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 handle-

bar or barrier bar as well as a har-

ness or shoulder strap.

n

  Always make sure the cutting at-

tachment shield is properly installed 

before operating this unit.

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 HANDLE-

BAR OR BARRIER BAR SECURELY IN 

PLACE ON THE UNIT!
Brushcutter Shoulder Strap
A shoulder strap provides additional protec-

tion against blade thrust. In addition, a 

shoulder strap gives significant support 

and comfort to help ensure safe and ef-

ficient operation. When operating a C3410 

with a blade, make sure both the handle 

and shoulder strap are adjusted to the size 

of the operator 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.
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 op-

eration 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 

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.

When cutting wood with a saw, feed  

the blade slowly—never strike or “slam” 

a spinning blade against the wood.

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. 

When making vertical cuts, never allow 

the blade to exceed waist height.
