HOW TO PREPARE THE ENGINE
ENGINE DOES NOT CONTAIN
OIL OR GASOLINE
See the engine manufacturer’s instructions
for the type of gasoline and oil to use. Before
you use the unit, read the information on
safety, operation, maintenance, and storage.
This Edger was shipped with a 20 ounce
container of SAE30 motor oil. Add this oil to
the engine before operating. To fill the crank-
case, remove the oil fill cap/dipstick and add
the SAE30 motor oil. DO NOT OVERFILL.
NOTE: The engine may contain a small
amount of oil. When adding oil, frequently
insert the oil fill cap/dipstick and check
the amount of oil in the engine. DO NOT
OVERFILL.
WARNING: Follow the engine
manufacturer’s instructions for
the type of gasoline and oil to
use. Always use a safety gasoline con-
tainer. Do not smoke when adding gaso-
line to the engine. When inside an en-
closure, do not fill with gasoline. Before
you add gasoline, stop the engine. Let
the engine cool for several minutes.
IMPORTANT: This unit is equipped with an
internal combustion engine and must not
be used on or near any unimproved forest–
covered, brush–covered or grass–covered
land unless the engine’s exhaust system is
equipped with a spark arrester meeting ap-
plicable local or state laws (if any). If a
spark arrester is used, it must be main-
tained in effective working order by the op-
erator.
In the State of California the above is re-
quired by law (Section 4442 of the Califor-
nia Public Resources Code). Other states
may have similar laws. Federal laws apply
on federal lands. See an Authorized Ser-
vice Center for a spark arrester for the muf-
fler.

HOW TO USE THE INDEX LEVER
Bevel edging cuts a trench and reduces the
need to edge as often.

EDGING position and move to the
BEVEL position.
3. Reconnect the spark plug wire to the
spark plug.
4. Start the engine.
5. Move the depth control lever to the de-
sired height.
NOTE: For deep edging, first cut at shal-
low depths. Then, cut at greater depths
until the desired depth is obtained.
WARNING: While the engine is
running, never leave the Edger.
Before you adjust the wheels or
change the blade position, always dis-
engage the cutting blade and stop the
engine.
