Mixing Fuel
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 or the carburetor, fuel lines, fuel tank and/or fuel
cap are damaged.
n NEVER smoke or light any res
near the engine or fuel source!
n NEVER place any ammable mate-
rial near the engine mufer!
n NEVER operate the engine without
the mufer and spark arrester in
good working condition.
Filling the Fuel Tank
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™.
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!
n Never use any type of gasoline
containing more than 10% alcohol
by volume! Some types of gasoline
contain alcohol as an oxygenate.
Oxygenated gasoline may cause
increased operating temperatures.
Under certain conditions, alcoholbased gasoline may also reduce the
lubricating qualities of some 2-cycle
mixing oils.
n Generic oils and some outboard oils
may not be intended for use in highperformance 2-cycle type 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 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
n 1 gallon of gasoline to 2.6 oz. mixing oil.
n 5 liters of gasoline to 100 ml. mixing oil.
WARNING!

WARNING!
Never start the engine from the operating position.
WARNING!
The cutting attachment may rotate
when the engine is started!
When the Engine Starts...
n After the engine starts, allow the engine
to warm up at idle 2 or 3 minutes before
operating the unit.
n After the engine is warm, pick up the
unit and clip on the shoulder strap if so
equipped.
n Advancing the throttle makes the cut-
ting attachment turn faster; releasing
the throttle permits the attachment to
stop turning. If the cutting attachment
continues to rotate when the engine
returns to idle, carburetor idle speed
should be adjusted.
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.
6. When the engine starts, slowly move the
choke lever to the “OPEN” position. See

WARNING!
n When cutting wood with a blade, feed
the blade slowly never strike or “slam”
the spinning blade against the wood.
n DO NOT use 2-tooth or non-
Shindaiwa approved 4-tooth cutting
blades with Shindaiwa trimmers and
brushcutters.
The blade rotates counter-clockwise. For
best performance and to minimize being
struck by debris, move the blade from
right to left while advancing on your work.
Position the blade so cuts are made
between the blade’s 8 o’clock and 10
o’clock positions (as viewed from above).
DO NOT cut between the 10 o’clock and 5
o’clock positions. See Figure 27.
Cut on the left
side of the blade.
KEEP YOUR BODY
OUTSIDE THE
PATH OF BLADE
ROTATION
Hold the brushcutter with the blade at
a 90° angle to the ground so the blade’s
bottom edge rotates toward the operator. Move the blade from top to bottom
through the cut, and cut only with the bottom edge of the blade. See Figure 28.

Vertical Cuts
Blade Thrust
‘Blade thrust’ is a sudden sideways or
backward motion of the brushcutter. Such
motion may occur when the blade jams or
catches on an object such as a sapling tree
or tree stump. BE CONSTANTLY ALERT
FOR BLADE THRUST AND GUARD
AGAINST ITS EFFECTS!
Brushcutter Handlebar
A brushcutter’s handlebar or barrier bar
helps prevent the operator from moving forward or the unit moving rearward; thus preventing inadvertent bodily
contact with the blade. ALWAYS KEEP
THE HANDLEBAR OR BARRIER BAR
SECURELY IN PLACE ON THE UNIT!
Brushcutter Shoulder Strap
A shoulder strap provides additional protection against blade thrust. Plus, a shoulder strap gives significant support and
comfort to help ensure safe and efficient
operation.
When operating a trimmer or brushcutter,
make sure both the handle and shoulder
strap are adjusted to the size of the operator using the unit.
Using A Brushcutter Blade C270
WARNING!
n Before working with a blade-
equipped unit, always inspect and
clean the area of objects that could
interfere with or damage the blade.
n Never use a blade near sidewalks,
fence posts, buildings or other
objects that could cause injury or
damage.
n Never use a blade for purposes other
than those for which it was designed.
n Whenever you strike a hard object
with a blade, always stop the
brushcutter and carefully inspect
the blade for damage. NEVER
OPERATE THE BRUSHCUTTER
WITH A DAMAGED BLADE!
n A blade-equipped unit must be
equipped with a bicycle-type handlebar or barrier bar as well as a
harness or shoulder strap.
n Always make sure the cutting
attachment shield is properly
installed before operating the unit.
Engine Operating Speeds
Operate the unit at full throttle while cutting. Best fuel efficiency is obtained by
releasing the throttle when swinging back
after a cut.
n To prevent possible engine damage, do
not allow the brushcutter to run at high
speeds without a load.
n Avoid operating the engine at low
speeds. Doing so can lead to rapid
clutch wear. In addition, slow-speed
operation tends to cause grass and
debris to wrap around the cutting head.
