Filling the Fuel Tank
Mixing Fuel
CAUTION!
Some gasolines contain alcohol as
an oxygenate! Oxygenated fuels
may cause increased operating
temperatures. Under certain
conditions, alcohol-based fuels
may also reduce the lubricating
qualities of some mixing oils.
Never use any fuel containing
more than 10% alcohol by volume!
Generic oils and some outboard
motor oils may not be intended for
use in high-performance air cooled
2-cycle engines, and 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 a Premium
2-cycle mixing oil only. Use of
Non-approved mixing oils can lead
to excessive maintenance costs
and/or engine damage.
■
Use only fresh, clean unleaded
gasoline with a pump octane rating
of 87 or higher.
■
Mix gasoline with 50:1 Shindaiwa
Premium 2-cycle mixing oil or with
an equivalent high quality 2-cycle
mixing oil.
Example of 50:1 mixing quantites:
■
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 Shindaiwa
One oil with fuel stabilizer is not
used, it should first be treated with a
fuel stabilizer such as StaBil™.
WARNING!
Minimize the risk of fire!
■
Stop the engine before refuel-
ing.
■
Always allow the unit to cool
before refueling!
■
Wipe all spilled fuel and move
the unit at least 10 feet (3
meters) from the fueling point
before restarting!
■
Never smoke or light any fires
near the unit or fuels!
■
Never place any flammable
material near the engine
muffler!
■
Never operate the engine
without the muffler and spark
arrester in place and properly
functioning!
■
Never operate this hedge
trimmer if fuel system compo-
nents are damaged or are
leaking!

cleaner or element is damaged, or
if the element is wet.
Every 10 hours of operation,
(more frequently in dusty or
dirty conditions):
Remove the air cleaner element from
the air cleaner housing and clean it
thoroughly with soap and water. Rinse
and dry thoroughly. Add a few drops
of oil and work it in, then reassemble.
See Figure 20.
CAUTION!
Before removing the spark plug,
clean the area around the plug to
prevent dirt and debris from
getting into the engine’s internal
parts.
Every 10 to 15 hours
of operation:
■
Remove and clean the spark plug.
See Figure 21. Adjust the spark
plug electrode gap to 0.024-inch
(0.6 mm). If the plug must be
replaced, use only:
–For EPA version: Champion CJ8
–For EMC version (electromagnetic
compatibility, required in Australia):
NGK BMR6A or an equivalent
spark plug of the correct heat
range.
