Checking Oil Level
1. Park the machine on a level surface, disengage the
power take off (PTO) and turn the ignition key to
"OFF" to stop the engine. Remove the key.
2. Clean around the oil dipstick (Fig. 38) so dirt cannot
fall into the filler hole and damage the engine.
3. Unscrew the oil dipstick and wipe the end clean
(Fig. 38).
4. Slide the oil dipstick fully into the filler tube, do not
thread onto tube (Fig. 38). Pull the dipstick out and
look at the end. If 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/Draining 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. Then disengage the power take off (PTO),
set the parking brake, and turn the ignition key to
"OFF" to stop the engine. Remove the key.
3. Place a pan below the oil drain. Use either a flat screw
driver, 3/8 wrench or 10mm wrench to open valve
(Fig. 39).
4. Rotate valve end clockwise to close valve. Rotate
valve end counterclockwise to open valve (Fig. 39).
5. When oil has drained completely, close the drain valve
(Fig. 39).
Note: Dispose of the used oil at a certified recycling
center.

6. Slowly pour approximately 80% of the specified
amount of oil, page 30, into the filler tube (Fig. 38).
Now check the oil level; refer to Checking Oil Level,
page 31. Slowly add additional oil to bring to "FULL"
mark on dipstick.
Change Oil Filter
Replace the oil filter every 200 hours or every other oil
change.
Note: Change oil filter more frequently when operating
conditions are extremely dusty or sandy.
1. Drain the oil from the engine; refer to
Changing/Draining Oil, page 31.
2. Remove the old filter (Fig. 40).
3. Apply a thin coat of new oil to the rubber gasket on
the replacement filter (Fig. 40).

4. Install the replacement oil filter to the adapter. Turn
the oil filter clockwise until the rubber gasket contacts
the filter adapter, then tighten the filter an additional
3/4 turn (Fig. 40).
5. Fill the crankcase with the proper type of new oil;
refer to Changing/Draining Oil, page 30.
