Be Aware of the Working Environment
Make sure bystanders or observers
outside the 50-foot “danger zone”
wear eye protection.
Avoid long-term operation
in very hot or very cold
weather.
Reduce the risk of
bystanders being struck
by flying debris. Make
sure no one is within 50
feet (15 meters)—that’s
about 16 paces—of an
operating attachment.
Be extremely
careful of
slippery terrain,
especially during
rainy weather.
50
FEET
AlwAys make sure
the appropriate cutting
attachment shield is
correctly installed.
Beware of a coasting blade when
edging. A coasting blade can injure
while it continues to spin after the
throttle trigger is released or after
the engine is stopped.
If contact is made with a hard
object, stop the engine and inspect
the cutting attachment for damage.
When operating in rocky terrain or
near electric wires or fences, use
extreme caution to avoid contacting
such items with the cutting attachment.
Be constantly alert for objects
and debris that could be thrown either
from the rotating cutting attachment
or bounced from a hard surface.

WARNING!
1. Place the unit on a flat, level surface.
Minimize the Risk of Fire!
2. Clear any dirt or other debris from
around the fuel filler cap.
NEVER start or operate this unit if
the carburetor, fuel lines, fuel tank
and/or fuel tank cap are damaged.
ALWAYS stop the engine and allow
it to cool before refueling. Avoid
overfilling and wipe off any fuel that
may have spilled.

Adjusting Engine Idle
The engine must return to idle speed
whenever the throttle lever is released.
Idle speed is adjustable, and must be set
low enough to permit the engine clutch to
disengage the cutting attachment.
1. Place the trimmer on the ground, then
start the engine and allow it to idle 2-3
minutes until warm.
2 If the attachment rotates when the
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise.

3. If a tachometer is available, the engine
speed should be adjusted to 3,000 ( 250)

WARNING!
The cutting attachment must never
rotate at engine idle! If the idle speed
cannot be adjusted by the procedure
described here, return the trimmer to
your Shindaiwa dealer for inspection.

Checking Unit Condition
NEVER operate the unit with the cutting
attachment shield or other protective de-
vices (ignition switch, etc.) removed!
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trim-
mer. Do not make modifications to your
machine without the written approval of
Shindaiwa, Inc.
AlwAys stop the engine immediately and
check for damage if you strike a foreign
object or if the unit becomes entangled.
Do not operate with broken or damaged
equipment.
WARNING!
AlwAys make sure the cutting attach-
ment is properly installed and firmly tight-
ened before operation.
NEVER allow the engine to run at high
rpm without a load. Doing so could damage
the engine.
A cutting attachment shield or other
protective device is no guarantee of
protection against thrown objects and
ricochet. YOU MUST ALWAYS GUARD
AGAINST FLYING DEBRIS!
NEVER use a cracked or warped cutting at-
tachment: replace it with a serviceable one.
NEVER operate the unit with worn or
damaged fasteners or cutting attachment
holders.
AlwAys make sure the cutting attach-
ment fits properly into the appropriate
attachment holder. If a properly installed
attachment vibrates, replace the attach-
ment with new one and re-check.
Edging with an Hand-held Edger

fast that the engine or blade bogs down.
Do not pull the unit backward over the
ground with the engine running. Doing
so will tend to bury the blade.
Regular and frequent use of the edger
will make a neater lawn, and a frequently
trimmed edge will be easier to maintain.
WARNING!
Wear eye protection, long pants, and
Figure 20
boots when operating this unit!
Guidelines for Operating the Edger
Whenever you strike a hard object
with the blade, always stop the edger
and carefully inspect the blade for
damage. NEVER OPERATE THE
EDGER WITH A DAMAGED BLADE!
Before edging, make sure the area is
soft enough so the blade does not bog
down. If necessary, water the area be-
fore edging.

Adjusting the Blade Cutting Depth
The edger’s depth of cut is controlled by a
combination of operator height, blade wear,
and the positioning of the edger’s guide
wheel.
To Adjust Blade Height:
1. Loosen the guide wheel adjusting knob.
See Figure 21.

2. Raise or lower the guide wheel to the
desired setting. See Figure 21a.
3. Tighten the guide wheel adjusting knob
firmly. See Figure 21.
WARNING!
Never adjust the guide wheel while the
engine is running.
NOTE:
Guide wheel adjustment is also required to
compensate for blade wear.

WARNING!
Never repair a damaged blade by
welding, straightening, or by modify-
ing its shape. An altered blade may
break during operation, resulting in
serious personal injury.
Muffler
This unit must never be operated with a
faulty or missing spark arrester or muf-
fler. Make sure the muffler is well secured
and in good condition. A worn or damaged
muffler is a fire hazard and may also cause
hearing loss.
Blades are not interchangeable
between Shindaiwa LE series edg-
ers and trimmer/brushcutter models.
Operating any unit with a blade or
attachment not approved for that
unit can be hazardous and may
cause serious injury.
Spark Plug
WARNING!
Keep the spark plug and wire connections
tight and clean.
Before performing any maintenance, re-
pair or cleaning work on the UNIT, make
sure the engine and cutting attachment
are completely stopped. Disconnect
the spark plug wire before performing
service or maintenance work.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
