Checking Engine Oil
WARNING
Before lubricating, repairing, or inspecting, disengage all controls and stop
engine. Wait until all moving parts have come to a complete stop. Remove
the key to prevent unintended firing of the engine.
NOTE:
Check the oil level before each use to be sure correct oil level is maintained.
When adding oil to the engine, refer to viscosity chart below. Engine oil capacity
is approximately 37 ounces. Do not over-fill. Use a 4-stroke, or an equivalent high
detergent, premium quality motor oil certified to meet or exceed U.S. automobile
manufacturer’s requirements for service classification SG, SF. Motor oils classified
SG, SF will show this designation on the container.
1.
Remove the oil filler cap/dipstick and wipe the dipstick clean.
2.
Insert the cap/dipstick into the oil filler neck, but do
not
screw it in.
NOTE:
On some engines, a threaded screw cap will be present instead of
the quarter turn locking cap. In the instance of a threaded oil cap/dipstick,
DO NOT screw the cap/dipstick in to check. Check the oil by resting the cap/
dipstick on the threads, but not screwing it in.
3.
Remove the oil filler cap/dipstick. If level is low, slowly add oil until oil level
registers between high (H) and low (L). See Figure 18.
4.
Replace and tighten cap/dipstick firmly before starting engine.
