2.2 Introduction to safety at work
2.3 Safety rules and residual risks
Safety was the primary objective
when designing the machine; nonetheless opera-
tors' 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 situ-
ations 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 guaran-
teeing 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, highlight-
ing some, and not necessarily all, important rec-
ommendations for each one: further recommen-
dations (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:

7

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 chang-
ing 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 siz-
es 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 protec-
tions

not touch the ground
- Take care to correctly angle the PTO shaft ac-
cording to the indications in chapter 4.2.3
- Start the tractor PTO at moderate speed,
selecting the speed prescribed for the mulcher
(540 or 1000 rpm). In case of hydraulically driven
machine, feed the pump/s.
- Increase engine speed to gradually reach the
nominal rpm (540 or 1000 rpm)
- Lower the machine to the desired depth by acting
on the tractor lift or on the position of the com-
pacting roller.
- Advance by pulling the machine (normally in
forward gear) to till the soil and to crush the
- Turn off the main switch when work is over to
avoid discharging the battery.
- Connect the system following the instructions in
point 4.2.5.
- Turn on the main switch. The switch lights up.
- Turn on the fan switch. The switch lights up.
- Check operation of the thermometer and of the
fan.
5.3 Starting cooling system:
If the transmission temper-
ature exceeds 90°, stop the
machine and check the cooling
system. Never work without
the cooling system and tem-
perature sensor running!
The performance capacity of
the machine must NEVER be
exceeded.

6.1.1 Setting the cogbelts
The precise alignment of the cogbelt pulleys is
very important to guarantee long life.
To align them:
-Bring the belt to the desired tension, as de-
scribed above, without tightening the screws
-Only tighten the screws at the side
The operator is responsible
of making sure no persons or
objects are in the machine's
range of action!
5.5 Safety distances
The following safety distances must be respect-
ed for all forestry tillers/stone crushers
30 m 30 m
15m15m
All maintenance on the ma-
chine must be carried out with
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 frequen-
cy can also be used instead of
a belt tension gauge. (Smart-
phone)
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 de-
scribed 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.

6.2 Lubrication
6.2.2 Changing oil
Before starting lubrication, clean all the lubri-
cation points with a rag.
Use grease pumps with clean nozzles to avoid
introducing impurities into the lubrication
points.
After the first 50 hours, and then every 500
hours, it is necessary to change the gearbox oil.
Respect the following levels:
- Gearbox
During a test start, always
remain a safety distance away
of at least 2 m and NEVER turn
the adjustment screws while
the machine is running. Wait
for it to come to a full stop
before resuming maintenance.
6) Repeat the points above until the pulleys are
perfectly aligned
7) The pulleys are perfectly aligned when the belt
remains in the middle of the pulley

them immediately, as well as
safety stickers if damaged or
missing.
6.3 Oil leaks
6.5 Replacing tools
6.4 Safety devices and information
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
