 4. Safety precautions

product onto the ground in a flat 
clear area and hold it firmly in 
place so as to ensure that neither 
the cutting part nor the throttle 
lever come into contact with any 
obstacle when the engine starts.

WARNING

Never place the throttle lever into 
the  high-speed  position  when 
starting the engine.

3. After starting the engine, check 

to make sure that the cutting at-
tachment stops rotating when the 
throttle is moved fully back to its 
original position. If it continues to 
rotate even after the throttle lever 
has been moved fully back, turn 
off the engine and take the unit to 
your authorized ZENOAH servic-
ing dealer for repair.

 USING THE PRODUCT

IMPORTANT

Cut only materials recommended by 
the manufacturer. And use only for 
tasks explained in the manual. 

1.  Grip the handles firmly with both 

hands using your whole hand. 
Place your feet slightly apart 
(slightly further apart than the 
width of your shoulders) so that 
your weight is distributed evenly 
across both legs, and always be 
sure to maintain a steady, even 
posture while working.

2. Keep cutting attachment below 

waist level. 

3.  Maintain the speed of the engine 

at the level required to perform 
cutting work, and never raise the 
speed of the engine above the 
level necessary.

4. If the unit starts to shake or vi-

brate, turn off the engine and 
check the whole unit. Do not use 
it until the trouble has been prop-
erly corrected.

5.  Keep all parts of your body away 

from rotating cutting attachment 
and hot surfaces.

6. Never touch the muffler, spark 

plug, or other metallic parts of the 
engine while the engine is in op-
eration or immediately after shut-

tions as to sound level and hours of 
operations for the product.

  BEFORE STARTING THE 

ENGINE

1.  The area within a perimeter of 15 

m of the person using the product 
should be considered a hazard-
ous area into which no one should 
enter. If necessary, yellow warn-
ing rope, warning signs should 
be placed around the perimeter 
of the area. When work is to be 
performed simultaneously by two 
or more persons, care should also 
be taken to constantly look around 
or otherwise check for the pres-
ence and locations of other 
people working so as to maintain 
a distance between each person 
sufficient to ensure safety.

2. Check the condition of working 

area to avoid any accident by 
hitting hidden obstacles such as 
stumps, stones, cans, or broken 
glass.

IMPORTANT

Remove any obstacle before begin-
ning work.

3. Inspect the entire unit for loose 

fasteners and fuel leakage. Make 
sure that the cutting attachment 
is properly installed and securely 
fastened. 

4. Be sure the cutting attachment 

guard is firmly attached in place. 

5. Always use the harness. Adjust 

the harness for comfort before 
starting the engine. The harness 
should be adjusted so the left 
hand can comfortably hold the 
handlebar grip approximately 
waist high.

 STARTING THE ENGINE

1.  Keep bystanders and animals at 

least 15 m away from the operat-
ing point. If you are approached, 
immediately stop the engine. 

2. The product is equipped with a 

centrifugal clutch mechanism, so 
the cutting attachment begins to 
rotate as soon as the engine is 
started by putting the throttle le-
ver into the start position. When 
starting the engine, place the
