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 at-
tachment shield is properly installed 
before operating this unit.
Using a Blade C242
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 C242 with a blade, make 
sure both the handle and shoulder strap 
are adjusted to the size of the operator us-
ing 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  
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.
