2.2 Introduction to safety at work
2.3 Safety rules and residual risks
Safety was the primary objective
when designing the machine; nonetheless operators' carelessness can invalidate the efforts of the
designers.
The machine was designed and built with the
intention of eliminating as many risks as possible
for the user.
However, considering the variability of the situations as well as foreseeable misuse, there are
residual risks which cannot be eliminated, either
for functional purposes or because they do not
depend directly on the machine.
Information on residual risks is aimed at guaranteeing that the user take the protective measures
which, for example, can include adopting safe
work procedures, restricting tasks to trained and
authorised operators, etc.
We shall describe some of these risks, highlighting some, and not necessarily all, important recommendations for each one: further recommendations (or these) are included in other chapters,
either general or related to a specific operation.
Thereby SEPPI M. S.p.A. will not be held liable in
case of:
6
Always - reduce speed or interrupt work whenever gripping to the ground is reduced (strong slope, presence of mud, snow, etc.). Pay the utmost attention when changing direction on slopes or slippery ground.
Always - be extremely cautious when the work area is not completely visible (inspect the area before working). Only work with natural light and good visibility.
Always - check that the weight which the tractor can lift is compatible with that of the equipment. Conduct tests to check the driving stability of the tractor. With the
machine connected and lifted from the ground at least 20% of the weight of the tractor must rest on the front axle or, for machines mounted at the side, 10% on each
wheel on the side opposite the stone crusher.
Always - before detaching machine from the tractor, engage the parking brake and make sure the tool is stable.
Always - make sure that passages on roads, through gates, etc. are sufficiently wide so that the tractor with the applied tool can pass.
1)
Risk of losing adherence (with the possibility of the tractor rolling over)
To reduce the likelihood of risk to a minimum, strictly follow these instructions:
Never - abandon the tractor's driver seat and approach the machine before the blade holder rotor is stopped and the tractor stopped in safe conditions. Caution! The
rotor can continue to rotate for 5 minutes after the PTO has stopped due to inertia.
Never - work with the protections of the transmissions not intact or not in perfect working order. Immediately restore all protections and safety devices when damaged
or worn (stone guards, PTO shaft protection, etc.).
Always - prevent third parties from approaching the machine while running or when the tractor is moving.
Always - disengage the PTO and stop the engine, removing the key from the dashboard before performing any adjustment or maintenance.
3)
Risk of conveying due to pulleys, belts or chains
To reduce the likelihood of risk to a minimum, strictly follow these instructions:
Never - abandon the tractor's driver seat and approach the machine before the blade holder rotor is stopped and the tractor stopped in safe conditions. Caution! The
rotor can continue to rotate for 5 minutes after the PTO has stopped due to inertia.
Always - prevent third parties from approaching the machine while running or when the tractor is moving.
Always - disengage the PTO and stop the engine, removing the key from the dashboard before performing any adjustment or maintenance.
Always - check that the PTO shaft is mounted correctly (safety pin in its seat); appropriate protections on PTO shaft, tool side and tractor side; free wheel device mount-
ed on the tool side (see PTO shaft safety manual).
2)
Risk of conveying due to rotary shafts
To reduce the likelihood of risk to a minimum, strictly follow these instructions:
Never - transit or stop in front of machines in motion and/or with rotor running.
Always - disengage the PTO, close the hood, stop the engine, and remove the key from the dashboard before performing any adjustment or maintenance.

3. TECHNICAL INFORMATION
3.1 Intended use
These machines are suitable to crush various sizes of stones, to till the soil in presence of stumps
and to mulch different sizes of shrubs and trees,
in relation
to the power available for driving
the machines and to their constructive
features (see 3.2).
The machines are hitched to a tractor or
operating machine and driven by the PTO,
by means of the PTO shaft or hydraulic
circuit.
To perform this job, the operator must be
prepared and trained and the tractor must be
hooded to protect the frame and cab. All the
structural parts of the drive
machine must be reinforced and adapted to
forestry work which requires sturdy protections
suited to protect the operator.
The tractor driver must therefore check that:
- the driver's cab has safety guaranteed regarding
rolling over and falling objects (FOPS/ROPS);
- the windows are safety windows and/or protected
by protective meshes;
- inlet air is filtered;
- the presence on site is signalled by luminous
signs.
The following are prohibited:
- use by personnel not specialised in agricultural
work and informed by reading the manual;
- use the machine for other reasons than that
intended;
- modify any functional/performance feature;
- modify or remove safety devices and/or protections

the tool on the ground and the
tractor stopped, removing the
keys from the dashboard.
Interventions must be carried
out in safe conditions, using
appropriate tools and personal
protective equipment.
6. MAINTENANCE
To check the belt tension, use
a belt tension gauge to detect
belt frequency. A digital guitar
tuner which shows the frequency can also be used instead of
a belt tension gauge. (Smartphone)
To adjust the tension of traditional belts, proceed
as follows:
- unscrew the fixing screws and nuts of the belt
protection,
- after having opened the protection, loosen the
screws and nuts securing the extension to the
frame, without removing them,
- stretch the tie rod to reach the correct belt
tension,
- tighten the screws and nuts loosened in point 2,
- close the belt protections
All the operations not described in this manual can
only be carried out by qualified
and specifically specialised
personnel.
There are three types of lateral transmission:
V-belts, cogbelts and parallel axis gearboxes.
To adjust tension, strike the middle of the belt
with an object and measure the frequency with a
measuring instrument.
Check belt tension every 50 hours, as indicated in
the diagram below.

If any machine component leaks oil, the oil
must be recovered and worn components
restored.
Use original Seppi components for proper
operation of the rotor.
Check the chains, rubbers, guards of the PTO
shaft, etc. every 8 hours
Oil leakage on the ground
causes pollution!
Using non-original spare parts
makes the rotor warranty null
and void.
1) lift the rear hood with the hydraulic controls
and secure it mechanically
against accidental closures

The spare parts can be consulted in the attached
Spare Parts List.
Do not release parts or
fluids of the machine into the
environment and dispose of
them by means of specialised
companies.
9. DISMANTLING, SCRAPPING AND
WASTE DISPOSAL
It is necessary to separate the different types of
materials in order to send them to specific separate waste collection facilities.
As far as metals are concerned, recycling requires
dividing them into steel and other metals or
alloys.
Pay particular attention to electrical products,
plastic or rubber materials, which must be disposed of separately in compliance with standards
in force.
8. CONTROL REGISTER
To testify the correctness of all the inspections
and maintenance performed on the machine, as
described in this publication, it is recommended
to fill in a control register and to keep it updated
during the whole life of the machine, entering
dates, objects undergoing inspections/maintenance and overall hours of use. The maintenance
technician appointed by the customer is in charge
of filling in this register in all its parts
The register complies with that required by the
laws of most Countries, and must contain:
- inspection (even visual) interventions and
routine maintenance, included in the "Main
tenance" chapter or which are necessary to
maintain the machine in good conditions and
efficiency for its safety, regardless of who
performs them;
- extraordinary inspections and maintenance (in
cluding repairs and changes carried out by the
manufacturer), in order to keep the machine in
good conditions whenever exceptional events
occur;
- all activities regarding the life and use of the
machine.
