2. Starting
FOLLOW THE SAFETY RULES
persons present on the site should never stand close to the working area and especially not in the path of any material that could be thrown off by the rotor.
It is preferable that a new driver should already be used to driving the carrier vehicle, and that he should choose a piece of clear, flat ground without obstacles, to concentrate on operating the side-arm flail mower.
2 1 .Starting .the .rotor .(carrier .vehicle .stopped)On a Noremat machine : - Engage the PTO. - Extend the arm and place the mowing head on the ground. - Raise the vehicle engine speed to the selected PTO speed – approx. 500 rpm. - Select the direction of rotation of the rotor.
Allow the machine to run at the speed recommended (500rpm) by your NOREMAT technician for several minutes. This is very important in temperatures of less than 5 degrees C.
- INCREASE THE VEHICLE ENGINE SPEED PROGRESSIVELY to the selected PTO speed.
On other makes of machine :
- Refer to the operator’s manual provided with the machine.
- Allow the rotor to rotate at the recommended speed (500 rpm) for a few minutes, especially if the temperature is below 5°C.
- INCREASE THE VEHICLE ENGINE SPEED PROGRESSIVELY to the selected PTO speed...
No warranty claim will be accepted for the hydraulic components if this procedure is not respected.
2 2 .Stopping .the .rotorOn a Noremat machine :- Stop the rotor.
- Decrease engine speed by approximately 500 rpm.
It is essential to stop the rotor before stopping the PTO shaft
On other makes of machine :
- Refer to the operator’s manual provided with the machine.
No warranty claim will be accepted for the hydraulic components if this procedure is not respected.

USER’S MANUAL1. Safety instructions
Read this paragraph before operating your side-arm flailmower.
- Make sure that the operator is familiar with the operation of the tractor / machine combination.
- The two have to be operated simultaneously, and that requires practice.
- If this is not the case, the operator should choose a piece of flat ground without obstacles or people on it, to practise.
- Never start the machine and the mowing head if they are not in working order from the safety point of view, and especially if the safety covers are not in place.
- When using the machine for mowing (i.e. with the rotor turning in the opposite direction to the tractor wheels) it is essential that the baffle be fitted to prevent the rotor throwing material out.
- Never leave the rotor turning if a person could be in the path of any material that could be thrown off by the rotor.
- Never move the arms of the machine if anyone could be inside the machine operating area.
- Never remain under the machine.
- Never insert branches or objects by hand during operation.
- Only work with a good light; natural or artificial.
- Never work in an explosive or easily inflammable
atmosphere.
- Always make sure a hydraulic component is not under pressure before removing it.
- Check for foreign matter in the unions.
BEFORE DOING ANY WORK ON THE MACHINE :
- Place the mowing head on the ground.
- Make sure that the control lever is in neutral.
- Disengage the tractor PTO.
- Stop the carrier vehicle.
- Put the gear lever in neutral.
- Make sure that the hydraulic components are not under pressure.

2. USER’S RESPONSIBILITY
The user is responsible for the strict observance of working standards, and safety and maintenance instructions as explained in this manual.
We advise you to read this manual completely before doing any work with your mowing head.
- Any modifications made to the mowing head are the sole responsibility of the person doing them.
- When using the machine for mowing (i.e. with the rotor turning in the opposite direction to the tractor wheels) it is essential that the front hood be fitted to prevent the rotor throwing material out.
hood and flaps
If these regulations are not respected, responsibility lies with the user alone.

3. Operation3 1 .Choice .of .the .working .ground .speedChoose an appropriate vehicle speed for the vegetation being cut, while maintaining an engine speed to give a rotor speed of 3000 rpm max. - Insufficient rotor speed is detrimental to vegetation cutting. - Increasing the speed could result in overheating of the circuit and premature wear of the hydraulic components. The rotor speed should never fall while working. If there is an obstacle in the rotor’s path, stop the rotor, stop the vehicle and raise the cutting head.
The danger from material thrown out from the cutting head is increased. Reduce the vehicle speed in the following situations: - When working at maximum outreach.
- On uneven ground.
- If the vegetation is particularly dense.
- On a new site.
3 2 .VibrationMake sure that the cutting head does not start vibrating. Possible causes are: - Flails excessively worn, broken or missing. - Mass of vegetation in the blade recess. - Rotor damaged by a major impact.
All these causes may result in imbalance of the weight rotating with possible detrimental consequences for the whole of the machine, such as : loss of bolts, or even in the long term breakage of fabricated parts (weld failure, part breakage, etc.).
- Daily checks: - state of wear of the accessories and cutting tools, - tightness of rotor bolts and bolts, - flail and rotor bearing at the torque indicated on page 10.
3 3 .Working .on .the .groundThe mowing head should “brush” the ground but not rest on the roller serving as a probe for movement control.
Take care that that the mowing head does not catch on obstacles such as boundary stones, rocks, tree stumps, etc.....
The rotor rotates in the opposite direction to the carrier vehicle wheels (clockwise when viewed from the cab).
The mowing head must be fitted with its guarding cover to prevent material being thrown out.
3 4 .High .workingStart cutting from the top so that the branches, that are cut but not yet chipped, are picked up from the ground during subsequent passes. This method is essential to obtain a clean job. The branches that fall to the ground are chipped more easily if they are presented perpendicularly to the rotor. This is especially true for the biggest ones (3 cm + in diameter / 1 ¼ inches). The rotor rotates in the same direction as the carrier vehicle wheels (anti-clockwise when viewed from the cab).
For this operation the guarding cover must be removed from the mowing head.

5. Greasing5 1 .Recommendations .about .greasingGreasing is an essential part of the maintenance of your machine.
The guarantee of long service life and correct operation depends on strict observance of the greasing intervals.
It is essential to use good quality grease.
We recommend that you use a Multi-purpose Extreme Pressure grease of type L-XBDH2 (Conforming to ISO specification standard 6743-9, alternatively KP2K-25 conforming to DIN 51502 standard).NOREMAT ref 102475
Before every greasing operation, makes sure that the grease gun head and the grease nipple are in good condition and clean.
Greasing comes under the category of work on the machine. Observe the safety rules.
1 Rotor bearing X 8g2 Probe roller bearing X 8g3 Fixed bearing bearing X 8g
*2 grease gun doses (dose of grease injected is estimated as approx. 4 grams per stoke).

6. Maintenance6 1 .Rotor .replacement
As for all work, observe the safety instructions.
Place the mowing head on the ground.
Remove the baffle plate.
Lower the mowing head onto the ground (resting on the transmission casing side).
Lock the rotor using the notches in the shaft end and remove the four bolts holding the rotor.
Loosen the 3 bearing bolts.
Hold the rotor before removing the 3 bolts from the bearing. The rotor can now be removed.
Repeat the operations in the reverse order to fit the new rotor.
Line up the centring pin with one of the holes in the rotor drive flange.
We recommend replacing the nuts, bolts and bolts every time a rotor is replaced.
Never operate the hydraulic motor while the rotor is removed.
To facilitate the replacement of rotors, we recommend fitting each one with a bearing (part no. 113739).
6 2 .Mowing .head .maintenanceCheck regularly : - The state of wear of the accessories and cutting tools, the torque of the rotor bolts, the attachments of the flails and the rotor bearing, the condition of the front and rear flaps and the general condition of the mowing head. -Respect the lubrication intervals.
Timely replacement of worn parts ensures adherence to safety standards and prolongs the service life of the mowing head.
6 3 .Storage- Clean the mowing head. - Choose a clean and dry place for removing the machine. - Grease the mowing head completely. - Check that there is no foreign matter in the unions and then plug the hydraulic motor.
The service life of the machine depends on the cleanliness of the hydraulic circuit.
