INTRODUCTION

This manual is to be considered part of the machine. Distributors of new and used
machines are required to issue a document stating that the user ’s manual has been
delivered along with the machine itself. Operators are strongly required to read the
manual thoroughly and carefully before undertaking any kind of operation on the
machine.

AIM OF THE MACHINE

The R500bio-shredder is a machine designed for professional uses. It is particularly
suitable for the treatment of bulk material. It grinds up all sorts of vegetable waste
(pruning and garden waste, hedges, fruit and vegetable waste, wooden boxes, wooden
packages, pallets and so on). When working, it always considers the size, the quantity
and the quality of the material to be shredded.

WARNINGS AND SAFETY DIRECTIONS

Operator’s safety measures

People under the age of 16 are not allowed to use the shredders.
When attending the machine, the user is responsible for any damages, which might
occur to third parties.
During the shredding sessions it is absolutely necessary to wear protective gloves and
glasses. It has been proved that, following an uninterrupted use, the allowed noise
level is exceeded. It is therefore advisable for the user to wear ear-protection devices,
too.
During the shredding session the user always has to wear robust shoes and long
trousers.
Hair must be gathered up.
Do not use the machine if you are tired, ill or if you have taken medicines, drugs as
well as if you have been drinking alcoholics.
When the machine is working, please do not use ladders or stools to get to the driving
roller located at the bottom of the hopper, unless the machine is off.
Do not approach the working area of the cardan shaft transmission when it is
working.
Please use cardan shaft transmission gears provided with a free wheel device. The
transmission-gears must be in compliance with the regulations envisaged by the
machine guideline.

Safety measures concerning the machine

When starting the machine, please make sure that all its parts are assembled correctly .
Replace the broken or the damaged parts before using the machine.
The machine has to be placed on a flat and steady base.

Before leaving the shredder unattended, it is necessary to stop the tractor and to
disconnect the transmission shaft.
It is compulsory to use the machine with all its safety devices correctly mounted to it.
Roll the discharging conveyor belt completely open and turn it on before starting
introducing the material.
Never modify the machine.
Do not use the machine for purposes, which are different than the ones it was
designed for

Safety measures during the shredding session

When using the bio-shredder, the operator must wear the individual safety devices; he
must stay close to the hopper into which he inserts the material he wishes to grind up.
He has also to make sure that nobody is around within radium of 20 meters.
Please do not insert branches having bigger sizes than the foreseen ones (18 cm as
stated in the picture graph on the hopper).
Please do not insert any stones, metals, glass, plastic, earth, and newspaper bundles
and so on in the bio-shredder but only vegetable materials.
Do not remove any protection housing when the machine is working.
The operator shall keep off the discharging conveyor belt when the machine is
working.
Do not get close with any parts of your body to the protection housings.
When the machine is working, do not let any parts of your body get close to the
transmission-gear. The PTO of the tractor has to revolute at an approximate speed of
540 revolutions/minute. Please do not let it revolute faster than that.

Safety measures when maintaining

For the maintenance of the machine, please follow the procedures mentioned in
MAINTENANCE.
Use original spare parts only.
When replacing the hammers and when carrying out the cleaning processes, please
watch out not to cut yourself. "Cutting-heads are very dangerous!"
Start carrying out the maintenance only after you have worn protective gloves and
stopped the tractor; wait until the rotor has come to a complete stop.

Safety during transport and storage

Please make sure that all parts of the shredder are well fastened to the trailer not to
lose anything during transport.
