OPERATION
ADDING/CHECKING ENGINE LUBRICANT
See Figure 8.
NOTICE:
Attempting to start the engine before it has been properly
filled with lubricant will result in equipment failure.
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. Lubri-
cant level should fall within the 2 squares on dipstick.
 If level is low, add engine lubricant until the fluid level
rises to the upper portion of the dipstick.
 Replace and secure the oil cap/dipstick.
NOTICE:
Do not overfill. Overfilling the crankcase may cause
excessive smoke, oil loss, and engine damage.

CUTTING TIPS
See Figure 14.

Keep a firm grip with both hands while in operation.
 If grass becomes wrapped around the string head, STOP
THE ENGINE, disconnect the spark plug wire, and remove
the grass.
 Use the tip of line to do the cutting; do not force string
head into uncut grass.
 Wire and picket fences cause extra line wear, even
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.
 Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the line.
TRANSPORTING THE UNIT
 Flip on/stop switch to STOP ( O ) position.
 Make sure engine and exhaust are cool.

Keep unit level to prevent fuel spillage.
