WARNING!

Minimize the Risk of Fire

NEVER

 smoke or light fires near the engine.

ALWAYS

 stop the engine and allow it to cool 

before refueling. 

ALWAYS

 Wipe all spilled fuel and move at 

least 3 meters from the fueling point and 
source before starting.

ALWAYS 

inspect the unit for fuel leaks be-

fore each use. During each refill, check that 

no fuel leaks from around the fuel cap and/or 

ON

IMPORTANT!

Mix only enough fuel for your immediate 
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 STA-BIL™.

Starting the Engine 

4.  While holding the outer tube firmly with 

left hand. Use your other hand to slowly 

pull the recoil starter handle until resis-

tance is felt, then pull quickly to start the 

engine.

2.  Press the primer bulb until fuel can be seen 

flowing in the transparent return tube.

Make sure the 

cutting 

 

attachment

is clear of 

 

obstructions!

IMPORTANT!

Engine ignition is controlled by a two position switch mounted on the throttle housing labeled, “I” for ON or START and “O” for OFF 
or STOP.

IMPORTANT! 

The primer system only pushes fuel through 
the carburetor. Repeatedly pressing the primer 

bulb will not flood the engine with fuel.

CAUTION! 

Do not pull the recoil starter to the end 
of the rope travel. Pulling the recoil 
starter to the end of the rope travel can 
damage the starter.

Mixing Fuel

1.  Place the trimmer on a flat, level surface.
2.  Clear any dirt or other debris from around 

the fuel filler cap.

3.  Remove the fuel cap, and fill the tank with 

clean, fresh fuel.

4.  Reinstall the fuel filler cap and tighten firmly.

Filling the Fuel Tank

CAUTION!

This engine is designed to operate on a 50:1 
mixture consisting of unleaded gasoline and 
ISO-L-EGD or JASO FC class 2-cycle mix-
ing oil only. Use of non-approved mixing oils 
can lead to excessive carbon deposits.

CAUTION!

n

 

Some types of gasoline contain  
alcohol as an oxygenate. Oxygen-
ated gasoline may cause increased 
operating temperatures. Under cer-
tain conditions, alcohol-based gaso-
line may also reduce the lubricating 
qualities of some 2-cycle mixing oils. 

n

 

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 
engines, and should never be used 
in your Shindaiwa engine.

n

  Use only fresh, clean unleaded gasoline 

with a pump octane of 87 or higher.

n

  Mix all fuel with a 2-cycle air-cooled  

mixing oil that meets or exceeds  

ISO-L-EGD and/or JASO FC classified 

oils at 50:1 gasoline/oil ratio.

Examples of 50:1 mixing quantities

                Oil is a registered JASO FC 

classified oil and also meets or exceeds 

ISO-L-EGD performance requirements.  

Shindaiwa One is recommended for  

use in all Shindaiwa low emissions  

engines and also includes a fuel stabilizer.

1.  Slide the ignition switch to the “ON” 

position. See Figure 20.

3.  Set the choke lever to the CLOSED  

position if engine is cold.
