Adjusting the Engine
6-1 Filling the Fuel Tank
WARNING!
When adding fuel, make sure
the engine is stopped and cooled-down.
Filling or mixing fuel and oil must be
done away from any fires or other igni-
tion sources. When any fuel leakage is
found, take the machine to a Shindaiwa
dealer for repair. Never use the ma-
chine with fuel leaking. This may result
in serious injury.
CAUTION!
This engine is designed to operate only
on a 50:1 mixture consisting of un-
leaded gasoline and a premium 2-cycle
mixing oil. Use of non-approved mixing
oils can lead to excessive maintenance
costs and/or engine damage.
(1) Turn the fuel cap counterclock-
wise and take it off.
(2) With the fuel cap hanging down
from the filler opening, fill the fuel
tank with fresh, clean fuel (mixture
of fuel and oil) and tighten the fuel
cap securely.
(3) If there is any fuel spilt on the
machine, make sure it is wiped off
completely.
WARNING!
MAKE SURE THE BLADE
IS WELL CLEAR OF ANY
INTERFERENCE. Before starting the
engine, place unit on clean, level sur-
face. Make sure you have good se-
cure footing and always keep a firm
grip on the machine. THE CUTTING
ATTACHMENT MAY ROTATE
WHEN THE ENGINE STARTS.
6-2 Starting the Engine
WARNING!
Move at least three meters
away from the fuel site be-
fore starting the engine.
WARNING!
Never operate the engine
without the cutting attach-
ment installed.
(1) Starting a Cold Engine and/or
Restarting After Refueling.
(a) Slide the ON-OFF switch to the “I”
position.
(b) Prime the engine by repeatedly
depressing the carburetor primer
bulb until fuel can be seen flowing
through the transparent overflow
return tube:
(c) Push the choke lever upward
(“ “ position).
(d) (C220) Depressing the lock lever,
pull the throttle lever fully and
depress the throttle lock button.
While depressing the throttle lock
button, release the throttle lever and
the lock lever. Now the throttle stays
at high idle (starting speed).
(e) While firmly holding the outer
tube with one hand, pull the coil
starter handle upward with your
other hand. Pull slowly at first until
you feel the starter engage, then pull
quickly to start the engine. Do not
pull the starter rope to the end of its
travel.
CAUTION!
Pulling the starter rope to the end of its
travel may damage the starter
mechanism.

12
IMPORTANT!
Repeated cranking of the engine with
the choke CLOSED (“ “) will lead to
engine flooding. If the engine fails to
start after several attempts, move the
choke lever to the OPEN position and
continue cranking.
(f) When the engine first fires, gradu-
ally return the choke to OPEN
(“ ”) position if you have not
already done so.
• If the engine stops before the choke
is fully open, restart with the choke
closed.
• If the engine stops after the initial
firing, restart with choke closed.
(g) [C220] When the engine starts
and is running, set the engine to idle
by tapping the throttle lever to
release the throttle lock.
WARNING!
Never start the engine from
the operating position.
(2) Starting a Warm Engine
Starting a warm engine involves all of
the steps of starting a cold engine.
EXCEPT:
• Do not press the primer bulb, and
• The choke should be in the OPEN
position.
If the engine does not start, follow
the cold engine starting procedure.
(3) When the engine starts:
• After the engine starts, disengage
the throttle lock and allow the engine
to warm-up at idle for 2 or 3 minutes
before operating the machine.
• After the engine is warm, pick-up
the machine and clip on the strap.
• Advancing the throttle allows the
cutting attachment to rotate faster;
releasing the throttle allows the
attachment to stop. If the cutting
attachment continues to rotate,
carburetor idle speed should be
adjusted.
WARNING!
The cutting attachment
continues rotating for a
while after the switch is turned off.
Idle the engine briefly before stop-
ping, then slide the ON-OFF switch
to the “O” (for STOP) position.
6-3 Stopping the Engine
WARNING!
The cutting attachment
should NEVER rotate
at engine idle.
Start the engine and allow it to
warm up at low rpm. If the cutting
attachment rotates at engine idle,
reduce idle adjust screw counter-
clockwise.
WARNING!
When adjusting the
engine, the cutting attach-
ment may rotate. Make sure the
cutting attachment is well clear of
any interference.
NOTE:
Standard idle speed is 2,900(min–1)RPM.

8 Operation
8-2 Standard Shoulder Strap
Adjust the shoulder strap so the
shoulder pad rests comfortably on
the off-side shoulder and the cutting
path of the blade is parallel to the
ground. Make sure all hooks and
adjustment devices are secure.
Optional
Brushcutter Harness
A harness provides additional protec-
tion against blade thrust. In addi-
tion, a harness gives significant
support and comfort to help ensure
safe and efficient operation.
WARNING!
Always wear a shoulder
strap when operating this
unit with a blade. A shoulder strap is
also recommended when using
trimmer line.
WARNING!
A cutting attachment shield
or other protective device
is no guarantee of protection against
ricochet. YOU MUST ALWAYS
GUARD AGAINST FLYING DEBRIS!
WARNING!
NEVER use any cutting
attachments which are not
recommended in this manual. Using
non-recommended cutting attach-
ment may result in serious injury.
WARNING!
When using a trimmer
head, make sure each of
the line lengths are no longer than 15
cm. Using a trimmer head with lines
longer than 15 cm may damage the
machine.
7 Unit Condition Check
NEVER operate the unit with the
cutting attachment shield or other
protection devices (strap, blade
retention clip, etc.) removed.
Use only authorized Shindaiwa
parts and accessories with this
machine. Do not make modifica-
tions to the machine without the
written approval of Shindaiwa.
ALWAYS make sure the cutting
attachment is properly installed
and firmly tightened before opera-
tion.
NEVER use a cracked or warped
cutting attachment: replace it with
a serviceable one.
ALWAYS make sure the cutting
attachment fits properly into the
appropriate cutter holder. If a
properly installed attachment
vibrates, replace the attachment
with new one and recheck.
ALWAYS stop the engine immedi-
ately and check for damage if you
strike a foreign object or if the
machine becomes tangled. Do not
operate with broken or damaged
equipment.
NEVER operate a machine with
worn or damaged fasteners or
attachment holders.
NEVER cut with dull blades. Doing
so will increase the risk of blade
thrust and may also damage your
equipment.
IMPORTANT!
When operating a brushcutter, make
sure both the handle and harness are
adjusted to the size of the operator using
the machine.
NOTE:
Although a shoulder strap accessory is not
required for use with a grass trimmer, a
shoulder strap can increase operator
comfort during extended periods of
operation.
NOTE:
Using a shoulder strap when operating
this unit with a blade allows you to
maintain proper control of the unit and
reduces fatigue during extended opera-
tion.
8-1 Engine Operating Speeds
Operate the engine at full throttle
while cutting. Best fuel efficiency is
obtained by releasing the throttle
when swinging back after a cut.
■To prevent possible engine dam-
age, do not allow the trimmer or
brushcutter to run at high speeds
without a load.
■Avoid operating the attachment 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 attachment.

9 Blades
CAUTION!
Operation of trimmer without a cutting
attachment shield and using exces-
sive line length can lead to premature
clutch failure.
Your Shindaiwa F220/T220/C220

Do not push the rotating line into trees,
wire fences or any material that could
tangle or break the nylon lines.
Engine Operating Speeds
Operate the unit at full throttle while
cutting grass.
CAUTION!
Operation at low rpm can lead to
premature clutch failure.
Hold the grass trimmer as shown in
the illustrations. The trimmer head
should be angled slightly into the area
to be cut. To ensure maximum trim-
mer-line service life, cut only with the
tip of the trimmer line. Sweep the
trimmer head left to right (T220-
C220), and right to left (F220) to trim
the grass. During cutting operations,
the trimmer head should be kept
horizontal to the ground at all times.

WARNING!
nBefore working with a blade-
equipped unit, always inspect and
clean the area of objects that could
interfere with or damage the blade.
nNever use a blade near sidewalks,
fence posts, buildings or other
objects that could cause injury or
damage.
nNever use a blade for purposes
other than those for which it was
designed.
nWhenever 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!
nA blade-equipped unit must be
equipped with a bicycle-type
handlebar or barrier bar as well as
a harness or shoulder strap.
nAlways make sure the cutting
attachment shield is properly
installed before operating
this unit.
9-1 Using a Blade
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 handlebar or barrier
bar helps prevent the operator from
moving forward, or the unit moving
rearward, thus preventing inadvert-
ent 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. In
addition, a shoulder strap gives
significant support and comfort to
help ensure safe and efficient opera-
tion.
When operating a unit with a
blade, make sure both the handle
and shoulder strap are adjusted to
the size of the operator using the
unit.

Cutting Attachment
9-1 Using a Blade (Cont.)
The blade rotates counter-clockwise.
For best performance and to mini-
mize being stuck by debris, move the
blade from right to left while advanc-
ing 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 posi-
tions.
WARNING!
When cutting wood with a saw, feed
the blade slowly—never strike or
“slam” a spinning blade against
the wood.
WARNING!
DO NOT use 2-tooth or non-Shin-
daiwa approved 4-tooth cutting
blades with Shindaiwa trimmers and
brushcutters.
Vertical Cuts
Hold the brushcutter with the blade at
a 900angle 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.

WARNING!
Before performing any
maintenance, repair, or
cleaning work on the machine, make
sure the engine and cutting attachment
are completely stopped. Disconnect
the spark plug wire before performing
service or maintenance work.
WARNING!
Never repair a damaged
blade by welding,
straightening, or by modifying its
shape. An altered blade may break
during operation, resulting in serious
personal injury.
Prior to each work day, perform the
following:
■Remove the dirt and debris
from the engine, check the
cooling fins and air cleaner
for clogging, and clean them
as necessary.
■Carefully remove any
accumulations of dirt or
debris from the muffler and
fuel tank. Dirt buildup in
these areas can lead to
engine overheating, fire, or
premature wear.
■Check for loose or missing
screws or components. Make
sure the cutting attachment
is securely fastened.
■Check the machine for
leaking fuel or grease.

carbon deposits lodged in the
muffler’s spark arrester screen.
In such cases, performance can
usually be restored by removing the
spark arrester screen and giving it a
thorough cleaning with a stiff bristle
brush.
If carbon deposits are severe or if
no performance improvement is
noted, your 220 unit should be
returned to your Shindaiwa dealer
for inspection.
WARNING!
Never operate this unit with
a damaged or missing
muffler or spark arrester! Operating
with missing or damaged exhaust
components is a fire hazard and
may also damage your hearing.
■Remove the spark plug and pour
about 1/4 ounce of oil into the
cylinder through the spark plug
hole. Slowly pull the recoil starter
2 or 3 times so oil will evenly coat
the interior of the engine.
Reinstall the spark plug.
■Before storing the machine,
repair or replace any worn or
damaged parts.
■Remove the air cleaner element
from the carburetor and clean it
thoroughly with mixed fuel.
Squeeze out the fuel and
reassemble the element.
