8. Remove the drain plug and seal
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

Every 100 hours/Yearly (whichever comes first)
Change the oil twice as often during special
operating conditions; refer to
Machine under Special Operating Conditions

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
Note:
Do not use a damaged or worn spark
plug. Replace it with a new spark plug of the
specified type.
1. Side electrode
2. Center electrode insulator
5. Set the air gap between the center and side
of the electrodes at 0.762 mm (0.030 inch) as
shown in Figure
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.
