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 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. 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. Use either a flat screw
driver, 3/8 inch or 10 mm wrench to open valve
(Fig. 38).
4. Rotate valve end clockwise to close valve. Rotate
valve end counterclockwise to open valve (Fig. 38).
5. When oil has drained completely, close the drain valve
(Fig. 38).
Note: Dispose of the used oil at a certified recycling
center.

6. Slowly pour approximately 80% of the specified oil,
on page 36, into the filler cap (Fig. 37). Now check the
oil level; refer to Checking Oil Level, page 36. Slowly
add additional oil to bring it to the full mark.
Change the 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 37.
2. Remove the old filter and wipe the filter adapter
(Fig. 39) gasket surface.
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).

5. Install the replacement oil filter to the filter adapter.
Turn the oil filter clockwise until the rubber gasket
contacts the filter adapter, then tighten the filter an
additional 1/2 turn (Fig. 39).
6. Fill the crankcase with the proper type of new oil;
refer to Engine Oil on page 36.
Servicing the Spark Plug
Check the spark plug(s) after every 200 operating hours.
m–5624
Make sure the air gap between the center and side
electrodes is correct before installing the spark plug. Use a
spark plug wrench for removing and installing the spark
plug(s) and a gapping tool/feeler gauge to check and
adjust the air gap. Install a new spark plug(s) if necessary.
Type: Champion Premium Gold 2071 (or equivalent) Air
Gap: 0.030 inch (0.76 mm)
Removing the Spark Plug
1. Disengage the power take off (PTO) and turn the
ignition key to off. Move levers to neutral locked
position and apply parking brake. Remove the key.
2. Pull the wire(s) off the spark plug(s) (Fig. 40). Now
clean around the spark plug(s) to prevent dirt from
falling into the engine and potentially causing damage.
3. Remove the spark plug(s) and metal washer.
