Checking the Oil Level
1. Park the machine on a level surface, disengage the
power take off (PTO), stop the engine, and remove the
key.
2. Clean around the oil dipstick (Fig. 31) so that dirt
cannot fall into the filler hole and damage the engine.
3. Unscrew the oil dipstick and wipe the metal end clean
(Fig. 31).
4. Slide the oil dipstick fully into the filler tube. Do not
thread it onto the tube (Fig. 31). Pull the dipstick out
and look at the metal end. If the oil level is low, slowly
pour only enough oil into the filler tube to raise the
level to the full mark.
Important Do not overfill the crankcase with oil
because the engine may be damaged.

Changing the Engine Oil
1. Start the engine and let it run for five minutes. 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. Disengage the power take off (PTO), set the
parking brake, stop the engine, and remove the key.
3. Place a pan below the oil drain. Remove the oil drain
cap (Fig. 32).
4. When the oil has drained completely, install the drain
cap.
Note: Dispose of the used oil at a certified recycling center.

5. Slowly pour approximately 80% of the specified oil,
page 29, into the filler tube (Fig. 31). Now check the oil
level; refer to Checking the Oil Level, page 29. Slowly
add additional oil to bring the level to the full mark on
the dipstick.
