ADDING/CHECKING ENGINE LUBRICANT
See Figure 8.
Engine lubricant has a major influence on engine perfor-
mance and service life. This unit is shipped with a 20W50
engine lubricant to assist in the break-in period. For best
operating performance, continuing to use 20W50 engine
lubricant is recommended, however, SAE 30, 10W30, or
10W40 are all acceptable lubricants to use in this product.
Always use a 4-stroke motor lubricant that meets or exceeds
the requirements for API service classification SJ. Check
lubricant level before each use.
NOTE: Non-detergent or 2-stroke engine lubricants will
damage the engine and should not be used.
To add engine lubricant:

Remove the cap and seal from lubricant bottle
provided.
 Unscrew the oil cap/dipstick and remove.
 Using the funnel provided, add one entire bottle of engine
lubricant through oil fill hole.
 Reinstall the oil cap/dipstick and secure.
To check engine lubricant level:

Place unit on a flat surface.
 Wipe dipstick clean and re-seat in hole; do not rethread.
 Remove dipstick again and check lubricant level. Lubricant
level should fall within the hatched area on the dipstick.
 If level is low, add engine lubricant until the fluid level rises
to the upper portion of the hatched area on the dipstick.
 Replace and secure the oil cap/dipstick.
CAUTION:
Do not overfill. Overfilling the crankcase may cause
excessive smoke, oil loss, and engine damage.
