IMPORTANT
VERIFICATION OF WARRANTY REGISTRATION
DEALER WARRANTY INFORMATION & REGISTRATION VERIFICATION
It is imperative that the selling dealer registers this machine with McConnel Limited before
delivery to the end user –failure to do so may affect the validity of the machine warranty.
To register machines go to the McConnel Limited web site at www.mcconnel.com, log
onto ‘Dealer Inside’ and select the ‘Machine Registration button’which can be found in
the Service Section of the site. Confirm to the customer that the machine has been
registered in the section below.
Should you experience any problems registering a machine in this manner please contact
the McConnel Service Department on 01584 875848.

NOTE TO CUSTOMER / OWNER
Please ensure that the above section above has been completed and signed by the selling
dealer to verify that your machine has been registered with McConnel Limited.
IMPORTANT: During the initial ‘bedding in’ period of a new machine it is the customer’s responsibility
to regularly inspect all nuts, bolts and hose connections for tightness and re-tighten if required. New
hydraulic connections occasionally weep small amounts of oil as the seals and joints settle in –where
this occurs it can be cured by re-tightening the connection –refer to torque settings chart below. The
tasks stated above should be performed on an hourly basis during the first day of work and at least
daily thereafter as part of the machines general maintenance procedure.

Noise
The equivalent daily personal noise exposure from this machine, measured at the operators’ ear, is
within the range 78 – 85 dB.
These figures apply to a normal distribution of use where the noise fluctuates between zero and
maximum. The figures assume that the machine is fitted to a tractor with a quiet cab with the
windows closed in a generally open environment. We recommend that the windows are kept closed.
With the cab rear window open the equivalent daily personal noise exposure will increase to a figure
within the range 82 – 88 dB.
At equivalent daily noise exposure levels of between 85 and 90 dB, ear protection is recommended; it
should be used at all times if any window is left open.

SAFETY INFORMATION
This machine has the potential to be extremely dangerous, in the wrong hands it can kill or
maim. It is therefore imperative that the owner, and the operator of this machine, read the
following section to ensure that they are both fully aware of the dangers that do, or may
exist, and their responsibilities surrounding its use.
The operator of this machine is responsible not only for their own safety but equally for
the safety of others who may come into the close proximity of the machine, as the owner
you are responsible for both.
POTENTIAL SIGNIFICANT DANGERS ASSOCIATED WITH THE USE OF
THIS MACHINE:
▲Being hit by debris thrown by rotating components.
▲Being hit by machine parts ejected through damage during use.
▲Being caught on a rotating power take-off (PTO) shaft.
▲Being caught in other moving parts i.e.: belts, pulleys and cutting heads.
▲Electrocution from Overhead Power Lines (by contact with or ‘flashover’ from).
▲Being hit by cutting heads or machine arms as they move.
▲Becoming trapped between tractor and machine when hitching or unhitching.
▲Tractor overbalancing when machine arm is extended.
▲Injection of high pressure oil from hydraulic hoses or couplings.
▲Machine overbalancing when freestanding (out of use).
▲Road traffic accidents due to collision or debris on the road.
BEFORE USING THIS MACHINE YOU MUST:
▲Ensure you read all sections of the operator handbook.
▲Ensure the operator is, or has been, properly trained to use the machine.
▲Ensure the operator has been issued with and reads the operator handbook.
▲Ensure the operator understands and follows the instructions in operator handbook.

5
▲Ensure the tractor front, rear and side(s) are fitted with metal mesh or polycarbonate
guards of suitable size and strength to protect the operator against thrown debris or
parts.
▲Ensure tractor guards are fitted correctly, are undamaged and kept properly
maintained.
▲Ensure that all machine guards are in position, are undamaged, and are kept
maintained in accordance with the manufacturer’s recommendations.
▲Ensure flails and their fixings are of a type recommended by the manufacturer, are
securely attached and that none are missing or damaged.
▲Ensure hydraulic pipes are carefully and correctly routed to avoid damage by chaffing,
stretching or pinching and that they are held in place with the correct fittings.
▲Always follow the manufacturer’s instructions for attachment and removal of the
machine from the tractor.
▲Check that the machine fittings and couplings are in good condition.
▲Ensure the tractor meets the minimum weight recommendations of the machine
manufacturer and that ballast is used as necessary.
▲Always inspect the work area thoroughly before starting to note obstacles and remove
wire, bottles, cans and other debris.
▲Use clear suitably sized warning signs to alert others to the nature of the machine
working within that area. Signs should be placed at both ends of the work site. (It is
recommended that signs used are of a size and type specified by the Department of
Transport and positioned in accordance with their and the Local Highways Authority
guidelines).
▲Ensure the operator is protected from noise. Ear defenders should be worn and tractor
cab doors and windows must be kept closed. Machine controls should be routed
through proprietary openings in the cab to enable all windows to be shut fully.
▲Always work at a safe speed taking account of the conditions i.e.: terrain, highway
proximity and obstacles around and above the machine.
▲Extra special attention should be applied to Overhead Power Lines. Some of our
machines are capable of reach in excess of 8 metres (26 feet) this means they have the
potential to well exceed, by possibly 3 metres (9’ 9”), the lowest legal minimum height
of 5.2 metres from the ground for 11,000 and 33,000 volt power lines. It cannot be
stressed enough the dangers that surround this capability, it is therefore vital that the
operator is fully aware of the maximum height and reach of the machine, and that they

6
are fully conversant with all aspects regarding the safe minimum distances that apply
when working with machines in close proximity to Power Lines. (Further information
on this subject can be obtained from the Health & Safety Executive or your Local
Power Company).
▲Always disengage the machine, kill the tractor engine, remove and pocket the key
before dismounting for any reason.
▲Always clear up all debris left at the work area, it may cause hazard to others.
▲Always ensure when you remove your machine from the tractor that it is left in a safe
and stable position using the stands and props provided and secured if necessary.
WHEN NOT TO USE THIS MACHINE:
▲Never attempt to use this machine if you have not been trained to do so.
▲Never uses a machine until you have read and understood the operator handbook, are
familiar with, and practiced the controls.
▲Never use a machine that is poorly maintained.
▲Never use a machine if guards are missing or damaged.
▲Never use a machine on which the hydraulic system shows signs of wear or damage.
▲Never fit, or use, a machine on a tractor that does not meet the manufacturer’s
minimum specification level.
▲Never use a machine fitted to a tractor that does not have suitable front, rear and
side(s) cab guarding made of metal mesh or polycarbonate.
▲Never use the machine if the tractor cab guarding is damaged, deteriorating or badly
fitted.
▲Never turn a machine cutting head to an angle that causes debris to be ejected towards
the cab.
▲Never start or continue to work a machine if people are nearby or approaching - Stop
and wait until they are at a safe distance before continuing. WARNING: Some cutting
heads may continue to ‘freewheel’ for up to 40 seconds after being stopped.
▲Never attempt to use a machine on materials in excess of its capability.
▲Never use a machine to perform a task it has not been designed to do.

7
▲Never operate the tractor or machine controls from any position other than from the
driving seat, especially whilst hitching or unhitching the machine.
▲Never carry out maintenance of a machine or a tractor whilst the engine is running –
the engine should be switched off, the key removed and pocketed.
▲Never leave a machine unattended in a raised position – it should be lowered to the
ground in a safe position on a level firm site.
▲Never leave a tractor with the key in or the engine running.
▲Never carry out maintenance on any part or component of a machine that is raised
unless that part or component has been properly substantially braced or supported.
▲Never attempt to detect a hydraulic leak with your hand – use a piece of cardboard.
▲Never allow children near to, or play on, a tractor or machine under any
circumstances.
Although the information given here covers a wide range of safety subjects, it is impossible
to predict every eventuality that can occur under differing circumstances whilst operating a
machine of this type. No advice given here can replace ‘good common sense’ and ‘total
awareness’ at all times, but will go a long way towards the safe use of your Twose machine.

INTRODUCTION
The Twose series Boom Flail Trimmers has been designed with both the farmer and the
contractor in mind - which has resulted in a boom flail with a very high specification -
with many features not found on other machines.
The construction is of welded steel fabricated assemblies - with many and varied options
available covering such things as controls, hydraulics, heads, booms etc. The cutting head
is of a ‘double skin’ construction.
The cutting flail blades offered for your Twose Series machine are: -
a) Heavy, double edged design (one piece).
-For ‘Upward’ or ‘Downward’ cutting.
-Suitable for all types of conditions and growth.
b) Back to Back ‘rigid’ one piece blade (in pairs).
-For ‘Upward’ or ‘Downward’ cutting.
-Suitable for grass/mowing and trimming.
Illustration shows both a single blade and pair of blades back to back.
c) Heavy single edge blade flail (twisted pattern).
-Cuts one direction only.
-For grass cutting and hedge trimming.
d) Back to Back - on shackle (in pairs).
-For ‘Upward’ or ‘Downward’ cutting.
- Suitable for grass/mowing.
e) Boot flail - on shackle.
-Cuts one direction only.
-For grass cutting and hedge trimming.

The cutter head design is of a ‘double skin’ construction for greater strength and longer
life. The drive is by means of ‘vee’ belts from the hydraulic motor to the rotor, with the
drive completely contained within the width of head for a cleaner cut.
Twin ‘vee’ belts take the drive from the motor to the rotor - giving a reliable drive with the
added benefit of anti-shock protection that a belt drive system provides.
A ‘swing link breakback’ system is built into the machine; this offers a degree of
protection to machine components if an obstruction is encountered during normal work.
Two parking stand legs are fitted to the machine, which once the machine has been
attached to the tractor should be folded away in the ‘stow’ position.
The machine has ‘angle head flotation’ as standard –this is engaged by moving the head
rotation lever beyond the normal actuation range into a detented ‘float’ position. Lift float
is available as an option on the machine.
All machines have a relief valve in the primary ram system, this limits the pressure which
can be generated in the drop side of the cylinder – the cutting head cannot therefore be
‘driven’ into the ground in any circumstances.
