equipment into which Fullwood equipment is to be incorporated must comply with all applicable
European directives.
The attention of the purchaser is drawn to the provision of Section 6 of the Health and Safety at
Work Act 1974. Section 6 of the Act provides that manufacturers, designers, importers or
suppliers of equipment for use at work have a duty to ensure, so far as reasonably practical,
that the equipment will be safe and without risk to health when properly used. The equipment is
not regarded as being ‘properly used’ if it is used without regard to any relevant information or
advice relating to its use made available by the manufacturer, designer, importer or supplier. It
is the responsibility of the purchaser to take such steps as are necessary to ensure that
appropriate information relevant to the equipment is made available to their employees and any
person to whom the purchaser supplies them.
It is important that the equipment be installed, commissioned, maintained and used by
competent trained/skilled persons in accordance with good engineering practice. International

and national Wiring Regulations, Codes of Practice and all current relevant legislation
requirements and accepted rules or art for the industry concerned.
All installations and maintenance should be carried out within the provisions of ’The Electricity at
Work Regulations, 1989’ and by persons so qualified as defined in that act.
Fullwood Limited supplies document packs with all equipment. These documents are supplied
for information and should be disseminated to the relevant persons.
1.1 Risk Assessment
Risk Assessments are a legal obligation and an important step in protecting your personnel,
visitors as well as your business. It helps you focus on the risks that really matter in your
workplace, the ones with the potential to cause real harm. In many instances, straightforward
measures can readily reduce risks. These measures should be reviewed annually or when the
process changes, whichever comes first. The law does not expect you to eliminate all risk but
measures must be taken to reduce the risk as far as ‘reasonably practicable’.
For most, that means simple, cheap and effective measures to ensure your most valuable asset
– your workforce – is protected.
1.2 General
M²erlin is manufactured to the latest engineering standards and acknowledged safety
regulations. Nevertheless, dangers can arise through its operation;
•Danger to life and limb of the operator or third parties.
•Damages to the machine and other material assets.
Following instructions within this manual will prevent / minimise risk

2.12 Safety devices
•Various safety devices ensure safe working with the machine.
•Emergency Stop buttons on the front of the process cabinet and on the Human
Machine Interface (HMI).
•The robot arm has force sensing technology that has been factory set to minimise
the risk of injury to operators and animals.
•The speed of the robot arm in manual operation does not exceed 250mm/s.
•Do not change, bypass or disable safety devices.
•Regularly check safety devices for their correct function.
•Replace safety decals that are missing or are illegible.
2.13 Power Cut
In the event of a power cut the following will occur:
•The machine will stop and all energy will disperse. (electricity, compressed air,
vacuum, etc.)
•The cups will drop from the teats.
•The exit gate(s) will become free to be pushed/pulled open so that the cow can leave
the crate.
•M²erlin arm will be free to move in both the horizontal and rotational axis allowing the
cow to move it as she leaves the crate.
•The vertical axis will remain at the height when the power was interrupted by the
brake incorporated in the vertical motor. This brake prevents the arm from dropping
in the event of power failure. The brake will hold a force of up to 400kg but must be
avoided as damage to the arm may occur.
•Once power has resumed, the procedure referred to in section 10.2.3 be followed.
•It is the responsibility of the farmer to provide a suitable alternative means of power
in the event of a power cut.
Note: Fullwood will not cover any damage caused by generator, substandard power supplies or
third party equipment.

2.19 Power Supply Specifications
•Fullwood Ltd does not carry out any mains wiring. It is the responsibility of the
customer to arrange for all mains wiring to be carried out by a competent contractor
qualified in accordance with national and/or local legislation. This also applies to any
mains electrical connections from switches of isolators to electrical equipment
supplied by Fullwood Ltd.
•The power requirements will vary significantly, depending on the ancillary equipment
specified.
•Power consumption for all other pieces of equipment e.g.: Air Compressor, Vacuum
pump, Boiler Etc. will need to be calculated and specified per site.
•Earthing; It is the responsibility of the customer to ensure that all metal parts of the
installation are bonded to earth in accordance with local and national legislation.
•M²erlin must be earthed according to local legislation.
•Starting up M²erlin without proper earthing will render the warranty null and void.

•The filters should be located as close as possible to the compressor but after the air
dryer.
•If the compressor has no filtration a 0.1 micron filter must be fitted before the drier
and the remaining filters after the drier
