7. Safety Precautions
• Hold the machine securely with both hands. Grip the
control handle with your right hand; grip the other handle
with your left hand.
• To maintain a stable posture, adopt a stance wider than
shoulder width.
• Maintain a firm footing.
• Shut off the engine if abnormal noise or vibration occurs,
if an emergency occurs, or when putting down the
machine.
• If someone calls out or otherwise interrupts you while
working, always shut off the engine before turning around.
8. Special precautions when two or more
machines are in use
When two or more machines are in use simultaneously, it
is essential that all operators use extreme care to maintain
a safe distance from each other, constantly look around,
and always remain aware of presence of the other
operators to ensure safe operation.
9. Blade thrust
If a running blade hits a hard stationary object such as a
tree, rock, or wall, the cutting blade can kick back
violently in a phenomenon known as blade thrust. When
blade thrust occurs, the reaction can swing the cutting
blade violently in an unexpected direction, creating a high
risk of injury. To avoid blade thrust, strictly observe the
following:
• Before starting work, check for hard stationary objects
such as trees, rocks, or walls that can cause blade thrust.
Mark any hard stationary objects so that the operator can
avoid them.
• Do not use an excessively dull cutting blade.
10. Cutting pattern
MODEL: MT23HM/B
• The cutting attachments of the line trimmer rotate
clockwise. Cut a 1.5-meter arc from left to right. Within
this arc, maintain the cutting device at a consistent height
above the ground. Advance slowly and gradually,
beginning with the left foot.
• Cut brush with the arc on the cutting device. If the
arc on the rotating device hits a solid object, a cutting
device running at high speed will thrust toward the
operator, creating a very dangerous situation. (Fig.3-4)
MODEL: Other than MT23HM/B
• The cutting attachments of the brushcutter rotate
counterclockwise. Cut a 1.5-meter arc from right to left.
Within this arc, maintain the cutting blade at a consistent
height above the ground. Advance slowly and gradually,
beginning with the right foot.
• Cut brush with the arc on the cutting blade. If the
arc on the rotating blade hits a solid object, a cutting
blade running at high speed will thrust toward the
operator, creating a very dangerous situation. (Fig.3-5)
11. Abnormal noise and vibration
• If the machine suddenly exhibits abnormal noise or
vibration, immediately shut off the engine.
• Possible causes of sudden noise or vibration include
loose screws and damage to the cutting blade or other
components. Check the entire machine for any sign of a
problem.
• After the cause has been found, do not use the machine
until you have completed the repair.
