Checking the Oil Level
1. Park the machine on a level surface.
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. Do not run engine
with oil below the low mark 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 the used oil at a certified recycling center.
