Checking the Engine Oil Level
1. Park the machine on a level surface.
2. Disengage the PTO, turn the ignition key to
off, and remove the key.

the operating position and then chock or block
tires.
4. Clean around the oil dipstick (Figure 30) so
that dirt cannot fall into the filler hole and
damage the engine.

clean (Figure 30).
6. Slide the oil dipstick fully into the filler tube,
but do not thread onto tube (Figure 30).

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 31).
7. When oil has drained completely, close the
drain valve.
8. Remove the drain hose (Figure 31).
Note: Dispose of the used oil at a recycling
center.
