1GENERAL INFORMATION
1 .1 This operation and maintenance manual is intended for the professional user. It is
mandatory to follow these instructions in order to prevent situations that could
endanger the operator’s and other people’s safety, and to ensure the correct
functioning of the shredder. If you have questions, call “FERRI” after-sales service or
a specialized “FERRI” dealer.
1.2 Identifying the Machine
Each shredder has an identification plate attached; the data necessary to identify the
model and the serial number to order spare parts or after-sales service are both
stamped on the plate (see Figure 1)
Figure 1
1.3 It is strongly recommended to use genuine “FERRI” spare parts to avoid altering the
technical features of the shredder. “FERRI” is not responsible for any damage or
injuries to people due to unauthorized modifications or to the use of non-genuine
spare parts.

3GENERAL SAFETY RULES
3.1 General Safety Rules:
•It is mandatory to read and follow the instructions from the use and maintenance manual
before carrying out any operation or moving the shredder. Improper use or moving it
improperly may seriously damage property and harm people.
•Both the operator and maintenance fitter must know the shredder well, especially
regarding dangers resulting from improper use or incorrect repairs.
•Before starting, check the tractor and shredder in regards to functionality, road safety
and accident prevention rules.
•Even when using the shredder correctly, stones or other objects may be thrown a long
distance. Therefore, nobody should be standing within the danger area. Special
attention must be paid when working near roads or buildings.
•Use tractor with cabs.
•The condition of flails and of all guards must be checked before beginning the daily
work. They must be replaced if damaged or missing.
•During checks or repairs, make sure nobody can start the shredder by mistake.
•Never wear loose or fluttering clothes.
•Never carry passengers on the tractor.
•Never carry passengers on the shredder.
•Never enguage the PTO with the engine stopped.
•Never approach the shredder until the rotor has completely stopped.
•Do not enter the working zone of the PTO shaft while it is in motion. It is dangerous to
approach the rotating parts of the machine.
•Keep the PTO shaft guard in good working order.
•Before starting, check the surrounding area for the eventual presence of children and or
animals.
•DO NOT stand in the range of operation of the machine.
•The PTO shaft must be assembled and disassembled only with the engine is stopped
and the ignition key removed.
•Before connecting the power take-off, check that the speed and rotation direction
corresponds to those of the shredder.
•Before leaving the tractor with the shredder attached, proceed as follows:
1. Disconnect the power takeoff.
2. Put the machine firmly on the ground (with the hydraulic lift).
3. Apply the hand brake and if the ground is sloping steeply, wedge the tractor
wheels.
4. Take the ignition key out.
•Immediately replace any safety sign or missing, damaged decal.

ZMT Owner’s Manual
3.2 Safety Rules Concerning the Hydraulic System
•This shredder uses the hydraulic circuit of the tractor to carry out side movements
and to adjust the flail head; the pressure of such system must not exceed 190 BAR.
•Mark the different pipes to avoid reversal of operation.
IMPORTANT: Do not look for oil leaks with bare hands, but always while wearing
gloves or with a cloth. Oil under strong pressure may seep into the skin causing
serious infections. In this case contact a doctor immediately.
•Periodically check the flexible hoses; if they are worn or damaged they must be
replaced with others of the same specification.
•Before working on the hyudraulic system, lower the machine, take pressure out
and stop the tractor.
•Used oils and greases must be stored and disposed of according to anitpollution
rules.
3.3 Safety Rules Concerning Road Traffic
•In transport, reduce speed, especially on bumpy roads. The weight of the shredder
may render driving difficult and damage the shredder itself.
•Check that the levers which operate the hydraulic lift are locked to avoid the
lowering of the machine during transport.
•When driving on public roads, respect all road rules in force. Never transport the
shredder with the rotor moving, even for short distances.
•Lock the shredder with the appropriate chain.
3.4 Safety Rules During Use
•Pay special attention, when working with the machine, not to touch fixed objects
such as road drains, wells, shafts, curbs, guard rails, tracks, etc. This could cause
the breakage of the flails, which can be thrown at very high speed.
•If wires, ropes or chains should get entangled in the rotor, stop immediately to
prevent damage or a dangerous situation; stop the rotor and the tractor, take out
the ignition key.
Put working gloves on, clear the rotor with the aid of pliers or shears. Do not try to
disentangle by inverting the rotational direction of the rotor.
•Do not use the machine when there is vibration in the flail head, as this could
cause breakage and serious damage. Find the cause of the vibration and repair it.
•Do not operate with the arm extended if the tractor is on a sloping ground.

3.6 Description and Location of Safely Decals (Figure 5)
Carefully follow the instructions detailed on the decals.
Description of the Decals
1. Warning of danger through lack of knowledge of all the functions of the machine
and the resulting risks: read the use and maintenance manual before operating
the shredder.
2. Danger sign of crushing or shearing: do not put limbs in the moving parts of the
machine where this decal is located.
3. Danger sign: it shows the risk of flying stones or other objects and it is mandatory
to keep out of the danger zone.
4. Danger sign of rotating flails: do not enter the area of operation with hands or feet.
5. Danger of getting entangled: do not approach the rotating PTO shaft. Pay special
attention to clothes which must not be loose or fluttering.
6. Danger of crushing: keep out of the danger zone. Before you make any
adjustments or perform maintenance it is neccesary to lock the hydraulic cylinders.

4. INSTRUCTIONS FOR INSTALLATION AND
HANDLING
4.1 Lifting and Unloading
To handle the shredder use a hoist or a crane

chains and type approved hooks attach them
to the marked points, as shown in Figure 6.
4.2 Packing
To make transport easier, the shredder can be supplied in a special pack
(disassembled and on pallets).
In this case, a card showing the reassembling procedure will be attached to the Use
and Maintenance Manual.
