Unit 1, start, should first engage the power output shaft power, and then hang work gear, the clutch slowly, at the same time control hydraulic lifting handle or a lifting device, so that the rotary tiller  blade is buried, then increase the throttle, until the normal depth. The absolute prohibition of the rotary cultivator falls on the ground suddenly with soil fertility, or the rotary cultivator plummeted to be buried, or make the blade, the knife shaft under impact load, and leads to the cultivator and tractor transmission parts damaged.

2, listen to the working parts in operation with or without noise and metal percussion sound, if any should immediately stop checking, troubleshooting before it can continue to work.

In 3, when the rotary too deep, heavy clay soil or excellent, tractor black smoke with skid phenomenon, should be appropriate to reduce the depth or reduce the tilling amplitude, or hung low.

In 4, when turning, should reduce the throttle, tail wheel and the steering clutch should cooperate with each other, slowly, no sharp turns, to prevent damage to the parts. Wheel type tractor turning or backing, should rise to anti twist blade, rotary cultivator, twisted the knife shaft.

5, through groove ridge, the rotary operating handle on the separation position, so as to avoid the rear part of the tractor suddenly tilted, blade.

In 6, the timely removal of the knife shaft, blades of grass twining, to avoid damaging the knife shaft, effect of deep tillage. Removal of winding grass must turn off the engine.

In 7, when the universal joint works ends should be close to the level, its angle not larger than 10 degrees, in the state of ascension, angle not larger than 30 degrees, at the same time should reduce speed, to prevent damage to the gimbal assembly.

In 8, operation, rotary machine and machine is strictly prohibited to stand on, to prevent the occurrence of danger.

9, every 3～ after 4 hours, should be down to check the blade without loosing, deformation, abnormal, should be screwed or replacement.

10, check and remove the faults, must turn off the engine, in order to ensure the personal safety.

11, farmland transfer, should promote rotary cultivator, and cut off the power output shaft power. If the transfer distance of the locking device of rotary cultivator, applications will be fixed at a certain position, or remove cardan transfer.

In 12, park, should make the rotary cultivator with no suspension, park. The use of the maintenance after end of job needs to be deposited for a long time, should be removed, washed mud rotary tiller appearance, winding grass, to replace the drive gears in the oil, to each lubricating part lubrication; remove the blade, universal joints and greased is placed in the room; on the other exposed parts oiler, timely repair or replacement of damaged parts, then the pad rotary cultivator, exists in the light, rain, dry and ventilated places.
