WARNING!

Before working with a blade-

equipped unit, always inspect and

clean the area of objects that could

interfere with or damage the blade.

Never use a blade near sidewalks,

fence posts, buildings or other

objects that could cause injury or

damage.

Never use a blade for purposes

other than those for which it was

designed.

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!

A blade-equipped unit must be

equipped with a bicycle-type

handlebar or barrier bar as well

as a harness or shoulder strap.

Always make sure the cutting at-

tachment shield is properly installed

before operating this unit.

Using a Blade C3410

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 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. In addition,

a shoulder strap gives significant support

and comfort to help ensure safe and

efficient operation.

When operating a C3410 with a blade,

make sure both the handle and shoulder

strap are adjusted to the size of the opera-

tor using the unit.

Engine Operating Speeds

Operate the unit at full throttle while cut-

ting. Best fuel efficiency is obtained by

releasing the throttle when swinging back

after a cut.

To prevent possible engine damage, do

not allow the brushcutter to run at high

speeds without a load.

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.

The blade rotates counter-clockwise. For

best performance and to minimize being

stuck by debris, move the blade from right

to left while advancing on your work.

Position the blade so cuts are made be-

tween 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.

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-Shindaiwa

approved 4-tooth cutting blades with

Shindaiwa trimmers and brushcutters.

Vertical Cuts

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.
