VERIFICATION OF WARRANTY REGISTRATION

DEALER WARRANTY INFORMATION & REGISTRATION VERIFICATION

It is imperative that the selling dealer registers this machine with Twose of Tiverton 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 Twose web site at www.twose.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 Twose Office on 01884 253691.

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 Twose of Tiverton 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.

Width folded:

For transport the whole machine is within tractor width.

Height and length:

When folded for transport these dimensions will vary according to tractor and cab.

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 if any window is left open.

SAFETY

INFORMATION

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 (P TO) 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.

6

▲ 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
