Mixing fuel
Mixing fuel
CAUTION!
Never use any type of gasoline containing more than 10% alcohol by volume! Some types of gasoline contain
alcohol as an oxygenate. Oxygenated
gasoline may cause increased operating temperatures. Under certain conditions, alcohol-based gasoline may
also reduce the lubricating qualities of
some 2-cycle mixing oils.
Generic oils and some outboard
oils should never be used in your
Shindaiwa engine.
CAUTION!
This engine is designed to operate on
a 50:1 mixture consisting of unleaded
gasoline and ISO-L-EGD or JASO FD
class 2-cycle mixing oil only. Use of
non-approved mixing oils can lead to
excessive carbon deposits.
Use only fresh, clean unleaded gasoline Ŷ
with a pump octane of 87 or higher.
Ŷ
Mix all fuel with a 2-cycle air-cooled
mixing oil that meets or exceeds ISO-LEGD and/or JASO FD classified oils at
50:1 gasoline/oil ratio.
CAUTION!

Operation
Using the Hedge Trimmer
Preparations
Use lopping shears to cut out thick
branches first.
Cutting Sequence
If a radial cut is necessary, cut a little at a
time in several passes.
Cutting Techniques
Vertical Cut:
Swing the blade up and down in an arc as
you move along the hedge. Use both sides
of the cutting blade.
Cut without standing directly next to the
hedge, e.g. with a flower bed between
operator and hedge.
Overhead Cut:
Hold the shaft upright with a 90° blade
angle to cut an upper surface of a hedge.
Horizontal Cut:
Hold the cutting blade at an angle of 0°
to 10° as you swing the hedge trimmer
horizontally.
Swing the blade in an arc towards the
outside of the hedge so that the cuttings
are swept on to the ground.
Cut without standing directly in front of the
hedge, e.g. reach over a flower bed.
Cut close to the ground from a standing position, e.g., for low shrubs.

Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
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.
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.
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
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.
WARNING!
Always wear gloves when
working around the cutter assembly.
Lubricate the blades before use and Ŷ
after refueling. Check the cutters for
damage or incorrect adjustment.
Ŷ
Clean any debris or dirt from the cutting attachment.

Maintenance (continued)
50-hour maintenance
Every 50 hours of operation; more frequently in dusty conditions:Remove and
clean the cylinder cover and clean dirt and
debris from the cylinder cooling fins.
Remove and replace the fuel filter
element.
Use a hooked wire to extract the fuel filter
Ŷ
from inside the fuel tank. Inspect the fuel
filter element. If it shows signs of contamination, replace with a genuine Shindaiwa
replacement fuel filter element.
CAUTION!
Make sure you do not pierce the fuel line
with the end of the hooked wire. The line
is delicate and can be damaged easily.
Before reinstalling the new filter element,
inspect the condition of all the fuel
system components (fuel pick-up line,
fuel return line, tank vent line, tank
vent, fuel cap and fuel tank). If damage,
splitting or deterioration is noted, the
unit should be removed from service
until it can be inspected or repaired by a
Shindaiwa-trained service technician.
Gearcase lubrication
To perform this operation, first remove the
gearcase from the outer tube as follows:
Loosen the gearcase clamp bolt.1.
Remove the index bolt from the 2.
gearcase.
CAUTION!
Do not remove the D-shaped shim
washer from the gearcase clamp! The

Ŷ
Combustion chamber should be decar-
bonized, 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.
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.
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!
Cutter blade adjustment
WARNING!
The cutter blades are very
sharp! Always wear gloves when working around the cutter assembly.
Cutting performance of your machine
depends a great deal on proper cutter blade
adjustment. Properly adjusted blades will
oscillate freely yet help prevent binding of
cut material between blades. Adjust blades
as follows:
Loosen all blade locknuts at least one 1.
full turn.
Tighten each blade shoulder bolt 2.
firmly, and then loosen the shoulder
bolts 1/4 to 1/2 turn.
Working from the gearcase end, lock 3.
each bolt in place by firmly tightening
its locknut while preventing the shoulder bolt from turning.
When shoulder bolt adjustment is correct, there should be a gap of 0.25–0.50
mm between the cutter blades and the flat
washers, and the flat washer beneath each
bolt head should turn freely.
CAUTION!
Operating the trimmer with worn or
improperly adjusted cutters will reduce
cutter performance and may also damage your machine. Never operate the
machine with damaged or worn cutters.
