ADDING/CHECKING ENGINE LUBRICANT
See Figure 8.
NOTE: This machine has been shipped with approximately
2 oz. of lubricant in the engine from testing. You must add
lubricant to the engine before starting it the first time.
NOTICE:
Any attempt to start the engine without adding lubricant
will result in engine failure.
To add engine lubricant:
 Place mower on a flat, level surface. Do not tilt.
 Unscrew the oil cap/dipstick by turning counter-clockwise.
 Before first use, squeeze the entire contents of the lubri-
cant container provided into the oil reservoir.
After initial use, add 4-stroke engine lubricant (SAE 30 or
SAE 10W30) until the fluid level rises to the upper portion
of the hatched area on the dipstick. Do not overfill.
 Replace the oil cap/dipstick and securely tighten.
To check engine lubricant level:
 Place mower on a flat, level surface. Do not tilt.
 Unscrew the oil cap/dipstick by turning counter-clockwise.
 Wipe dipstick clean and re-seat in hole; do not rethread.

level should fall within the hatched area on the dipstick.

to the upper portion of the hatched area on the dipstick.
 Replace and secure the oil cap/dipstick.
NOTICE:
Do not overfill. Overfilling the crankcase may cause ex-
