4.4 Precautions for Operation
When operating the brush cutter, observe the following as well as “1.2 General Precautions”.
■ General
● If you feel tired during operation, be sure to take a break. If you continue operating without taking a
break, the brush cutter could be out of control. Or if you are aggravated by strenuous work, consult a
physician (doctor) before operating the brush cutter.
● The brush cutter is not insulated against electric shock. Have a person qualified for electric work remove
wires and cables which can be removed. If there are still wires or cables not removable, do not operate
the brush cutter.
● Do not cut any materials other than grasses, weeds and shrubs.
● Do not rotate the nylon cutter at more than 10,000 r/min.
● Keep the nylon cutter from hitting hard foreign matters such as rocks, concrete, tree stub and bottle etc.
● When using the iron blade (option), avoid stones and stumps. They could bounce back, or the iron blade
(option) edge and stones, etc. could be scattered, resulting in injury.
■ Check of Brush cutter
● Make sure that the blade guard is securely installed to the appropriate position before starting the
operation.
● For iron blade (option), be sure to use the sufficiently ground iron blade (option). After grinding, be sure
to check if the iron blade (option) is well-balanced.
● Make sure that an appropriate blade guard is installed.
■ Check of Work Area
● Check if there is no hard object such as metal shard which could damage the cutting part in the work
area before starting operation. Pay attention when operating the brush cutter near fences or poles.
● Keep it away from fence edges, cliffs and hard objects.
● Take extreme care when operating in a slippery place. Also watch out for rough ground, stumps, roots,
ditches or holes which could cause you to trip or stumble. Do not use the brush cutter when it is raining.
● To prevent fire disaster, do not use the brush cutter in a place where there are organic sediments, fallen
leaves or excessive lubricants.
■ In Emergency
● If the cutting part is contacted with obstructions, immediately stop the engine. After the cutting part
is completely stopped, check if the cutting part is not broken, bent or cracked. If there is any failure,
replace the cutting part.
Also, check if the shaft tube is not bent, broken or cracked. If there is any failure, contact the sales
agency.
● When removing the foreign objects wound around the cutting part, gear case or blade guard, be sure
to stop the engine with the stop switch. Do not place your hands, etc. close to the cutting part while the
engine is operating even if the cutting part is not rotating. When the throttle cable is gripped accidentally,
the cutting part will suddenly start rotating, causing serious injury.
