Mixing Fuel; Starting The Engine - Shindaiwa 81643 Owner's/Operator's Manual

Mixing Fuel

CAUTION!
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. 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 air cooled
2-cycle engines, and should never be
used in your Shindaiwa engine.
Filling the Fuel Tank
WARNING!
Minimize the risk of fire!
n STOP engine before refueling.
n ALWAYS allow the engine to cool
before refueling!
n Wipe all spilled fuel and move the
engine at least 10 feet (3 meters)
from the fueling point and source
before restarting!
n NEVER start or operate this unit if
there is a fuel leak.

Starting the Engine

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.

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 mixing oil only. Use of
non-approved mixing oils can lead to
excessive carbon deposits.
n Use only fresh, clean unleaded gasoline
with a pump octane of 87 or higher.
n Mix all fuel with a -cycle air-cooled
mixing oil that meets or exceeds
ISO-L-EGD and/or JASO FC classified
oils at 50:1 gasoline/oil ratio.
n NEVER start or operate this unit if
the carburetor, fuel lines, fuel tank
and/or fuel tank cap are damaged.
n NEVER smoke or light any fires
near the engine or fuel source!
n NEVER place any flammable
material near the engine muffler!
n NEVER operate the engine without
the muffler and spark arrester in
good working condition.
IMPORTANT!!
The primer system only pushes fuel
ON
through the carburetor. Repeatedly
pressing the primer bulb will not flood the
engine with fuel.

3. Set the choke lever to the CLOSED
position if engine is cold.
IMPORTANT!
Examples of 50:1 mixing quantities
n 1 gallon of gasoline to .6 oz. mixing oil
n 5 liters of gasoline to 100 ml. mixing oil
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™.
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. Shindaiwa
One also includes a fuel stabilizer.
1. Place the trimmer on a flat, level surface.
. 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.
