Important: Do not overfill the crankcase
with oil and run the engine; engine damage
can 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.
3. Disengage the PTO and set the parking brake.
4. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
5. Slide the drain hose over the oil drain valve.
6. Place a pan below the drain hose. Rotate oil
drain valve to allow oil to drain (Figure 37).
7. When oil has drained completely, close the
drain valve.
8. Remove the drain hose (Figure 37).
Note: Dispose of the used oil at a recycling
center.

oil; refer to Servicing the Engine Oil.
