Product Description
The NIKO Combination Mulcher KM is used in winemaking and forestry to mulch grass and wood cuttings
and in municipal areas for hedge cutting and trimming undergrowth. The device is very robust and can be
used for various purposes.
1. Designated Use
The combination mulcher is exclusively designated for:
-The mulching of grass and wood cuttings
The machine is not designated for other types of uses – these will be deemed to be improper uses! We
expressly indicate that large pieces of wood, stones and other similar objects be removed from the
work area.

3. Function Description
Attachment to the basic device takes place via the 3-point intake with two quick locks and a bolt on the
hydraulic cylinder for lifting the device. The throttle is attached to the space provided on the handlebars of the
bulldozer. In doing so, it must be ensure that the Bowden cable is not bent or jammed.
The cutting quality of the combination mulcher mounted on the bulldozer is dependent upon the travelling
speed, the height and density of the object being cut as well as the condition of the cutting tools. Dependent
upon the conditions of these parameters, the working speed amounts to approximately 4 -6 km/h and
approximately 2 -4 km/h for the cutting of wood.
In order to work with the mulching device, the gasoline motor/oil motor will be started in accordance with the
directions in the motor manual provided.
Gasoline Motor:Fill with normal gasoline
Check the oil level
Open the gas valve
Set throttle to “fully open"
Closer the start flap [only if the motor is cold]
Pull out starter until resistance can be felt
Start the motor with a short, strong jerk.
Slowly close the starter flap.
Oil Motor: The oil motor is turned on using the 3-way valve.
WARNING: Only start the 3-way valve when the device is running!!!
Check the hydraulic hoses to be sure they are tightly sealed
Do not leave the oil motor standing in direct sunlight when decoupling!!!
WARNING:
No objects can be located under the mulcher while it is being started
(Stones, wood, et cetera).
Stand to the side of the device when starting it. Keep a sufficient distance away
and be particularly sure that your feet are not underneath the mower housing.
The cutting height can be adjusted via the undercarriage disc on the guide wheel of the mulcher (never do so
while the motor is running!!!).
To mulch grass, the teeth behind the mower housing must be removed (maximum grass throughput).
The mulching device is lifted using the hydraulic device hoisting when entering and exiting the vineyard or to
turn. While mowing, the device is operated in floating position (movable via the long hole in the device
hoisting). When driving up steep inclines, the mulcher cannot be completely lifted as this could allow motor oil
to enter the combustion chamber and cause the motor to stop via the oil warning switch.
When driving on paths, while turning, et cetera, the motor speed is to be reduced to idling using the throttle in
order to bring the cutter shaft driven via the centrifugal clutch.
Inspect the area for objects and obstacles hidden in the grass
and remove these prior to mowing.
While mowing, always operate at full throttle in order to prevent the sliding of the centrifugal clutch and
ensure sufficient traction.
- To turn off the gasoline motor, first reduce the speed to idling and then turn off the motor using the short
circuit switch.
The gasoline valve should remain closed while the mulcher is being transported.
- Close the 3-way valve to turn off the oil motor.

General Safety Instructions
1. Operator’s Obligation to Exercise Diligence
The Combination Mulcher was designed and constructed under consideration of a risk analysis and after
careful selection of the harmonized norms to be maintained, as well as additional technical specifications.
It is state of the art and guarantees a high measure of safety.
This safety, however, can only be reached during operational use when all measures required for it are met.
The planning of these measures and the examination of their execution falls under the operator’s obligation
to exercise diligence.
The operator must especially ensure that:
-The machine may only be used for its designated purpose (see Production Description section)
-The machine can only be operated in faultless, fully functional condition and the safety devices must
especially have their functionality regularly inspected
-The required personal protective equipment for the operating, maintenance and repair personnel must be
available and be used
-The operation manual must always be available in a complete and readable condition at the location
where the machine is used
-Only sufficiently qualified and authorized personnel may operate, maintain and repair the machine and
who are familiar with the operation manual and particularly the safety instructions located within it.
-All safety and warning notices placed on the machine are not removed and remain legible
2. Explanation of the Symbols Used
The following safety symbols are used in this operation manual. The symbols should, above all, make the
