to in the original location.
2. Fixed coupling plastic cover
⚠Danger
● If you use no plastic cover to protect the coupling, it is possible to be involved in the occurrence of
injuries. Do not use no plastic casing coupling.
● If you use damaged couplings, injuries may occur entangled.
Couplings if damaged, replace it immediately. Please check if coupling have damage before using.
● When connected to the tractor and rotary hoe, as a third party do not pay attention, inadvertently let
the power output shaft rotation, injuries may occur, after you cut off the power and stop the tractor
engine PTO can be connected to the tractor.

www.tmgindustrial.com 17/35 Toll Free:1-877-761-2819
3. After connection, fixed the chain to prevent the plastic cover rotation
4. Max rotation angle of coupling
⚠Noted !
If the shaft beyond its maximum operating angle of rotation at work, there will be unexpected
injury accident. Be sure to fix the tractor three-point suspension before use.
4. Coupling lubrication and maintenance
Proper grease lubrication and maintenance will greatly enhance the transmission efficiency of the
tractor.
After eight hours of continuous operation coupling, check above the pointed position
should be oiling and lubrication.

CHECK BEFORE OPERATING
1. Check before operating
1. Check the various parts of the tractor
Please check the parts according to the manual
2. Check the connection site
(1) Fix connection pin of three-point suspension
(2) Check the stand foot retract
3. Check the coupling
(1) Whether the coupling ends effectively connected with the machine and tractor
(2) Security chain is valid is fixed.
(3) Plastic protective cover is complete.
(4) Security chain sag length is appropriate.
4. Rotary tiller machine inspection
(1) The cutter blade bolts are tightened.
(2) Whether the gearbox rotation is normal, the hydraulic oil in gearbox not exceed the volume of 1/3,
if less need to add gear oil.
(3) The various parts of the bolts and nuts are tightened.
(4) The oil in each parts should be adequ
2.Check during engine starting
1. Check the drive system
The new machine or machine long unused, you must first idling operation.
(1) Start the tractor engine and low speed transfer to PTO.
(2) The engine speed was adjusted to 1000 rev / min mode, idling about 5 minutes.
(3) if the above normal, the rotational speed was adjusted to 500-540 rev / min mode, idle for about
5 minutes.
If the drive system has a problem, you can refer tractor manual investigation.
2. Check the tractor hydraulic system
Operate tractor three-point suspension lift handle and hydraulic output handle, lifting and turning the
machine to ensure no problems.
If you have questions, please contact the tractor dealer.
⚠Danger
● If start the engine when the PTO does not cut off the power ,it may cause harm to the people around.
Always switch off the PTO and then start the engine.
● When starting the engine, if it does not lower the rotary tiller is approaching, has no intention of falling or
rising, people around may cause injury. Keep machine is approaching low before starting the engine.

OPERATING ESSENTIALS
1. Attentions during in use
1. When start job, lift the rotary tiller, make sure accelerate the blade axle to the rated speed, and then drop the
tiller until the blade buried to the desired depth. Do not accelerate the shaft or drop the tiller after buried the
blade, to avoid overloading the tractor or damaging the blades.
2. Within the job, should try to drive slowly, so that can guarantee the work quality, crushing clouds and reduce
mechanical wear and tear, pay attention to whether there is any noise or metal percussion sounds, and
observe the pulverizes, deep tillage situations, if there is any exception should immediately stop work and
check, after the exclusion can continue operations.
3. Stop work when turn a corner, raise the tiller until the blade off the ground, and reduce tractor throttle to
avoid damage to the blade. When raise rotary tiller, make sure the universal -joint tile angle less than 30
degrees, it may cause noise if over the degrees and then premature wear or damage
4. When drive in reverse, crossing the ridge and transfer to other land, should raise the tiller to the highest
position, and cut off the power to avoid any damages, if more to far away , make sure to use lock device fix
the machine well.
5. After working, should maintenance the machine, remove dirt and debris, check the connection fastening
case, each point lubricant filling oil, to prevent aggravating wear.
2. Rotary tiller adjustment
1. Side adjustment, park the tractor with rotary hoe in flat ground, drop the rotary hoe until the blade 5cm
from the ground, check the the tip for sides blades have the same distance to ground, in order to
ensure the blade axle in straight level, tillage depth evenly.
2. Front and rear adjustment. When drop the rotary tiller to the required depth, observe universal joint
angle and the rotary tiller angle is in a near horizontal position. If the angle is too large, adjust the rod,
so that rotary hoe in the horizontal position.
3. Lifting height adjustment. Rotary job, angle does not allow more than 10 degrees, When drive in
reverse, the angles are not allowed more than 30 degrees. Pay special attention when lifting. For
increased again rotary tiller, the universal joint power should be removed.
⚠Danger
● Don't touch blade when in operation, injuries may occur.
● In high-speed rotating operation, the stone will fly out, take close attention to yourself and the problem
around.
⚠Warning
● Exceed the PTO speed may cause injury accident, make sure to operate within the specified speed.
● Keep low-speed operation in tilt ground.
Note the front and surroundings while driving,
