Operating Precautions
■Always make sure the cutting
attachment tool is properly
installed and firmly tightened
before operation.
■Never use a cracked or
warped cutting attachment:
replace it with a serviceable
one and make sure it fits
properly.
■Keep the unit away from
excessive heat. Engine fuel is
very flammable and fire could
lead to serious personal injury
or property damage.
■Make sure there are no
missing or loose fasteners,
and that the stop switch and
throttle controls are working
properly.
WARNING!
■Before starting the engine,
make sure the cutting
attachment is not contacting
anything.
■Always stop the engine
immediately and check for
damage if you strike a foreign
object or if the unit becomes
tangled. Do not operate with
broken or damaged equip-
ment.
■Never transport the unit or set
it down with the engine
running. An engine that’s
running could be accidently
accelerated causing the
cutting attachment to rotate.
■Make sure cutter safety
guards are in place when
transporting the unit.
Never extend trimming line
beyond the length specified for
your unit.
Always keep the unit as clean as
practical. Keep it free of loose
vegetation, mud, etc.

MAINTENANCE
Long Term Storage
Whenever the unit will not be used for
30 days or longer, use the following
procedures to prepare it for storage:
■Clean external parts thoroughly
and apply a light coating of oil to all
metal surfaces.
■Drain all the fuel from the carbure-
tor and the fuel tank.

CAUTION!
This engine is designed to operate
on a 50:1 mixture consisting of
unleaded gasoline and 2-cycle
mixing oil only. Use of non-
approved mixing oils can lead to
excessive carbon deposits.
CAUTION!
Some types of gasoline contain
alcohol as an oxygenate. Oxygen-
ated gasoline may cause in-
creased operating temperatures.
Under certain conditions, alcohol-
based gasoline may also reduce
the lubricating qualities of some 2-
cycle mixing oils. Never use any
type of gasoline containing more
than 10% alcohol by volume!
Generic oils and some outboard
oils may not be intended for use in
high-performance 2-cycle type
engines, and should never be
used in your Shindaiwa engine.
■Use only fresh, clean unleaded
gasoline with a pump octane of 87
or higher.
■
Mixed with 50:1 Shindaiwa Premium
2-cycle mixing oil or with an equivalent
high quality 2-cycle mixing oil.
Examples of 50:1 mixing quantities
■ 1 gallon of gasoline to 2.6 oz. mixing oil
■ 5 litres of gasoline to 100 ml. mixing oil
IMPORTANT!
Mix only enough fuel for your immedi-
ate needs! If fuel must be stored
longer than 30 days and oil with
fuel stabilizer is not used, it should
first be treated with a fuel stabilizer
such as StaBil™.

10-Hour Maintenance
Every 10 to 15 hours of operation:
Remove and clean the spark plug. Adjust
the spark plug electrode gap to 0.024-
inch (0.6 mm). If the spark plug must be
replaced, use only a Champion CJ8 or
equivalent spark plug of the correct
heat range. (For electro magnetic
compliance (EMC) use a NGK BMR6A
resistor plug.) See Figure 16.
CAUTION!
Before removing the spark plug,
clean the area around the plug to
prevent dirt and debris from falling
into internal engine parts.
Clean the spark plug
and check the gap
at the electrode.
Every 10 hours of operation (more
frequently in dusty or dirty conditions):
Remove the air cleaner element. See
figure 15. Clean or replace as neces-
sary. To clean element: Wash it
thoroughly in soap and water. Let it
dry before reinstalling the element.
CAUTION!
Do not operate the unit if the air
cleaner or element is damaged,
or if the element is wet.

Starting the Engine (continued)
WARNING!
Never start the engine from the
operating position.
WARNING!
The cutting attachment may move
when the engine is started!
When the Engine Starts...
■After the engine starts, allow the
engine to warm up at idle 2 or 3
minutes before operating the unit.
■After the engine is warm, pick
up the unit and clip on the harness
if so equipped. See
page 14.
■Advancing the throttle makes the
cutting attachment turn faster;
releasing the throttle permits the
attachment to stop turning. If the
cutting attachment continues to
move when the engine returns to
idle, carburetor idle speed should
be adjusted (see the next page).
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed
position, the engine may be flooded
with fuel. If flooding is suspected,
move the choke lever to the open
position and repeatedly pull the recoil
starter to remove excess fuel and start
the engine. If the engine still fails to
start, refer to the troubleshooting
section of this manual.
5. When the engine starts, slowly
move the choke lever to the
"OPEN" position. See Figure 11.
(If the engine stops after the initial
start, close the choke and restart.)

General Maintenance
Muffler
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 connec-
tions tight and clean.
Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws)
are tight.
Daily Maintenance
Prior to each work day, perform the
following:
■Check for loose or missing screws
or components. Make sure the tool
and cutting attachment are securely
fastened.
■Check the entire unit for leaking
fuel or grease.
■Remove dirt or debris from the
engine, check the cooling fins and
air cleaner for clogging and clean
them as necessary.
■Carefully remove any accumulation
of dirt or debris from the muffler or
the fuel tank. Dirt build-up in these
areas could cause the engine
overheating, induce premature
wear, or create a fire hazard.
MAINTENANCE
WARNING!
Before performing any mainte-
nance, 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 work.
WARNING!
Non-standard parts may not
operate properly with your unit and
may cause damage and lead to
personal injury.
NOTE:
Using non-standard replacement
parts could invalidate your Shindaiwa
warranty.

OPERATION
OPERATION
13
Idle the engine briefly before
stopping(about 2 minutes), then slide
the ignition switch to the “O” (OFF)
position. See Figure 12.
The engine must return to idle speed
whenever the throttle lever is re-
leased. Idle speed is adjustable, and
must be set low enough to permit the
engine clutch to disengage the cutting
attachment.
Idle Speed Adjustment
1. Place the Multipurpose Trimmer
Tool Carrier on the ground, then
start the engine, and then 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 adjust-
ment screw counter-clockwise. See
Figure 13.
3. If a tachometer is available, the
engine idle speed should be final
adjusted to 2,750 (±250) rpm (min-1).
4. Carburetor fuel mixture adjust-
ments are preset at factory and
cannot be serviced in the field.
