8. Remove the drain plug and seal ( Figure 36 ).
Note:
Allow the oil to completely drain from the
engine.
9. Install the drain plug and seal, and torque the
drain plug to 17.6 N∙m (13 ft-lb).
10. Pour oil into the fill opening until the oil level is
up to the Full mark on the dipstick.
Note:
Do not overfill the engine with oil.
11. Install the oil-fill cap and dipstick firmly in place.
12. Connect the battery and lower the cargo bed.
Changing the Engine-Oil Filter
Service Interval: After the first 25 hours
Every 100 hours/Yearly (whichever comes first)
Change the oil twice as often during special
operating conditions; refer to
Maintaining the
Machine under Special Operating Conditions
(page 27)
.
1. Drain the oil from the engine.
2. Remove the existing oil filter ( Figure 36 ).
3. Apply a light coat of clean oil to the gasket of
the new oil filter.
4. Thread the new filter onto the filter adapter until
the gasket contacts the mounting plate, then
tighten the filter an additional 1/2 to 3/4 turn
(
Figure 36 ).
Important:
Do not overtighten the oil filter.
5. Fill the crankcase with the specified oil ( Figure
34 ).
6. Start and run the engine to check for oil leaks.
7. Shut off the engine and check the engine-oil
level.
Note:
If necessary, add the specified oil into
the engine until the oil level is at the Full mark
on the dipstick.
Servicing the Spark Plugs
Service Interval: Every 100 hours/Yearly (whichever
comes first) Replace the spark plug
if necessary.
Type: Champion RN14YC (or equivalent)
Air Gap: 0.03 inch (0.762 mm)
Important:
A cracked, fouled, dirty, or
malfunctioning spark plug must be replaced. Do
not sand-blast, scrape, or clean electrodes by
using a wire brush because grit may eventually
release from the plug and fall into the cylinder.
The result is usually a damaged engine.
Note:
The plug should be removed and checked
whenever the engine malfunctions.
1. Clean the area around the spark plug so that
foreign matter cannot fall into the cylinder when
you remove the spark plug.
2. Pull the wire off the terminal of the spark plug.
3. Remove the plug from the cylinder head.
4. Check the condition of the side electrode, center
electrode, and center electrode insulator to
ensure that there is no damage (
Figure 37 ).
Note:
Do not use a damaged or worn spark
plug. Replace it with a new spark plug of the
specified type.

5. Set the air gap between the center and side
of the electrodes at 0.762 mm (0.030 inch) as
shown in
Figure 37 .
6. Install the spark plug into the cylinder head, and
torque the plug to 20 N∙m (14.7 ft-lb).
7. Install the spark-plug wire.
8. Repeat steps 1 through 7 for the other spark
plug.
