12. Operations
12-1. Precautions before Operation
• Do not operate the machine in places in danger of a land subsidence or landslide.
• The machine may overturn on a slope with an irregular surface. Do operate use the
machine in such a place.
• Avoid operation on slopes.
• The machine is in danger of slipping and overturning on a wet slope. Do not operate the
machine in such a condition.
• Check to see if someone is playing in the vicinity. There is a possibility of getting struck
with a hit ball.
• Check the surroundings for safety (front, back, right, and left, as well as trees, ditches,
irregular surface of the green, sprinklers, and cups etc.) during operation. Operate the
machine at an appropriate speed so that you can stop the machine any time in an
emergency. Avoid sudden acceleration, sudden braking, and abrupt steering. Drive the
machine slowly especially when descending a slope.
• When the machine is attached, the total length of tractor will increase. Be careful of the
people and objects around the machine when turning the machine.
• Do not touch the tines, crank, and other moving sections when the machine is in
operation, otherwise your fingers or hands may get injured.
• Do not operate the machine at night time or in bad weather when the visibility is poor.
• When abnormal vibration, abnormal sound (wire or vinyl coiling tangled in the tines), or
other anomaly occurs in the machine during work, stop the engine immediately and
investigate into the cause. Completely repair the machine before operating it again.
• When colliding with some obstacle, stop the tractor engine and check up whether
respective parts are not damaged.
• Remove stone, wire, sticks, and other obstacles before work, otherwise not only
machine trouble but also an accident due to the scattering of such objects may result.
• When leaving the machine, park the machine on a flat ground, stop the tractor engine
and remove the key. Be sure to apply the parking brake and chock the tires.
Lower the attached machine with care so that the tines cannot touch the ground.
