5. Screw the oil dipstick fully onto the fill hole.
Unscrew the dipstick, pull it out, and look at
the metal end. If the oil level is low, slowly
pour only enough oil into the fill hole to raise
the level to, but not over, the Full mark on the
dipstick.
Important: Do not overfill the crankcase
with oil because the engine may be
damaged.

Changing the Oil

1. Start the engine and let it run until warm. 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 blade control switch 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.
Components under the hood will be
hot if the machine has been running. If
you touch hot components you may be
burned.
Allow the machine to cool before
performing maintenance or touching
components under the hood.
5. Place a pan below the drain pipe. Remove the
cap on the drain pipe and allow oil to drain
(Figure 26).

6. When oil has drained completely, replace the
drain pipe cap.
Note: Dispose of the used oil at a recycling
center.
7. Change the oil filter, if necessary (Figure 27).
8. Clean around the oil dipstick and unscrew the
cap (Figure 24).
9. Slowly pour approximately 80% of the
specified oil into the filler tube (Figure 24).
10. Check the oil level; refer to Checking the Oil
Level in Engine Maintenance, page 21.
11. Slowly add additional oil to bring it to the full
mark.

Changing the Oil Filter

Replace the oil filter every 100 hours or every
other oil change.
Note: Change the oil filter more often in dusty,
dirty conditions.
1. Drain the oil from the engine; refer to Changing
and Draining the Oil in Engine Maintenance,
page 21.
2. Remove the old filter and wipe the filter
adapter gasket surface (Figure 27).
3. Apply a thin coat of clean oil to the rubber
gasket on the replacement filter (Figure 27).
