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!
Mix and pour fuel outdoors where there

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.
WARNING!
The cutters must NEVER
engage at engine idle speeds! If the
idle speed cannot be adjusted by the
procedure, described here, contact
your authorized Shindaiwa servicing
dealer.
Operation
Squeezing the throttle increases Ŷ
engine speed, causing the clutch to
engage and operate the cutters.
Idle Speed Adjustment
Place the trimmer on the ground, then 1.
start the engine, and then allow it to idle
2-3 minutes until warm.
If the attachment rotates when the 2.
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise.
If a tachometer is available, the engine 3.
idle speed should be final adjusted to
the values in the Specification section..
NOTE
Carburetor fuel mixture adjustments are
preset at factory and cannot be serviced

engine speed, causing the cutters to
slow, and then stop altogether as the

Throttle free play adjustment
If the unit does not return to idle speed
or doesen’t reach full rpm, the throttle
lever free play may need to be adjusted as
follows:
Measure free play at the end of the 1. throttle lever. Throttle lever free play should
be approximately 5-7 mm (0.2-0.275”).
If adjustment is necessary, remove the 2.
air cleaner cover by loosening the two
thumbscrews. Loosen the cable adjuster

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.
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.
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
