3. SAFETY
3.1 Allowed use
DUO flail mowers, as described in this instruction and maintenance booklet, have been specifically designed to mow
grass, weeds, and light brush up to 1" diameter. Any other use jeopardizes the operator's safety and the machine
integrity.
3.2 Improper use
The mower was designed to mow grass, weeds, and light brush only. Only operate this mower on a properly sized
and equipped tractor.
When using DUO flail mowers, it is particularly forbidden:
• The attachment to tractors of unsuitable power or weight.
• To use other than 1000 R.P.M. PTO speed.
• To work in excessively stony grounds.
• To work on excessive slopes.
• To approach the machine when wearing inappropriate work clothing.
• To get on the machine while it is being used or transported.
WARNING
Operating this mower in an application for which it is not designed and/or operating with the wrong size tractor can
cause mower component damage and equipment failure resulting in possible serious injury or death.
3.3 Safety in the workplace
Most of the accidents which take place while the operator is using the machine or the equipment or during their
maintenance or repair are caused by a lack of compliance with the basic safety precautions. It is necessary,
therefore, to become more and more conscious of the potential risks of one's action by constantly paying attention
to its effects.
If potentially dangerous situations are known, accidents can be prevented!
OPERATOR'S REQUIREMENTS
Physical: Good eyesight, coordination and capability of carrying out all functions required for the machine's use.
Mental: Capability of understanding and applying the established rules and safety precautions. Users must pay
attention and be sensible for their own and other people's safety.
Training: Users must have read and studied this manual, its eventual enclosed graphs and schemes and its
identification and danger plates. They must be skilled and trained on any use or maintenance activities.

WORK CLOTHING
When working and especially when executing repair or maintenance activities, it is necessary to wear the following
clothing and safety accessories:
• Overalls or other comfortable clothing, not too loose to prevent the possibility that parts of them might be
caught in the moving parts.
• Protective gloves for hands.
• Protective glasses or faceplate to protect eyes and face.
• Protective helmet for the head.
•Safety shoes
Wear only personal safety accessories in good condition and complying with the rules in force.
3.4 General safety rules
ALWAYS CONSIDER THE FEATURES OF THE AREA WHERE WORK IS TAKING PLACE:
When the equipment is running, it is forbidden to stand within the field of action of the shredder or of the other
accessories of which it is provided with.
PREPARE THE WORK:
• Before and when working, do not drink alcohol, take drugs, or any other substances which may alter your
capability of working with machine tools.
IMPORTANT
Be sure to have sufficient fuel, to prevent a forced stopping of the machine, maybe during a critical movement.
• Do not use the equipment under unsafe conditions. For instance, it is forbidden to execute makeshift repair
activities just to start working; it is forbidden to work at night with an insufficiently illuminated working area.
• NEVER operate implement without all shields in place and in good operational condition. The operator must
be familiar with the mower and tractor and all associated safety practices before operating the mower and
tractor.
WHEN WORKING OR DURING THE MAINTENANCE ACTIVITIES IT IS NECESSARY TO REMEMBER:
• The labels and stickers providing instructions and pointing out the dangers, must not be removed, hidden, or
made illegible.
• Do not remove, except in case of maintenance, the shields, guards, and deflectors equipped on the mower.
When it is necessary to remove them, stop engine, handle with care and reassemble them properly before
restarting the engine and using the equipment. The mower is equipped with protective deflectors to prevent
objects being thrown from the mower by the blades, however, no shielding is 100% effective. All shields,
guards, and deflectors equipped on the mower must be maintained in good operational condition.
• It is forbidden to lubricate, clean and adjust the moving parts while they are running.
• During maintenance or adjustment activities on the equipment it is forbidden to use hands for executing
operations for which there are specific tools.
• Do not use tools in bad condition or inappropriately, for instance pliers rather than monkey spanners, etc.

• When maintenance or repairs are completed check out that no tools, wiping rags, or other materials are left
inside spaces or guides with moving parts.
• While using the equipment, it is forbidden to make more than one person give directions and make signals. The
eventual directions and signals relating to the load handling must be given by one person only.
• Do not unexpectedly call an operator while he is working if not necessary; it is forbidden as well to frighten or
throw objects at the operator, even if just for fun.
• Watch out for those who are present, especially the children!
• Do not make people get on the machine.
• When the equipment is not needed, stop the vehicle's engine, park it on flat ground with first speed and
parking brake on, with the machine rested on the ground and PTO disengaged.
• Do not clean, lubricate, repair or adjust with the engine running and the machine lifted.
• Never use the machine on steep slopes which may jeopardize the equipment's stability.
The manufacturer declines all responsibility for a lack of compliance with these instructions.

4. OPERATION
4.1 Attachment to the tractor
Before operating the mower, carefully read this Operator's Manual, completely understand the safety instructions,
and know how to operate correctly both the tractor and the PTO shaft, reading carefully the instruction manuals of
the tractor and PTO shaft manufacturers.
All DUO flail mowers have been manufactured to be attached to any tractor provided with hydraulic and universal
3-point hitch.
The tractor used to operate the mower must have the power, capacity, and required equipment to safely operate
the mower. Operating the mower on improperly sized and equipped tractors may cause tractor and/ or mower
damage and could be a potential danger to the operator and passers-by.
Before attaching the equipment to the tractor, set both on a flat and smooth ground and make sure that nobody is
standing between them.
Move slowly the tractor towards the flail mower by aligning the tractor hydraulic lift arms to the two mower hitches'
lateral brackets; stop engine and set parking brake.
Connect first the lower arms by removing the release pins of the brackets placed on the plates, inserting the lift arms
into the arms center and fastening them with the relevant release pins, which had been removed.
Connect, then, the tractor top link to the third upper point by removing the pin located between the plates, inserting
the top link itself and locking it with the pin.
