Engine Fuel; Starting The Engine - Shindaiwa 81601 Owner's/Operator's Manual

Mixing Fuel
CAUTION!
Some types of gasoline contain
alcohol as an oxygenate. Oxygenated
gasoline may cause increased operat-
ing temperatures. Under certain condi-
tions, 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-perfor-
mance C4 engines, and should never
be used in your Shindaiwa engine.
Filling the Fuel Tank
WARNING!
Minimize the risk of fire!
n ALWAYS stop the engine and al-
low 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 starting!
n NEVER start or operate this
unit if there is a fuel leak.

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.
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
n NEVER start or operate this
unit if the carburetor, fuel lines, fuel
tank and/or fuel tank cap are dam-
aged.
n NEVER smoke or light any fires
near the engine or fuel source!
n NEVER place any flammable mate-
rial near the engine muffler!
n NEVER operate the engine without
the muffler and spark arrester in
good working condition.
IMPORTANT!
IMPORTANT!
The primer system only pushes fuel
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.
Mix only enough fuel for your immediate
needs! If fuel must be stored longer than
30 days and
is not used, it should first be treated with
a fuel stabilizer such as StaBil™.
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 en-
gines. 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.
