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.

ZMT Owner’s Manual

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.

Figure 4

ZMT Owner’s Manual

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

with lifting capability suitable to the weight of

the machine (see Table 1) and with proper

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.
