Warning on Use, Installation, and Operation!
(Safety Precautions)
● The blade of Komatsu-Zenoah’s brushcutter is a safe product manufactured with its own
specifications. Before using it, read the following matters well, and follow them to prevent
accidents.
● Before using this product, make sure there is no broken or cracked part of the blade.
● Never use a blade that is broken, deformed, or worn down. Use Zenoah’s genuine blades.
● Two-tooth blades are very dangerous, and could cause a serious injury. Try to avoid
using them.
● If the blade hits stone, concrete, metal, or any other object, it could cause serious injury
to the user of this product or people nearby. Be careful to avoid such objects. If the
product does hit an object, stop work immediately and check the blade thoroughly.
● When storing the machine, put the cover on the blade. When using the machine, always
keep the safety guard installed.
● Install the blade correctly, and make sure the connecting pin in the blade does not come
out of place.
● Cut branches of soft trees; do not cut hard trees.
● If abnormal or unusual vibration occurs, stop work immediately and check the blade.
● Do not use this blade for any other manufacturer’s grass-cutter.
● While using this machine, prevent any person or animal from accessing the area within
15 m of the machine.
● Be sure to wear protective gear when using the machine.
● When replacing the blade,
1) Make the lower part of the blade edges round. Otherwise, the blade edges could chip
off.
2) An unbalance blade increases the vibration of the machine. Make sure the blade is not
unbalanced.
3) Note that the blade becomes hot. When the blade becomes hot, cool it in air gradually.
Cooling it with water might cause invisible cracks.
● For details of the kind, specifications, material name, and other instructions for the blade,
