6. 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 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 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. Use either a flat screw
driver, 3/8 inch wrench, or 10 mm wrench to open the
valve (Fig. 32).
4. Rotate the valve end clockwise to close the valve.
Rotate the valve end counterclockwise to open the valve
(Fig. 32).
5. When the oil has drained completely, close the drain
valve (Fig. 32).
Note: Dispose of the used oil at a certified recycling center.

the filler cap (Fig. 31). Refer to Servicing the Engine
Oil, page 29.
7. Check the oil level; refer to Checking the Oil Level,
page 29.
8. Slowly add additional oil to bring it to the full mark.
Changing the Oil Filter
Replace the oil filter every 200 hours or every other oil
change.
Note: Change the oil filter more frequently when operating
conditions are extremely dusty or sandy.
1. Drain the oil from the engine; refer to Changing the Oil,
page 30.
2. Remove the old filter (Fig. 33).
3. Apply a thin coat of new oil to the rubber gasket on the
replacement filter (Fig. 33).
