycling center.
1. Start the engine and let it run for 5 minutes.
Note:
This warms the oil so that 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 blade-control switch (PTO) and
engage the parking brake.
