carefully to learn how to operate the machine safely and how
to set it to provide maximum field efficiency.
3.1 Checking Before Operating
ATTENTION: Only use universal joint conforming to CE standard and
protect them properly.
Before operating the machine, the following areas should be checked off:
1. Pay attention to the warning stickers on each greasing point. Before starting the
machine, please make sure lubricate each grease point with grease or oil
according to requirement on the warning stickers.
2. Use only an agricultural tractor of horsepower within limits of the machine specified.
3. Check that the machine is properly attached to the tractor. Be sure retainers are used
on the mounting pins.
4. Be sure extra weights are mounted on the front of the tractor.
5. Check the oil level in the gearbox. Add as required.
6. Check that the tractor PTO shaft turns freely and that the machine driving shaft can
telescope easily.
7. Check the blades. Be sure they are not damaged or broken and swing freely in their
mount. Repair or replace as required.
8. Check and tighten the blade bolts.
9. Check for entangled material in all rotating parts. Remove this material.
10. Install and secure all guards, doors and covers before starting.
11. Before installing the universal joint, the tractor and the machine motor shall be
stopped and the key be taken away. The universal joints shall be installed in good
state, with proper protective parts.
12. The chain on the protective parts of the universal joint shall be guaranteed in good
condition, in case, automatic rotation occurs.

again through the frame to protect the joint from damaging.
16. Don’t approach the machine when the machine runs.
3.2 Adjusting the Height
In order to conduct a precise work, the machine shall be operated according to the
recommended cutting height.
For saving fuel and power, and reducing the wear of the machine, the cutting height must

7
be regulated correctly.
When regulating the working height, loosen the screw (1), remove the screws (2) on both
sides; regulate the roller height (see following drawing); fix the parts on the set position.
The lowest hole is the highest working height; put the screws (2) into the set hole; tighten
screw (1) and screws (2).
3.3 Regulating the Tension of Driving Belt
ATTENTION: The machine shall always stand still for regulating the
tension.
Remove the driving belt

The recommended moving forward speed is 1.5
km/h, according to the grass height, thickness
and working condition.
The driving belts are tightened by hand at the
regulating point B up to the correct tension.
Tighten all screws after regulating.
The driving belts shall be replaced when they are
not in a good condition.

Position Moving
Position
In order to keep the machine stable, install the supporting frame on the machine when the
machine is stopped (see above drawing).
ATTENTION: When transferring the moving state of the machine to the
working state, do not stand between the machine and the
tractor.
The machine coupling is equipped with 3 pins so that the machine can be coupled with all
tractors with universal coupling with 3 pins. Each telescopic pole on the machine can be
adjusted properly according to the type of the tractor. Keep the Flail mower away the
tractor with a certain distance. The universal joint shall be tense and the largest distance
in the closed state shall be 5/10 cm.
Moving the lifting arm, and putting it between axes, insert the joint pins and fix them with
pins. Fix the lifting arm with chain and tensioning device so as to prevent lateral
movement of the machine. Connect the universal joint to the PTO shaft of the tractor on
the side of the tractor. In any event, it cannot produce a collision in any position. While
connecting 3 points, pay attention to that the PTO shaft of the tractor shall be parallel with
the ground. It is very important to keep the machine driving axle and the PTO shaft of the
tractor in parallel.
The machine shall be lifted from the ground before moving the machine.
