Operation
Using a hand-held edger
CAUTION!
Low-speed edging can lead to pre-
mature clutch failure.
Before edging, make sure the area Ŷ
is soft enough so the blade does not
bog down. If necessary, water the area
before edging.
Remove debris and other obstacles that
Ŷ
could be thrown by the rotating blade.
Wear eye protection, long pants,
Ŷ
and boots when operating this
machine!
Whenever you strike a hard object
Ŷ
with the blade, always stop the edger
and carefully inspect the blade for
damage. NEVER OPERATE THE
EDGER WITH A DAMAGED BLADE!
WARNING!
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:
Loosen the guide wheel adjusting knob.1.
Raise or lower the guide wheel to the 2.
desired setting.
Tighten the guide wheel adjusting knob 3.
firmly.
NOTE:
Guide wheel adjustment is also required
to compensate for blade wear.
Adjusting blade cutting depth
Plan your work so the edger blade is Ŷ
always on your right-hand side.
Begin each pass by positioning the unit
Ŷ
over the work, and with the engine run-
ning at about half-throttle. Slowly lower
the blade to the ground while applying
full throttle.
Do not move the edger into the work so Ŷ
fast that the engine or blade bogs down.
Regular and frequent use of the edger
Ŷ
will make a neater lawn, and a frequently
trimmed edge will be easier to maintain.
WARNING!
Use only Shindaiwa replace-
ment edger blades.
WARNING!
Never adjust the guide wheel
while the engine is running.

Air Filter
The C4 engine that powers your
Shindaiwa model is a hybrid 4-stroke
engine. As a hybrid, the engine is lubri-
cated by oil mixed with the gasoline
and air from the carburetor that moves
through and around the internal parts of
the engine in a similar way that a 2-stroke
engine is lubricated. Without the heavy
duty 2-stage air filter equipped on all C4
engines, dust and dirt could also move
through the engine, decreasing engine
life, increasing valve wear and the need
for more frequent valve adjustments. To
keep your C4 engine strong and reliable,
Shindaiwa recommends that you check
and service the air filter as instructed in
the 10-Hour Maintenance section that
follows.
0XIÁHU
This unit must never be operated with
a faulty or missing spark arrester or
muffler. 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.
Spark Plug
Keep the spark plug and wire connections
tight and clean.
General Maintenance
Blades
Keep blades sharp and check blade
condition frequently. If a blade’s per-
formance changes suddenly, stop the
engine and check the blade for cracks
or other damage. Replace a damaged
blade IMMEDIATELY!
Never repair a damaged blade by
Ŷ
welding, straightening, or by modify-
ing its shape. An altered blade may
break during operation, resulting in
serious personal injury.
Blades are not interchangeable Ŷ
between Shindaiwa edgers and
unit/brushcutter models. Oper-
ating any unit with a blade or
attachment not approved for that
unit can be hazardous and may
cause serious injury.

Whenever the unit will not be used for 30
days or longer, use the following proce-
dures to prepare it for storage:
Clean external parts thoroughly.
Ŷ
Drain all the fuel from the carburetor Ŷ
and the fuel tank.
Long Term Storage
Remove remaining fuel from the fuel Ŷ
lines and carburetor with the fuel
drained from the fuel tank. To do so:
Prime the primer bulb until no more 1.
fuel is passing through.
Start and run the engine until it stops 2.
running.
Repeat steps 1 and 2 until the engine 3.
will no longer start.
Remove the spark plug and pour
Ŷ
about 7 mL (1/4 oz.) of 2-cycle mixing
oil into the cylinder through the spark
plug hole. Slowly pull the recoil starter
2 or 3 times so oil will evenly coat the
interior of the engine. Reinstall the
spark plug.
IMPORTANT!
All stored fuels should be stabilized with a
fuel stabilizer such as STA-BIL.
CAUTION!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.
Before storing the unit, repair or Ŷ
replace any worn or damaged parts.
Remove the air cleaner element from
Ŷ
the carburetor and clean it thoroughly
with soap and water, let dry and reas-
semble the element.
Store the unit in a clean, dust-free area.
Ŷ
Maintenance (continued)
IMPORTANT!
If a new gasket is not available and/or the
old gasket is not damaged, the old gasket
may be reused. Never use cracked or
damaged gaskets!
Turn engine over several times, and 6.
returnthe to TDC-compression.
Recheck with proper feeler gauge to
make sure clearance adjustment did
not change as a result of tightening the
locknut. Readjust as necessary.
Replace rocker arm cover gasket to 7.
assure proper sealing and install cover.
Remove cylinder cover, rocker arm cover, 1.
and spark plug.
Rotate the crankshaft
while observing the piston through the
spark plug opening. When the piston
is at the top of the compression stroke
(TDC), the valves can be adjusted.
Loosen adjuster locknut so that the 2.
2.5 mm Allen socket head adjustment
screw can turn freely.
Insert 0.10 mm feeler gauge between 3.
valve stem tip and rocker arm.
Turn adjustment screw (clockwise = 4.
tighter, counter-clockwise = looser)
until feeler gauge is almost snug. Back
off just enough to allow gauge to slip
out with limited resistance.
While holding the adjustment screw in 5.
place with the Allen driver, tighten the
locknut with a wrench.
CAUTION!
Performing a valve adjustment
Ŷ
incorrectly may cause hard start-
ing and/or can damage the engine.
If you are unfamiliar with this
Ŷ
engine or uncomfortable with this
procedure, consult with an autho-
rized Shindaiwa servicing dealer.
Valve Adjustment
139/150-Hour Maintenance
Maintenance after first 139-hours,
then every 150-hours thereafter.
Combustion chamber should be decar-
Ŷ
bonized, and the valve clearance should
be adjusted. It is highly recommended
that this is done by a Shindaiwa-trained
service technician.
Replace the spark plug annually: Use
Ŷ
only the type recommended in the
”Specifications” section or an equivalent
resistor type spark plug of the correct
heat range. Set spark plug electrode
gap to 0.6 -0.7 mm.
The valve clearance should be adjusted
Ŷ
annually or every 135 hours. It is
highly recommended that this is
done by a Shindaiwa-trained service
technician.
