Changing the Engine 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.

Remove the key.

3. Place a pan below the oil drain. Remove the oil drain

cap (Fig. 38).

4. When oil has drained completely, install the drain cap.

Note: Dispose of the used oil at a certified recycling

center.

page 30, into the filler tube (Fig. 37). Now check the

oil level; refer to Checking the Engine Oil Level, page

30. 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 the

Engine Oil, page 31.

2. Remove the old filter and wipe the filter adapter

gasket surface (Fig. 39).

3. Pour new oil of the proper type in through the center

hole. Stop pouring when the oil reaches the bottom of

the threads. Allow a minute or two for the oil to be

absorbed by filter material.

4. Apply a thin coat of new oil to the rubber gasket on

the replacement filter (Fig. 39).
