Operation
Using a hand-held edger
WARNING!
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!
Before edging, make sure the area Ŷ
is soft enough so the blade does not
bog down. If necessary, water the area
before edging.
Ŷ
Remove debris and other obstacles that
could be thrown by the rotating blade.
Adjusting 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:
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.
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 running 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.
CAUTION!
Low-speed edging can lead to premature clutch failure.
Guide Wheel
WARNING!
Use only Shindaiwa replace-
ment edger blades.
WARNING!
Never adjust the guide wheel
while the engine is running.
NOTE:
Guide wheel adjustment is also required
to compensate for blade wear.

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.
WARNING!
Before performing any maintenance, repair, 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.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
Air Filter
The C4 engine that powers your
Shindaiwa model is a hybrid 4-stroke
engine. As a hybrid, the engine is lubricated 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.
WARNING!
Non-standard accessories,
cutting attachment, or replacement
parts may not operate properly with
your unit and may cause damage and
lead to personal injury.
Blades
Keep blades sharp and check blade
condition frequently. If a blade’s performance changes suddenly, stop the
engine and check the blade for cracks
or other damage. Replace a damaged
blade IMMEDIATELY!
WARNING!
Never repair a damaged blade by
Ŷ
welding, straightening, or by modifying 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. Operating any unit with a blade or
attachment not approved for that
unit can be hazardous and may
cause serious injury.
Daily Maintenance
Prior to each work day, perform the
following:
Ŷ
Remove all dirt and debris from the
engine, check the cooling fins and
air cleaner for clogging, and clean as
necessary.
Ŷ
Clean any debris or dirt from the cutting attachment.
Check the entire unit for leaking fuel or
Ŷ
grease.
Check for loose or missing screws or
Ŷ
components. Make sure the cutter
attachment is securely fastened.
Ŷ
Make sure nuts, bolts, and screws
(except carburetor idle speed adjusting
screws) are tight.
Ŷ
Carefully remove any accumulations of
dirt or debris from the muffler and fuel
tank. Check cooling air intake area at
base of crankcase. Remove all debris.
Dirt build-up in these areas can lead to
engine overheating, fire, or premature
wear.

Maintenance (continued)
139/150-Hour Maintenance
Maintenance after first 139-hours,
then every 150-hours thereafter.
Ŷ
Combustion chamber should be decarbonized, and the valve clearance should
be adjusted. It is highly recommended
that this is done by a Shindaiwa-trained
service technician.
Valve Adjustment
Remove cylinder cover, rocker arm cover, 1.
and spark plug.
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.
CAUTION!
Ŷ
Performing a valve adjustment
incorrectly may cause hard starting and/or can damage the engine.
Ŷ
If you are unfamiliar with this
engine or uncomfortable with this
procedure, consult with an authorized Shindaiwa servicing dealer.
Rotate the crankshaft
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.
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.
Ŷ
The valve clearance should be adjusted
annually or every 135 hours. It is
highly recommended that this is
done by a Shindaiwa-trained service
technician.
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.
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!
Long Term Storage
Whenever the unit will not be used for 30
days or longer, use the following procedures to prepare it for storage:
Ŷ
Clean external parts thoroughly.
Drain all the fuel from the carburetor Ŷ
and the fuel tank.
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 starting, and could also lead to increased
service and maintenance costs.
14
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.
Ŷ
Remove the spark plug and pour
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.
Before storing the unit, repair or Ŷ
replace any worn or damaged parts.
Ŷ
Remove the air cleaner element from
the carburetor and clean it thoroughly
with soap and water, let dry and reassemble the element.
Ŷ
Store the unit in a clean, dust-free area.
