LUBRICATION
1. Engine oil lever check
Check the engine oil level with the engine stopped and in a level position.
1. Remove the filler cap/dipstick and wipe it clean.
2. Insert and remove the dipstick without screwing it into the filler neck.
Check the oil level shown on the dipstick.
3. If the oil level is low, fill to the edge of the oil filler hole with the
recommended oil.
4. Screw in the filler cap/dipstick securely.
2. Engine oil change
Drain the used oil while the engine is warm. Warm oil drains quickly and completely.
1. Place a suitable container below the engine to catch the used oil, and then remove the filler cap/dipstick, drain plug, and
washer.
2. Allow the used oil to drain completely, then reinstall the drain plug, washer, and tighten drain plug securely.
Notice! Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take
used oil in a sealed container to your local recycling center or service station for reclamation. Do not throw it in the
trash; pour it on the ground, or down a drain.
3. With the engine in a level position, fill to the outer edge of the oil filler hole with the recommended oil.
Notice! Running the engine in a low oil level can cause engine damage.
4. Screw in the filler cap/dipstick securely.
SPARK PLUGS
Recommended spark plugs: BPR6ES (NGK). For good performance, the spark plug must be properly gapped and free
of deposits.
Notice! An incorrect spark plug can cause engine damage.
1. Disconnect the spark plug cap, and remove any dirt from around the spark plug area.
2. Remove the spark plug with a 13/16-inch spark plug wrench.
3. Inspect the spark plug. Replace it if the electrodes are worn heavy carbon buildup is found, or if the insulator is
cracked or chipped.
4. Measure the spark plug electrode gap with a suitable gauge. The gap should be 0.028-0.031 in (0.70 - 0.80 mm).
Correct the gap, if necessary, by carefully bending the side electrode.
5. Check that the spark plug washer is in good condition. Install the spark plug carefully, by hand, to avoid cross-threading.
6. After the spark plug seats, tighten with a 13/16-inch spark plug wrench to compress the sealing washer.
7. When installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer.
8. After the spark plug seats, tighten with a 13/16-inch spark plug wrench to compress the sealing washer. If reinstalling
the used spark plug, tighten 1/8 - 1/4 turn after the spark plug seats. If installing a new spark plug, tighten 1/2
turn after the spark plug seats.
9. Attach the spark plug cap.
NOTICE! The recommended spark plug has the correct heat range for normal engine operating temperatures. A loose
spark plug can overheat and damage the engine. Over tightening the spark plug can damage the threads in the cylinder
head.
